The heating piping system is traditionally laid under the floor or along the walls. But such common options for carrying out installation work are no longer always possible. In this situation, modern roof boiler houses come to the rescue. It should immediately be noted that the presented method of laying pipes is quite complex. On the other hand, it has significant advantages. Most often, such boiler rooms are installed in industrial enterprises, where it is impossible to rely on more familiar types of communications.
Main characteristics
The presented heating options assume the placement of boilers in the form of independent IHP. They may well be located on the upper or roof floors of the building. This is where such a specific name came from.
Key advantages of the system:
- lack of mandatory land allotment;
- easy access to communications;
- easy technical inspection;
- increased level of security.
Even if the fuel supply is carried out in emergency mode, the likelihood that smoke will appear inside the room is practically reduced to zero. The same can be safely said about an open flame.
Additionally, experts note the fact that such a boiler house is also characterized by environmental safety. In this regard, other options clearly cannot compete. The secret is that gases located on the roof have greater access to the atmosphere. As a result, the process of their removal is significantly simplified.
Distinctive qualities
It should be noted the high productivity of rooftop boiler houses. Today, manufacturers no longer produce devices that are too weak in terms of power and are suitable for a limited number of buildings. Modern roof boiler houses can provide heat even to multi-storey residential buildings.
Cost-effectiveness is also one of the distinctive parameters of this equipment. Due to the fact that such boiler houses operate on gas, their fuel consumption is far from the most significant. In addition, its cost is not very high. Any modern model of the described devices clearly meets the world's economic standards.
Ease of operation and low cost are additional advantages of the equipment. Average users will be able to carry out basic preventive actions on their own. As a result, they save money not only when purchasing a device, but also during its further maintenance and even repair.
In general, it can be noted that the choice and installation of a rooftop boiler room is a very profitable solution. Such equipment eliminates a lot of problems. First of all, this is due to excellent technical parameters. A significant range of models will also appeal to consumers.
Most often, the power of a gas roof modular boiler house varies from 0.5 to 3 MW
Block-modular roof boiler houses are manufactured individually, according to the customer’s required parameters. Assembly and testing are carried out in the factory, and the finished product receives a guarantee from the manufacturer. The time required for installation, preparation and commissioning is minimal.
Installation on technical floor floor slabs is optimal. In the absence of a technical floor, special attention must be paid to the fact that the modular boiler room should not be installed directly above the living quarters. It is also necessary to provide a drainage system and waterproofing (at least 10 cm thick).
The installation of gas roof boiler rooms on buildings above 26.5 m must be additionally coordinated with the fire services.
Thermal schedules are observed automatically; in emergency situations, the gas supply is stopped and service personnel are called to the site.

The individual heating point (IHP) of a modular roof boiler house can be located separately from it. For example, in the basement or on the ground floor of a building. A heating point is a set of devices that serve as a kind of intermediary between the heat consumer and the installation that produces it. In an apartment building, the heating unit is responsible for distributing hot water between the heating, hot water supply and ventilation heat supply systems.
ITP monitors and regulates coolant parameters and supports protection against emergency exceeding of its parameters. Heat meters and other flow metering devices can also be installed in the ITP.
A few words about the cons
Despite the presence of such noticeable advantages, roof boiler houses have certain disadvantages. Among them, we can highlight the need to use the most advanced equipment designed for the installation of heating system components. In this case, you still need to strictly adhere to the rules and requirements. These are restrictions regarding the weight of the equipment, but the boiler is the main component of the total mass.
As practice shows, copper heat exchangers are of the highest quality. An additional complexity lies in the fact that the presented heating system simply cannot do without automatic monitoring and control. On the other hand, it should be noted that the described boiler houses can safely be called an achievement in the field of energy supply for various objects. Because of this, it is logical to assume that in the coming years this equipment will completely displace the remaining boiler room options from the market.
Standards, design and requirements for the operation of boiler houses
Roof boiler rooms for apartment buildings are a modern solution to the problem of designing autonomous heating without connection to a centralized gas main. After all, modern building construction sometimes requires standards that cannot be implemented. Heat loss, thanks to this design of heating for apartment buildings, is low, so installing a rooftop boiler room is even the norm for an economical option.
The popularity of rooftop gas boiler houses is growing every day, since thanks to this heating design, the costs of land allocation will disappear, and there will be no need to design a heating main. And even the temperature can be set more accurately.
What other advantages does designing rooftop boiler houses have? Are there any disadvantages to using it for apartment buildings? Are there safety regulations that must be followed when designing boiler rooms on rooftops?
The requirements and standards for the design and installation of this structure are not significant at all, but still, they exist. Since safety is the main thing in our world, and first of all we need to take care of it.
Rice. 4 Autonomous boiler houses
So what standards, precautions and operational measures need to be taken to ensure that the rooftop boiler room works long and well?
- It is necessary to check the supply and exhaust valves, since thanks to them the boiler room is ventilated.
- It is necessary to install sensors, the design of which controls the process of operation of the gas device and which are triggered directly during the lightest fires. These are necessary to prevent a fire or explosion from occurring. It is advisable that when designing rooftop installations, a function is installed that automatically extinguishes the first signs of a fire.
- It is also necessary to install a gas-insulating flange, which can shut down the entire system at the first sign of a fire.
- On the roofs of multi-storey buildings, it is necessary to install an alarm system that displays and transmits light and sound signals in case of fire.
- The height of the chimney should be much higher than the height of the roof boiler room. The minimum difference is 2 m. Each gas boiler in the house must have a separate chimney, but it is imperative that they be the same height. What the distance between them will be does not matter.
- Roof-top gas units must operate from separate electricity, that is, have a separate branch of the electrical network. The voltage in the house may be different, so you should not take risks with electricity, since due to a failure in the electrical network in the house, problems may arise in the operation of the entire heating system. A diesel generator may be suitable as an autonomous power source.
- This equipment cannot be installed directly above apartments in houses. The presence of a technical floor is a prerequisite for installing a roof boiler room. The floor on which the rooftop gas units will stand must be made of reinforced concrete slabs.
- Do not forget that this heating equipment makes a lot of noise, therefore, in order to be able to install roof-top boiler rooms in multi-storey buildings, it is necessary to meet special requirements in accordance with sound insulation standards in premises.
- The boiler room must have windows and doors that lead directly to the roof. A separate elevator is required, as it will only be used for firefighters. It is also necessary to design a service exit. The boiler room must be illuminated according to the standards (0.03 sq. m/1 m³).
- You should also not forget about the service personnel - there should be a separate safe exit for them during the design.
Rice. 5 Gas equipment on the roof
After designing and installing a gas roof boiler room, it is necessary to look after it, that is, perform maintenance. Maintenance personnel can also handle this. But we also shouldn’t forget about gas service representatives. They must check this equipment at least once a year.
Relevance of roof boiler houses
Thanks to a number of positive aspects, the described heating equipment may well be useful in a wide variety of situations and operating conditions. Among them, first of all, we should highlight the lack of free space in the immediate vicinity of the building. In this case, traditional heating systems cannot be installed.
In today's conditions of active and dense urban development, the relevance of the use of roof-top boiler houses is noticeably increasing. Moreover, if such systems are used for low-rise construction, the final building can be made completely autonomous. As a result, rooftop boiler houses are already very common, and not only in large cities.

Advantages and disadvantages of this equipment for heating apartment buildings
When considering all the disadvantages and advantages of this unit, you will notice that, of course, there are more advantages. Construction companies choose rooftop units for installation in apartment buildings. And all because it is both economical and reasonable, and they work in accordance with all established standards. This is especially convenient when either there is no centralized gas main or it is abandoned during construction.
And so, the main advantages of this equipment:
- Roof units can do without a separate place for themselves. That is, it is not necessary for them to install an additional building. A roof is also suitable for operating gas equipment in a multi-storey building. The water frame or collector may be located away from the design of the roof boiler room (attic, basement).
- Heat loss is very low when these units operate. There is no longer a need to install heating mains, and thanks to this, much less money will be spent on equipment maintenance.
- Costs for connecting to centralized communications are also reduced. And everyone knows that you have to pay a tidy sum for this in our time.
- The design of roof boiler houses has no more requirements. Forced ventilation and installation of chimneys will not be required. SNiP makes it possible for such huge equipment to heat buildings up to 30 m high.
- When designing these equipment in apartment buildings, all standards will be observed and, according to SNiP, the system can be fully automated. The operator will not even be hired for a whole working day, but only for a couple of hours. Thanks to SNiP, the standards for designing rooftop boiler houses will make it possible to install sensors on them that will monitor the temperature outside and turn on the required heating level themselves.
- The good thing is that people will no longer have to adapt to the standards established in the country (there is no heating in the summer). The unit can also operate in the summer if necessary. Who can service a rooftop boiler room? Yes, simple staff who look after her all year round. You won't even need to call specialists. This equipment is easy to use.
For final heat consumers
Advantages of apartment heating:
- Ability to regulate the temperature in the apartment;
- With constant attention to gas equipment, compliance with all operating rules and clear accounting, savings are possible.
Disadvantages of apartment heating:
- High costs for repairing gas equipment or replacing the boiler after the warranty period expires;
- The need for constant monitoring of the serviceability of the gas equipment used;
- The need to independently organize repair and maintenance work related to the operation of gas equipment and chimneys;
- Unheated driveways and basements;
- In the absence of permanently living neighbors, their apartments are not heated, and accordingly increased heat loss;
- Increased risks of accidents due to improper operation of equipment (by any of the residents).
For the developer
Among the advantages of apartment-by-apartment fencing, we can highlight the simplification of the delivery of a residential property during commissioning.
However, certain difficulties arise when selecting boilers due to significant differences in the water supply of heated water. There is also a need to install a chimney system.
Environmental safety speaks in favor of a modular boiler room. The removal of combustion products is easier compared to flues, because The boiler room is located on the roof and gases have greater access to the open atmosphere. In addition, it becomes possible to attract a contractor to supply a turnkey boiler room.
One of the disadvantages of a modular boiler room is that it is a rather troublesome boiler room procedure, which is an integral element of the delivery of a house.
