Having decided to heat the home with wood and coal, the homeowner does not want to work as a fireman and run to the boiler room every 3-4 hours. This is where the demand for solid fuel boilers arises long burning, which can work on one bookmark for 6-8 hours or more. How to choose the right heating unit, read our publication.

Operating principle of long-lasting heaters

Many Russian, Belarusian and even Polish companies have caught on to the trend and have launched the production of long-burning domestic heat generators operating on solid fuel. Moreover, half of them give the buyer incorrect information, adding the characteristic “long-term combustion” to the name of an inexpensive wood-burning boiler that works for a maximum of 6 hours from one tab.

Operation of a conventional heater requires constant preparation of firewood

To avoid getting scammed attractive price, and to choose a thermal unit with real indicators, you should understand what the duration of its operation depends on. There are 3 factors at play here:

1. Firebox capacity. The more wood and coal that enters the heat generator chamber, the longer they will burn.
2. Fuel combustion efficiency (COP). An economical boiler with high efficiency will emit less thermal energy into the chimney, and the heating system will receive more. Accordingly, the consumption of firewood will decrease.
3. Availability of automation and forced air supply, turned on only when necessary.

Reference. Despite the assurances of manufacturers, the efficiency of the vast majority of solid fuel heaters of classical design is 75-77%. The real indicator of pyrolysis and pellet units is not much higher - 80-82%.

The operating principle of the heating system is based on a large supply of fuel and its complete combustion within 8-12 hours. A long-burning solid fuel boiler should not operate in the notorious slow-smoldering mode, as advertising assures us. The reasons are as follows:

• smoldering firewood produces little heat to heat a private home;
• the efficiency of heat transfer from the combustion chamber to the water jacket decreases, as a result, the efficiency drops to the level of an air stove - potbelly stove.

Hence the conclusion: from the user’s point of view, the best long-burning boiler should have a decent-sized firebox and modern automation, other factors do not have much influence. We will clarify the capacity of the fuel chamber further.

Fan and electronic boiler control unit

Review of long-burning thermal units

Practice and reviews from homeowners on forums show that the following types of boilers should be included in this category:

Note. For efficient use of fuel, all of the listed varieties must be equipped with a turbocharger - a fan or a smoke exhauster. Its launch and performance are controlled by an electronic unit that reads temperature sensors.

The advantage of a homemade boiler is its relatively low cost and the ability to take into account your wishes. The wizard will help you choose a heater design and make a fuel chamber required sizes. If you know electric welding, you can make the unit yourself according to the drawings provided.

How to choose a classic boiler

A traditional direct combustion heat generator equipped with a blower fan is a completely affordable and reliable option for the average owner of a private home. The unit operates according to a simple scheme:

Note. Wood heaters, equipped with a mechanical draft regulator instead of electronics, are not very economical. The fact is that the chain drive does not close the vent tightly and air penetrates into the chamber, causing the wood to burn slowly.

Now let's talk about how to compare the operating time data given in the product data sheet with the actual size of the camera. If the volume of the firebox is less than 50 liters with a power of up to 30 kW, then you have a regular boiler that requires loading every 4 hours.

Classic and long-burning pyrolysis boilers have a firebox of 100 liters or more with a similar power. This is a sure sign that from 1 load of wood the heat generator will work for about 8 hours, coal - 12-15 hours.

In this design, flue gases make 4 passes in the heat exchanger

When choosing, pay attention to the design of the heat exchanger. It is better to buy a boiler installation with a developed structure of smoke pipes or channels, where hot gases make 2-4 revolutions. Giving as much as possible thermal energy before exiting, combustion products increase the operating time from 1 load.

Top combustion units

These boilers are record holders in terms of firebox volume and combustion duration. The well-known Lithuanian-made Stropuva thermal unit with a power of 20 kW has a chamber of as much as 260 liters. Accordingly, the instructions for its operation provide correct information: when loaded with firewood, “Stropuva” burns for 15-24 hours, and with coal – up to 3 days.

The operating principle of the heat generator is as follows:

1. The cylindrical combustion chamber is filled with fuel, pressed down from above by a pipe with a load. After ignition, the door closes and the fan starts, as described in the previous section.
2. Air is forced into the chamber through a pipe from above, so the combustion zone is also located in the upper layer of fuel.
3. As the mass of firewood (or coal) burns down, it sags, and the pipe with the load goes down next until it reaches the grate. The automation operation algorithm is the same as in a traditional heater.

Note. These boilers repeat the principle of operation of the universal one. The design is distinguished by a water jacket and the presence of automation.

You need to understand that top combustion is not the decisive factor that increases the operating time of the heat generator. The main role here is played by a decent volume of firebox and automation. But judging by the reviews of real homeowners, boilers such as Stropuva, ​​Swag and the like have significant disadvantages:

• due to the design of the load in the form of a cross, part of the fine fuel sticks from the inside to the walls of the combustion chamber;
• until the first load of coal or wood burns completely, a new portion cannot be added (the entire mass of fuel will ignite, and not the top layer);
• Due to the size and depth of the chamber, it is problematic to lay a small portion of firewood in order to quickly heat the home from dampness.

An additional disadvantage of heaters is the reduced threshold for the maximum operating pressure of the coolant. If in classic TT boilers the limit is 3 Bar, then in Stropuv it is only 2 Bar.

Automated pellet heat generators

A pellet boiler is the ideal version of a long-burning unit, but it is also the most expensive. It is highly efficient and is loaded once a week. The heater consists of two main blocks - a boiler body with a water jacket and a pellet burner with a fuel hopper and an electronic control unit.

The burner, controlled automatically, ignites and goes out independently at the command of the temperature sensor. Some products from German and other European brands are capable of changing the intensity of the flame (perform modulation). Therefore, from the point of view of safety, efficiency and longevity, a pellet boiler is the best option of all existing ones.

Note. There are coal boilers of a similar design on sale, but they are demanding in terms of quality and fuel fraction. Watch the video to see how pellets are burned automatically:

We have already described above how to choose the right heating unit according to the size of the firebox. Point two: pellet automated installations are best suited for the role of a long-burning boiler, and top-combustion heaters take third place due to design and operational shortcomings.

To make a successful purchase, be sure to consider the following factors:

If you plan to heat with coal, then when choosing, pay attention to the grate - it should be all-metal. Hot coal sticks tightly to water-filled grates and is quite difficult to clean. The expert will give you a few more recommendations in his video:

Conclusion

When deciding to buy and install a TT boiler with long-term burning of wood or coal, consider the cost factor. The price of a quality product is much higher than 250-300 USD. That is, what they ask for for steel units of unknown origin. A good homemade boiler with a power of up to 30 kW will cost about 550 USD. e., and the factory one - at least 900 USD. e.

Solid fuel boilers are an alternative way to heat private houses. Electric models consume a lot of electricity, so the effectiveness of their use (especially over large areas) is very questionable. Gas boilers in this regard, they are more justified, but they require the supply of the appropriate type of fuel to the house, which is not always possible. It is in such cases that it is very difficult to overestimate the benefits of stoves, the combustible material for which is firewood, coal and other solid elements.

The current market realities are such that potential consumers are presented with hundreds, if not thousands, of models of heating boilers for every taste: long-burning and pellet, classic and pyrolysis. It is quite natural that making a good choice in such a situation is very, very difficult. To simplify the situation a little, we have prepared for you a rating of the 18 best solid fuel heating boilers in six different categories.

The best long-burning solid fuel boilers

The advantage of long-term heating boilers over others is clear from the name: the duration of solid fuel burning in them when the furnace is fully loaded is two to three days, and in other cases (depending on the type of fuel) it reaches five or even twelve days. At the same time, a volume of thermal energy sufficient to heat the entire provided area is released on an ongoing basis. They are economical, but have low efficiency and cause a lot of trouble to maintain.

3 NMK Magnum KDG 20 TE

Profitable price
Country Russia
Average price: 48,000 rub.
Rating (2019): 4.8

A typical representative of long-burning boilers from Russian manufacturer, which was created specifically for the climatic conditions of our vast country. Unlike many other contenders (according to manufacturers’ recommendations), it uses exclusively coal for heating, which burns out within five days with an efficiency of around 75-80 percent. This is not much, but when heating with other fuels, for example, wood, the situation looks much more sad. Users' feelings from the operation of this boiler are generally positive: the design is serviceable, it is unpretentious in maintenance, and in terms of power in general it is the “golden mean”. I am very pleased with the existing system for regulating fuel combustion, albeit primitive.

Advantages:

• a domestically produced product, which explains the favorable price;
• good workmanship;
• availability of a system heating regulation(the connection between the adjusting links is made by a chain).

Flaws:

• the need to observe a strictly defined position of the air damper (with a gap of five millimeters) for proper operation boiler

2 Stropuva Mini S8

The optimum ratio of price and quality. User selection
Country: Lithuania
Average price: 56,500 rub.
Rating (2019): 4.8

Lithuanian heating boiler, highly rated by users. In fact, the manufacturing company Stropuva continues and naturally reaps the benefits of the system built during the Soviet Union. The Mini S8 boiler is compact, made in the form of a “barrel”, but it is very heavy to move, which causes some problems with installation. Its efficiency is associated, first of all, with its type - long burning of one load of coal can provide heat for two to five days. There are also no complaints about the quality - everything is done reliably, neatly (which is not so important in boilers) and evokes some semblance of true admiration. But there is still one miscalculation - the shagreen lining is practically impossible to remove carbon deposits, which most often form above the firebox door.

Advantages:

• very high quality execution;
• economical heating of premises - one stack of firewood is enough for 12-20 hours of combustion; coal – up to five days;
• good balance between price and quality;
• the ability to connect additional circuits, heating elements, and other systems.

Flaws:

• beautiful, but impractical shagreen covering;
• difficulty in moving due to the large weight of the “mini-model”.

To complete the picture and clarify what pros and cons this or that type of solid fuel boiler has, let us turn to the comparison table:

1 Buderus Logano G221-25

Best quality
Country: Germany
Average price: RUB 154,580.
Rating (2019): 4.9

German boilers from Buderus are the standard of quality and efficiency for heating spacious rooms. Despite their Eastern European production, they can easily withstand the difficult conditions of the harsh Russian winter, have a fairly high level of efficiency (85 percent), and also do not require a large amount of fuel. If the circulation pressure of the coolant is not enough, you can easily “hook up” a pump to the Buderus Logano G221-25, which is what savvy users resort to. Heating occurs very quickly, and cleaning the firebox does not cause any difficulties. Thus, 20-kilowatt models are capable of heating a room of up to 200 square meters. And judge for yourself what a 25-kilowatt boiler is capable of.

Advantages:

• voluminous firebox – accommodates logs up to 68 centimeters long;
• nice design;
• excellent workmanship and impeccable design reliability;
• high energy efficiency;
• unpretentious in maintenance and easy to install.

Flaws:

• high price.

The best inexpensive solid fuel classic boilers

Classic heating boilers are by no means rare devices in use. They are successfully used by people for heating private houses or for installation in houses on summer cottage. By the way, inexpensive models are ideal for the second rather than the first option. They are by no means bad, but their characteristics very often turn out to be overestimated, which leads users to disappointment after the first attempts to use them.

3 EVAN WARMOS TT-18

High power rating
Country Russia
Average price: 32850 rub.
Rating (2019): 4.4

Solid fuel boiler of Russian origin. Not bad to become a source of heat for country house, but is doubtful for use in private premises. Its whole problem lies in its overstated characteristics - the rated power of 18 kilowatts is designed to heat areas up to 120 square meters, but the effect of heat transfer is practically not felt. The real and most effective heating threshold is no more than 60 square meters. Solid fuel, at optimal regulation dampers, burns out in 60-90 minutes, after which the boiler quickly cools down and, if this moment is missed, requires re-ignition. And you can’t forget about the functions of a stoker either. The result is logical: the model is quite capricious, but if desired, you can always find a compromise that suits both parties.

Advantages:

• very simple installation of the boiler;
• acceptable quality of the case;
• capable of working on wood, coal and peat.

Flaws:

• inflated data on heated areas;
• the need to select the optimal position of the damper to prevent excessive fuel consumption or interference with normal combustion.

2 ZOTA Dymok-M AOTV-12M

Optimal balance of characteristics
Country Russia
Average price: RUB 18,870.
Rating (2019): 4.6

An ideal model for installation in a summer cottage. Small, but with decent power potential; unprepossessing, but it makes up for it with its original functionality. 12 kilowatts of thermal power released during complete combustion of combustible material is enough to heat 80 square meters of area. Even 70 percent efficiency does not spoil the overall impression of the work. This version of the stove is combined, so it can also use an electric element (heating element) for heating. At the top of the body there is a hob - a pleasant addition to the main function and acceptable characteristics.

Advantages:

• Availability hob as a nice addition;
• efficient heating of the area declared by the manufacturers;
• possibility of connecting a thermal electric heater;
• The coolant is heated to a temperature of 95 degrees Celsius.

Flaws:

• mediocre appearance;
• a little overpriced.

1 Lemax Forward-16

Best price
Country Russia
Average price: 16,500 rub.
Rating (2019): 4.8

16 kilowatts of power of the Lemax Forward-16 boiler is enough to heat administrative and domestic premises, private residential buildings and even cottages, through independent or forced (with the installation of a pump) circulation of the coolant through the heating water system. This is one of the most successful examples of small but productive installations with an uncharacteristically high (about 75-80 percent) level of efficiency. The simple design contains a solution to many operational problems. From the point of view of a technologist, such measures as, for example, “padding” the heat exchanger with channels to increase the ultimate tensile strength look redundant, but are justified from the point of view of durability of use. Such a boiler can last a good seven to nine years, provided that all correct operation measures are followed without exception.

Advantages:

• Availability additional elements, which have a positive effect on the durability of the installation;
• optimal cost with acceptable quality;
• a fairly high (atypical) level of efficiency;
• the ability to connect a pump to increase the coolant circulation rate;
• the possibility of converting the boiler to work with gas (carried out by installing a gas burner device).

Flaws:

Boilers: classic solid fuel boilers of premium class

More expensive classic boilers are installations of a completely different level. Unlike their budget “brothers”, they have a higher percentage of efficiency, power, and overall reliability indicators (not always, but as a rule). The disadvantages of inexpensive classics, expressed in the deliberate overestimation of characteristics, are absent here, however, the typical disadvantages of classical systems are fully manifested.

3 Kentatsu ELEGANT-03

Optimal cost
Country: Japan
Average price: 35990 rub.
Rating (2019): 4.8

Kentatsu ELEGANT-03 is a modified model of a heating boiler, which took into account all the nuances and errors of previous installations. It is reliably known that they, in turn, did not have efficient cooling and allowed the boiler to overheat. In this version, this is a water grate cooler, and, as practice shows, it copes with the assigned task flawlessly. On the front wall of the cast iron body there is a thermometer showing the real temperature of the coolant water. A controversial step towards ensuring ergonomics was the division of the boiler into sections. On the one hand, the usable area inside the model has increased, but on the other, this has a negative impact on the service conditions.

Advantages:

• the model took into account the mistakes of the past, including with active cooling;
• Availability of equipment for self-service;
• low price;
• high quality and durability of the cast iron body;
• presence of a thermometer on the front wall.

Flaws:

• dividing the boiler into sections complicates the process of repair and maintenance in the event of a breakdown.

The best efficiency indicator (90.2%). High boiler power (39 kW)
Country: Slovakia
Average price: 109,500 rub.
Rating (2019): 5.0

Protherm Beaver 50 DLO is a real monster among the elite, a Slovak-made product that will definitely appeal to anyone who wants to have a high-performance heating boiler.

The Slovaks did not come up with anything new to preserve useful thermal energy. Based on known physical laws, facts and practice, they simply stuffed thermal insulating glass wool under the cast-iron body, thereby reducing heat losses. As a result of this simple step, efficiency skyrocketed to a crazy 90 percent. By updating the standard shape of the heat sinks, they were able to increase the volume of the combustion chamber. Thus, with one load you can achieve a completely comfortable temperature in a room of up to 350 square meters. This is largely due to the rated power of 39 kilowatts.

Advantages:

• high technical characteristics;
• adequate build quality;
• large heated area;
• low heat losses due to the presence of insulating material;
• presence of an air regulator;
• availability of maintenance tools in the kit.

Flaws:

• not detected.

The best solid fuel pyrolysis boilers

The action of pyrolysis, or gas generator, boilers is based on the combustion of wood gas released from smoldering firewood under the influence of temperature. When passing through the nozzle, the gas burns out, which contributes to the formation of a small amount of ash and soot. The efficiency of such boilers reaches 85 percent. The burning time of one load ranges from 5 to 12 hours. The disadvantages include the high price and special requirements for fuel - only dry wood is needed for heating.

3 Wirbel BIO-TEC 35

High level of efficiency (91%)
Country: Austria
Average price: RUB 370,216.
Rating (2019): 4.8

An Austrian boiler capable of maintaining a comfortable temperature throughout the day. It all depends on the selected power: in the nominal combustion mode, firewood and briquettes last no more than four hours. As the indicator decreases, the rate of complete combustion of the bookmark decreases. According to experts, an important difference between this model and domestic ones is the occurrence of a real pyrolysis process, as opposed to ordinary afterburning. Perhaps the only drawback of the boiler is the need for a constant connection with CAS - a specialized heat storage tank. The supplied control panel is responsible for the operation of the systems.

Advantages:

• presence of a control panel – complete automation of processes;
• after pyrolysis, the process of afterburning the exhaust gases occurs - complete exhaustion of fuel;
• high rated power.

Flaws:

• failure of the control panel deprives the user of the ability to manipulate processes;
• very high cost.

2 Bourgeois-K STANDARD-20

Affordable price
Country Russia
Average price: 55,470 rub.
Rating (2019): 4.8

The heating power of the Bourgeois-K series boilers has been repeatedly questioned - they say, a value of 20 kilowatts means absolutely nothing, since it does not heat the declared area of ​​200 square meters. Some users take the side of the manufacturers, while others claim inability. Nevertheless, the endless debate has created a good buzz around the model range, so the technology does not experience a shortage of attention. The burning time of one bookmark in it is about ten hours. In terms of price, this boiler is noticeably inferior to “foreign” models, which is its main and irrefutable advantage.

Advantages:

• the cost is lower than that of competitors;
• high thermal power and corresponding heating capacity;
• burning duration of the bookmark;
• low consumption of combustible material.

Flaws:

• there is a huge stir around the possible discrepancy between the characteristics of the declared information.

1 Wattek PYROTEK 36

Best rated thermal power (36 kW)
Country: Czech Republic
Average price: 171,900 rub.
Rating (2019): 4.9

Pyrolysis boiler of a serious European level, created in accordance with all current quality standards. Czech manufacturers decided to release a line of installations with automatic control, which at the same time made life easier and more difficult for themselves and their users. The fact is that “automation” is a delicate thing, and in some particularly unfavorable cases (due to accidents) it can easily fail. Repairing and setting up a control system on a boiler of this level is expensive, which often causes bewilderment and an angry reaction from people. Perhaps this is the only significant drawback of the system, because in other components it is almost perfect.

Advantages:

• the presence of an automatic control system for temperature and operating parameters;
• presence of emergency, boiler and boiler sensors;
• burning of wood stock is 12 hours, briquettes – 15-17 hours;
• high quality assembly materials;
• expanded complete base.

Flaws:

• adjustment and repair of an automatic control system, in case of failure, will cost the consumer a pretty penny.

The best solid fuel pellet boilers

Pellet boilers are large installations equipped with bunkers for granulated wood waste. The sizes of such granules range from 5 to 70 millimeters in length and from 6 to 10 millimeters in thickness. This is the longest-lasting method of heating a room. The duration of heating directly depends on the volume of the adjacent bunker, and can be 2-12 days. The main disadvantage of such boilers is scarce fuel. Granulated pellets are not sold everywhere, so there is a high probability of equipment downtime.

3 ZOTA Pellet 100A

Country Russia
Average price: 379,000 rub.
Rating (2019): 4.9

One such boiler is more than enough to heat an entire building, where there is a water heating system with a pre-installed pump for forced circulation. Manipulation of all aspects of the system is reduced to the electronic control panel. This system is truly indestructible - unless, of course, the user has the opposite goal. The rated power of the boiler reaches 100 kilowatts, but it can be reduced by regulating the air supply. The supply of pellets to the firebox is regulated in the same way. The only and most significant disadvantage system is an overweight design. 829 kilograms - that’s how much this unit weighs, which is not so easy to move even within the scope of the delivery task, not to mention the final installation.

Advantages:

• the price corresponds to the stated parameters;
• fuel is supplied to the combustion chamber by a screw mechanism;
• electronic control system controls all aspects functionality installations;
• high rated power.

Flaws:

• very heavy weight of the structure.

Average price: 554,000 rub.
Rating (2019): 4.9

Almost a complete analogy of the lower model, ACV (ATsV) TKAN 100 is one of the best pellet boilers on the world market. A screw feed mechanism, the presence of an electronic control system, a rated power of 100 kilowatts - all this is not new. The main difference between the two models lies in the price and weight parameters - the ACV weighs only 595 kilograms (significantly less than its opponent), but costs one and a half times more. However, based on the words of experts and those rare users who dealt with this boiler (mainly at large enterprises), we can conclude that its quality parameters are very high.

Advantages:

• not the heaviest weight of the structure;
• high level of efficiency (90%) and rated power;

Rating (2019): 5.0

Although not large, the high-performance model of the PELLUX COMPACT pellet boiler can boast a high efficiency value - as much as 92 percent at the optimal operating level. All this and much more is the result of the vigorous activity of the Swedish company NIBE, specializing in the production of solid fuel boilers. This efficiency value is achieved by the installed burner, which has a positive effect on reducing the consumption of granulated pellets while increasing the release of thermal power. Another clear advantage is the presence of a replacement mesh in the combustion chamber, which allows you to turn a pellet boiler into a pyrolysis boiler by replacing the pellets with dry logs.

Advantages:

• economical burner, which reduced fuel consumption and increased thermal power;
• availability of automated electronic control;
• the ability, if necessary, to switch to another type of fuel - from pellets to firewood and vice versa;
• high level of efficiency;
• high build quality.

Flaws:

• no serious deficiencies were found.

The service life is ensured by a “water tower” surrounding it on all sides, preventing overheating and burnout of the metal.

The functionality of the model is enhanced by some design features provided by the manufacturer. It is possible to equip the boiler with a gas burner - it is installed instead of the ash pan. There is also a hole for mounting a heating element on the side surface, which allows you to use electricity as a backup fuel. Despite the low cost, positive reviews prevail about the model.

Advantages:

• two circuits;
• the presence of a hob;
• possibility of installing a heating element and a gas burner;
• high quality workmanship;
• deep firebox (56 cm);
• outlet water temperature up to 95 degrees.

Flaws:

• not the highest efficiency (75%).

Let's start, naturally, with maximum power . You don’t need to think that if the boiler’s characteristics say “10 kW/100 m2”, then it is small house enough to spare. Firstly, the power of any solid fuel boiler very much depends on the quality of the fuel; moreover, the characteristics indicate that it is for coal (it has the highest heat transfer). Try to add more firewood - and the house will immediately get colder, well, what if the firewood also gets damp... In addition, a higher-power boiler will also have a larger firebox - which means it will have to be heated less often.

At all, the need for frequent addition of fuel is a common problem with solid fuel boilers. There are several solutions:

• Bunker boilers- they automatically “feed” the firebox from a separate container (hopper). Such systems were developed primarily for pellets (fuel granules), which are very convenient to feed with an auger, but now there are also models that can operate on coal.
• Long burning boilers They have an increased loading volume, and the combustion process itself is not entirely usual - the fuel burns from top to bottom. But they also have their own not always convenient features - we wrote about this earlier in the rating.

But in any case, a “long-lasting” boiler will become more complex and expensive, especially with a bunker. Then how about combined boiler? In them, heating is provided not only by the combustion of fuel, but also by a heating element installed inside - even if the boiler goes out, the electricity will continue to maintain at least some temperature. It is convenient to leave such cauldrons overnight - you won’t wake up in the morning feeling that your tooth is missing a tooth. Often retrofit kits for gas or diesel fuel are offered for such boilers. Some models even initially provide for automatic switching to liquid or gaseous fuel if there is no fire in the firebox. In general, this option is interesting if only because when it becomes possible to connect the house to gas, you won’t have to change the boiler, buy a new one, or redo the connection: you can simply put a gas burner on the old one.

An important point - heat exchanger design. Perfect option- cast iron: a thick-walled monolithic heat exchanger, if the manufacturer does not “miss” cavities and microcracks in the casting, will be truly eternal, and will also withstand high blood pressure no problem. But such a boiler will be both more expensive (it may not fit into the budget) and heavier (the strength of the floor is an issue; you may have to strengthen it). Steel heat exchangers have an inevitable risk of weld leakage, and the walls are usually thinner. Therefore, you should at least buy a heavier boiler, and look at reviews of a specific model before buying - it’s true that the reviews themselves have been buying for a long time... So, when choosing a solid fuel, it’s better to go to the forums, and not to popular review sites that have been occupied by paid praise.

Comfortable life in the cold season is impossible without heating, unless you decide to spend the winter in Thailand or on some other exotic islands. As for stoves and boilers, a long-burning boiler is a very good alternative to other types of heating devices. It all depends on preferences and goals.

Let's say that in addition to heat in the house you are also interested in hot water supply, in this case you should pay attention to a long-burning double-circuit solid fuel boiler. Also, most likely, you will come across long-burning pyrolysis boilers with a water circuit - unlike the first ones, manufacturers claim that they provide much higher efficiency indicators, because secondary gases will be burned and not released through the chimney. As for the price, long-burning solid fuel boilers Russian production are cheaper than imported analogues.
