Boiler houses in a private house

In a private house you need boiler houses. But to do everything correctly, it is necessary to take into account the basic requirements for the gas boiler room, the scheme and the standards of the area of ​​the room for gas boilers on the bottom. We also have to pay attention to the main types of buildings.


Not just a disadvantage, and straight and terrible danger is that the boiler room in a private house can be a source of carbon monoxide gas. Of course, all the necessary structural and performing measures are taken, protection machines are used, but the full guarantee is impossible to give. If you put a boiler room in a separate building (by the way, it is recommended), the total cost of work will be very large. Not all people can pay the required amount.

Maintaining the entire complex in workable form is also not so simple and cheap, as it seems at first. Calling specialists will have to do more often than I would like to. Not all problems can be eliminated with your own hands. However, it is worth noting the advantages, due to which the massive passion for homemade boiler rooms occurred:

  • autonomy in relation to monopoly thermal companies;
  • reduction of heat losses (even with the perfect condition of the heating mains, which occurs infrequently, the loss is 30% of the initially generated heat);
  • Easy tuning is ensured (depending on the weather, even from well-being and health status).

What documents are needed?

Just to build a boiler room in a private house can not – need to make up quite a lot of special permits. Necessarily state expertise. All design materials are subject to her, including the results of engineering surveys. The final result is the conclusion on the compliance or non-compliance of the project by regulatory terms. The official permission has become a prerequisite in 1997, since then a division of hazard classes has occurred. Without a resolution act, boiler rooms cannot be commissioned, which:

  • use natural or liquefied gas;
  • produce not only heat, but also hot water;
  • contain at least some parts of the equipment, calculated on the temperature of over 250 °;
  • contain at least some parts of the equipment designed for pressure above 1.6 MPa.

Commissioning is issued by the appropriate act. It is invalid if there are no signatures of all participants in the technical commission and an employee of Rostechnadzor.

Build and operate boilers allowed if the land belongs to ownership. As a last resort, the construction of heat generating systems on the areas rented for a long time.

Types of technical equipment must be recorded in technical supervision bodies (which is also confirmed by the marks on them). The package of documents together with the statement goes to the territorial inspection, and after the departure check, give a license.

Primary requirements

A number of requirements are presented to the boiler house.

To safety

When designing boiler houses, many positions refers to the room where the necessary equipment is located. Boilers and other devices must be separated from home and from other residential spaces. Since any type of fuel, including electric heating, potentially entails certain hazards, it is impossible to call such norms by bureaucratic arbitration. It is necessary to carefully check what specifically the standard is valid in a certain case. Boiler rooms, created before July 1, 2003, must meet the SNiP 2 provisions.04.08-87. All that is built or commissioned after this date is subordinate to SNIP 42-01-2002.

The main points of the Standard must necessarily know the Customer himself – after all, he needs to control whether the project has been drawn up qualitatively, the engineers of a specialized organization competently approached their work. Bought equipment also immediately checked with the designated design standards. So, The minimum area for the gas boiler for the project is normalized, but above that clearly defined that:

  • With heat power, no more than 60 kW can be positioned in the kitchen (if enhanced ventilation is organized);
  • with thermal power from 61 to 149 kW, a separate room is required (basements and basements are allowed);
  • When developing 150 kW of heat and need to be needed strictly separate building.

With regard to the total volume of home boiler houses, it is as follows:

  • when working out no more than 29 kW of heat – from 7.5 m 3;
  • When developing 30-59 kW – at least 13.5 m 3;
  • Upon receipt of 60-200 kW heat and more required to create a room with a volume of 15 m 3 and more.

Important: For a gas boiler, unlike other sources of heat, in any case, the minimum volume of the room should be 15 3, while the height of the walls (in any part of the building) is less than 2.5 m.

All boiler rooms in private dwellings must have the highest possible natural lighting. The glazing area is rigidly fixed in the standards: 1 m 3 of the internal volume of the boiler room should be provided for at least 0.03 m 2 glasses (excluding frame, other structures). In any case, only swing, open windows disclosed. Without the flow of water and the organization of the sewer run, the boiler room cannot be used.

It is often a statement that building a boiler room in a wooden (both frame, and built of logs) house is unsafe. This is motivated by a certain emergency fire hazard of such buildings. In fact, the risk has long been almost absent – it is eliminated both special wood processing, and special design, technological solutions. In addition, both stone and bricks, and in aerated concrete boilers there will still be a lot of combustible materials. To the boiler you need to ensure unobstructed continuous access.

The adjoining of the chimney and all wooden structures should be performed with fire gap. At the same time, asbestos and other protective substances are used, which prevent fire. Wooden walls are subject to shielding. But even such requirements are not sufficient – it is necessary to provide a comprehensive fire extinguishing system and alerts. Its installation must be performed by professionals, it should also be entrusted with periodic surveys.

The race for the beautiful design should also be carried out in strict accordance with the security requirements. So, it is allowed to finish with plasterboard under the condition of subsequent coating with plaster and / or water-emulsion paints. On the floor put a tile or metal sheets. They are worth painting a durable, resistant to high paint temperature. Instead of plasterboard wall, it is possible to make cement-chip and acid-fibrous blocks.

The entire design of the walls, including finishing, should be designed for fire resistance at least 45 minutes. If this indicator reaches at least 60 minutes, it will be even better.

Plastering walls can be only safe in firing plan. All fire-resistant plaster mixes have a gray color. Additionally decorate them with heat-resistant water-based paints. The choice between wooden, plastic and aluminum constructions of windows remains at the discretion of the owner. However, it is necessary to understand that during the combustion of PVCs, toxic substances appear.

The planning of the boiler room in no case should be arbitrary, there are very clear and unequivocal rules. So, boilers, buffer tanks and other heated equipment are installed strictly as prescribed by the manufacturer. Wall heat generators hang highs at a height of 1.5-1.8 m (if it is more, to use the technique is uncomfortable and unsafe). Before the front sides of the heating devices should remain at least 1 m. Free space. Recommended gap between their walls and capital walls or surrounding items – 0.03 m. In any case, the Plan will have to place the location:

  • boilers themselves;
  • chimneys;
  • external conclusions (pipes);
  • radiators;
  • expansion tanks;
  • connecting pipelines;
  • valves;
  • bypass;
  • cranes of Maevsky and other parts.

Separate topic – Safety of boiler rooms that do not use gas fuel. They are still recommended to form according to the most stringent possible standards. Grounding the electrical boilers and wires must match PUE. Everything should be connected so that there are no mechanical loads on the wires and contacts. As for solid fuel systems, it is recommended:

  • Installation of an inverter in binders with batteries (providing uninterrupted food);
  • the use of heat accumulators;
  • Combination of inverters and thermal batteries.

To ventilation

In addition to the main ventilation facilities, it is necessary to provide for the window or fraamugu in the window. It will provide emergency ventilation during a gas leak or fuel spilling, with carbon monoxide contamination. The influx of air is calculated taking into account the information about its movement obtained by the use of anemometer. The total value of the inflow according to the current SP should be at least the volume of the hourly expense. You can get the necessary information from gas supervision specialists in their region.

Ventilation in boiler houses always make strictly on official projects.

Be sure to seek the tightness of the ventilation channels, as needed – use the sealant. Air swap can occur both outside and inside the building. But it is impossible to supply fiber air through residential premises. Natural ventilation is suitable only for boilers no more than 30 kW, otherwise fans are required.

To chimney

The chimney canal may have a round or rectangular shape. Connecting to smoke trumpets is made using pipes from roofing either supplied in a set of elements. All parts of the chimney outside the building are required to heat insulating. The cross section and the height of the structure are carefully selected according to the boiler parameters. Other requirements:

  • For each boiler should be their chimney;
  • They should not be umbrellas and reflectors;
  • Between the boiler and the connecting nozzle, there is a hole for cleaning;
  • Pipes raise over the highest building in the district.

Description of species

There are several types of boiler.

Built in house

This type of boiler houses is appropriate in the basements of single-storey houses, and on their first floors. The main minus is an insufficient level of security. In addition, many boilers create a lot of noise. To some extent, it is justified by the convenience of using boiler equipment. Most often built-in complexes are located in kitchens and corridors. We must certainly be a separate way out of the outside and a number of fire prevention partitions.

In an extension

Attached to the residential house (located, for example, in the garage) boiler room will arrange those who do not need especially high power. Boiler room will be cozy and will save money. The door will have to sway with leaf iron and / or asbestos. An additional noise insulation is carried out with residential premises. It is not prescribed by standards, but needed.

From the attached boiler room should always be out out. In some cases, there is no passage to the house itself. Only experienced engineers can understand these restrictions. Thermal capacity of the equipment should not be selected with a margin, but only in full compliance with the needs of residents. Regulations apply not only to heating equipment, but also to methods of heat supply of the building itself from its extension.

Detached building

Such buildings are trying to close as much as possible to residential buildings. A variety of technical communications are used for communication between them. In individual boilers it will be possible to have any heating boilers, use any types of fuel. It is allowed to use boilers of almost unlimited power. Heat mains are used to supply heat in the dwelling.


This option is optimal when it is impossible to put a boiler room inside the house, it will not be possible to build a separate building. Such designs are assembled on the basis of factory components and mounted quite quickly. The length of the special container is a maximum of 2.5 m. Inside the steel structure insulate. Multilayer heat insulated pipes are usually included in the supply set. Block-modular boiler rooms can eat:

  • liquefied gas;
  • coal;
  • diesel combustible;
  • firewood;
  • Natural gas.

Overview of elements

The key element in the arrangement of the boiler room is the heating boiler.

If you plan to spend water on domestic needs, you have to put a boiler.

This device is very cumbersome, and if there is no need for it, to buy such a device inexpedient. But the expansion tank, allowing to align the pressure, is very useful. In addition to it, in the heating systems with a large number of contours, a distribution collector must be present. In addition to these elements and chimels, it is necessary:

  • a pump that provides circulation;
  • security group;
  • a complex of pipes with locking reinforcement;
  • Machine control of gaspace.

Tips for mounting

The diagram of the heating device in each private house is individual – and yet there are clear principles and criteria wearing more or less universal character. The order of the strapping of boilers of heating and hot water supply includes with their own hands, first of all, dividing on an open and closed group. In the open version, the heating boiler is set below all other components. Expansion tank raise as high as possible: it is the height difference between them that determines the overall efficiency of all equipment.

Open scheme prepare the easiest way. In addition, it is non-volatile, which is very important for remote seats and for districts where there are frequencies in power supply. But it is necessary to understand that the continuous contact of the heat carrier with atmospheric air leads to the inevitably clogged by air bubbles. The coolant will circulate slowly and accelerate its current due to structural circuits. If these moments are fundamental, and if there is a desire to reduce the coolant consumption, it will be more correct to make heating by closed scheme.

If the boiler room is located in an extension, then it should be adjusted to a solid segment of the wall. At the same time, to the nearest window or door should be left at least 1 m of free space. The construction itself is made of fire-resistant material with a guaranteed burning resistance not lower than 45 minutes. Wall-mounted boilers fasten only on the walls of non-aggravated materials. Carefully follow that all other walls were at least 0.1 m.

The best screen for the boiler is a steel stainless sheet, which is still put asbestos.

If powerful (200 kW and stronger) are used) boilers, it is necessary to prepare for them a separate foundation. The difference between the height of this foundation and the floor height cannot exceed 0.15 m. When gas fuel is planned, it is planned to install the device for a tube, emergency gas in a critical situation. The furnaces are equipped with unoccupied or poorly fortified doors: when the explosion throws out, it throws out, and it reduces the danger of destruction of the whole building.

When the boiler room is mounted, built into the house itself, it is allowed to install and thoroughly fortified doors. However, they have another requirement to: restrain the fire at least ¼ hour. To improve ventilation, in any case, a hole closed with a grid is made in the lower third of the door. The entire volume of walls from the inside is separated by non-aggravated materials. This must be performed as soon as the installation of the boiler and its connection to communications.

Bashed on the wall of boilers more powerful 60 kW completely unacceptable.

Important and number of contours. If you plan to restrict ourselves to heating, it is quite reasonable to choose a single-circuit boiler. To note: it can be used for hot water, but only in a bundle with a boiler. Installation of the boiler justified at 2 conditions: a lot of hot water is consumed and there is a lot of free space. Otherwise, it will be more correct to order a two-round boiler.

Ventilation communications are mounted in the opposite of the boiler wall. In the ventilation pipe must be mounted mesh and damper. In boiler houses, located in a separate room, you will have to do the ventilation channel in the door with a louvred grid.

Each kilowatt of thermal power should have 8 cm 3 volume of ventilation passage. But if the air comes from the inside of the house, this indicator is 30 cm 3.
