Rooftop boiler house, its maintenance and use can be beaten either in block-modular execution, or if its construction was negotiated even before the construction of the house itself - this brand is called "built-in". But in most cases, this structure is a set of blocks-devices that are assembled in a factory environment, brought to a multi-storey building and assembled on the spot.

Advantages of this installation on the roof of a building

Assembling a rooftop boiler house - extracting an integral autonomous thermal station. Which has many advantages:

• No need to sign contracts with multiple institutions and pay them for those. maintenance of equipment on the roof of the house;
• Reduction of heat losses, which nevertheless take place if the object is installed at a distance from the heated structure. The heating lines through which the coolant is supplied to the dwelling are improved, which means their efficiency is much higher;
• Payments for heat supply are reduced to the lowest mark, also because this installation in a high-rise building works automatically and does not prescribe the constant presence of service workers;
• It is possible to open the OP and close it at a time when it is comfortable for residents. In case of early cold weather, it is possible to turn on the boiler room of a residential building much earlier than planned;

Statement of these objects

This entity is an autonomous structure that provides heating and hot water supply in residential and industrial premises.

The standards for planning, setting up and using this equipment are written in the SNiP for roofing installations. Additions and changes that are associated with the assembly and release of more high-tech equipment are indicated in certificates and documentation.

Types of aggregate data

There are two types of this equipment - built-in and block-modular type. Let's take it in order:

Installations built into the roof are used in new buildings. This unit is placed only in a house under construction or a building in which there is a place for the location of a heating plant. For built-in units, they must calculate the additional power on the walls of an apartment building, form a fire extinguishing module.

The main advantage of the equipment is the ease of formation and implementation of the plan. Together with the assembly, work is carried out on the layout of noise-absorbing coatings and vibration protection.

Block-modular unit

For the installation of a roof boiler room, a block-modular type is used. This is a more common variation of the production - during the overhaul. This unit is installed in case of modernization of the heating configuration. The plan is formed on the basis of the characteristics of the structure. Then the device is created and brought to the desired building.

Before installing, perform a roof check:

1. Verify the condition of the supporting structures;
2. Lay the safety cover at the assembly point. Behind it is a pillow of concrete;
3. Produce the installation of a noise-absorbing product;

Having completed the development, they connect the equipment to the heating network. It is adjusted, a heat carrier is placed. Having connected to the heating, they begin to use.

Equipment erection points on the roof

This, of course, is the formation of the project and the setting - the two main procedures in the construction of these units. In order to avoid all sorts of errors that lead to malfunctions, as well as the possible change of most of the equipment, you should contact the design and assembly company. Therefore, the technical requirements, the subscriber will be offered a large number of services, as well as proper engineering planning. In addition, specialized workers will help you choose more the best modification unit, choose the right equipment, thus precisely satisfying the wishes of the customer. In addition, there will be correct installation, in strict accordance with all standards and regulations.

The cost of the roof boiler house of a residential building

What are the points to pay special attention to?

Before assembling the equipment, it should be taken into account that it forms a load on the structure.

Based on this, it is prescribed to comply with the rules and regulations:

1. It is not allowed to place the installation above floor slabs above inhabited rooms;
2. It is not allowed to place equipment in a room that is close to residential;
3. When planning, the dimensions of the building in which the unit will be placed are strictly observed;
4. When planning, an emergency shutdown structure is formed;

Some disadvantages

1. The rooftop boiler system can be installed on residential buildings no higher than 9 floors;
2. Strong fluctuations in the action of the pumps of the structure, cause inconvenience to people on the upper floors;
3. High price category of equipment;

Recently, more and more often you can hear about the desire to save energy resources and increase the cost of fuel.

The amount of savings in fuel and energy resources and material resources spent on providing heat to consumers will directly depend on the method of heat supply.

How can you provide heat supply to multi-apartment residential buildings?

There are two options - to power the heat pipelines from the main heat networks or install an autonomous heat point.

Both options are good, however, the presence of an individual heat point for several apartment buildings and autonomous heating with the use of energy-saving means will please more. Why?

Because the distance between the pair "heat point - consumer" is minimized, thereby reducing heat loss along the heating network line. This type of heating is called decentralized, or autonomous.

Lower percentage of heating and hot water costs apartment building- and all because the costs of transportation and delivery of the coolant to the end user are reduced.

Simply put, the source of heat supply is practically nearby, and therefore the time for supplying heat to residential buildings and the percentage of heat losses are reduced. This also leads to a reduction in the cost of maintaining, servicing and repairing heating networks.

The efficiency of heat supply systems - as a result, follows from the previous factor. Since the source of heat supply is nearby, then the amount of payment utilities for hot water and heating is somewhat lower.

Independence from the citywide heating schedule. In other words, while heating has not yet been given in the city (“because the heating season has not come on schedule”), and the temperature is already low outside, apartment heating from an autonomous heat source will come in handy.

In addition, each consumer will be able to choose the optimal temperature conditions for his apartment - turn off / turn on the heating system only for his apartment, adjusting the level of heat supply.

In this case, there are no connection problems due to "technical" and seasonal reasons.

Lower cost and higher payback of new buildings with an autonomous source of heat supply.

A separate boiler room in each house will increase the free space in the yard. Click to enlarge.

This is more likely to play into the hands of developers, because in the case of the “traditional” construction of an apartment building, you have to spend quite a lot of time getting permission to connect a new building to a centralized heating network, install a meter (which is mandatory for any new building today).

The presence of "additional free space" within the whole microdistrict. This also contributes to the implementation of housing programs, the construction of new buildings and the arrangement of microdistricts not for heating mains, but for the infrastructure of the districts.

In addition, providing apartment buildings with an autonomous source of heat supply is also possible if there is already an established gas supply system in the construction area.

Flaws

However, along with the advantages that consumers of decentralized heating and hot water have, there are a number of disadvantages:

1. The need for additional space allocated for the construction of an autonomous boiler house.
2. Non-environmental operation of the boiler room. For a gas boiler house operating autonomously, it will be necessary to additionally equip an exhaust gas exhaust system in order to reduce smoke emissions into the atmosphere as much as possible, having obtained the MPC value required by SNiP (maximum permissible concentrations).
3. Price. Since autonomous heating today is not yet as popular and in demand as centralized heating systems, the production of boiler equipment for it has not been put on the conveyor. Consequently, prices for decentralized heating and hot water systems are still high.

Is it possible to eliminate the above shortcomings completely, or at least minimize them? Can. An additional area for an autonomous boiler room can be "found" on the roof of a multi-storey building that will be heated.

The "salt" is that the so-called rooftop boilers require flat roofs for their installation.

An increasing number of new buildings are already equipped with a roof-top boiler house with equipment installed above and top-mounted piping.

Of course, the installation of additional equipment will cost, and the decentralized heat supply of one apartment building itself is not cheap, but it will all pay off faster than if the house were simply connected to a centralized heat supply system.

Varieties of decentralized heat supply

Another example of autonomous heating of a multi-storey residential building is a block boiler house, consisting of a separate module. Block or modular boilers can be transported as they are delivered in containers.

The use of modular boiler rooms in an apartment building. Click to enlarge.

Their execution does not require the construction of a new building specifically for boiler equipment– the entire installation is already “encased” in a container, in addition, the module is thermally insulated, and the assembly is carried out directly at the factory.

Previously, such blocks were used as heating systems for temporary structures (change houses), but now they are offered (after a number of modifications) as an alternative to centralized heating.

But the best option for autonomous heating is an apartment heating system powered by a main gas pipeline or through a power supply network (depending on the type of boiler), the “core” of which is a wall-mounted boiler (gas or electric).

Why wall mounted? Because wall boilers have a number of advantages:

1. Easy to install, easy to hang on the wall using a set of fasteners (fasteners must be supplied with the boiler equipment)
2. They are light in weight and small in size, do not take up much space in the room
3. With their size, they have good power (10-25 kW) and are able to heat a room up to 100 m2 - and this is quite enough for one four-room apartment
4. Available in both single and double

If the owner of the apartment plans to install a wall-mounted gas boiler as heating equipment, then he should check the completeness of the equipment, namely:

1. Boiler with two circuits (working both for space heating and hot water)
2. Combustion chamber - closed type
3. The presence of a fan to provide forced draft (fence fresh air from the street) and the removal of combustion products through the chimney
4. Pump for forced circulation of the coolant
5. Electronic ignition and full automation - for rational use fuel

An additional advantage in autonomous heat supply can be considered the possibility of installing a “warm floor” system - provided that the insertion of an additional pipe for taking the coolant does not affect the pressure level in the system.

In the case of an electric boiler, which also works according to a two-circuit scheme (heating + providing the consumer hot water), there will be much less difficulties: you will only have to obtain permission to allocate an additional power line, plus coordinate the insertion of the direct and return pipes into the general water supply system.

The only exception will be electrode boilers without heating elements that work to heat running water.

Possible Complications

If everything is so simple and easy, why are apartment owners in no hurry to re-equip their heating systems? The answer is simple: there is no permit for the conversion of heat supply.

No housing company will give the owner of the apartment permission to re-equip the heating system "just like that." And all because, as mentioned above, the cost of maintaining and repairing the heat supply system will decrease.

It follows that the owner of an apartment with refurbished heating will pay less, and this is already unprofitable for the management company.

Another question is if there will be several families in several apartments who want to re-equip the heating of the house, making it autonomous, and even better - residents in several nearby houses.

But in this case, the transition to autonomous heating can be fraught with such difficulties as obtaining permission to carry out all construction and installation work - and all this at the expense of willing owner-initiators.

Finally, I would like to note that it is advisable to entrust all work on the installation of autonomous heating in an apartment building to professionals who have the appropriate licenses to carry out work of this kind. Even if you just want to put an ordinary wall-mounted boiler at home.

Every year, the cost of utilities, whether it be electricity or, is growing rapidly. Alas, this happens both because of the usual inflation and the rise in the cost of energy, and because of the banal greed of service providers. That is why today more and more people are looking for an alternative to reduce fees, which, apparently, in a few years will become simply unbearable.

Autonomous boiler room in an apartment building

And many people find a solution to this problem. One boiler house per apartment building is able to fully meet the needs of all residents, providing them with high-quality heating, as well as supply the right amount hot water. However, installing your own autonomous boiler house is an extremely serious decision that cannot be made without thinking everything through and weighing all the pros and cons a hundred times. And for this you should be aware of 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 strengths and weaknesses do you need to be aware of in order to make the right decision that will not make you repent in the future?

To begin with, it is worth talking about the shortcomings, since there are much fewer of them.

On this, the main disadvantages of an autonomous boiler house are exhausted. Of course, they are very significant, which is why today not every house has a mini-boiler room installed. But still, the number of such mini-boilers is growing rapidly. Why? Due to the following advantages of independent heating.

1. Full independence from city monopolists in housing and communal services. Everyone is well aware that in every city there is only one company that provides heating and hot water services to residential apartment buildings. And they can almost uncontrollably increase the cost of their services. If you install your own boiler house, then the monopolists will no longer have leverage over you.
2. Minimizing heat loss. As practice shows, 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). An example of heat loss in an apartment building

   And end users also have to pay for this heat. In autonomous heating systems, heat losses are measured in fractions of a percent. So already 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 it gets too hot in the apartments, 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. You do not have to ventilate the premises, lowering the temperature and at the same time releasing heat into the street, for which a lot of money has been paid. But at the same time, you do not have to use additional heat sources (electric heaters) to maintain a sufficiently high temperature in the apartment.
   
4. To be contained in perfect order, it is enough to hire one dispatcher who monitors the readings of all devices, as well as one or two incoming adjusters 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, no one will change the start and end dates of the heating season.
   Therefore, in the off-season, it is often too hot or too cold in apartments. The presence of an autonomous boiler room allows you to turn on and off the heating exactly when it is needed. Most often, such decisions are made by the council of the tenants of the house. Of course, this allows not only to reduce heating costs, but also to maintain the optimum temperature in the premises, 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 from residents or specially hired specialists.

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

Where should the boiler be located?

A very serious issue is the correct location of the 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, standing a few tens of meters from the house. This could become good decision: there is no need to lift and mount equipment on the roof of the building, but at the same time there is no risk of explosion due to fuel leakage and accumulation in the basement of the building.

But still, this method is not very popular: the need for additional construction, pouring the foundation and holding a large volume land works 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 is worth talking about them in a little more detail.

What is good about the boiler room in the basement

Installation of a boiler room in the basement usually delivers much less hassle and problems: you do not need to lift equipment that weighs 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 can withstand additional load, and if not, how much and how best to strengthen the supporting structures.

However, there are certain restrictions: the boiler room in the basement should not run 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 endanger the integrity of the entire apartment building, as well as the life and health of residents. Only solid fuel and electric boilers can be installed in the basement.

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 fuels 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 can arise when. Its highest point should be higher than the house in the basement of which the boiler room is installed, as well as higher than the houses nearby. Although some consider this problem.

What problems do tenants often face in an apartment building in the winter? First of all, this is a poor-quality heat supply. It also saddens the hopelessness while waiting for the heating systems to start turning on. A gas boiler for an apartment building will help maintain a constant temperature in each apartment and save on service charges.

Residents are forced to freeze from the cold until the start of the heating season. The need to monthly pay a round sum to pay for heating finishes off the most persistent.

Installing a gas boiler on the roof will solve heating problems once and for all. The main obstacles to solving the issue of installing a gas boiler are related to obtaining permits from the administration and acquiring suitable equipment.

Usually, an autonomous gas boiler room is equipped in apartment buildings in separate rooms. For these purposes, separate rooms on the roof are suitable.

They contain all the necessary equipment for the continuous operation of the heating system. The capacity of the installed equipment should be enough to heat the radiators and heat the water in the apartments of the whole house.

The first appearance of rooftop boiler houses in Russia in the 90s is connected with the desire of investors-developers. They wanted to install high-quality and uninterrupted heat supply in the houses under construction. Centralized systems could not meet the overestimated requirements

Such mini-boiler rooms are equipped with a variety of modern appliances and a variety of fixtures. Autonomous systems use the most modern heating technologies. This allows you to use one boiler house even for several houses, which increases the profitability for residents several times.

There are several factors that determine the benefits of installing a rooftop gas boiler in apartment buildings.

First of all, this is a significant reduction in the distance from the heat generator to radiators and pipes in apartments. Due to this, heat losses during the circulation of water in the system are reduced. Approximate calculations show that the owners pay for heating an amount 30% higher than the actual cost due to heat losses.

Residents who once installed a gas boiler in the basement or on the roof of a multi-storey building note a real reduction in utility bills. Also, they are much less likely to face the need for frequent maintenance of systems: their repair, installation and reconstruction. Modern communications are different high quality and durability.

Due to the shortening of the path that water must pass from the central energy carrier, the heating rate of the system increases. Also, on average, the temperature of the batteries and hot water increases. Although this is more regulated by the setting of the gas boiler.

Roof boilers are very popular due to the fact that there is almost always no place for the construction of a ground structure near apartment buildings. The location of the boiler rooms at the bottom of the house creates an additional hydraulic load

If we compare central system heating with autonomous, then the second option wins in many respects. This is both efficiency and the rate of heating water in the system.

In addition, central heating is turned on only when certain temperatures are reached. However, the cold weather may continue for a long time until it reaches the required minimum. And the residents are forced to endure the cold and suffer.

With an autonomous system, it becomes possible to support desired level heat all year round and not depend on utilities. Thermostats are usually installed on radiators and circuits, allowing you to change the temperature depending on the needs of users. Sometimes setting a comfortable temperature allows additional savings.

Disadvantages of modern heating systems

As with any heating system, autonomous heating has its drawbacks. Although there are much fewer of them in comparison with the centralized one. Due to the fact that gas autonomous boiler houses are not very common, it is rather problematic to get reliable equipment and all the nodes adjacent to it.

Therefore, the elements of the boiler room will cost customers a round sum. Despite the high level of comfort that the systems in question provide, not all developers are willing to pay big money for it.

In the event of an emergency, the entire heating system is completely out of order. Above the heads of people is up to five cubic meters boiling water. If the pipes burst, the water will go down. Therefore, there are so many requirements for gas equipment

In addition, gas boilers must be placed in separate rooms or buildings. To do this, you need to allocate an area near the house, bring the roof to the required technical conditions, or install a block structure on the roof. All of these solutions require an infusion of additional resources either from the developer or from the general fund created by the residents.

Systems gas heating emit polluting decomposition products into the environment. Therefore, when installing boiler rooms, it is necessary to provide for the installation of filtration systems. Cleaning devices must perform their functions sufficiently so that the norms of SNiP are observed. This further increases the cost of purchasing equipment.

When building a new house, the developer has a choice: to make an autonomous heating system or connect to the central highway. To crash into the highway, you need to obtain a number of permits. Often the solution to the problem requires a round sum of money. In addition, it will take more than one month to wait for the papers to pass checks in all instances.

The high cost of work on connecting to existing networks, the difficulties in coordinating this procedure, as well as the presence of many obstacles that prevent the fast and efficient implementation of heat networks, reduce the attractiveness of autonomous systems for the developer.

Often the installation of gas boilers on the upper building envelope entails the need to strengthen the ceiling. The total load generated heating system can reach 15 tons. You can avoid such values ​​by installing flow equipment instead of capacitive

The installation of autonomous heating is also associated with a number of bureaucratic procedures. Both the initial implementation of systems and the reconstruction with redevelopment have their own characteristics. This is mainly due to the fact that you are going to use gas as a heating resource. All work with gas is strictly regulated by law.

Modern engineering developments effectively deal with a number of shortcomings. If you need to heat just one house, an excellent option would be to place a block boiler room in the attic of the house. The attic becomes heated, and the tenants of the last floor do not experience discomfort.

Such structures are developed in detail by engineers, are lightweight and are installed on bearing walls. For such options, a flat roof option is required. This subtlety is usually taken into account at the design stage. Designers carry out calculations and determine in advance a place for a boiler room on the roof of the house.

The law establishes a limit on the power of equipment on the roofs of houses at 3 MW. Some regions have a limit of 5 MW. If this power is not enough to fully heat the entire house, then additional permits must be requested.

However, despite all the shortcomings, in the end, the residents of the house will significantly improve their living conditions and get rid of discomfort. In addition to all the obvious advantages, autonomous systems have an increased level of security.

The new systems are equipped with alarms for threats and accidents. A variety of tracks a variety of indicators. In the event of a breakdown, the backup boiler and additional pumps are activated.

Classification and features of rooftop boilers

If we talk about heating one particular house, then one of the best options the location of the boiler house with a decentralized system is flat roof. The text of the SNiP describes in detail all the permitted types of boiler houses. In technical documents Special attention is given to the requirements for heating equipment intended for installation on the floor.

The operation and installation of heating systems is negotiated separately for two types of structures: built-in and block-modular. Separate requirements, specifications and limitations apply to each option. Also, these two types of boiler rooms have their own characteristics: advantages and disadvantages.

According to the rules, it is unacceptable to install heating equipment directly above residential premises. This means that a technical floor should be provided in an apartment building.

Speaking about the advantages of installing an autonomous boiler room on the roof, the following should be highlighted:

• There is no need to purchase a plot for a boiler room near the house;
• There are no difficulties associated with the calculation of the structure and the conduct of chimneys;
• The task is greatly facilitated;
• Rooftop boilers have no restrictions on the type of fuel, and the use of gas is one of the most profitable options.

The combination of advantages of installing the considered structure on roofs determines the high frequency of using this solution when planning autonomous heating.

Mounting a boiler room on the roof is only advisable if all the requirements and restrictions described in SNiP and PPB are taken into account. Let us further consider each of the available types of rooftop autonomous boiler room.

Block-modular boiler houses

Block or modular boiler rooms are compact in size and occupy small area. Special blocks are brought to the site on the roof of the house, which are then combined into a finished and workable structure. Each element of the structure is completed at the factory and equipped with all the necessary equipment, which is connected to a common system.

After assembly, the thermal station is ready for operation. All necessary equipment is provided by the manufacturer and mounted in the module. It also provides for the availability of separate rooms for staff.

Modern rooftop boilers operate all year round in automatic mode and do not require constant monitoring and the presence of personnel. Therefore, the heat supply is carried out without interruptions.

All equipment is selected according to the required technical specifications and complies with the standards. Blocks are usually equipped with high-quality insulation and a reliable ventilation system.

They may also be attractive appearance And unusual design. During installation, the main task of specialists is to correct connection all nodes and in checking the health of all elements.

Designers and engineers foresee the future installation of a boiler room for gas equipment on the roofs multi-storey buildings. They minimize the weight and dimensions of the frame of the building. Usually, professionals assemble a boiler room in a few working days.

Installation of a block-modular roof boiler consists of several stages. First of all, it is necessary to conduct an examination, which will determine the bearing capacity of the building and the necessary procedures for its increase. If it turns out that it is necessary to strengthen the structure, then these procedures are carried out first.

Then a platform is installed that will rest on the load-bearing walls of the building. This is necessary for the stability of the block. The next step is the creation of a fire-resistant coating under the gas boiler.

Usually, a layer of concrete is poured to solve this problem. You should also ensure safety by installing railings around the perimeter of the roof. Sometimes procedures are needed to improve sound insulation.

Block gas boilers have a complete factory set. Manufacturers give a guarantee of quality. The blocks are sent to the roof almost ready for launch and are assembled in a short time

Block boiler rooms are suitable for installation in buildings where there was originally centralized heating. However, for their arrangement, it is necessary to purchase equipment with acceptable technical conditions and have a project.

Built-in boiler room on the roof of the house

The layout of such boiler houses fits into the design documents in advance. Even at the design stage, each element of the built-in rooftop boiler is described in detail. Engineers calculate many different indicators and, based on the calculations, design a safe and efficient heating system.

Such indicators include the value of the load on the walls, the level of fire safety, the required boiler power, and others. It is much easier and cheaper to carry out these calculations at the design stage than to remake a centralized system into an autonomous one.

Simultaneously with the construction of the building, a number of activities are carried out. These include:

• providing sound insulation and suppression of noise emitted by heating equipment;
• protection of the boiler room from vibrations;
• providing protection against ignition, explosions and gas leaks.

Carrying out these procedures at the construction stage increases their effectiveness. Most of the houses were built for a centralized heating system, and only in the last 5-10 years the projects provide for built-in boilers.

Stationary gas boilers are built from materials similar to those from which the building is built. For these purposes, prefabricated sandwich structures or various reinforced concrete blanks are used.

Experienced engineers are engaged in the design of built-in boiler rooms. This is due to the need to comply with safety standards and legal regulations.

The advantages of such boiler houses include the absence of the need to spend cash and time for capital construction. Also, the customer acquires a ready-made, proven and adjusted design, which will heat the residents of the house for many years.

Thanks to modern developments, it is possible to almost completely automate control. This allows you to have a minimum number of service personnel. The environmental friendliness of the built-in gas boilers is ensured modern systems filtration.

Integrated or built-in boilers are usually installed within a few days, which is very beneficial for the developer.

The device of an autonomous boiler room

Residents do not always buy a ready-made block boiler house. In some cases, the assistance of specialists in the assembly of an individual system is required.

The arrangement of a gas boiler room plays a crucial role in its efficient functioning. It is necessary to allocate a separate area on the roof. There should be no flammable materials around the site.

Domestic boilers are less popular due to the fact that they offer users a low level of autonomy and automation. Experts advise purchasing equipment from European manufacturers

For safety reasons, boiler rooms do not have more than two boilers: the main and the backup. Boilers are usually installed in the center of the room. This makes it easier to approach the equipment for systematic maintenance and repair.

Walls, and with them entrance doors, sheathed with non-combustible materials, for example, steel sheets. The floors are poured concrete screed, then a non-combustible non-slip coating is placed on top of it.

The principle of operation of an autonomous gas boiler is to process natural gas. Thanks to automatic installations, uninterrupted fuel supply is ensured. The boiler room protection system shuts off the gas supply if the sensors detect a leak or breakdown.

Key components of the boiler room

The operation of an autonomous boiler room is ensured by the presence of the following elements:

• Gas boilers providing heating;
• Central gas pipeline supplying gas to the system;
• Ventilation system and chimney that removes gas combustion products;
• Cold water and electricity supply system;
• Security system with a number of instruments and sensors measuring various indicators;
• Built-in automation.

For heating an apartment building, the power of the wall-mounted unit is not enough, therefore, in this situation, floor-standing units are used. gas boilers. Single-circuit boilers provide only heating of the coolant for its delivery to the radiators. When choosing the right equipment, you should focus on the power of the boiler. Also pay attention to the availability of licenses and registrations. The boiler must comply with the operating conditions in your area

The boiler can be with closed and open combustion chamber. For an open type, it is necessary to carry out a smoke channel. And closed-type boilers are equipped.

Thanks to modern technologies the possibility of almost complete remote control heating system while maintaining high level security.

The benefits of remote control include:

• Ability to customize individual temperature regime for each apartment;
• Availability of a warning system about the values ​​of the main indicators of equipment operation;
• Innovative weather control system.

Modern smart boilers have outdoor sensors that measure the temperature outside the home. If the air temperature drops, the boiler automatically starts to increase the temperature of the water in the system and vice versa.

What needs to be considered?

Before arranging an autonomous boiler room, a number of factors must be taken into account. If a single-circuit gas boiler is purchased, then to supply hot water, you will need to install a storage type of water heater - a boiler.

For an extensive system of an apartment building, a distribution manifold will definitely be required. Thanks to this device, constant pressure and temperature will be maintained in all circuits. Together with the collector, hydraulic arrows are also installed.

When the water in the system heats up, it expands. In order to maintain a constant pressure and compensate for expansion processes, a .

The regulations require different minimum chimney heights above the highest point of the roof. When calculating this indicator, the power of the boiler and the structures located on the roof are taken into account

It is important to consider the layout of the chimney to remove the products of gas decomposition. To ensure safety, a mechanical or automatic air vent is installed. Before the heating system, it is necessary to install a make-up tap.

If automation is built into the system, then the need for human service of the system will be reduced to scheduled checks of the system's performance.

Installing an autonomous gas boiler house has a number of nuances and difficulties. However, this version of the heating system for an apartment building has a number of comparative advantages in comparison with a centralized system.

The main problems that developers and future residents will have to face are related to obtaining permits from the administration and the gas industry for the construction of a gas boiler house.

It takes time and requires certain resources. Residents of houses with central heating will face even greater problems. First of all, they will have to get an agreement to turn off the old systems and get specifications for the installation of new ones. It is far from always that public utilities meet halfway on such issues.

Conclusions and useful video on the topic

Overview of the roof boiler TDK "New City":

The installation of a gas-fired boiler house in Svetloye resulted in significant cost savings:

The acquisition of block boiler houses is one of the most profitable options for developers. Their delivery and installation takes a short period of time, and the prices for equipment are reasonable. This allows you not to spend a lot of time on this issue.

Residents who decide to install autonomous heating protect themselves in the future from the shortcomings of centralized systems, guarantee themselves continuous heating and hot water supply all year round.

Please write comments in the block below, post photos on the topic of the article, ask questions. Tell us about your experience in the construction and / or operation of an autonomous gas boiler house in a high-rise building. It is possible that your advice will be extremely useful to site visitors.

Installing a gas rooftop boiler in an apartment building provides significant cost savings by reducing heating and utility bills by approximately 30%. At the same time, the structure must comply with the building requirements set forth in “Design standards. Boiler plants», as well as a specially released addendum P1-03 .

Types and arrangement of roof boilers

The standards separately stipulate the possibility of operating a built-in and block-modular boiler house. 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 operation of heating equipment is increased.

Block-modular roof boiler rooms

Installation includes the following steps:

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

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

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

Built-in rooftop boilers

It is much easier to make and coordinate the project of 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 extremely rare, mainly in new houses, the construction of which began in the last 5 years.

Boilers for rooftop boilers

Domestic thermal units, for all their merits, do not differ in autonomy. Therefore, the choice mainly falls on the products of Italian, German and other European manufacturers:

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

When choosing a suitable boiler, they are guided by thermal power, the presence of registration and license issued by Rostekhnadzor, adaptation to domestic features operation and cost.

Design standards for gas-fired rooftop boilers

The basic requirements and design standards for rooftop boilers have remained the same and include the following provisions:

• It is not allowed to install a technical room directly on the ceiling of living rooms.
• The adjoining of the boiler room to the walls of residential premises is prohibited.
• Operation of a fully autonomous station is allowed.
• It is mandatory to have an alarm and a system that gives a signal to turn off in case of emergency.

The minimum height of the chimney pipes above the roof is at least 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 the adjacent buildings and other technical characteristics.

These SNiPs cover four important areas of design, requirements for: location, gas supply, power supply and compliance with the PPB.

Requirements for roofs for boiler rooms

• Public buildings- it is forbidden to place a built-in boiler room above the premises with the intensity of simultaneous stay, more than 50 people. Hospitals, polyclinics, sanatoriums, schools, nurseries, etc. fall under the ban.
• apartment buildings- the standards governing the operation of a boiler house in an apartment building indicate a direct ban on the installation of a station that exceeds the total thermal power of 3 MW.
  Power restrictions also affect built-in thermal stations. General rule– a ban on exceeding the thermal power by more than 15% of the total heat demand of the building.

• Height limit- in the old SNiP II-35-76 (designers still refer to it), there is a limit on the height of the building, on which it is allowed to install a roof boiler. The maximum height is 26.5 m, which is equivalent to a 9-storey building. In the current joint ventures, height restrictions are not indicated at all.
• Size restrictions- the boiler room should not exceed the dimensions 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 the increase in the weight load on the load-bearing walls.
• Location restrictions- roof gas boilers for apartment buildings, are installed only after an examination and implementation of measures to strengthen the supporting structures. Installation on floor slabs, placement next to the walls of residential premises is not allowed.

Gas supply to the boiler house located on the roof

• The pressure in the line must not exceed 5 kPa.
• The gas pipeline is carried out along outer wall building. It is not allowed to cut into the pipe to connect other sources of gas consumption.
• The laying of the gas pipeline on the roof and walls must be open. It is not allowed to close the main pipeline with gratings, removable and non-removable structures.
• To regulate the flow and turn off the gas supply, shut-off and control valves are installed at the inlet of the main to the house and the connection of each heat generator. At the installation site of the reinforcement, the presence of artificial lighting is mandatory.
• 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 scheme is used, providing for a mixing unit for heat release. For each facade or area of ​​the building, a separate thermal arrow is installed. In a rooftop boiler room, the heat carrier temperature should not exceed 115°C.
• DHW - for hot water supply, installation of a separate heat generator is allowed. Hot water supply is carried out in a closed circuit, through heat exchangers.

Power supply for the boiler room on the roof

The following measures are envisaged:

• Lightning protection - the project is being 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 fixtures with a metal protective mesh.
• The need for a backup power supply for the rooftop boiler is foreseen. In the event of a power outage, it is necessary to provide power to turn on the backup circulation pump and ensure the operability of automation, alarm and notification systems.
• To disconnect the boiler from the power supply, a switchboard is installed, located outside the premises of the thermal station.

Roof fire extinguishing

"... A building with a height of more than 12 m, not equipped with an internal fire water supply for supplying water for fire extinguishing, having a roof boiler room, must be equipped with a "dry pipe" with an output 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-fighting requirements for rooms for placing a roof gas boiler in an apartment building, including the following recommendations:

All norms of the requirement are aimed at minimizing the occurrence of possible emergencies, therefore, in some cases, local authorities supervisors may recommend additional security 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 the rooftop boiler house

1. Preparation of project documentation and approval.
2. Carrying out technical work on the installation and arrangement of a thermal power plant.

• Measures aimed at damping and soundproofing - it is not allowed that noise pollution exceeds 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. work on the arrangement of noise-absorbing and vibration-reducing barriers.
• Organization and implementation of work on maintenance- the staff undergoes special training and receives the appropriate license. After installing the boiler equipment, it is allowed to conclude an agreement with residents for the maintenance of boilers and related equipment.

The preparation of project 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.

rooftop boiler cost

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

The full cost, including the preparation of project documentation and obtaining all necessary approvals, costs 5-10 million rubles, depending on the number of residents and the selected capacity of heating equipment.

Roof boiler - pros and cons

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

Benefits of a rooftop boiler

• The supply of heat carrier and hot water in a multi-storey building with a roof gas boiler is carried out directly to the building on which the station is installed. This leads to a decrease in heat loss during the delivery of the coolant from the boiler house to the consumer. No need to pay for heat losses that exist with centralized city heating.
• Due to the full automation of the heating process, the fee for the maintenance of the boiler room is reduced to a minimum. If necessary, an agreement is concluded with a contractor who simultaneously serves several thermal power plants.
• The heating season starts when it is needed, and does not equate to a specific date.
• High safety - the gas boiler house is arranged in such a way as to ensure maximum safety of operation. The prevention of emergencies is facilitated by the many requirements and approvals that boiler equipment goes through before it is put into operation.

Disadvantages of rooftop boilers

• Installation restrictions - for a roof boiler room, the number of storeys of the house is allowed, not higher than 9 standard floors. As mentioned above, this requirement can be challenged, but this is not always possible in practice.
• Vibration problems - powerful circulation pumps operate in the boiler room, turbines are located in the boiler, emitting high intensity noise and vibration. And this significant shortcomings for tenants on the top floor.
• High cost - production and purchase of project documentation, sound insulation work, etc., will cost 5-10 million rubles. To save money, order a turnkey boiler room.
• Disadvantages of rooftop boilers at the regulatory level - as already mentioned, many officials in design organizations, as the main requirements, cite outdated building codes. To "persuade" them, it may be necessary to repeatedly apply to the courts. It all depends on the region of paperwork and the officials themselves.
