The question of where the boiler house can be located in a private house, what requirements are placed on the premises and the layout of the equipment, should be decided at the design stage. Another thing is that in existing houses there is a need to install new heat generators operating on different types fuel, and the design of the boiler house is already outdated. To understand how to make the arrangement of the furnace in a new way, you should study the requirements for the premises imposed by regulatory documents (SNiP).
Types of heating equipment
To perform the installation of a boiler house in a private cottage in accordance with the regulations, you first need to select the type of heat source and on which energy source it is planned to work:
- natural or liquefied gas;
- varieties solid fuel(firewood, coal, pellets, briquettes);
- diesel fuel, waste oil;
- electricity.
Various combinations are also possible, for example, solid fuel boiler with gas and electric. The arrangement and placement of thermal power plants of a gas boiler house in a private house is carried out according to more stringent requirements than the installation of heat generators on electricity and solid fuel. Equipment parameters also play a role - the power and size of the boilers.
About the installation of gas-using installations
The most stringent requirements are imposed on a gas boiler house in a private house, since it is a source of increased fire and explosion hazard. But natural gas heaters are quite reliable and equipped with safety automatics. Therefore, for the placement of units, whose parameters in terms of power and dimensions are small, the SNiP standards do not express any special restrictions. Gas boilers with a heating capacity of up to 60 kW are installed in compliance with the following standards:
- The unit may be installed in a separate room on any floor, including the basement or basement. It is also allowed to install in the kitchen in the presence of ventilation and compliance with the conditions for its area and ceiling height.
- The kitchen, where the equipment for heating the house is located, must have a height of at least 2.5 m. The total volume of the kitchen is 15 m³ + 0.2 m³ per 1 kW of boiler power. For the organization of supply and exhaust ventilation, a window (exhaust) and a supply grille with a passage area of at least 0.025 m², built into the entrance doors, are required.
- The SNiP imposes the same restrictions on other separate premises where it is planned to supply gas-using equipment with a capacity of up to 60 kW.
- The mandatory requirements for a gas boiler include the organization of air exchange in the required amount. The inflow should be enough to burn gas in the boiler and to renew the air in the room 3 times in 1 hour.
- To burn liquefied gas, ventilation is equipped taking into account the fact that propane is heavier than air. Therefore, an exhaust hole with a grate is made in the lower zone, above the floor.
If equipment with a capacity of up to 150 kW is used for heating, then it cannot be installed in the kitchen; a gas boiler room is needed in a separate room on any floor. Restriction on the volume of the furnace - at least 15 m³, height - not lower than 2.5 m. Additional requirement concerns the walls of the boiler room separating it from neighboring rooms: they must have a fire resistance limit of 45 minutes, that is, they must be built from non-combustible materials. Wall decoration should also not contribute to the spread of open flames.
The requirements for supply and exhaust ventilation remain unchanged for all gas-using installations: 3-fold air exchange plus supply air for fuel combustion.
Windows in the boiler room must be made of a certain area in order to provide standard natural light. The glazing area must be at least 0.03 m² for each cubic meter of the furnace volume. In addition, the windows in the boiler room play the role of easily dropped structures in case of a possible explosion of the gas-air mixture.
All of the above requirements must also be observed when placing heating equipment, whose total power reaches 350 kW. One amendment: such powerful units are allowed to be installed only in a separate room on the first or basement floor. From there, direct access to the street is made with the installation of type 3 fire doors.
Accommodation in the annex and in a separate building
Heat generators of any capacity, burning all types of fuel, are allowed to be installed in premises attached to the house or in separate buildings (modules). Dimensions, ventilation and lighting requirements are listed above. Although a 3-fold air exchange is not required for the operation of a solid fuel boiler, it should be organized for purely practical reasons. Wood-burning and coal-fired units emit smoke inside during maintenance, and an unpleasant odor spreads from the diesel heat generator.
When building an extension, the following rules must be observed:
- walls and roof - from non-combustible materials with a fire resistance limit of 45 minutes;
- building height - at least 2.5 m, glazing - 0.03 m² per cubic meter of volume;
- it is not allowed to connect the structures of the extension and the walls of a residential building;
- the minimum distance from the attached boiler room to the nearest opening (door or window) is 1 m.
A separate building is built according to the same rules and taking into account the convenient layout of heating equipment with a distance of at least 2 m from the cottage.
Layout of thermal units
The layout of the boilers inside the furnace is developed taking into account the convenience of operation and maintenance, as well as regulatory requirements. They apply to both gas and solid fuel boilers and look like this:
- clearance between the wall and the protruding part of the front part of the boiler - at least 1 m;
- distance between 2 heat generators on any type of fuel installed side by side - 1 m;
- the width of the passage for servicing equipment from the side where it is needed is 0.6 m;
- the passage between 2 boilers standing opposite each other is at least 2 m.
Passages must not be littered or blocked with pipelines and cables suspended below 2 m. Cables can be laid along the floor inside steel pipes, and heat mains - along the walls, but not across the passage. In addition, the requirements for a boiler room in a private cottage require the installation of heavy floor units on their own foundations that are not related to the foundation of the house.
If it is necessary to install 2 floor heat generators, then a common reinforced concrete foundation in the form of a plate. The foundation is supported by soil with a compacted crushed stone cushion, and not a previously poured concrete screed. For the device of the base, part of the old screed will have to be dismantled. The time required for the concrete to harden and the equipment to be ready for installation is 28 days. After installing a solid fuel boiler in front of it on the floor is laid steel sheet size 0.7x1 m.
When installing a wall-mounted heater in the kitchen, it is necessary to isolate the unit from the wall by laying a sheet of metal protruding 10 cm beyond the boiler body. The horizontal section of the chimney pipe from the heat generator to the passage through the wall or ceiling can have no more than 3 turns.
Heating pipelines passing inside the boiler room are recommended to be covered with a heat-insulating layer. Electrical outlets and other electrical appliances must be located in such a way that in the event of an accident or leakage, they will not be exposed to water.
Building codes and regulations provide for a number of strict requirements that apply to gas boiler rooms.
Firstly, heat generating units should be located in separate non-residential premises. It is allowed to place the boiler in the kitchen - regardless of whether it has a gas stove or a gas boiler - but only if the boiler power does not exceed 60 kW. With a heating boiler power of up to 150 kW, for a gas boiler room, you need to choose a separate room on any floor of the building - including in the basement or basement. If the power of the boiler for heating and hot water supply is 150-500 kW, then in this case the boiler room should be located in a separate room on the first, basement or basement floor or in an extension to a residential building.
If the gas heating boiler will be located in the kitchen, then it must comply with the following parameters: ceiling height of at least 2.5 meters, room volume of at least 15 cubic meters. meters plus 0.2 cubic meters. m. for every 1 kW of power of the heating unit. The kitchen should be well ventilated - exhaust ventilation should be organized in it in the amount of three air exchanges and air inflow in excess of the exhaust volume (to maintain gas combustion). On the kitchen window there must be a window, and in the lower part of the door - a grill or a gap for air flow, with an area of \u200b\u200bnot less than 0.025 square meters. m.
If the heating unit with a total power of up to 150 kW is located in a separate room on any floor of the building, then the requirements are as follows:
- ceiling height in the room is not less than 2.5 meters;
- the volume of the room is not less than 15 cubic meters and the free area from the condition of convenient maintenance of the units;
- the boiler room must be protected from neighboring rooms by walls with a fire resistance limit of 0.75 hours and a zero value for the limit of fire propagation along the structure;
- the room should have natural lighting with glazing of at least 0.03 sq.m. for 1 cu. m. premises;
- ventilation of the room: threefold exhaust and inflow exceeding the amount of exhaust by the volume of air required for gas combustion.
If heating equipment with a total thermal power of up to 500 kW is located in a room attached to a residential building, then this extension should be characterized by the following parameters.
The attached boiler room should be located near the blind part of the wall, and the horizontal distance from window or door openings for residential buildings should be 4 meters, and for industrial buildings - at least 2 meters; the minimum vertical distance from the ceiling to the window should be 8 meters.
The wall of the attached premises should not have a connection with the walls of the residential building.
The enclosing walls and structures of the attached premises must have a fire resistance limit of 0.75 hours with a fire spread limit of zero.
- The minimum height of the room is 2.5 m.
The volume and area of the extension should provide convenient maintenance of the equipment (but not less than 15 cubic meters).
The room should be provided with natural lighting with a glazing area of 0.03 sq.m. for 1 cu. m. premises.
A ventilation system with a triple exhaust must be provided in the room, and the inflow must ensure that the exhaust volume is exceeded by the amount of air that is spent on gas combustion.
If a gas boiler room is arranged on the first, basement or basement floor of a building, then a direct exit to the outside should be arranged in it. In addition, the boiler room may have a second exit to utility room equipped with a type 3 fire door.
If liquefied gas is used as fuel, then the placement of gas appliances in the basements and basement floors of buildings is prohibited.
You can order an autonomous boiler room by phone at the ELSO Energogazmontazh company. Design, installation, coordination and service.
Designing a boiler room in a private house belongs to the category of serious issues that must be taken responsibly. In order to successfully complete all the work, it is advisable to study the regulatory documentation, get advice from experts in this field.
In addition, keep in mind the issues of ease of maintenance of the furnace, as well as ease of access to shut-off units. Further in the article, the process of arranging a boiler room in a private house, which complies with generally accepted standards, will be considered.
Primary requirements
It is ideal to start developing a boiler room scheme at the construction design stage, that is, before construction begins. In this case, it is possible to fully familiarize yourself with the necessary regulatory documentation that relates to this issue. This approach will allow you to pre-take into account all sorts of nuances and avoid mistakes. In the Russian Federation, the most stringent requirements are imposed specifically on gas boilers in private houses (and not only). You can study the rules in the instructions for placing heat generators MDS 41-2.2000. Further in the article, all recommendations will come from this regulatory document.
It is allowed to install a gas boiler both in the kitchen and in a room specially designed for this (furnace). If a a private house has several floors, the equipment should be located on the ground floor or in the basement. Another option may be a separate building that is not related to residential space.
Placement of equipment on flat roof allowed in case of compliance with the rules for the reliability and bearing capacity of the coating.
General restrictions:
- when installing a gas boiler in the kitchen, its power can be no more than 60 kW;
- in a separate annex (room, furnace) it is possible to place equipment for heating and hot water supply with a total capacity of not more than 350 kW. If this indicator is exceeded, it is necessary to erect a heat generating building that will comply with the rules and regulations for the arrangement of a boiler room;
- regardless of the type of boiler room - the height of the ceilings should be at the level of 2.5 meters and above.
As for water heaters, it does not take into account the area of \u200b\u200bthe room, but its volume. In accordance with MDS 41-2.2000, for equipment with a thermal power of less than 150 kW, the norm is 15 m 3. For each subsequent kilowatt, an additional volume of 0.2 m 3 is added.
Placement of equipment should be done taking into account ease of maintenance. If such a need exists, place the gas boiler and other appliances with a margin of at least 700 mm from all sides. From the front to the nearest partition, a space of at least one meter is required, which corresponds to generally accepted standards for the placement of boiler equipment.
When the total power of the heaters exceeds 150 kW, they are placed only in annexes adjacent to outer wall. Inside the house, the placement of a gas boiler and other equipment that exceeds this indicator is prohibited. In addition, the installation is carried out taking into account the need for maintenance and laying engineering networks.
In the extension, it is important to have windows that will perform the following functions:
- Source of natural light.
- Acting as an easily dropped structure in the event of an explosion.
Based on the accepted standards for the arrangement of the boiler room, the size of the window is calculated based on the volume of the room, respectively, 0.03 m 2 for each cubic meter. Dimensions apply to glass only.
Boiler room ventilation requirements
When arranging the boiler room, the most milestone is proper ventilation. General rule states that the hood must provide air flow at the rate of three exchanges in one hour. In other words, the air in the room is updated three times within an hour. This parameter is calculated simply: the area is multiplied by the height (the volume is determined), then the resulting figure is multiplied by 3. In a private house, ventilation is organized in the traditional way - through a shaft or pipe.
Supply ventilation must compensate for exhaust air and supply oxygen in order for the combustion process to take place. The heat generator takes the mixture, and then throws out the recycled air along with the combustion products through the chimney. As a result, the supply air consumption is the total consumption of the air mixture for exhaust and combustion (this is prescribed in the standards).
Security required amount inflow is also carried out using additional holes in entrance doors. So the hood provokes the flow of additional air, which is required by the boiler room. Such a lattice can be built into both the outer door and the inner one. In the second case, already heated air will begin to flow, and the efficiency of the gas boiler will be noticeably higher.
Before starting work on arranging a home boiler room, consider the following tips:
- Do not rely on information that has been obtained only from the Internet, books or other information media. For each rule, advice, recommendation, there must be a corresponding confirmation by a normative document. In other cases, these are empty words and conjectures.
- After familiarizing yourself with all sorts of requirements and rules, get advice from specialized services that will issue a permit for the organization and operation of the boiler room. In addition to approval, it is really possible to get information from them about specific nuances that you might have missed.
- You should not engage in the design and implementation of a boiler room on your own. Engage a design service that will save you from many likely problems in the future. If the project is simple with low power, consult with a specialized engineer.
- Please refer to the regulations in your country. Do not apply the rules and requirements of other CIS countries. For the Russian Federation, study the relevant rules dictated by the current legislation.

There is one delicate question for the experts. We design houses, private cottages of different nature, from small to large.
it is necessary to lay a place for a future boiler room or furnace. As a rule, we do this with a margin in place, due to which the rest of the area suffers.
To what size can the area of an individual boiler room in a private house be reduced?
Mar 20, 2013, 05:17
There are different formulas and norms for the calculation. In general, it depends on which boiler is used. It's one thing - the usual atmospheric and another thing - a turbocharged one. SP 41-108-2004 indicates 15 cubic meters, the volume of the room, it seems to be an ordinary boiler.
I found the requirements here:
The area of the room for the boiler must be at least 6.0 m2,
room height not less than 2.2 m,
the volume of the room is not less than 15 m3,
passages must be at least 0.8 m.

it also requires a separate entrance and a window sufficient for natural light and the exit of the blast wave.
There is no difference in the volume of the room for atmospheric and turbocharged boilers by regulatory documents on the territory of the Russian Federation. Requirements for both - as for gas-using equipment.
The minimum area of the room is not standardized, it is taken from the condition of the possibility of installation and maintenance. The minimum volume, yes, is 15 cubic meters. Manufacturers of equipment in atmospheric burners, however, still recommend plus 0.8 cubic meters. volume per kilowatt of power, but this is an optional requirement.

Yes, there are requirements in terms of volume, but they are also for windows, that's for sure. The blast wave must come out through something, if God forbid! Furnaces are usually made in the basement. Pay attention to the plinths of buildings, they always have small windows that serve for ventilation and security. If the room is not even used for heating, these windows will blow through the possible accumulation of underground methane and secure the building.

There are also requirements for the minimum area, it’s just that someone knows, someone doesn’t
Are you mocking an old gasman?! There are no space requirements! If there is (yeah, SOMEONE knows), please provide a link to the regulatory documents.
A separate exit to the outside is required only with a certain capacity of the equipment, and not necessarily always.
"Fireboxes are usually made in the basement" - this is about nothing at all! Firstly, there is no such concept "furnace" in the standards for gas-consuming equipment, there is - "heat generator". Secondly, the placement of gas-using equipment in the basement is a special case and the wishes of the "client" have the same right to exist as placement on the 1st floor!

There is also a minimum height of the furnace room, equal to 2.5 m. Therefore, the minimum area is easy to calculate
15 / 2.5 \u003d 6 sq. m., that is the minimum area is clearly RATED, but the maximum, then here already based on the placement of specific gas-using equipment, the minimum distance in terms of between the boiler or boilers, and also from their front to the furnace wall. For installation additional equipment it is also necessary to use additional space and, in the end, this very minimum area for a private house becomes equal to 10 or even 15 square meters. m.
But True, this moment is done at the discretion of the owners! It is quite obvious that you do not need to hang the device so that you have to squeeze between the wall and its body. Yes, by the way, there are requirements for the size of windows for ventilation and explosion safety.

If you build a boiler room 4 meters high with a volume of 15 cubic meters, the requirements will be met, and the area will be 3.75 square meters, that is, the area is not regulated. The volume and height of the ceilings are regulated.
What is written here about height is humor and nothing more. It turns out that the ceilings in the house are somewhere around 2.50 or 2.75, and the boiler room is suddenly being built above the roof one-story house. Scream. Yes, this will never happen. On the contrary, they strive to make the ceiling in the boiler room smaller, lower. Why they do this is not even worth discussing.
But 6 sq. m. This is the minimum area of \u200b\u200bthe boiler room for a private house and not only. When choosing the actual area, the number of boilers and the number of pumps and the minimum distances from them to the walls and to the electrical panel also influence. And in each case, the size of the area can be 1.5 or even 2 times the minimum. This is how the substantiation of the real area of the boiler room actually happens without a far-fetched grotesque.

What are you talking about??? Absolutely correct... " by and large, one way or another, the area must also meet the requirements for ease of maintenance of thermal equipment."But this is no longer a minimum, but 6 sq. M. + Additional space for "CONVENIENCE". And convenience, as I wrote, depends on many factors, this is the number of boilers. In a private house, it is not uncommon to install two boilers, or even three. Convenience also depends on the number of pumps and their piping, and on many other things.
So you get 6 + 6 \u003d 12 square meters. m.
And the door in the boiler room should only open outwards ... this is for fire safety ...
A boiler room in a private house is a room with heating equipment that ensures the operation of hot water and heating systems.
The boiler room is necessary in the absence of central heating.
However, the arrangement of the boiler room cannot be called simple, because certain requirements are imposed on the room, which must be observed.
The requirements depend on the type of boiler and also on its location.
Therefore, you first need to complete the design: the project must contain all the details of the device and the standards for the room.
The boiler can be placed in many places:
- in the attic;
- in a separate building;
- in an autonomous module - a mini boiler house located in a container;
- directly in the house;
- in an outbuilding.
When planning housing, the best option would be to locate the boiler in the attic or basement.
However, if the house is already built, then it is better to choose an extension or a separate building.
A common option is a mini boiler room, in which all equipment is placed in a container. The small size allows you to install it anywhere.
In the photo you can see such a mini boiler room.
There are also mobile boiler houses, which are turnkey mini buildings. The walls are made of sandwich panels finished with non-combustible materials.
The device of the boiler room depends on the type of boiler being installed, which can be gas, solid fuel and electric.
Accordingly, the choice of premises depends on the type of heating equipment.
However, it is not enough to choose the type of heating and choose a suitable room, you still need to draw up a project. The project must contain a layout of equipment and display all standards.
For clarity, a diagram of the boiler room is presented.
Also, the project must be coordinated with special government agencies, mainly for gas equipment.
It is imperative to comply with the general requirements for all types of boiler rooms:
- no more than two boilers are allowed in one boiler room;
- walls are made of non-combustible material, such as brick or concrete;
- the floor must be made concrete or covered with a steel sheet, and tiled;
- the use of any combustible materials is prohibited;
- only a fire door is installed;
- the door of the boiler room and the adjacent room should open outward;
- in an attached building, one door should go into the house, and the other door into the street;
- unhindered access to the boiler equipment must be provided;
- the hood should provide three air exchanges per hour;
- a window must be installed, which should be with a window.
Standards for various types of boiler houses
There are other requirements for the room, depending on the type of boiler being installed.
All this is spelled out in the SNiP and requires the closest attention and strict adherence to all standards. What are the requirements for each boiler house, we will consider below.
Requirements for a gas boiler
SNiP standards allow the installation of a boiler with a power of up to 30 kW not in a separate room, but, for example, in the kitchen.
The dimensions of the room must comply with the following standards: minimum height - 2.5 m, minimum area - 6 square meters. m, the minimum volume is 15 cubic meters.
The size of the room is affected by the power of the boiler, which is explained by the release of combustion products. A window must be installed, the size of which also depends on the power of the boiler.
The minimum area that a window must have is 0.5 sq.m. A door with a width of at least 0.8 m is installed.
An obligatory element is the hood. Therefore, holes must be made at the bottom of the wall or door to ensure air flow.
For powerful equipment over 30 kW, according to SNiP, a separate room is required, which can be located both in the house and in a separate building.
If installation is carried out inside, then the following conditions must be taken into account:
- there should be a separate exit from the boiler room to the street;
- good natural lighting;
- high-quality hood;
- the walls of neighboring rooms must be fire resistant.
Of course, for powerful equipment, preference should be given to a room separate from the house, for example, a mini boiler room.
The device of this option is safer, less noisy and saves living space at home.
For a separate mini boiler room, you can use an autonomous module or build a mini boiler room with your own hands.
The following SNiP requirements are imposed on a separate room:
- the foundation of the boiler room and the foundation of a private house should not be connected;
- a separate base is required for a gas boiler;
- walls and roof are made of non-combustible materials;
- the boiler must be placed on a podium 20 cm high;
- the chimney is mounted on a separate foundation.
An example of the placement of a gas boiler is shown in the photo.
Requirements for a solid fuel boiler
This system is not classified as explosive, so the norms of SNiP are low. You can install equipment in the basement. The dimensions of the room are similar to the norms for a gas boiler room.
The floor in front of the firebox should have a steel sheet, and the remaining floor area should be concrete or lined with a fire-resistant floor covering.
A window must be installed, the size of which is determined as follows: 0.8 sq. m per 1 kW of boiler power.
The diameter of the chimney must correspond to the diameter of the nozzle on the boiler.
The hood is required, the volume is calculated as follows: 8 sq. cm of the exhaust area per 1 kW of boiler power, and if the equipment is located in the basement, then at the rate of 24 sq. cm per 1 kW.
A prerequisite for a solid fuel system according to SNiP is the availability of fire extinguishing equipment: a fire extinguisher, etc. The fire safety system is shown in the photo.
It should be noted that the same requirements apply to the mini-boiler room of a private house.
Requirements for an electric boiler
The safest option is to install electric heating. Separate placement of the boiler room in this case is not required.
Ventilation is also not needed, since the electric boiler does not emit combustion products. Therefore, separate boiler rooms are not needed, the electric boiler can stand anywhere.
However, there are also disadvantages - dependence on electricity and the need for high network power.
Installation work
In general, the installation of equipment is the same for all types of heating systems.
Therefore, we will consider installation using the example of the most common and at the same time the most difficult to install with your own hands and operate a gas boiler.
The wiring diagram of the heating systems is presented below.
Gas boilers are of two types: wall and floor.
wall model
Installation is carried out at an air temperature in the room from +5 to +35 degrees and air humidity - no more than 80%.
Installation begins with the finishing of the walls, which must be covered with heat-resistant material, 2 mm thick.
Since ventilation in the boiler room of a private house is important, ventilation holes must be made on initial stage installation.
To do this, a hole 15 cm in diameter is punched at the bottom of the wall at a height of 30 cm from the floor with access to the street, and a plastic pipe is inserted. A non-return valve is installed on the inside of the pipe.
In the same way, an exhaust hole is made. The ventilation scheme is shown in the figure.
Especially, ventilation is needed if the window and door are airtight.
Now you can directly mount the equipment itself. First, a bracket for the boiler is attached to the wall, which, as a rule, is included in the package.
The minimum height of the boiler is 80 cm from the floor. The bracket must be attached parallel to the floor.
When doing work with your own hands, you can check this with a building level.
After fixing the boiler, highest point system, you need to install an expansion tank and an air cock.
To prevent clogging of the heat exchanger, an angle strainer must be installed on the water supply pipe. It is advisable to install ball valves on the filter on both sides, as well as on the nozzles.
In the future, this will allow you to change filters without draining the water from the system. After that, you need to make a connection to the chimney.
Now you need to connect the pipes to the corresponding boiler nozzles, after removing the plugs from the manufacturer. The water supply pipe is connected from above, and the return pipe is connected from below.
It is better to connect by gas welding. When installing with your own hands, the slope of the heating pipes is not more than 5 mm per 1 m of the pipe. The pipe connection diagram is shown in the photo.
The next step is binding. The boiler must be connected to three systems: gas, hydraulic, electric.
It is better to connect the equipment to the gas pipeline not with your own hands, but with the help of a certified specialist.
Electrical piping and hydro piping can be done by hand. The hydraulic piping diagram will allow you to visually see the connection.
Binding is carried out subject to the following conditions:
- Hot gases and water in the heat exchanger must move in countercurrent, otherwise an explosion may occur. After completion of the hydropiping, all connections must be carefully inspected and it is advisable to repeat the inspection some time later;
- If there was antifreeze in the heating system, then it must be drained and the equipment washed several times to avoid an explosion.
Before installing the boiler, the following must be installed:
- valve / gas cock;
- counter;
- gas alarm;

The electrical system must be equipped with automation that will prevent short circuits and overheating.
Before the first start, the equipment must be filled with water to check the tightness.

Floor boilers are much more powerful than mounted boilers, so they are most often placed in a separate room.
For floor-standing equipment, the floor must be level and firm so that all feet are loaded evenly. It is better if it is a cement screed.
After installing the boiler with a boiler, the equipment must be brought to the chimney, and then to the heating system of the house with the installation of a filter that protects against blockage.
When connected to the water supply, the tie-in to the water supply should be placed as close as possible to the pipe inlet to the house.
This will ensure uninterrupted water supply and high water pressure in the system. Then the equipment is tied.
Thus, you can do the installation of heating equipment in a private house with your own hands, and compliance with all the rules and regulations for the arrangement of the boiler room, as well as for the installation of equipment, will ensure long-term and safe operation of the system.
