The quality of the heating system directly affects the comfort of a private home. The heating system must be given due attention, since being in a room, especially in winter period, it will take a long time. Today, more and more consumers are choosing alternative heat sources for their homes.

Alternative heating sources are systems that work with heat generators using renewable energy sources. These are solar, geothermal and biological energy. Boilers, heat pumps and solar panels are used to store heat and generate electricity.

This is what a biofuel boiler looks like.

Alternative heating systems of each type have their own difficulties and features. Less problems occurs when using gas and electric boilers. The main advantage is a constant supply of fuel. It’s enough to connect the boiler once, set it up yourself, and not worry about running out of fuel in the middle of the night. Of course, there is no insurance in case of interruptions or emergencies, but this rarely happens.

Heating a house with water-to-water heat pumps

These heating methods require a well to collect groundwater and to drain waste water back into the ground. For a small private house, a consumer will have to drill 2-3 such wells for water intake and 1-2 for waste drainage. The drilling depth must be 50 m. It is also necessary to obtain permission from government control services.

External view of the water-water pump.

Heating with brine-water heat pumps

To implement the project, it is necessary to drill a well up to 200 m in depth. It should contain pipes along U shape along with the solution. You can arrange a heat exchanger that will be located at a depth of at least 5 m. This is necessary to reduce the difference in the heat received in different months of the year.

Heating circuit based on a brine-water pump.

The depth and number of wells are determined based on the ability to obtain the required 50 W of thermal energy. It is obtained from each linear meter of a drilled well. As a result, alternative heating of a private house using heat pumps according to the water-water or brine-water scheme is characterized by minimal heating costs compared to indicators characterizing other types of heating systems.

Heating a house with solar heat storage collectors

Alternative heating using solar heat storage panels will directly depend on the intensity of the sun's rays, which varies at different times of the year. At night and in cloudy weather, there is not enough solar radiation to operate the collectors.

What is it used for?

Solar panels often used to heat water or for domestic and household needs. Hot water takes part in heat exchange in monovalent storage tanks. Solar panels can act as an additional source of thermal energy generation for water heating and heating systems in biovalent storage tanks.

Types of solar collectors

Solar collectors are divided into two types:

• flat;
• having a vacuum pipe.

Heating with solar panels.

If the equipment is used in the summer, the performance coefficient of both types will be the same. For winter it is recommended to use vacuum manifolds. They can operate at temperatures down to -35 degrees.

Flat-plate collectors are capable of heating air up to +60 degrees. Vacuum collectors are designed for heating up to +90. In other parameters the devices are similar.

Collectors with vacuum pipes are ideally used as alternative heating country house. At the same time, the devices can heat water.

TEK

Hydrodynamic water heating unit is another good alternative gas heating. It is not yet very famous, but its simplicity and advantageous use for heating a house makes it noticeable. In addition to water, the installations allow heating oil, salty and dirty water.

Design

The installation consists of a water heating expansion tank, a pump, and an electric pump. Heating occurs when the streams of water supplied to the tank collide with each other - it is released thermal energy. When heating a room, the water heating unit is connected to heating system private house, no additional installation of a circulation pump is required; a boiler is connected to heat the water.

Principle of operation.

Ventilation

The use of ventilation as a source of heating, at least, sounds interesting, because the purpose of ventilation is to remove air from the premises, which contains dust, there is a deficiency of oxygen and the presence of unpleasant odors. But some of the heat is also removed with the air. How can this be used? You can also install a heating element into the ventilation system (in its supply part) with your own hands to supply heated air to the house.

The supply and exhaust ventilation system is most effective when forced circulation and heat recovery.

The systems use warm exhaust air to preheat cold, supply air. The best efficiency and equipment utilization rates are achieved by regulating the air flow according to its actual need.

From biomass, which includes organic waste, manure, plants, wastewater, biogas is obtained as a result of decomposition with the help of bacteria. Low-rise buildings It is advisable to heat with wood pellet chips, logs, and pressed waste from the woodworking industry. Fuel is supplied to the boilers using various ways automated feeding. As for boilers operating on logs, fuel is loaded into them manually.

Alternatives to gas heating also include pallet boilers. They can be with either manual or automatic fuel supply. This ensures that a person does not need to be near the boiler all the time. The automatic control system maintains the temperature at a certain parameter.

This is what biofuel looks like.

Heating the house with boilers that run on waste oils

Waste oils are not related to renewable energy sources, however, they take part in the formation of materials that need to be recycled.

Warm floor system

The well-known heating scheme – “warm floor” – is perfect for heating a country house. During installation, no additional redevelopment will be required. You can save significant amounts of money on heating. The system is installed under the floor covering. If you have the necessary knowledge and skills, you can install a heated floor yourself.

The process of installing heated floors.

Ceiling heaters

Another alternative for heating a country house is the installation of special ceiling film heaters. For example, foil, which is simply mounted on the ceiling. Under the influence electric current There is an even distribution of heat throughout the room.

Since every year there is an inexorable increase in prices for various coolants, alternative home heating is becoming more and more relevant. Owners of private houses or country houses They are looking for a wide variety of methods for organizing a heating system. Any heating system option that is not included in the category standard systems, has both its advantages and disadvantages.

Types of alternative heating

For many owners of private or country houses, refusing such a system that runs on gas is already a alternative solution. Many strive to organize a completely autonomous heating system that can accumulate heat from the sun's rays.

Those who care about nature and the environment choose environmentally friendly heating systems. For many, such an indicator as air humidity in the house when a particular system is operating is also important.

Natural energy sources are now available for organizing various heating systems, but they are quite expensive.

Of course, they will pay off in 8-10 years, but not everyone is happy to wait that long. Judging in general, all modern alternative heating systems for a private home are distinguished by their great variety. Among the alternative devices necessary for organizing a heating system are the following:

• Boilers operating on liquid fuel or solid type, as well as on fuel of biological origin.
• Heat pumps that operate using geothermal energy.
• Solar collectors that are capable of collecting heat from the sun's rays.
• Various infrared heaters.

Not so long ago, a device such as a “warm floor” could be considered an alternative heating option for a home. It appeared on the market relatively recently, but many already classify heated floors as conventional systems.

Some people still prefer traditional heating systems because they think that such systems cannot cause problems. Some people mistakenly believe that gas heating systems are characterized solely by their advantages. Today, thousands of homes are heated using such heating systems, but at the same time, the requirements for the quality of such systems are growing.

Connecting a gas boiler to the mains is not a simple process. Besides the fact that it is quite difficult technological process, before connecting the heating system to the main line, you need to collect some documents. Another disadvantage of gas heating is the constant increase in gas tariffs.

The quality of such a heating system is also not always satisfactory and meets the requirements of private home owners. The boiler does not heat the room as evenly as possible. The temperature in the part of the room where the radiators are located will always be higher than the temperature in the central part of the room.

Biofuel boilers

If you intend to change gas system heating for alternative heating of a private house, then there is no need to organize it from scratch. Very often all that is required is to replace the boiler. The most popular are boilers that run on solid fuel or electric boilers. Such boilers are not always profitable in terms of coolant costs. Special attention should be given to boilers that run on fuel of biological origin. To operate the heating system, in the center of which there is a biofuel boiler, special pellets or briquettes are required. However, other materials can be used, such as:

• granular peat;
• wood chips and pellets;
• straw pellets.

Briquettes are a type of fuel that allows you to organize automatic fuel supply to the boiler.

The main disadvantage is the fact that such alternative heating of a country house can cost much more than a gas boiler and, moreover, briquettes are quite expensive material.

A fireplace can be an excellent alternative solution for organizing a system such as alternative home heating with your own hands. Using a fireplace you can heat a house with a small area, but the quality of heating will largely depend on how correctly the fireplace was installed.

Using geothermal pumps you can even heat big house. To operate, such alternative methods of heating a private home use water or earth energy. Such a system can perform not only a heating function, but also work as an air conditioner. This will be most relevant in hot months, when the house needs to be cooled rather than heated. This type of heating system is environmentally friendly and does not harm the environment.

Solar alternative heating sources for a country house - collectors, are plates installed on the roof of the building. They collect solar heat and, through a coolant, transfer the accumulated energy to the boiler room. A heat exchanger is installed in the storage tank, into which heat is supplied. After this process, the water is heated, which can be used not only to heat the house, but also for various household needs. Modern technologies have made it possible for such alternative views The heating systems of a private house collected heat even in damp or cloudy weather.

However, the best effect of such heating systems can only be obtained in warmer and southern areas. IN northern regions Such alternative heating systems for a country house are suitable for organizing an additional heating system, but not the main one.

If not so long ago solar panels were considered an expensive pleasure, today they are included in the category of more affordable heating methods country cottage or a private house.

Of course, this is not the most available method, but every year its popularity is only growing. Alternative heating of a cottage in this way is the simplest from the point of view of such a science as physics. Solar panels have an expensive price category because the manufacturing processes of photocells are expensive.

Infrared heating and “warm floor” system

Recently, a type of heating that operates thanks to infrared heating devices has become increasingly popular. Such devices are quite easy to install and also come in an affordable price category. In addition to the above advantages, they stand out for their compact dimensions and are able to decorate the interior of any room.

Infrared film, used when installing a system such as “warm floor”, has also recently enjoyed wide popularity.

Its installation is not particularly difficult, since it is laid under such a layer flooring as a decorative layer. In essence, heated floors are no longer an alternative heating system for houses, but sometimes even the main one.

Another system that is gaining popularity is called “ warm baseboard" This system is installed along the walls. The walls heat up first and distribute heat into the room. The walls also prevent heat from escaping. Such a system has the property of uniformly heating the air in all parts of the room. Such alternative sources of home heating are easy to install and do not require large acquisition costs.

What is alternative heating? What is it like, what can serve as a source of thermal energy? Is it possible to install alternative heating in a private house with your own hands?

Let's try to figure it out.

What it is

This name, when used in the press, traditionally refers to all methods of heating a home that were not used twenty to thirty years ago. Geothermal heat sources, film heated floors, biofuel, and infrared heaters are all thrown into the mix.

Within the framework of the article, however, we will allow ourselves to interpret the term much more narrowly.

We are interested in alternative home heating, which:

1. Uses renewable sources of thermal energy as heat, for which you do not need to pay sellers of relevant services or goods. As an option, at least part of the thermal energy is taken from renewable sources.
2. Can be implemented at an acceptable cost. At a minimum - incomparable with the cost of the house itself.

Why is this necessary?

The reason why alternative heating systems for a private home are attracting attention is simple and clear: rising energy prices and, accordingly, electricity. Solar oil, gas, and coal are steadily becoming more expensive.

Useful: mains gas is now cheaper than other types of heating. But it continues to rise in price. Its reserves are limited, so the trend will continue and intensify in the coming years.

Well... don't call the author an idealist, but it is still barbaric to burn fossil fuels or trees to heat the small interior space of your home. In this sense, alternative types of heating are not just economically beneficial. They are progressive.

Implementation options

Solar systems

Solar energy is used to heat homes in two ways:

1. By transforming it into electricity, which can then be used to operate heaters.
2. For direct heating of the coolant, natural circulation or circulation pump then they are driven through radiators or convectors.
   The simplest do-it-yourself alternative heating is precisely the (often homemade) circulation pump and radiator in the house.

The peculiarity of solar systems is obvious: sunny days even in Crimea or Central Asia they still change to cloudy. Nobody canceled the night either. If so, they are unsuitable as constant sources of heat.

What implementation options are possible?

• works in parallel with an electric heater. The coolant temperature is controlled by sensors; When it falls below a certain level in cloudy weather, heating by heating elements is turned on.
• It is equipped not only with a controller and an inverter that generates mains voltage from +12 or +24 volts DC, but also with a high-capacity battery.
  During daylight hours, solar panels store energy in batteries; At night or in cloudy weather, batteries serve as the power source. With the appropriate area of ​​photocells and battery capacity, a completely energy-autonomous system can be realized.
  But here an unpleasant surprise awaits us: we are limited by the level of available storage technologies electrical energy. The best types of batteries will last no more than five years in such a system, and the cost of replacing them will be quite comparable to the cost of electricity purchased from energy companies during this period.
• Finally, the simplest solution that saves electrical energy (and heat) can easily be implemented with your own hands.
  Alternative heating of an apartment or private house (or rather, energy supply, to be precise) in this case is a solar panel with a controller and an inverter, which is connected in parallel to any outlet, and electric heaters of any type.

A caveat: you need a mechanical, disk counter. Electronic ones cannot register the reverse direction of current. In sunny weather, when solar cells produce more electricity than you spend on heating, the meter simply counts down the kilowatt-hours in the opposite direction. The savings are more than noticeable.

Wind energy

The energy generated by a windmill can also be used to produce thermal energy.. Industrial products are sold in large quantities and cost quite reasonable money.

The only obvious feature of this solution is the large size of the impeller. For a 4-kilowatt wind generator it reaches ten meters.

All problems of accumulating electrical energy for heating, characteristic of solar systems, fully apply to wind generators.

• It is clear that alternative heating of a country house using wind energy can only be implemented in those regions characterized by constant moderate winds - primarily in the steppes and on the coasts.
• In addition, if the collector can use solar energy directly to heat the coolant, then the transformation of the mechanical energy of rotation of the windmill first into electricity and only then into heating the air in the room is inevitable. Which, as you might guess, means a decrease in system efficiency.

Heat pumps

Finally, the most versatile alternative central heating are heat pumps. The operating principle of all devices of this type is the same: transfer of thermal energy from a low-potential source to the house. Simply put, a pump takes heat from a cold object and transfers it to a hot one.

This is how all types of heat pumps work. The difference between them is the source of low-grade heat.

All heat pumps are based on the same simple system that can be seen by disassembling any refrigerator: a compressor, a heat exchanger and an evaporator. But a specific implementation can vary greatly, giving a wide variation in the cost of the solution.

Ground-water

Ground-to-water heat pumps are the most versatile in terms of climate zone alternative sources of heating for a country house. The principle of their operation is based on the fact that even in permafrost areas at a depth of several tens of meters, the soil temperature is consistently above zero.

Accordingly, heat exchangers that take heat from the ground are probes immersed in wells. The length of the highways is tens of meters; in addition to the high cost itself heat pump, the price of its installation is impressive.

The cost of drilling one well is estimated at 1500 - 2000 rubles per linear meter; Several wells are being drilled. But you still need to mount the pump itself and immerse the probes...

However, it is somewhat cheaper to install a ground-to-water heat pump with horizontal arrangement collector Heat exchangers are buried in trenches below the freezing level. The downside of this solution is the large area required to install the pump.

The resulting heat is used to heat water, which is used for household needs and to transfer heat to heating devices.

Water-water

If there is flowing groundwater at a shallow depth in your area, the cost of implementing the project for you will decrease sharply.

U running water it is much easier to select the heat we need:

1. You can get by with one immersion heat exchanger probe;
2. The drilling depth may be limited to 10-15 meters.

Air-water

In an air-to-water heat pump, the heat source is the outdoor air. Heat exchanger - radiator with an impressive fin area; it is blown by a low-speed fan.

Such pumps have a much more affordable cost compared to previous ones and are much cheaper to install. However, when the temperature outside drops, their efficiency also drops significantly: it is more difficult to take away thermal energy from cold air.

The COP parameter is the relationship between consumption and thermal power. You can see how it changes at temperatures from +7 to -15.

Air-to-air

Finally, when listing alternative sources of home heating, one cannot fail to mention the absolute record holder for the cheapest project - an air-to-air heat pump. The simplest example of such a device is a conventional split system in heating mode.

Due to the fact that electricity is spent not on heating the air, but on the operation of a compressor pumping heat from the street, heating with an air conditioner is much more economical than a conventional heater.

The best examples of inverter air conditioners (which use reverse conversion of alternating current into direct current and vice versa to change the speed of the compressor) air conditioners pump 5 kW of heat into the house for every kilowatt of electricity spent.

Inverters from a reputable manufacturer cost up to a thousand dollars with installation and are capable of operating at outdoor temperatures down to -25C.

Inverter air conditioner - great solution for temperate climates.

Conclusion

Of course, we have not listed all alternative heating methods. You may be able to find additional information useful to you from the video at the end of the article. Warm winters!

Various energy resources, water and gas become more expensive every year, so apartment and house owners are increasingly thinking about ways to save. Significant savings come from alternative heating of a private home without gas. This and many other systems allow owners to make their homes completely energy independent. There are several types of alternative energy sources, each of which has its own advantages and disadvantages.

The concept of “alternative home heating” characterizes different ways heating supply for housing. Previously they were not used in private households.

Basic conditions for using these types of heat supply:

• To generate thermal energy, renewable energy sources are used that do not require payment of utility bills. In this case, their full or partial use is possible.
• The costs of installing these systems should be quite acceptable and not exceed the cost of the heated building itself.

Common reasons for switching to alternative heating

The main reason why alternative sources of heating a private home are used is the regular rise in price of many types of energy resources. These include gas, natural coal, electricity and other varieties.

Today, gas mains are most often used to heat a private home. The cost of such heating is the most acceptable, but it is constantly increasing. Since gas is an energy resource that will sooner or later run out, the upward trend in prices will continue continuously. In such a situation, alternative heating can be called not only profitable from an economic point of view, but also progressive, since renewable resources are used as heat sources. As a result, wood and non-renewable fossil resources are not consumed.

Types of alternative heating, their pros and cons

Wind, solar, heat from the bowels of the earth, human waste and industrial waste are used as alternative resources. It is also important that the use of these resources does not lead to environmental pollution, because they are natural and environmentally friendly.

The main advantages of ecofuel are significant savings, conservation of the environment and fossil resources. The only disadvantage of alternative sources is the significant investment required to initial stage. However, after 4-7 years, such systems fully pay for themselves and provide the owner with thermal energy without any financial investment on his part.

Solar heating

Solar systems for home heating can be used in two ways:

• transformation solar energy into electric which is used to function heating equipment;
• use of solar energy for heating the coolant liquid, which will circulate due to the operation of the pump or naturally and pass through heating radiators or convectors.

Important! Using a solar collector, you can make the simplest alternative home heating with your own hands. In addition to the collector, you will need a circulation pump and batteries.

The main disadvantage of solar systems is that in any region there are cloudy days when the system will be ineffective. Since there is no sunlight at night, solar systems are not suitable for 24/7 operation.

Options for heating a house using solar energy:

1. For 24/7 heating solar collector works in parallel with electric heaters. To control the temperature of the coolant, special sensors are used. When the heating temperature from the solar collector drops to the set minimum value, the heating elements are turned on.
2. Solar collector and inverter used in conjunction with a high-capacity battery. At night and on cloudy days, this battery will be the power source. The disadvantage of this option is that the battery life is five years, and the cost of purchasing new products is equivalent to five years of electricity bills.
3. Another option - solar batteries with inverter and controller, which are used in conjunction with any electric heaters.

Wind energy

One of the options for alternative heating of a cottage is the use of wind energy. You can find it on sale finished equipment for setting up the system. Its price is quite reasonable. However, since this equipment is intended for industrial use, the dimensions of the impeller are impressive. For example, a 4 kW wind generator may have an impeller measuring 10 m.

Important! Alternative methods of heating a home using wind generators are suitable for regions with constant windy weather. These are territories in the steppe area and settlements on the sea coast.

Wind turbines have the same operational problems as solar systems. One thing is that in the latter solar energy is used directly for heating, then when using wind power everything is much more complicated. In this case, the mechanical energy from the rotation of the windmill blades must be converted into electrical energy. Only after this can the house be heated. All this leads to a decrease in the efficiency of the heating system.

Thermal energy of the earth

To use geothermal energy, you will need special heat pumps. They convert the heat given off by groundwater, earth, and surrounding air. In this case, the temperature of the medium used must be above zero.

The principle of operation of the system is based on the collection of heat by heat pumps, its conversion and transfer to the heating circuit. The pump contains three closed circuits:

• the external one takes heat from the source (a brine solution or antifreeze circulates in this circuit);
• the internal circuit is filled with freon or other refrigerant;
• coolant circulates in the third heating circuit.

You can do this alternative heating of a private house with your own hands if you build simplest option heat pump. Depending on the type of heat source used and the type of coolant Different heat pumps are used:

• water-water;
• air-to-air;
• soil-water;
• water-air.

Important! Water-air and air-air pumps are used in the implementation of air heating Houses. Ground-to-water and water-to-water HPs are used in home heating systems with liquid coolants.

The most economically advantageous is a water-to-water pump. These systems are suitable for houses near which there are ice-free bodies of water. Heat intake pipelines are laid in them. From one meter of such a pipe 30 W of thermal energy is obtained. The length of the pipeline is determined by the area of ​​the heated house and the needs for thermal energy.

Pumps that use heat from the air cannot completely replace traditional heating systems in cold climates. Heat pumps, which draw heat from the ground, are considered expensive. These systems are best used in combination with water warm floors. The disadvantage of such HP is the significant length of the pipeline, which collects heat, expensive drilling and excavation work, as well as the need to develop a large-area geothermal field.

Biofuel boiler

A biofuel boiler uses agricultural waste (husks, peelings) and wood products (sawdust, wood chips). They are used to make dense granules called pellets. They are the ones that are burned in boilers. Pellets burn longer than wood and provide more heat. In addition to pellets, large briquettes are made from vegetable waste. Briquettes provide 2-4 times more heat.

Biogas is suitable for use in gas boilers. It is a product of rotting organic waste. To obtain biogas, you need to build a spacious tank for storing waste, and also provide a mixing installation. The process of decay and gas production occurs with the participation of bacteria and air. The waste material is collected and discharged through a special pipeline. In addition, you will need various devices for collecting gas, cleaning it and transporting it to the heating system.

Other alternative systems without gas

A hydrogen boiler is alternative source thermal energy, which is environmentally friendly. The operating principle is based on the reaction between oxygen and hydrogen molecules. As a result of this interaction, a huge amount of heat is released. However, to operate this type of heating, it is important to strictly follow safety precautions.

The main disadvantage of such a device is the high cost of the equipment used. The only way to save money is the option with self-production equipment. To operate, the system must be permanently connected to water and power. Also needed hydrogen torch, the boiler itself, catalysts and hydrogen generator. The heat produced by the chemical reaction is supplied to a heat exchanger. As a result of the operation of the installation, waste is generated - ordinary water.

What alternative systems can be used in an apartment building

Alternative heating of an apartment in apartment building is implemented using a solar battery with an inverter and a controller, which are connected in parallel to an outlet and are used in conjunction with electric heaters of any type. This scheme for saving energy in an apartment is easy to implement with your own hands.

You need to install a mechanical disk meter in your home, which will rewind the electricity in the opposite direction in clear weather, when the photocells will generate much more electricity than is spent on heating. Electronic meters are not suitable because they are not sensitive to the reverse direction of currents. When rewinding kilowatts in the opposite direction, significant savings are obtained.

In a desire to cause as little environmental damage as possible and reduce the consumption of non-renewable energy resources, many homeowners consider alternative heating as a source for heating their home in the winter. Currently, homeowners have access to a variety of alternative heating sources, which use solar energy, fuel pellets, wood briquettes, geothermal pumps, etc. in the process of generating heat.

Such systems are not only safe for environment, but also provide a number of advantages to home owners - they do not involve the use of products from the gas, oil or energy industries and reduce monthly heating costs. To find out which home heating alternative is the most acceptable and profitable, it is worth familiarizing yourself with the specifics of each heating system available on the modern market.

Geothermal system - using the heat of the Earth

Currently, alternative types of heating are represented by a variety of devices, among which there is a geothermal pump, which allows you to effectively generate heat in houses located in a temperate climate zone. According to the principle of operation, a geothermal system is similar to a standard house heating scheme - its operation requires the installation of radiators for coolant circulation, however, the key element of such a system is not a boiler, but a geothermal pump. Like a traditional gas boiler, this device is compact in size and will not take up much space in the house.

The efficiency of the pump is impressive - with one kilowatt of electricity consumed, it generates five kilowatts of heat.

The principle of operation of a geothermal system is that the heat exchanger is placed in the thickness of the earth or in the thickness of thermal waters, and the coolant circulating in it takes on ambient temperatures. Next, the heated coolant enters the heat pump and is then fed into the circuit, releasing heat to the room.

This alternative heating method is silent, safe and very effective. At the same time, the heat source for a geothermal heating system is an endless resource that is available at any time. Among the disadvantages of this method there are such nuances as the complexity of installation, the high cost of equipment, and the labor-intensive nature of excavation work, so making geothermal alternative heating sources with your own hands will be quite problematic and you will have to resort to the help of geodesy specialists.

Use of solar energy

Alternative solar heating systems can be active or passive. Passive solar heating relies on the use of special elements in a building's design to capture and store energy. Projects for the construction of such houses provide for the placement large windows on the south side of the facade, as well as the presence of surfaces inside the house to absorb and store solar energy. Such absorbing surfaces can be concrete walls and floors and other heat-saving materials in the structure of the house. They collect heat and store it for further use.

Alternative active heating systems for a private home require complex and expensive equipment - solar collectors, heat pumps, heat exchangers, reservoirs and elements for controlling energy harvesting, parabolic solar steam boiler, etc. Active systems in operation solar heating rely on the use of electricity to power certain elements.

Both heating systems are quite efficient and use 100% renewable solar energy as their heat source.

They can be used for heating and hot water supply to homes. Among the advantages of this type of heating, it is worth noting the absence of harmful emissions, environmental friendliness, stable operation, and reduction in monthly heating costs. Disadvantages are also present and lie in the high cost of the equipment and the complexity of its installation in the house.

Boilers using renewable energy sources

Unlike the systems listed above, which are characterized by a complex structure and high price, heating a private house with a wood-burning boiler can become an affordable and effective option for heating a home for a wide range of rational and economical owners. At present, wood heating country house is a good alternative to traditional gas boilers, the use of which implies the inevitable receipt of substantial gas bills every month. You can find out how to organize heating at home without gas here.

At the same time, home owners who have chosen this heating option can buy firewood for heating at an affordable price or prepare it themselves and achieve even more impressive savings. You can buy wood-burning boilers for home heating, the prices of which depend on the chosen model, in the store or on the manufacturer’s website. When choosing a boiler, you should pay attention to its specifications.

The following indicators are decisive:

It is worth noting that firewood is not the only type of fuel that boilers can operate on. In particular, alternative heating boilers can use sawdust, peat briquettes, pellets, and fuel pellets as burned fuel. Such materials are much cheaper than gas and liquid fuels, such as fuel oil. In addition, they can be produced in any country and do not require supply from other countries.

Boilers running on renewable wood fuel can be used as the main or additional heat sources in the house, and the owner can choose a model that optimally complements existing system heating and will make it more rational and economical.

Prospects

Competition among companies involved in the production and sale of alternative heating systems motivates manufacturers to set increasingly reasonable prices to attract customers. The authorities of states that do not have their own sources of oil and gas and depend on export supplies of fuel are also interested in using alternative heating. Therefore, it is likely that over the coming years, the installation of alternative heating systems in the home will become commonplace, and homeowners will be able to take advantage of the operation of an environmentally friendly system, which is qualitatively different from traditional heat sources.

Alternative energy sources for heating a private home

aqueo.ru » Heating » Alternative energy sources for heating a private home

The modern term "alternative" is borrowed from the Latin language (alternatus - other) for the need to choose from several possibilities or to designate each of these possibilities under consideration.

Energy sources for heating

Traditional way

Traditional methods of heating an apartment or private house require the installation of a heating system, which includes:

• a heat source that converts the energy of fuel combustion or the energy of network electricity into thermal energy;
• heat exchanger for transferring thermal energy from energy carrier to coolant, for subsequent distribution of heat among heat consumption points;
• a closed pipeline circuit through which the movement of coolant is naturally or forcefully stimulated;
• heating devices that distribute heat from the coolant into the surrounding environment of the room.

The figure below shows the structure of a heating system with a boiler as a heat source and heat consumption points in the form of heating radiators and heated floors.

The structure of a traditional heating system of a private house

Flaws

For most types of heating systems, the sources of thermal energy are heating boilers. They burn gas, liquid or solid fuel in order to use the heat of combustion of the fuel to heat the coolant (the so-called gas, liquid fuel and solid fuel boilers).

Another option for heating the coolant in the heat exchanger of a heating boiler is to use the energy of network electricity (electric heating boilers).

Each type of boiler and corresponding energy carrier has certain negative features that affect the efficiency of its use:

1. Gas fuel boilers are widespread due to the availability of gas.

Negative factors accompanying the use of gas for heating are:

• organizational and technical complexity of connecting to the gas main;
• the threat of fire or explosion if the rules for operating gas heating equipment are violated or if they are installed incorrectly with your own hands;
• rising prices for gas resources.

1. Electric boilers are the easiest to install and maintain yourself. Most significant shortcomings are:

• volatility of the equipment - when the power supply is turned off, the flow of heat into the heating system stops;
• high electricity tariffs.

1. Liquid fuel boilers as sources of thermal energy are quite difficult to operate. On the negative side, we note the following factors:

• high cost of liquid fuel, complexity of its delivery and safe storage;
• noise at work;
• unpleasant odors when burning fuel.

1. Solid fuel boilers using coal, peat, wood or pellets impress with their low cost of fuel resources and energy independence in operation, but they have their drawbacks:

• fuel loaded into the boiler firebox with your own hands quickly burns out;
• lack of automation of the fuel loading process;
• the need for constant visual monitoring of the boiler operation.

All of the heating systems discussed above have two common disadvantages:

• they operate on irreplaceable sources of thermal energy - the fuel is completely burned without the possibility of any recovery;
• the operation of equipment that burns natural resources or uses centrally supplied electricity is accompanied by constant payment for the volume of energy consumed and to service providers for its provision.

The figure below shows the delivery of liquefied gas for gas heating at home.

Delivery of liquefied gas to a private home

Points that require attention:

1. Such a convenient and familiar heating of a private home by burning non-renewable organic resources leads to a catastrophic decrease in natural fuel reserves at a cost from our own pockets! Naturally, prices for fossil fuels will constantly rise.
2. Fuel combustion is accompanied by emissions carbon dioxide and volatile toxic combustion products, resulting in the loss of tar and soot.
3. Each consumer of organic fuel is forced to equip additional premises:

• for fuel storage;
• for its combustion with the release of combustion products into the atmosphere.

Alternative heating concept

When considering alternative home heating options, you need to decide on the concept itself.

Alternative heat sources for a private home include two fundamentally: different types equipment:

1. Devices that work in addition to self-installed electrical or gas boiler. For some reason, a boiler running on gas or electricity does not provide full heat to the heating system of the entire building.

The main heating power is provided by the boiler, and during peak loads or off-season periods its operation is supported by alternative sources. In this case, alternative heating will be, for example, a home-made pellet boiler, or a unit that burns waste, and even infrared heaters.

1. Devices that completely replace a boiler running on gas, electricity or another traditional energy source. Their thermal power is enough to provide alternative heating for the house.

The most common alternative options for heating homes without burning gas and other fossil fuels are technologies that use energy natural resources- heat from the bowels of the earth, geysers, sunlight and climatic processes - wind, ocean tide.

House equipped with solar panels

Modern heating methods

The practical implementation of projects to use the energy of natural resources and phenomena as an alternative source of heat for heating a home most widely affects:

1. solar energy (solar thermal systems);
2. wind energy (wind power);
3. energy of the warm earth's interior (geothermal pumps).

Two options are noted practical application natural energy for the needs of alternative heating of a private home:

• transformation of the energy of a natural phenomenon into electrical energy, which will then be used for autonomous heating, that is, heating the house from its own internal source of electricity;
• direct heating of the working coolant of the heating system.

Solar thermal system

When installing solar heating systems with your own hands, both options for solar radiation are used:

1. Converting solar energy into electrical energy using solar panels.

Solar batteries are usually called a group of semiconductor photoelectronic converters combined in one common module to generate electricity. Several solar modules create a circuit to provide a private home with a certain amount of electricity.

The power of each solar module can range from 50 to 300 W. The picture below shows the principle of use solar panels for alternative autonomous heating of buildings.

House heating scheme using solar panels

The principle of operation of the solar system:

• from the solar module, the converted light flux enters the battery pack;
• batteries produce D.C., which is sent to the inverter;
• In the inverter, direct current is converted into alternating current, which is used to heat heating elements in the heating system.

Solar panels are only capable of generating electricity. They do not create, convert or accumulate thermal energy. They work equally effectively on a frosty day or at above-zero ambient temperatures, since the intensity of the incident solar flux is important to them.

1. Using solar collectors for direct water heating.

In private housing construction, do-it-yourself installation of solar collectors for alternative heating is more popular than installation of solar panels. Collectors convert solar luminous fluxes directly into thermal energy, bypassing the generation of electricity.

Do-it-yourself heating collectors have a wide variety of designs, which can be divided into two types:

• flat-plate collectors consisting of absorbers - elements that absorb solar rays (in the simplest case - metal plates or black sheets) connected to a pipeline system;
• pipe manifolds assembled from glass tubes, inside of which a steel absorber is inserted.

The figure below shows one of the options for making a solar collector with your own hands with copper tubes placed in the absorber for heating the coolant.

A coolant with a minimum crystallization threshold is pumped into the tubes. IN middle lane In Russia, a 60% aqueous solution of propylene glycol with a crystallization temperature of -390 C is recommended for use.

Solar collector made of copper tubes

Both types of collector systems are mounted on the sloping part of the roof of the house. The figure below shows the principle of heating a building using a collector.

The coolant heated in the solar collector (red line) enters the buffer tank, which acts as a heat accumulator and an automated system for maintaining temperature in the heating and hot water circuits.

If there is a lack of incoming heat on cloudy days, the water in the buffer tank is heated by another available heat source, for example, water from a gas boiler, which is the main heat source of the heating system.

Thanks to automation, the temperature in the heating system is constantly monitored. No arrival at night solar heat compensated by connecting a heating element to maintain a comfortable temperature level.

The operating principle of a solar heating system

Home wind power

The use of kinetic energy of air flows for the heating needs of a private house is carried out in two directions:

1. Converting kinetic wind energy into electrical energy by rotating the rotor of special wind generators.

The resulting electricity is accumulated in batteries and, as needed, through inverters (similar to solar heating technology) is used to heat water in the heating system. In calm weather, heating devices are connected to the general electrical network.

1. Converting the energy of the rotating windmill rotor into heat for direct heating of the coolant using vortex heat generators VTG.

The dominant method in private housing construction is do-it-yourself manufacturing and installation of devices consisting of a windmill, a generator and a battery to generate your own electricity. The design captivates with its simplicity and possibility self-assembly.

Wind generators differ from each other according to the following indicators:

• location of the axis of rotation – vertical or horizontal;
• number of propeller blades;
• propeller pitch.

The figure below shows a house equipped with wind generators with a horizontal axis of rotation.

Wind generators for power supply to a private home

Geothermal (heat) pumps

Devices that can use the geothermal energy of the earth's interior allow owners of private houses to significantly save on gas or other types of fuel when heating their homes. Thermal energy is extracted directly from the depths of the earth or from the bottom of a reservoir using a device called a heat pump.

The operating principle of a heat pump is similar to that of refrigeration unit using freon:

• when liquid freon passes through pipes at a considerable depth in a reservoir or in a drilled well, in which the temperature remains above zero even in winter, the freon begins to evaporate, turning into a gaseous state;
• the gaseous phase of freon rises to the top and enters the compressor, which strongly compresses it;
• when gas is compressed in a limited volume, it is heated to 80 degrees C;
• freon is cooled in the heat exchanger;
• in the throttle chamber, due to a decrease in temperature and pressure, freon again turns into liquid;
• the cycle repeats.

Heat pumps are energy-dependent units; however, the energy consumption for operating the device is disproportionately lower than what would be required for direct electrical heating of the coolant.

The temperature of the coolant in a heating system with geothermal devices does not exceed 50 degrees, which is not enough for radiator heating, but for “warm floors” it is quite enough.

Heat pumps are structurally different in the technology of heating freon before it passes into a gaseous state. Depending on the source of “low-level heat” there are:

• water installations for obtaining heat from surface reservoirs or underground groundwater;
• earthen, “taking away” heat from the ground;
• air.

Scheme of operation of a ground source heat pump

When classifying geothermal devices, the type of coolant in the heating system is also taken into account - water or air. Accordingly, devices receive the designations “soil - water”, “soil - air”, “water - water”, etc.

Video about heating

How to organize economical heating at home with your own hands, described in the video below.

The logic of switching to alternative heating is not only about saving money on buying gas or paying electricity bills.

Of course, prices for non-renewable energy resources are rising rapidly. But how can one not recall the words of D. Mendeleev, who said: “Burning oil is the same as heating a stove with banknotes”?

It is unreasonable to burn tons of coal or tens of cubic meters of wood to heat a modest room and at the same time cause irreparable damage to the cleanliness of the surrounding ecology.

In many countries, alternative types of heating and energy supply for individual residential buildings exceed in demand traditional ways heating The heating equipment market is filled with innovative alternative heating devices, the range of which is constantly expanding.

Alternative heat sources for home and apartment

Most of us have normal gas, coal or combined heating. Of course, there is also electric method space heating, but it is not very common due to the high cost of electricity. But what to do if the heat is suddenly turned off, there is a failure in the pipe, there is a blackout, etc.? Don't freeze in winter! Of course not, because in this case alternative heat sources come to the rescue. This is a mandatory attribute in an extreme or even catastrophic situation. Let's talk about everything in more detail.

Gas and electric heating

It is safe to say that today is an extremely turbulent and difficult time for many. Anything can happen to a gas line. For example, a major accident takes a long time to resolve, and if there are no alternative supply routes, then people will freeze. As for the electric option, firstly, it is expensive, and secondly, it is not very reliable. This is due to possible network overloads when connecting large quantity consumers. Nevertheless, gas and electricity are the main sources of heat today. All we can do is protect ourselves by installing emergency equipment. Sometimes you can make alternative heat sources with your own hands, we’ll talk about this a little later.

Solid and liquid fuel boilers

These are perhaps the two most common solutions today. This is due to the high availability of equipment. Of course it's labor intensive installation work makes itself felt, but here's the cost solid fuel(coal, firewood, etc.) quite reasonable. But you need to think about such a heat source in advance and install it together with gas equipment. Certainly, water system can be carried out in parallel with the electric convector, so, in fact, it’s better to do so. As for liquid boilers, this is good decision, but in recent years the popularity of this heating method has been decreasing. This is due to increased fuel costs. The latter is vegetable and machine oil, and waste oil is also suitable. If you work in a production facility where dozens or even hundreds of such fuel are spilled every day, then it’s time to think about this issue. Such alternative heat sources for the home are extremely relevant, especially if there are oil reserves. Let's move on.

Alternative heat sources, made by yourself - it's easy

Sometimes we ourselves can make something for heating. The simplest option is a potbelly stove. Most often, a barrel or large-diameter steel pipe is used as a body. Two holes are made in the body, one larger is the firebox, the second smaller is the ash pan. It is advisable to make doors. Slightly below the level of the firebox door, it is necessary to make brackets on which the grate will be placed. The latter can be made from conventional reinforcement by welding. If you are making a potbelly stove from a pipe, then you need to weld the upper and lower parts. But don't forget that you need a chimney. To do this, a small hole is cut from the top and a pipe is inserted into it. In fact, such alternative heat sources, made with your own hands, are quite capable of heating a large room during the cold season. Coal or wood is used as fuel. Do not forget that you need to connect to the chimney.

Long burning stoves

This heating option has become more common over the past few years. This is due not only to good advertising, but also to the high efficiency of the method. The bottom line is that there are two stages of fuel combustion. In the first, smoldering and release of wood gas occurs, and in the second, combustion of the latter occurs. As a result, we have quite efficient, but at the same time economical heating. But it is necessary to carefully monitor the moisture content of the fuel. If this indicator is higher than normal, then the amount of heat released will not be so large, sometimes such fuel will not even smolder. Therefore, more attention needs to be paid to storage. It is better to give preference to a garage or any other covered, dry room. Leaders in furnace production long burning“Breneran” (Canada) and “Buleryan” are considered to have an air or water circuit. In principle, such alternative heat sources for an apartment should not be ignored. Moreover, sometimes this is the only available solution.

Heat pumps - alternative heat sources for a private home

Many people have never even heard of this method of heating a room. But today, if we consider alternative heat sources, this is one of best options. This is due not only to high efficiency, but also to safety. The idea is that heat collected from soil or water is transferred to the heating system. IN summer time Most often the reverse principle is used (cooling the building). As you can see, one heat pump can solve several problems. In winter it is a heating system, in summer it is air conditioning. As for efficiency, heating costs will be approximately 10% lower than gas. But often the problem lies in the fact that not everyone can afford heat pumps, because they are expensive equipment that requires precise professional installation. And this system is too dependent on electricity, so it doesn’t make much sense when there are problems with electricity.

Install TEK or fireplace

Hydrodynamic installation (heating), also known as TEK, is new source alternative room heating. The design of the installation includes an expansion tank (hydraulic accumulator), a pump and an electric pump. The principle of operation is based on the release of energy from two streams of water that collide with each other when entering the tank. Often it is simply connected to the heating system of an apartment or house and does not require the installation of additional equipment such as a circulation pump, mechanical filter, etc.

As for such a solution as installing a fireplace, this is not available to everyone. But if you live on the top floor or the building has a chimney, then you will not have any problems. Of course, this is quite expensive and requires a lot of space in the room. But in return you will get excellent heating. In principle, these are the most popular alternative heat sources for dachas, where there is a lot of space and it is possible to make a chimney yourself. The main thing is to properly design the air heating system so that air flows through the entire room.

Basic information about solar systems

Solar systems, despite their complexity, are quite popular. But if their use in apartments is difficult, then for a dacha or country house this is just what you need. This heat source consists of a solar collector (vacuum). A collector is installed on the roof, where it collects solar energy. When the rays hit its surface, the room heats up. It is noteworthy that the system works even with sub-zero temperature or cloudy weather. But do not forget that it is extremely important to monitor the condition of the plates, clean them of snow, leaves, etc. Since thermal energy is ultimately supplied to the heat exchanger, it is used for the heating system and heating water for household needs. But in places where there is almost never sun, such systems are impractical to install.

So what to choose

We have considered the main part of alternative heat sources. As you can see, there are quite a lot of them. But what you install is up to you. Thus, solar systems are preferable in the southern and central regions, and in the northern regions it is practically useless to install them. A fireplace is suitable for a country house, but it is better to install a slow combustion stove in an apartment. The best alternative heat sources for a garage are potbelly stoves, since here you can burn waste oil without worrying about a specific smell.

Conclusion

That, in principle, is all that can be said on this topic. The choice is very large; you need to be guided not only by your own preferences, but also soberly assess your financial capabilities, as well as the feasibility of this or that choice. If you come to your dacha a couple of times a year, then it hardly makes sense to install a solar system there; it’s the same as installing a potbelly stove in a European-quality renovated apartment. Of course, the decision is yours, but make it wisely and think about safety first, as well as staying warm during difficult times.

Heating without gas: 7 alternative heat sources for a private home

Traditionally, a private house is heated with a gas boiler. But what to do if the site is not connected to the gas main? Or there are interruptions in the gas supply and you want to have insurance in this case? Or you just want to reduce your dependence on gas and the state.

In this case, it is necessary to consider the option of alternative heating of the house. And then we will look at what can be used. Which devices will serve as a full replacement for a gas boiler and provide heating without gas, and which can only be used as a supplement.

What is an alternative heat source

Since traditionally the house is heated with a gas boiler, by alternative home heating we mean any heating device that does not run on gas.

When is it relevant?

1. You are unable to connect to the gas network or it is too expensive;
2. You want to reduce your dependence on gas and have insurance in case of severe frosts or interruptions in its supply;
3. To save on heating costs. Combining and properly managing heat sources will reduce your heating costs.

Types of Alternative Energy Sources

Conventionally, alternative heat sources are divided into two types:

1. Which work in addition to the boiler. For various reasons, they are not able to fully provide the building with heat. The main heating power is provided by the gas boiler, and other sources support its operation during peak loads or off-season.
2. Which replace a gas boiler. These are the heat sources that are capable of producing sufficient heating power to warm the building.

Let's consider what devices can be used in each case.

Heat pump

A heat pump is one of the most economical heating methods. It runs on electricity and converts natural energy into heat to heat your home. Depending on the type, the pump can be the only source of heat in the house and fully provide heating without gas, or it can work in addition to the boiler.

• Ground heat pumps are a complete alternative to a gas boiler. They work equally efficiently regardless of the outside temperature and completely provide the building with heat. Their disadvantages: high initial cost, payback period of more than 10 years and the required availability of a large plot of land to bury a ground collector.
• Air source heat pumps are cheaper and easier to install. They can also replace gas heating, but at zero degrees and sub-zero temperatures their efficiency drops significantly. Heating becomes economically unprofitable. Therefore, it is optimal to use “air vents” in conjunction with a boiler: in spring and autumn, when it is warm outside, the pump mainly works, and in winter and when it is cold, a gas boiler is switched on.

See also the operating principle of a heat pump.

In addition to the heat pump, you can connect a two-tariff electricity meter, which will reduce heating costs by another 30-50%.

Solid fuel boilers

Solid fuel and pellet boilers are one of the most available ways heating a private house without gas. They are cheaper than a heat pump and are able to completely provide the building with heat, regardless of the time of day and street temperature.

But when choosing and installing solid fuel boilers, you need to consider:

• You need to constantly monitor the combustion and add firewood 1-2 times a day. Of course, this is not so difficult, but in comparison with gas boilers it causes inconvenience. In pellet boilers this is easier, since they provide automatic supply of pellets into the firebox from the hopper.
• Not all regions have developed woodworking and it is possible good firewood will have to be transported from afar. So make sure you have access to at least 2-3 firewood sellers.
• You need to buy firewood one year in advance heating season. A year is the required period for the firewood to dry out and accumulate energy value. Initial low humidity only for fuel briquettes.
• You become dependent on firewood instead of gas.
• At certain volumes of consumption, heating with wood is not cheaper than gas.
• Need storage space. If firewood is stored incorrectly, it will get wet and lose its energy potential. See the article on how to store firewood.
• From time to time you will have to clean the chimney and the inside of the boiler from soot.

Solar collectors

Solar collectors - good way reduce gas consumption and complement the operation of a gas boiler.

It will not be possible to fully heat the house using collectors. They definitely need a second (main) heat source in combination, because in winter the daylight hours are shorter and the solar intensity is much weaker than in summer.

The collectors are ideal for heating water for domestic hot water supply in summer, spring and autumn. And in winter they can only be used to support heating.

Fireplace with water circuit

This fireplace is a combination of a traditional fireplace and a solid fuel boiler: it is installed indoors and connected to common system heating. There is a container of water installed inside the fireplace, which heats up when the wood burns. Due to this, you not only heat the air in the room, but also heat the water in the heating system, which then goes to the radiators, heated floor or storage tank.

Theoretically, a fireplace with a water circuit can be an alternative to gas heating. But since it does not have automatic fuel supply and new firewood needs to be added every 2-4 hours, you shouldn’t count on it too much. If you don't add wood in time, the fire will go out and the house will cool down.

Therefore, such a fireplace should be considered as an addition to the main heat source.

Conventional air fireplaces

Conventional fireplaces are cheaper and easier to install. It does not require connecting a pipe in advance, installing a storage tank or providing thermal protection. It is enough just to allocate a place and build a chimney.

The fireplace only heats the air around it. And to increase its efficiency, you can run air channels from the fireplace to each room. Due to this, the fireplace will heat not only the room in which it is installed, but also other rooms where air ducts are installed.

The difficulties with a regular fireplace are the same: it will not replace a gas boiler, and you will also have to regularly add firewood and monitor the combustion. This is an excellent additional and alternative source of heat, but nothing more.

Pellet fireplace

A pellet fireplace also only heats the air around it. But he has two important advantages:

• It is not necessary to have a chimney in advance. For such a fireplace, you need a small diameter pipe, which is led into the wall, and not through all the floors of the building.
• There is automatic fuel supply. That is, you do not need to constantly monitor combustion. It is enough just to maintain a supply of fuel pellets in the bunker. Therefore, a pellet fireplace is quite suitable as an alternative heating without gas. But from a practical point of view, this is inconvenient: the fireplace is locally effective and only heats the room in which it is installed. It is impossible to use heat throughout the entire house.

Disadvantages:

• You need access to high-quality pellets that will not clog the burner with soot and burn well.

Air conditioners

Air conditioning is the most affordable and simplest alternative source of home heating. You can install one powerful one on the entire floor or one in each room.

Most best option using an air conditioner - in late spring or early autumn, when it is not too cold outside and you don’t have to start the gas boiler yet. This will reduce gas consumption due to electricity and not exceed the monthly gas consumption rate.

Important points:

• The boiler and air conditioner must be linked to each other to work as a pair. That is, the boiler must see that the air conditioner is working and not start working while the room is warm. A wall thermostat is indispensable here.
• Heating with electricity is not cheaper than gas. Therefore, you should not completely switch to heating with air conditioners.
• Not all air conditioners can be used in freezing temperatures.

To become less dependent on gas, you need to work on the energy efficiency of your building. Read about possible hidden heat leaks in a private home.

Personal experience

I use four heat sources to heat my house: a gas boiler (main), a fireplace with a water circuit, six flat-plate solar collectors and an inverter air conditioner.

Why is this necessary?

1. Have a second (backup) heat source if the gas boiler fails or its power becomes insufficient (severe frosts).
2. Save on heating. Using different heat sources, you can control the monthly and annual gas consumption rates so as not to switch to a more expensive tariff.

Some statistics

Average consumption gas in January 2016 - 12 cubic meters per day. With a heated area of ​​200m2 and an additional basement.

Fluctuations in consumption by day during the month are associated with different street temperatures and the presence of the sun: on sunny days the collectors operate and gas consumption decreases.

conclusions

Heating without gas is possible. Some heat sources serve as a complete replacement for a gas boiler, while others can only be used as a supplement. For convenience, we will combine everything into a table.
