Energetic resources are becoming more expensive - this is a fact, so the issue of saving energy has become especially acute lately. This also applies to heating systems apartment buildings. The cost directly depends on the method of supplying heat to residents, of which there are currently two: centralized and autonomous.

Mini-boiler room in an apartment building and its advantages

If with centralized heating everything is more or less clear, then with autonomous heating it’s not entirely clear. Of course, in addition to the advantages, mini-boiler rooms in apartment buildings also have a number of disadvantages. Let's look at the question one by one.

The design of chimneys is included in the list of tasks regulated by Rostechnadzor of Russia. Pipes are classified as hazardous production facilities, so their design and installation can only be carried out by qualified enterprises.

In accordance with regulatory documents, the person responsible for the gas facilities of the enterprise is responsible for eliminating any accidents and extinguishing fires in the boiler room. He also develops an emergency response plan, which is agreed upon with all management and the fire service, and approved by the chief engineer.

Any boiler room, regardless of its configuration and equipment, is a potentially dangerous technical room, therefore Special attention During its production, safety issues, especially fire safety, should be taken into account. Without automation and control mechanisms that negate most risks, the boiler room simply will not be put into operation.

Modular boiler rooms are boiler equipment, located in a special module (or several modules). Design features make it easy to transport ready installation to any place, quickly install and implement commissioning works, as well as guarantee the high efficiency of the unit due to assembly at the manufacturer.

If it is necessary to quickly and easily provide space heating, mobile boiler rooms are used - block-modular installations on skids or chassis, which are delivered directly to the designated location.

Every year the cost utilities, be it electricity or, is growing rapidly. Unfortunately, this is happening both due to the usual inflation and rising energy prices, and because of the banal greed of service providers. That is why today more and more people are looking for an alternative that allows them to reduce fees, which, apparently, will become simply unaffordable in a few years.

Autonomous boiler room in apartment building

And many people find a solution to this problem. One boiler room per apartment building is able to fully satisfy the needs of all residents, providing them high-quality heating, as well as supplying the required amount hot water. However, installing your own autonomous boiler room is an extremely serious decision that cannot be made without thinking everything through and weighing the pros and cons a hundred times. And to do this, you should know both the pros and cons of this solution.

So, you are thinking about the possibility of installing your own boiler room, which would heat the entire apartment building and supply hot water to each of the apartments. What advantages and disadvantages should you know about in order to make the right decision that will not make you regret it in the future?

Scheme heating system in an apartment building

First, it’s worth talking about the shortcomings, since there are significantly fewer of them.

This concludes the main disadvantages of an autonomous boiler room. Of course, they are very significant, which is why today not every home has a mini-boiler room installed. But still, the number of such mini boiler houses is growing rapidly. Why? Due to the below advantages autonomous heating.

1. Complete independence from city monopolists in housing and communal services. Everyone knows very well that in every city there is only one company that provides heating and hot water services to residential apartment buildings. And they can increase the cost of their services almost uncontrollably. If you install your own boiler room, then the monopolists will no longer have leverage over you.
2. Reducing heat loss to a minimum. As practice shows, when passing through many kilometers of heating mains, the coolant (hot water) loses up to 30% of the heat received (depending on the distance from the city boiler house). Example of heat loss in an apartment building

   And end consumers also have to pay for this heat. In autonomous heating systems, heat loss is measured in fractions of a percent. So due to this, the payment is reduced by a third.

3. A boiler room that heats one house, not thousands, is easy to set up. If the apartments become too hot, you can easily reduce fuel consumption, and on frosty days - increase it. Thanks to this, the temperature in the rooms will always be optimal, suiting each of the inhabitants. There is no need to ventilate the premises, lowering the temperature and at the same time releasing heat to the street, for which a lot of money was paid. But at the same time, you won’t have to use additional heat sources ( electric heaters) to maintain enough high temperature in the apartment.
   
4. To keep it in perfect order, it is enough to hire one dispatcher who monitors the readings of all instruments, as well as one or two visiting technicians who are involved only when breakdowns are detected. If your house is connected to the city heating main, you will have to pay for the services of not only dozens (or even hundreds) of ordinary installers, but also hundreds of accountants, directors, their deputies, secretaries, drivers and many others. This also saves a lot of money.
5. In most cases, connected to the city heating plant, it starts from October 15 and ends by April 15. And even if autumn and spring are unusually cold or warm for a given area, change the start and end dates heating season no one will.
   Therefore, in the off-season, apartments are often too hot or too cold. The presence of an autonomous boiler room allows you to turn the heating on and off exactly when necessary. Most often, such decisions are made by the council of residents of the building. Of course, this allows you not only to reduce heating costs, but also to maintain optimal temperature indoors, regardless of the temperature outside the walls of the house.

What conclusion can be drawn from all of the above?

An autonomous boiler room needs more attention and constant care by residents or specially hired specialists.

But it allows you to save a lot of money every month. Therefore, all initial costs will be compensated quite quickly, and very soon you will notice that you have free money that previously went to pay utility bills.

Where should the boiler room be located?

A very serious issue is correct location boiler room Most often, in apartment buildings, boiler rooms are installed either on the roof or in the basement. provide for the presence of the latter only in the basement or.

True, sometimes you can also see boiler rooms located in small buildings located a few tens of meters from the house. This could become a good decision: there is no need to lift and install equipment on the roof of the building, but at the same time there is no threat of explosion due to fuel leakage and its accumulation in the basement of the building.

But still, this method is not very popular: the need for additional construction, pouring the foundation and carrying out a large amount of earthwork scares off many potential owners of autonomous heating boilers. Therefore, only two options are usually considered - a boiler on the roof and in the basement. And it’s worth talking about them in a little more detail.

This is what a boiler room looks like on the roof

What is good about a boiler room in the basement?

Installing a boiler room in the basement usually causes significantly less hassle and problems: there is no need to lift equipment weighing many centners onto the roof of a five-story (or higher) building. In addition, there is no need to carry out a series of complex calculations to determine whether the roof will withstand additional load, and if not, then how much and how best to strengthen the load-bearing structures.

However, there are certain restrictions: the boiler room in the basement should not operate on explosive fuel.

Therefore, gas and diesel boilers cannot be installed in the basement. The fact is that the fire and explosion of fuel tanks in the basement of the building threatens the integrity of everything apartment building, as well as the life and health of residents. Only solid fuel and electric boilers can be installed in the basement.

An example of a boiler room in the basement of a house

The latter is inconvenient due to the high cost of electricity: the cost of maintaining an electric heating boiler is almost impossible to recoup. Solid fuel ones are difficult to maintain: fuel (wood, coke, coal, peat) must be loaded manually, 2 to 4 times a day.

It is also worth noting that when installing a boiler room in the basement, serious problems may arise. Its top point should be higher than the house in the basement of which the boiler room is installed, as well as higher than the houses located nearby. Although some take this problem into account.

Question from a reader: “Please help me understand the issue of the cost of heating and hot water supply. Our house is served Management Company, there is a roof boiler room on the roof of the house, but the cost of heating and hot water supply services is at the city level. Why and what is the advantage of a roof boiler house? And after a few years of wear and tear, who will pay for the purchase of a new boiler?”

So, considering this issue, we decided to highlight several points regarding autonomous heating.

1. By what principles are tariffs for heating and hot water services set in the case of a rooftop boiler house?

2. What are the advantages of autonomous heating (roof boiler room)?

3. Maintenance and repair of equipment for autonomous heating.

1. An autonomous boiler house (in particular, a roof boiler house) is a room with a heat generator or a whole complex of buildings created to generate heat for the purpose of heating one structure. The boiler room is the main element decentralized system heating and hot water supply (DHW) and may be owned by residents or owned by a legal entity (for example, a Management Company).

In the event that the roof boiler room is the common property of the residents of an apartment building, the payment for consumed resources is set by the owners on the basis of an agreement with the resource supply organization (RSO). RSO only services the roof boiler house (homeowners and the resource supplying organization enter into an agreement to perform the work). And the decisive role in setting tariffs is given to the provider of utility services, which RSO is not here. The provider of utility services (this can be a homeowners association) is guided by government decree of the Russian Federation No. 307, according to which “in the production of thermal energy for heating an apartment building using an autonomous heating system that is part of the common property of the owners of premises in an apartment building (in the absence of central heating), the amount of payment for heating is calculated based on the readings of metering devices and the corresponding tariffs for fuel used for the production of thermal energy..." and "when preparing hot water using in-house engineering systems apartment building (in the absence of centralized hot water preparation), the amount of payment for hot water supply is calculated based on meter readings and the corresponding tariffs for cold water and fuel used for preparing hot water..." (clause 18)

If the resource supply organization (RSO), being a legal entity, owns a rooftop boiler house (homeowners and the resource supply organization enter into a purchase and sale agreement for the boiler house), then it is a heat supply organization and provider of utilities (according to Federal Law of the Russian Federation No. 190 “On Heat Supply”) with activities regulated by the state. Therefore, tariffs for resource consumption are set by the state department according to the tariffs of the city (region) administration. Current information on all tariffs can be found on the official website of the department.

In order to find the answer to the principle by which the cost of services for heat and hot water is calculated, you should find out how legal relations are organized in the situation under consideration. If the Management Company is the full owner of the roof boiler house (there is a boiler house purchase and sale agreement), then tariffs should be made according to citywide tariffs.

If it turns out that your Management Company is not a provider of utility services and only serves the boiler room, the tariffs do not comply with the legislation of the Russian government, and you can file a claim with the Court.

2. Roof boiler rooms, which are installed on the roof of an apartment building, have a number of advantages over conventional ones centralized systems heating and hot water supply.

a. Perhaps the main and serious argument in favor of using autonomous heating and rooftop boiler houses is the significant savings in energy resources. According to statistics, rooftop boiler houses reduce resource costs by 45% compared to centralized open systems.

b. Autonomous heating - controlled. This means that home owners have the right to regulate temperature regime during the heating season and during the day. In practice, you can see that such heating control allows you to save up to 30% on fuel payments.

V. Roof boiler rooms do not require constant maintenance, so the presence of people during the operation of the boiler room is not necessary. Full control over the condition and operation of the boiler room is carried out through the control center.

The boiler room, located on the roof of the building, eliminates a number of problems:

- no need to allocate space for plot of land for the construction of a boiler house;

— provides free access to the pipeline;

— provides excellent conditions for equipment (no pressure on pipes, units, boilers, etc.);

— convenient air supply to the boilers;

— saving of material for the manufacture of the chimney.

d. Safety of operation of roof-top boiler houses is another big plus in the direction of autonomous heating. In the event of unauthorized entry of smoke emissions into the apartment, the risk of a serious accident is not high.

e. Roof boiler rooms are environmentally friendly due to good dispersion and volatilization of gases.

3. Returning to Resolution No. 307 “On the procedure for providing utility services to citizens”, one can see that “... the costs of maintaining and repairing in-house engineering systems used for the production of thermal energy, as well as the costs of maintaining and repairing in-house engineering systems used for cooking hot water are included in the fee for the maintenance and repair of residential premises" (clause 18 of the RF PP No. 307).

In addition, in accordance with the Housing Code of the Russian Federation, “owners of premises in an apartment building bear the burden of expenses for maintaining common property in an apartment building” (Article 39).

Consequently, installation of a boiler or other failed element of a boiler installation is carried out at the expense of the residents. In practice, the cost of monthly payments for heat and hot water can include a percentage for unforeseen repairs or installation of a new boiler room, which is required every 25 years.

A heating device installed on the roof is analogous to a boiler in the basement. It exists in three types, differing in installation and operation. Depending on the installed boiler, users are able to save a little.

Gas roof boiler room

The device has the following positive aspects:

• High ratio useful action. Thanks to the use of liquefied gas, which releases energy when heated, fuel consumption is reduced.
• There are almost no external communications. This reduces costs. Heat loss is also reduced.
• In low buildings (up to 26 m) there are no additional installation requirements, which reduces the cost of the project.
• Automation, which reduces operating costs.
• The device is not turned off for annual inspection, which allows daily use of hot water.

The device has several limitations. To accommodate the boiler room, the roof is strengthened by installing a concrete pad. Preliminarily calculate the load that the building can withstand.

They bring it for installation special equipment, the operation of which creates inconvenience for residents. The cost is also unpleasant: the costs go towards creating the project, laying the gas carrier, and the automation responsible for control. Additionally, protective measures and a fire extinguishing system are installed.

Installation

To create a heating system on the roof you need to build separate room. The roof boiler room is autonomous: once it is started, it is enough to carry out rare scheduled checks.

Important! Standards for installation and operation of the device are prescribed in SNiP. Additional information can be found in the “Design Rules” for roof boiler houses.

The process depends on the device variant. There are 2 types - built-in and block-modular.

Built-in

Boiler rooms built into the roof are used in new buildings. Such a device is installed only in a building under construction or in a building that has space to accommodate a thermal station. For built-in boiler rooms, the additional load on the walls must be calculated multi-storey building, create a fire extinguishing module.


The main advantage of the device is the ease of creating and implementing a project. Along with the installation, work is carried out to install sound-absorbing coatings and vibration protection. Conducted at the finishing stage, they are more efficient during operation.

Block-modular

To place a roof boiler room in a constructed building, a block-modular type is used. The most common installation option is during overhaul. A roof boiler room is installed in case of restoration of the heating system. The project is created based on the characteristics of the building. The device is then created and delivered to the required building.

Before installation, the roof is inspected:

• Check the condition of the load-bearing supports.
• Impose protective covering to the installation point. It is a concrete pad.
• Sound-absorbing material is installed.

Having completed the preparation, the boiler room is turned on heating network. It is set up and the coolant is distributed. Having connected to the heating, they begin operation.

What to pay attention to

Before installing the device, it is necessary to take into account that it creates a load on the structure. Because of this, the following rules must be observed:

• It is prohibited to place the boiler room on the ceiling above residential premises.
• It is prohibited to place equipment in premises adjacent to residential premises.
• When designing, the size of the house in which it is planned to be located is observed.
• When designing, an emergency shutdown system is created.

Price

A rooftop gas boiler room in an apartment building is common property. Therefore, installation and maintenance costs are paid by the owner. If the system is installed during a major renovation, the funds are spent from the housing fund. In such a case, there may not be enough money - residents decide to pay extra.

Important! The cost is determined by the amount of funds spent on the creation and implementation of the project: delivery of components, placement, configuration. The price also includes the creation of emergency shutdown and fire extinguishing systems, insurance. The total cost of equipment reaches 10 million rubles.

Advantages

In order for the roof boiler room of a residential building to operate stably, it is necessary to carry out careful calculations and not skimp on installation. Equipped on the roof of a house, it has advantages over other systems:

• Installed on the roof of the house, the boiler room reduces energy losses during the transfer of coolant from roof equipment to radiators. This reduces the cost of heating services by up to 30%.
• Automation serves to use hot water during periods of absence, when the supply is turned off to check the media.
• Maintenance of the device is reduced due to autonomy. Functionality checks are carried out rarely, by agreement with the service company.
• Before operation, many checks are carried out to detect malfunctions and safety errors.

Flaws

The heating system is not ideal because it has the following disadvantages:

• Roof boiler equipment placed in an apartment building creates a large load on the structure.
• The device must not be installed in buildings higher than 9 floors.
• During operation, vibrations are created that disturb residents of the upper floors.
• High cost.

An installed gas roof boiler room in an apartment building provides significant cost savings, reducing heating and utility costs by approximately 30%. At the same time, the structure must comply construction requirements, set out in , as well as the specially released addition P1-03 .

Types and arrangement of roof boiler houses

Acceptable types of roof boiler houses are described in detail in SNiP. IN technical documentation, attention is paid to the requirements, compliance with which makes it possible to install heating equipment on the roof.

The standards separately stipulate the possibility of operating a boiler room of built-in and block-modular type. Each type of technical and design solution has its own limitations and features. In general, placing boiler equipment on the roof has several advantages:

• There are no costs for the construction of a separate technical building.
• There is no need to build a high chimney.
• The safety of operating heating equipment increases.

When deciding on the feasibility of installing a roof boiler room, the existing restrictions specified in SNiP and PPB are taken into account.

Block-modular roof boiler houses

Gas modular roof-mounted boiler rooms for apartment buildings are specially designed to reduce the weight of the finished structure and reduce the mechanical load on the roof of the building.

The following steps are required for installation:

• A platform resting on load-bearing walls and other building structures. Before installation, an examination is carried out aimed at determining the load-bearing capacity and identifying measures to strengthen the structurally significant elements of the building.
• The covering under the boiler room is made from non-combustible materials. As a rule, a concrete pad with a thickness of 20 cm is poured for this.
• Separate measures are provided to ensure safety (manufacture of railings around the perimeter of the roof) and increase the sound insulation of the modules.

Installation of block-modular heating equipment requires the preparation of a separate project and is suitable for buildings in which it was not initially planned to heat the premises in this way.

A modular boiler house is a fully equipped thermal station, ready for operation. All equipment is built into the module. The BMK is additionally equipped with rooms for service personnel.

Built-in roof boiler rooms

Built-in roof boiler rooms on the roofs of residential buildings can only be installed in cases where at the manufacturing stage project documentation, the installation of a thermal station was envisaged. This solution takes into account the load-bearing load on the walls of the building, fire safety and other operational details.

It is much easier to produce and approve a project for a built-in boiler room. Soundproofing, noise-absorbing and anti-vibration measures are carried out simultaneously with the construction of walls and finishing works, which significantly increases their efficiency. In fact, built-in boiler rooms are provided extremely rarely, mainly in new houses, the construction of which began in the last 5 years.

Rooftop boilers

Boiler equipment allowed for installation on the roof, according to SNiP II-35-76, has high automation of operation, sufficient to ensure heating of the building without the constant presence of personnel and technical work nicknames

Domestic thermal units, for all their advantages, are not autonomous. Therefore, the choice mainly falls on products from Italian, German and other European manufacturers:

• Futera.
• Rendamax.
• Wessex.
• Viessmann.
• Buderus.
• Protherm.
• Ferroli.
• Vaillant.
• Lochinvar.

When choosing a suitable boiler, focus on thermal power, availability of registration and license issued by Rostechnadzor, adaptation to domestic operating conditions and cost.

Standards for the design of rooftop boiler houses operating on gas

SNiP for rooftop gas boiler houses has not changed since 1976 (SNiP II-35-76 “Design standards. Boiler installations"). But, the emergence of new technologies and modification of heating equipment led to the appearance of an addendum that describes in detail all the requirements (P 1-03 “Design of autonomous and rooftop boiler houses”).

The basic requirements and standards for the design of rooftop boiler houses remain the same and include the following provisions:

• Installation not allowed technical room directly on the ceiling of living rooms.
• It is prohibited to connect the boiler room to the walls of residential premises.
• Operation of a fully autonomous station is allowed.
• It is mandatory to have an alarm system and a system that sends a signal to shut down in case of emergency situations.

The minimum height of chimney pipes above the roof is not less than 0.5 m above the highest point of the building and structures installed on top. The type of heat generator and its power are taken into account. The lifting height of the pipe may vary depending on nearby buildings and other technical characteristics.

The specified SNiPs affect four important areas of design, requirements for: placement, gas supply, electrical supply and compliance with safety regulations.

Requirements for roofs for boiler rooms

Regulatory documents for the design of a roof-mounted block boiler heating unit prohibit the use of this type of heating for the following types of buildings:

• Public buildings - it is prohibited to place a built-in boiler room above premises with a simultaneous occupancy rate of more than 50 people. Hospitals, clinics, sanatoriums, schools, nurseries, etc. are subject to the ban.
• Apartment buildings - standards regulating the operation of a boiler room in an apartment building indicate a direct prohibition of installing a station exceeding the total thermal power of 3 mW.
  Power restrictions also affect built-in thermal stations. General rule– a ban on exceeding thermal power by more than 15% of the total heat demand of the building.

The following types of restrictions are specified separately:

• Height limitation - in the old SNiP II-35-76 (designers still refer to it), there is a limit on the height of the building on which the installation of a roof boiler room is allowed. Maximum height 26.5 m, which equates to 9 – storey building. In the joint venture currently in force, height restrictions are not specified at all.
• Size restrictions - the boiler room should not exceed the size of the building itself. It is not allowed to increase the width of the walls and other measures related to the re-equipment of the roof and an increase in the weight load on the load-bearing walls.
• Restrictions on location - roof-mounted gas boiler houses for apartment buildings are established exclusively after an examination and implementation of measures to strengthen the load-bearing structures. Installation on floor slabs or placement next to the walls of residential premises is not allowed.

Any deviations from technical specifications on the installation and operation of roof boiler houses on natural gas, leads to a refusal to commission and recognition of the station as inoperable until the violations are eliminated.

Gas supply to the boiler room located on the roof

The design recommendations set out in SNiP II-35-76 are additionally accompanied by “Safety Rules in the Gas Industry”, which contains several provisions regarding the provision of gas supply to the thermal station:

• The pressure in the line should not exceed 5 kPa.
• The gas pipeline is carried out along external wall building. Tapping into a pipe to connect other sources of gas consumption is not allowed.
• The laying of the gas pipeline along the roof and walls must be open. Closing the main pipeline with gratings, removable and non-removable structures is not allowed.
• To regulate the flow and turn off the gas supply, shut-off and control valves are installed at the main line entry into the house and at the connection of each heat generator. At the installation site of the fittings, artificial lighting is required.
• Purge pipelines with a diameter of at least 20 mm are provided.

Separately, taking into account gas supply, a thermal scheme is developed:

• Heating - a dependent circuit is used, which provides a mixing unit for heat release. A separate thermal arrow is installed on each facade or zone of the building. In a roof boiler room, the coolant temperature should be no more than 115°C.
• DHW – for hot water supply, installation of a separate heat generator is allowed. Hot water is supplied according to closed scheme, through heat exchangers.

The laying of heating and hot water pipelines from the boiler room should not intersect with the gas pipeline of the building. At the stage of development of project documentation, a decision is made on the placement of each pipeline in compliance with the rules specified in the SP and PPB.

Electrical supply to the boiler room on the roof

The electrical project is developed in accordance with the current rules for the construction of electrical installations (PUE). According to the classification, rooftop boiler houses are equal to the second class in terms of the required reliability of power supply.

The following measures are provided:

• Lightning protection - the project is developed with the standards described in. At the same time, both the gas pipelines themselves and the heating equipment connected to it.
• Lighting is carried out using sealed lamps with a metal protective mesh.
• The need for backup power supply to the roof boiler room is provided. In the event of a power outage, it is necessary to provide power to turn on the backup circulation pump and ensure the operation of the automation, alarm and warning systems.
• To disconnect the boiler room from the power supply, a switchboard is installed, located outside the premises of the thermal station.

Fire extinguishing of a roof boiler room

Technical conditions for design and operation must take into account fire extinguishing measures in the boiler room. According to SNiP II-35-76* clause 17.5:

“...A building with a height of more than 12 m, not equipped with an internal fire-fighting water supply system for supplying water for fire extinguishing, and having a roof boiler room, must be equipped with a “dry pipe” leading to the roof with fire hose heads with a diameter of 70 mm.”

If an internal fire extinguishing system is provided, the boiler room is equipped with two taps with a diameter of 50 mm.

There are several specific fire safety requirements for premises for placing a rooftop gas boiler room in an apartment building, including the following recommendations:

All requirements are aimed at minimizing the occurrence of possible emergency situations, therefore, in some cases, local supervisory authorities may recommend additional safety measures. Before starting the preparation of project documentation, you should contact the regulatory authorities for clarification of the provisions stipulated in SNiP, PPB and SP.

Commissioning of a roof boiler room

Rules technical operation stipulate the delivery of the boiler room and its commissioning, and divide all actions into two stages:

1. Preparation of design documentation and approvals.
2. Carrying out technical work on the installation and arrangement of a thermal station.

At the stage preparatory work and arrangement of the boiler room, the following activities are carried out:

• Measures aimed at shock absorption and noise insulation - noise pollution is not allowed to exceed 60 dBA inside the boiler room and 35 dBA in nearby residential areas. The result is achieved in two ways:
  1. selection of heating and other equipment equipped with soundproof casings.
  2. carrying out work to install noise-absorbing and vibration-reducing barriers.
• Organization and implementation of work on maintenance– personnel undergo special training and receive the appropriate license. After installation of boiler equipment, it is allowed to conclude an agreement with residents for the maintenance of boilers and related equipment.

The preparation of design documentation and approvals falls entirely on the shoulders of the contractor constructing the building, or on the representative of the housing cooperative, who authorized him to draw up the necessary documents.

Cost of a boiler room on the roof

The financial costs of a rooftop boiler room are usually borne entirely by the residents of the apartment building where it is installed. The total cost of a thermal station consists of several components:

• The type of boiler chosen - the boiler room is assembled and equipped at the request of the customer. Budget versions are equipped with boilers from Italian and Polish manufacturers. The most expensive station will be the one equipped with German Viessmann boilers, Buderus.
• Additional work - in addition to installing a boiler room, measures are taken to eliminate structural noise, install a fire extinguishing system, power supply, etc. Total costs will increase by approximately 30% compared to the cost of the thermal plant.
• Boiler house insurance – annual costs for purchasing an insurance policy are mandatory, without which it will be impossible to put a rooftop boiler house into operation.

Full cost, including production of design documentation and receipt of all necessary approvals, costs 5-10 million rubles, depending on the number of residents and the selected power of the heating equipment.

Roof boiler room - pros and cons

Any heating of a house or apartment has its advantages and disadvantages. This design and design solution, which has no pitfalls, satisfies the thermal characteristics and is cost-effective.

When determining whether a rooftop boiler room is a viable option for heating a residential building, the advantages and disadvantages are considered separately. Pay attention to the opinions of experts and reviews of consumers themselves.

Advantages of a boiler room on the roof

The main advantage is that the boiler room on the roof of a multi-storey building operates as a completely autonomous thermal station. Accordingly, there is no need to conclude contracts and pay for intermediary services of various organizations of Heating Network and similar ones, which leads to several more advantages:

• Supply of coolant and hot water to multi-storey building from a rooftop gas boiler room, carried out directly to the building on which the station is installed. This leads to a reduction in heat loss when delivering coolant from the boiler room to the consumer. There is no need to pay for heat losses that exist with centralized city heating.
• Due to the complete automation of the heating process, the fee for maintaining the boiler room is reduced to a minimum. If necessary, an agreement is concluded with a contractor who simultaneously services several thermal stations.
• The heating season begins when necessary, and is not equated to a specific date.
• High safety - the gas boiler room is designed in such a way as to ensure maximum operational safety. The prevention of emergency situations is facilitated by many requirements and approvals that boiler equipment undergoes before it is put into operation.

Heat costs are reduced by approximately 30%. At the same time, the quality of the services provided increases significantly. The batteries become really hot, and you don’t have to overpay for losses during heat transportation.

Disadvantages of roof-mounted boiler houses

Rooftop thermal stations have several disadvantages that are taken into account at the stage of preparing design documentation:

• Installation restrictions - for a roof boiler room, the number of storeys allowed is no higher than 9 standard floors. As mentioned above, this requirement can be challenged, but this does not always work out in practice.
• Problems with vibration - powerful circulation pumps, the boiler contains turbines that produce high-intensity noise and vibration. And this significant shortcomings for residents of the top floor.
• High cost - production and purchase of design documentation, noise insulation work, etc., will cost 5-10 million rubles. To save money, they order a turnkey boiler room.
• Disadvantages of rooftop boiler houses at the regulatory level - as already indicated, many officials in design organizations cite outdated building codes as the main requirements. To “convince” them may require repeated appeals to the courts. It all depends on the region where the documents are processed and the officials themselves.
