What are the requirements for installing a gas boiler? General requirements for the premises for installing a gas boiler in a private house. Boiler room volume

For heating a private house the best option, of course, is a gas boiler. This heating unit has high efficiency and allows you to quite smoothly and flexibly regulate the intensity of heating of residential premises, sometimes even without the use of additional thermostatic devices. Today gas is considered the most profitable fuel from an economic point of view, therefore the costs of such a boiler will quickly pay for its purchase and installation costs.

If you plan to install a gas boiler in a private house, the requirements for the room and the heating device itself must be clarified in advance. Having received general information, you can be convinced that you have to collect a lot of different documents and go through several authorities. Therefore, it is worth preparing not only theoretically and technically, but even psychologically for these rather unpleasant, but, alas, necessary events.

Sequence of preparatory activities

Basic regulatory documentation for boiler installation

All this data can be found in SNiP (Building Norms and Rules) 02/31/2001, “Gas supply country house. Requirements and rules for installing gas equipment.”

In addition to this document, you need to review additional ones containing information on the arrangement of boiler rooms and the rules for installing the boiler. They can also be found among " Building codes and rules":

SNiP 41-01-2003 “Heating, ventilation and air conditioning”.
SNiP 21-01-97 “Fire safety of buildings and structures.”
SNiP 2.04.01-85 “Internal water supply and sewerage of buildings.”

To install a boiler room in a private house, you should study SNiP 2.04.08-87.

How is a boiler room equipped in a private house?

In your own home, a separate room is usually allocated for heating equipment. What requirements must the boiler room meet? – detailed information about this is presented in a separate publication on our portal.

Coordination of gas boiler installation

In order to install a gas boiler in a private house or apartment, it will not be enough to study the SNiP documents. First you need to get technical specifications, which will become the basis for the organization further work for connecting equipment to gas mains.

To do this, the home owner submits an application to the local gas supply service, which indicates the estimated gas consumption required for use in a particular building for heating and other needs. This parameter is calculated approximately on the basis of SNiP 31-02 standards, clause 9.1.3, which provides the average daily gas volume for a single-family house:

— gas stove (cooking) – 0.5 m³/day;

— hot water supply, that is, the use of a flow-through gas water heater () — 0.5 m³/day;

- heating using a household gas unit with a connected water circuit (for central Russia) - from 7 to 12 m³/day.

At the local organization that controls gas supply and installation of boiler equipment, the request is reviewed by specialists. A document with technical conditions or with a reasoned refusal is drawn up for the applicant. The review process can take from one week to a month, depending on the efficiency of the control service.

If the request is satisfied, then technical conditions are issued, which must be fully implemented when installing gas equipment. This document will simultaneously serve as a permit to carry out the relevant work.

You need to know for sure that installing gas equipment without obtaining technical specifications is illegal. In addition, unapproved independent installation of a boiler is very unsafe, especially in cases where such work will be carried out in a multi-story building. Unfortunately, there are plenty of sad examples of this.

Installation project development

Once the technical specifications are received, you can proceed to drawing up the installation project.

The project is developed taking into account all the requirements specified in the technical specifications. This also includes a diagram for laying gas communications: for a private house - along the site to the entrance to the residential building, indicating this point in the drawing, and for an apartment - from the entrance to the gas supply pipe to the connection point to the heating boiler

The development of the project should be carried out only by design specialists who have a license to carry out work of this type. As a rule, an organization engaged in gas supply in a particular region (settlement) has a design department, where all such surveys, calculations and their graphic design are carried out.

Project approval

Further, finished project is sent for approval to the branch of the organization that controls the gas supply of the house where it will be installed. The period for approval of the submitted documents depends on the complexity of the project design, and can take from one week to three months.

The following documents with the characteristics of the boiler equipment must be attached to the boiler installation and gas mains project submitted for approval:

Technical data sheet of the gas boiler.
Instructions for its use.
Certificates of compliance with technical and sanitary requirements.
Examination data on the compliance of this unit with all applicable safety requirements.

These documents are issued to the buyer by the seller along with the boiler, and they are issued by the boiler equipment manufacturer.

If the project has not received approval, then in addition to a reasoned refusal, the applicant is given a list of actions that must be performed to obtain a positive conclusion.

If the project is approved, it is certified accordingly, which means that it is already possible to produce practical work for installation of gas heating equipment.

Basic requirements for the boiler room

A separate room must be provided for the installation of gas equipment with a power of 30 kW or more. It must comply with all existing standards and regulations. Quite often, for a boiler room, they try to choose one of the rooms in the basement or ground floor, but you need to know that such installation of a gas boiler is allowed only for single-apartment private residential buildings.

In a private house, a boiler of any power can be installed, since it is usually placed in a room attached to the house, thus having the opportunity to heat not only living spaces, but also utility rooms.

General requirements

The basic requirements for the boiler room are as follows:

The area of the room for installing one boiler must be at least 4 m². In this case, the total number of boilers in one room can never be more than two.
The ceiling height of the room is not less than 2200÷2500 mm.
The window, which is mandatory in a boiler room for natural light, must be sized at the rate of 0.3 m² of window area for every 10 m³ of room volume, but in any case not less than 0.5 m².
The width of the door opening must be at least 800 mm.
The distance between the front door and the boiler cannot be less than 1000 mm, but it is better if this interval is 1300÷1500 mm.
In order to be able to carry out maintenance and repair work, the necessary free space must be provided in front of the boiler, which must be at least 1300 mm.
The boiler must be installed stably and in a strictly horizontal position - this will minimize possible vibrations and noise.
The floor in the boiler room must be made of non-combustible material and be perfectly level.
The walls must also be made of non-combustible materials, and the surfaces near the walls of the boiler can be additionally insulated with heat-resistant materials.
The boiler room must be supplied cold water. The floor of the room must be equipped with a system for draining the coolant into the sewer system.
Electrical sockets must have a grounding circuit, since some elements of the boiler, for example, the ignition or the pump, are connected to the electrical supply.
It is necessary to provide access to the chimney - in particular to the inspection window - to control the patency of the channel and the possibility of cleaning.

Ventilation and chimney systems

Ventilation and exhaust systems for gas combustion products in the boiler room must be installed in compliance with the rules for installing gas equipment, since malfunction or ineffective operation of these systems can lead to either inoperability of the equipment, or, even worse, to an emergency and even explosive situation.

Prices for chimneys and pipes

chimneys

To ventilation and chimney regulatory documents the following requirements apply:

Ventilation and chimney ducts must be separated.

In order for fresh air to enter the boiler room, it is necessary to provide supply ventilation. The entrance window is made at the bottom outer wall or front door. The size of the ventilation window must be no less than 1/30 of the total area of the room, but not less than 80 mm² per 1 kW of installed power - for air flow from the street, and not less than 300 mm² per 1 kW, if the air flow comes from another premises.
The ventilation ducts must always be open, as air must circulate constantly.
It is recommended to install the boiler as close to the chimney as possible.
A chimney installed in a wall must have two inlet channels:

— the main one, for installation of the chimney pipe;

- inspection channel, located no less than 250 mm below the first one - this channel is intended for technological cleaning.

The exhaust vent of the chimney should not have a cross-section smaller than the outlet pipe of the boiler itself.
The chimney should not have more than three bends or turns.
The chimney pipe is made of stainless or carbon sheet steel. The use of asbestos concrete pipes or others made of layered materials is permissible only at a distance of at least 500 mm from the boiler chimney pipe.

In order for the operation of the boiler to be safe and the heating system itself to be effective, favorable conditions must be created to maintain normal draft. Therefore, it is very important to calculate both the total height of the chimney pipe and its location above the roof surface so that the head does not fall into the zone of the so-called wind backlash.

Installation of gas boilers - work high level difficulties. If only because installing any of these devices entails a mountain of paperwork.

Gas is the most popular fuel for heating boilers. Especially if we are talking about installing a gas boiler in an apartment or in a private house located within the city and with free access to gas communications. The publication's experts tell us what the difference is when installing a boiler in a private house and apartment.

Installing a gas boiler in a house: documentation

Do you want to install an autonomous heating system at home? Familiarize yourself with the requirements for installing gas boilers in homes.

IMPORTANT! Independent installation of a gas boiler in a house is illegal and unsafe, especially when it comes to changing communications in an apartment building.

The basic rules and regulations are prescribed in SNiP 42-01-2002 “Gas distribution systems”. SNiP “Gas Supply” 2.04.08-87 also contains many effective requirements. The latest document is not quoted today, but continues to contain a lot of useful information.

There are also additional standards for installing a gas boiler in a house, given in related SNiPs: on installations, on heating, on ventilation and air conditioning, on internal water supply and sewage systems of buildings, on noise protection, on safety precautions in construction, on fire safety buildings and structures, etc.

The installation of gas boilers in the basement or on the ground floor in a private house is permitted by the state only in single-apartment blocked residential buildings.

Specifications

Installing gas boilers in a house requires technical conditions for connecting to the city gas supply. To receive the document, write an application, making sure to indicate the estimated volume of gas consumption per hour. The document is drawn up at the city gas service.

Registration will take 1-2 weeks. If the application is accepted, consider that you have received official permission to carry out work.

Installation project

If the technical conditions are available, you can begin to develop a project for installing a gas boiler in the house. The “Gas supply” project is a diagram for installing a gas boiler in a house, as well as a diagram for laying a gas pipeline from the connection point to the city gas communications, and, in the case of a connection in the private sector, also a diagram for laying gas communications along the site indicating the entry point to the residential building.

The section is developed by design engineers taking into account the provisions specified in the GOS. They must have a license to design gas communications.

Coordination in Gorgaz

After finalization, the project is sent to Gorgaz for approval. Depending on the complexity of the project, its approval may take from 1 week to 3 months.

In addition to the Gas Supply project, the inspection is required to provide:

technical passport of the selected boiler;
instructions for its use;
certificates (sanitary and hygienic, compliance with technical requirements);
conclusions of the examination on the compliance of the gas boiler with all necessary requirements.

You are not the one who draws up the list of documents for installing a gas boiler in your home: they must be provided by the manufacturer.

If the project has not passed the review, in addition to an official document indicating the reasons for the refusal, you should receive a list of edits to correct the project.

If the project for installing a gas boiler in a house is drawn up accordingly, it is certified with a seal. You can begin installation work.

Installing a gas boiler in a private house or apartment: prohibitions

Installation of a gas boiler is not possible:

on combustible surfaces;
in the corridors;
in the bathroom;
in dormitories;
in rooms without windows;
in the basement;
on the balcony;
for LPG gas supply - on the ground floor.

Requirements for installing gas boilers in houses

The installation conditions for gas boilers can be reduced to the following standards:

the area of the room for installing a gas boiler must be at least 4 m²;
the entrance door to the room must be at least 0.8 in width;
the room should be well lit (0.3 m² of window per 10 m³ of room);
the ceiling height must be at least 2.5 m;
a grounding loop must be installed;
A cold water pipeline must be installed;
the cross-section of the chimney must correspond to the power of the installed gas boiler;
The walls of the room must be leveled and plastered.

Based on this, it is better to install double-circuit gas boilers in the kitchen, in the same place where the gas stove is installed. Kitchens in most cases are designed as boiler rooms, so installing a wall-hung gas boiler in the kitchen will not only comply with established standards, but will also significantly reduce the cost of connecting cold and hot water pipes.

Installation of a gas boiler is also possible on the floor. A floor-standing boiler, the installation of which, unlike a double-circuit wall-mounted one, requires a separate room reserved exclusively for the boiler room.

If we are talking about installing a gas boiler in wooden house, then the installation conditions remain the same. However, with a unit power of no more than 60 kW, the volume of the room should be from 27 m³. You can install the boiler in the kitchen on a wooden wall (or any other room, if all the necessary technical conditions are maintained).

With a power of up to 150 kW, the unit should only be installed in a separate room. The surface of the wooden wall on which you intend to mount the unit must be protected from high temperatures and flames.

Companies you can trust

BAXI (Baxi) is a Dutch company, part of BDR Therma, which occupies a leading position in terms of sales in six European countries, including Germany, Italy, Great Britain, Spain, France and the Netherlands. It produces a wide range of heating appliances, including floor-mounted and wall-mounted gas boilers.

Among the floor-standing units in the model range, it is worth highlighting BAXI SLIM - a series of gas boilers with a power range from 15 to 62 kW, with a built-in electronic flame modulation and self-diagnosis system. BAXI SLIM iN - single-circuit atmospheric without expansion tank and pump. Among the series of wall-mounted boilers, the BAXI FOURTECH series stands out, with a power from 14 to 24 kW with an antifreeze system when the boiler operates at temperatures below 5°C and digital control.

NAVIEN (Navien) - gas boilers from the South Korean manufacturer are attractive for their miniature dimensions (only 695x440x265 mm), as well as reliability of assembly. Navien boilers can operate at a very low gas pressure of 4 mbar. Please note that the normal value should be at least 13 mbar.

VAILLANT (Vailant) is a German company with official representatives in all European countries of the world, producing both double-circuit boilers (they have the function of heating the room, but also heating water), and single-circuit boilers (they also heat the room and heat water, however, using there is an additional boiler for this purpose).

ARISTON (Ariston) is an Italian company that has released the latest series of gas boilers with a built-in intelligent control system. Boilers from this manufacturer are known for their low noise level during operation, small dimensions, and comparative efficiency in gas consumption.

Danko is a Ukrainian-made equipment. Can serve as a good alternative when choosing between budget option domestically assembled and a more expensive unit imported from abroad.

ATON (Aton) is another domestic manufacturer that has put on the production line the production of seven types of boilers at once. The advantage of this brand is the use of Italian and German components.

Boiler: installation of a wall-mounted gas boiler

It is prohibited to do such work with your own hands, be it installing a wall-mounted or floor-mounted gas boiler.

Progress of preparatory work:

Installation must be carried out by specialists who have been issued a license to install gas equipment.
The room temperature during installation should be from 5 to 35°C, air humidity - no more than 80%.

Progress of main work:

Step 1 - Prepare a hole for the output of a coaxial pipe d=100 mm Step 2 - Installation of a gas boiler (wall-mounted) is carried out on a special bracket (must come as standard), fixed to the wall at a level Step 3 - Fixed device on the wall Step 4 - Decoding channels. To connect the boiler and the gas network of the house, a gas tap, a meter, a thermal shut-off valve, and a gas alarm are installed in front of the boiler. Step 5 - Connect ventilation pipe. Checking the fixation Step 6 - Connecting the gas boiler to the water communications. When installing a double-circuit boiler, in order not to clog the heat exchanger, install a mesh corner filter in the “return”. We recommend installing on both sides of the filter, as well as on all boiler pipes. Ball Valves

Connection to the electrical network is carried out with a three-wire wire. The connection must be grounded.

In Diagram 4:

cone;
chimney "sandwich";
double-walled bend 45°;
double wall tee 90°;
condensate collector;
neutralizer;
mounting bracket;
connection (transition);
pass-through glass.

IMPORTANT! A detailed installation diagram for a wall-mounted boiler should be included with each individual model.

Installation of a chimney for a gas boiler

The coaxial pipe is connected to the boiler and led through a hole in the wall to the street, outside the room. No further work is required.

Before the first start-up, the heating system is filled with water, disconnecting the boiler from the central power supply. The process of filling the system with water should take place gradually, allowing air to leave the system through special air vents.

Before starting, it is checked for gas leaks, sealing of the water supply system, and only after that it is connected to the electrical network.

Installation of a hood for a gas boiler

If the removal of combustion products cannot be ensured due to natural draft, install “ forced hoods": a pipe is installed in the roof or interfloor passage, a hatch is equipped for cleaning out soot, taking into account that the entire structure should not be complex - no more than three bends are allowed.

Installation of a floor-standing gas boiler in the house

This option is easy to transport and install: most floor-standing gas boilers are equipped with legs or wheels to facilitate their delivery to the installation site. They are also sold already assembled, so the only thing that remains for the buyer is to follow the instructions (the installation instructions for a gas boiler of any type must contain all the necessary drawings for connecting to the communications of the house and explanations for them).

There is a worthy alternative to floor-standing and wall-mounted gas boilers - a gas parapet unit. Unlike its counterparts, this boiler does not require a chimney or high installation costs.

This energy-independent heat generator is designed for autonomous heating and hot water supply of small apartments. The maximum power of such devices is 16 kW (instructions for installing a gas boiler of this type).

Gas boiler: installation of a parapet model

For most homes, installation codes prohibit the installation of gas equipment in basements or basements. However, exceptions include buildings that have received official permission from the designers and relevant regulatory authorities. Owners of houses or apartments can also obtain permission to install boilers in basements or basements.

The installation of gas boilers in private houses must be provided for in the architectural plan.

Rules for installing a gas boiler in a house: exceptions

Gas boiler installation height

The installation height of a gas boiler is determined by the height from the finished floor to the bottom edge of the boiler body. On average, this is 0.8 - 1.1 m.

Location of the gas boiler on the wall

Installation of gas boiler rooms

The main distinguishing feature in the technology of arranging gas boiler rooms is that the floor in such rooms must be equipped with a water drainage system.

In addition to gas boilers installed in interior spaces, there are also boilers outdoor installation. Such units are capable of heating not only a single apartment or a private house, but also an entire administrative building, school, hospital, high-rise building, etc.

Cost of installing a gas boiler in a house Widget from SocialMart

Considering that with your own hands installation work cannot be done, the cost of installing a gas boiler in the house will still hit your pocket. We warn you that the idea of installing autonomous heating, despite all the advantages of the system, is not a cheap pleasure.

Boiler cost: B Depending on the type of boiler and the power of the device, you will have to pay about $400-600 for it.

The cost of installing a gas boiler in a house: varies between $130-250 + the cost of transportation, purchase of components for installation (if not all components of the system were included with the device) - this is also about $35-60.

The ideal option is when the sale of the device and installation are the work of the same company. This way you will have guarantees not only for the quality of the device, but also for the quality of its installation. In addition, organizations that provide a full range of services (including warranty service) often work exclusively on a fixed payment: when ordering services, an estimate for the installation of gas boilers and components must be drawn up.

Installing a gas boiler: video of the step-by-step installation process

It is well known that natural gas is the most economical source of energy for heating a home. Therefore, the desire of owners of country houses to connect to gas seems completely natural. However, we must not forget that gas is the riskiest type of fuel in terms of explosion and fire safety. That is why the installation of a gas boiler in a house is carried out taking into account numerous rules and regulations that are imposed by supervisory authorities.

First of all, we note that the standards for the installation of gas boilers in a residential building are determined by several documents. The main ones are two sections of Construction Norms and Rules (SNIP) - II-35-76 and 42-02-2002. They contain requirements for the room in which the gas boiler is supposed to be used, as well as for the place where the gas line is inserted into it. Necessity gas heating may occur to owners different types real estate:

According to current legislation self installation gas equipment is prohibited. Installation, configuration and connection of heating boilers can only be carried out by authorized organizations that have the necessary certificates and licenses.

In what rooms is installation allowed?

You cannot choose the installation location of the gas boiler in the house yourself. It is approved during the approval of the heating system project along with the type of boiler, communications layout and location of the gas pipe entry point into the room. Permission to connect a boiler may not be obtained for all types of premises. Let's look at the main options in more detail.

Bathroom

The most controversial place for a gas boiler is the bathroom. Many owners of apartments and houses want to place a heating unit there due to lack of space in other rooms. However, gas workers almost always refuse such requests. Let's try to figure out why:

SNIP 2-04-87 contains an explicit ban on installing a boiler in the bathroom. However, this section was declared obsolete in 2002 and replaced by SNIP 42-01-2002, which no longer contains such a norm. However, gas companies take advantage of this uncertainty and refer to earlier requirements;
One of the requirements for the boiler room is the presence of a window facing the street. Most bathrooms don't have it, so they don't meet this particular parameter. However, theoretically, this drawback can be circumvented;
The same applies to the width of the door - it must be at least 80 cm;
Another limitation that may interfere with the approval of installation in the bathroom is the presence of high humidity and dampness. Indeed, the electronics that a modern gas boiler is literally crammed with can theoretically fail. But, on the other hand, the body of any boiler is absolutely sealed, and control boards are often specially treated with special protective films in order to protect them from moisture. So this is also not a 100% reason to refuse installation, especially since there are no explicit restrictions on humidity in any of the regulatory documents.

However, practice shows that almost no one can obtain permission to install boilers in the bathroom. The only one possible variant– if you are changing the old one geyser and carry out this like reconstructing the heating in a house.

Living spaces

Everything is much simpler here. SNIP 2.04.08-87 clearly allows the installation of boilers and water heaters only in kitchens and non-residential premises that meet certain requirements. We will present these requirements a little later, but for now we will simply note that it will not be possible to install a gas boiler, for example, in a bedroom or living room - gas specialists will never approve such a project.

Other premises

In the vast majority of cases, installing a heating system in a house or apartment requires the installation of a gas boiler with a capacity of up to 60 kW. Such a boiler can be placed in the kitchen or in any other place - there is only one requirement for the room - it must be non-residential and impenetrable.

For boilers of higher power, more serious restrictions are put forward:

Up to 150 kW – a separate room on the floor, including the basement;
Up to 300 kW - a separate room on the ground, ground or basement floor, as well as in an extension to the house.

The following table shows the design requirements for installing boilers of various capacities.

If you install a gas boiler in a room whose walls and floor are made of flammable materials, they must be protected using a separate fireproof structure with a thickness of at least 3 mm.

In a private house, a metal sheet laid over a layer of asbestos is perfect.

Stages prior to boiler installation

In accordance with the Housing Code of the Russian Federation, any change in the heating system refers to the redevelopment of the premises, which must be agreed with representatives of local authorities.

The project will necessarily reflect all the requirements for installing boilers, which we presented in this article. Therefore, if your system is installed in full accordance with the project, handing it over to gas workers will not be difficult. Let us remind you once again that the installation of gas equipment should only be carried out by authorized specialists.

Gas still remains the cheapest type of fuel. Accordingly, the cheapest heating is obtained using natural gas. True, installing a gas boiler is associated with certain difficulties - the premises must comply with fire safety standards.

To install powerful gas boilers, a separate room is required

Gas boiler installation standards

To avoid any troubles when putting the gas boiler into operation, it is necessary to select the installation location in accordance with current standards. The installation of a gas boiler in a private house (single-family or semi-detached) is regulated by SNiP 31-02-2001, and the installation rules in apartment buildings are prescribed in SNiP 2.08.01.

For private houses

According to the standards, a gas boiler can be installed in a ventilated room, which is located:

on the first floor of the house;
in the basement or basement;
in the attic:
gas boilers with a power of up to 35 kW (according to MDS 41.2-2000 up to 60 kW) can be installed in the kitchen.

There are currently two standards in force regarding the installation of boilers in the kitchen. According to one document, heating devices with a power of no more than 35 kW can be placed, according to another - no more than 60 kW. And we are talking only about heating devices. Gas stoves or other appliances using gas are not taken into account.

What to do? You need to find out what standards your GorGaz adheres to. After all, it is their representatives who will accept the equipment into operation. Actually, the designer should tell you all the details, but it is also advisable to know this - you will need to prepare the room for installation.

Where to put

Now about where and how to place gas equipment different power. We will talk about gas boilers and their power is summed up:

with a power of up to 150 kW inclusive - in a separate room on any floor, including the basement and basement;
from 151 kW to 350 kW inclusive - in a separate room of the first, basement or ground floor, as well as in a separate attached room.

More powerful installations are not used in private homes.

Requirements for kitchens in which a gas boiler is installed

When placing a flow-through gas water heater or a gas heating boiler with a power of up to 60 kW in the kitchen, the room must meet the following standards:

There is one more thing that is not specified in the standards, but which exists: installing a gas boiler is allowed only in a room with doors. In light of the latest trends - removing partitions and making doors instead - this can be a problem. Without a door, the permit will not be signed. The solution is to put or . Another option is glass doors. They do not “load” the interior, but they are perceived exactly as doors.

All these requirements must be met. If there are violations, they simply won’t sign the acceptance certificate for you.

Requirements for individual premises

They are similar, but there are some differences:

Ceiling height - at least 2.5 m;
The volume and area of the room are determined by ease of maintenance, but should not be less than 15 m3.
Walls leading to adjacent rooms must have a fire resistance limit of 0.75 hours and zero limit for the spread of fire through the structure (brick, concrete, building blocks).
An exhaust hood with the same requirements: for outflow - three times exchange, for inflow in the same volume, plus air for combustion.
The room must have a window. The glass area is at least 0.03 m2 per cubic meter of volume.

If equipment is installed with a power of 150 kW or more, one of the prerequisites is the presence of access to the street. A second exit can be equipped - to a utility room (not residential). This could be a storage room or a hallway. Doors must be fireproof.

Please note that when calculating windows, the glass area is considered, not the size of the window opening. Moreover, in some cases they require at least one glass with an area of at least 0.8 square meters. If enlarging the windows is problematic, you can make a similar window in the door (the regulations do not say that it must be in the wall).

How to attach boiler rooms

Sometimes it is not possible to allocate a separate room in the house. In this case, the boiler room is added. The standards for ceiling height, volume, glazing and ventilation remain the same as for individual rooms, only specific standards are added:

Please note that the extension must be registered. No one will give you gas without official documents. And one more thing: when designing it, lay down all the standards without deviations, otherwise they won’t accept it. If the installation of a gas boiler is planned in an existing room, they may turn a blind eye to some deviations or offer some compensation (if there is a missing volume or height of the ceilings, they may be asked to increase the glazing area). For newly constructed buildings (and extensions too) there are no such discounts: they must include all standards.

Combined kitchens

Today it has become fashionable to have or. It turns out to be a single large space in which it is easy to implement design ideas. But the gas service regards such premises as residential and prohibits the installation of gas equipment.

It will not be possible to solve the problem with a studio apartment, but with a combined apartment there is a solution. If you are just planning to combine the kitchen and living room, when preparing the documents, call the resulting room kitchen-dining room. This premises is not residential, so there will be no restrictions. If the papers have already been completed, you can try to redo them or go the other way - install a sliding partition. True, in this case, the documents will need to be redone.

Place for installing a gas boiler

If we talk specifically about apartments, then gas boilers are installed in them, mostly in the kitchens. There are all the necessary communications: running water, gas, a window and an exhaust hood. All that remains is to determine a suitable location for the boiler. For this installation, wall-mounted (mounted) boilers are used. They are installed on several hooks fixed to the walls (usually included in the kit).

As for installation in other areas of the apartment or house, as a rule, none of them meet the requirements. For example, in the bathroom there is no window with natural light, the corridor is usually not suitable in size - there is not enough tolerance from the corners or to the opposite wall, there is usually no ventilation at all or it is insufficient. The problem with storage rooms is the same - there is no ventilation and windows, there is not enough volume.

If there is a staircase in the house to the second floor, the owners often want to place the boiler under the stairs or in this room. In terms of volume, it usually passes, but in terms of ventilation it will have to be very powerful - the volume is considered to be at two levels and it is necessary to ensure its threefold exchange. This will require several pipes (three or more) of a very large cross-section (at least 200 mm).

Once you have decided on the location for installing the gas boiler, all that remains is to find a place for it. It is selected based on the type of boiler (wall-mounted or floor-standing) and the manufacturer’s requirements. The technical data sheet usually specifies in detail the distances from the wall on the right/left, the installation height relative to the floor and ceiling, as well as the distance from the front surface to the opposite wall. These may vary from manufacturer to manufacturer, so it is worth reading the manual carefully.

Installation standards according to SNiP

Gas boilers can be installed on fireproof walls at a distance of at least 2 cm from it.
If the wall is fire-resistant or combustible (wooden, frame, etc.), it must be protected with fireproof material. This can be a three-millimeter sheet of asbestos, on top of which a sheet of metal is fixed. Plastering with a layer of at least 3 cm is also considered as protection. In this case, the boiler must be hung at a distance of 3 cm. The dimensions of the fireproof material must exceed the dimensions of the boiler by 10 cm from the sides and bottom, and from the top must be 70 cm larger.

Questions may arise regarding asbestos sheet: today it is recognized as a material hazardous to health. You can replace it with a layer of cardboard from mineral wool. And also keep in mind that ceramic tiles are also considered a fireproof base, even if they are laid on wooden walls: a layer of glue and ceramics provide just the required fire resistance.

The installation of a gas boiler relative to the side walls is also regulated. If the wall is non-flammable, the distance cannot be less than 10 cm. For flammable and non-combustible walls, this distance is 25 cm (without additional protection).

If a floor-standing gas boiler is installed, the base must be non-flammable. A non-flammable stand is made on the wooden floor. It must provide a fire resistance rating of 0.75 hours (45 minutes). These are either bricks laid on spoons (1/4 brick size) or thick ceramic floor tiles laid on top of an asbestos sheet fixed to a metal sheet. The dimensions of the non-combustible base are 10 cm larger than the dimensions of the installed boiler.

The problem, which is associated with the lack of central heating and hot water supply, as well as the poor quality of these services, can today be solved by installing a gas boiler.

Boiler selection

To do this, you can choose single-circuit or double-circuit equipment. The first option can provide only one process, which can be, for example, heating. Whereas dual-circuit equipment guarantees two processes, namely heating and water heating. Installing a gas boiler in a private house is quite troublesome and time-consuming, this is largely due to the fact that the master will have to ensure compliance with all rules and regulations. It is also worth remembering that the operation of such equipment is always associated with some risks, which is why it is necessary to follow fire safety rules.

Basic rules for installing gas equipment

If you decide to install a gas boiler in a private house, you will need to prepare documents and carry out certain actions. A contract for the supply of gas to an individual consumer will be needed. The installation project, as well as all technical conditions, must be agreed upon with the city gas service representative. The heating system must be pressurized to 1.8 atm.

It will be important to de-air the heating system. The technician will have to analyze the connections for leaks. A voltage stabilizer is installed for the boiler; it is important to take care of the presence of an uninterruptible power supply. It is unacceptable to add antifreeze to heating water. This can cause damage to the gaskets, leading to leaks in the heating system.

Premises requirements

If you decide to install a gas boiler in a private home, it is important to check whether the room complies with the standards. We are talking about the room in which the boiler is supposed to be placed. in a single-family house may involve the installation of a furnace or boiler room at any level, this could be the roof, attic, basement or basement. The restrictions are the living quarters, as well as the bathroom and bathtub. To determine the volume of the room that will play the role of a boiler room, it is necessary to take into account the total thermal power of the equipment, capacitive or instantaneous water heaters. When installing a gas boiler in a private home, it is recommended to take into account that there are some exceptions. Thus, if the boiler has a closed combustion chamber, then the volume of the boiler room is not standardized, and a window with access to the outside may also not be installed.

Air flow

To remove and supply air, it is important to organize an influx of the required volume. In order to provide equipment power of 23.3 kW, about 2.5 cubic meters of gas must be burned per hour. In order for this volume to burn completely, you will need 30 cubic meters of air for an hour. If an insufficient amount of oxygen is supplied, the gas will not burn completely, and ultimately a harmful substance will begin to accumulate, while its inhalation will have a negative impact on human health.

If you do it yourself in a private house, then it is especially important to ensure that air flow is ensured not only from outside, but also from other rooms of the house. This can be achieved by creating a gap between the floor and the door. It is necessary to mount the boiler on the floor with a step of 10 cm from the wall, which is important to cover with non-flammable material.

Features of work on the installation of gas equipment

Installation of a gas boiler in a private house, the price of which should interest you at the first stage, requires compliance with rules and regulations. When planning the room in which you intend to place the boiler, you need to make it such that the area is 4 square meters or more. Ceilings must be 2.5 meters high or more. It is important to pay attention to the width of the door that goes into the room; it should be equal to 80 cm. Installation of a wall-mounted gas boiler in a private house is carried out in such a way that the equipment is illuminated naturally through the window opening.

It is important to note that for every 10 square meters there should be 0.3 square meters window. It is necessary to provide intensive ventilation, since gas combustion is carried out due to the flow of air. The area of the opening for the intake of outside air should be 8 square centimeters per 1 kW of equipment power.

When installing a floor-standing gas boiler in a private house, it is important to take into account the fact that the gas pipeline pipes must be made exclusively of metal. It is important to remember that flexible hoses can only be used to connect consumers.

What you need to know about the chimney cross-section

The cross-section of the chimney should not be neglected, which must correspond to the available power of the boiler. If the equipment power is 30 kW, then the chimney diameter should be equivalent to 130 millimeters. When installing gas boilers, the rules and installation features require the use of a chimney with a diameter of 170 millimeters with an equipment power of 40 kW. It is unacceptable for the cross-sectional area of the chimney to be smaller than the cross-sectional area of the hole for connecting the chimney. The upper end of the chimney should be 0.5 meters or more higher than the roof ridge. The electrical power supply system of the equipment must have a circuit breaker equipped with thermal and current protection.

Features of installation of boiler equipment

If you are carrying out installation, a gas boiler for heating a private house must work in conjunction with a gas analyzer, which will be able to warn of a possible gas leak. Among other things, you need to make sure there is an electric valve that shuts off the fuel supply. If you have to work in an apartment building, installing gas equipment in the basement is unacceptable. Each device must be supplemented with gas meters. As for ventilation, it should be in the upper part of the room.

Features of installing wall-mounted equipment

When installing gas boilers in a private house, the work flow diagram allows you to eliminate errors. Wall-mounted equipment is mounted in cases where power requirements are not too strict. Among other things, this arrangement of equipment can be chosen when there is not too much free space. Most often, such boilers are used in multi-storey buildings. Installation of wall-mounted equipment allows you to provide an autonomous additional heating system, which can be installed even in houses with central heating. Do-it-yourself installation of a gas boiler in a private house can be done above other appliances that are installed on the floor, this is due to the fact that boilers are not too demanding on free space. It is permissible to mount wall-mounted equipment in cascade. This is advisable if there is a need for significant power.

Installation indirect heating can be performed at a distance of 20 centimeters from other gas appliances, as well as materials that are flammable. Depending on the equipment model and power, the distance between the boiler and the wall can vary from 30 to 50 centimeters. It is not recommended to place the boiler near a window or in an opening between walls. The power source should be located as close as possible. Before the boiler is installed in its place, all pipes, equipment and systems must be flushed with water. This will get rid of foreign particles that may have entered the system during the assembly process.

Nuances of the work

The strips that are used to fix the boiler must be installed in increments of 0.8 meters; as for the maximum distance, it is 1.6 meters from the floor surface. It is necessary to analyze the wall for evenness and strength; it must support the weight of the boiler itself and associated devices. When produced in a private house, the wall is provided with a gasket made of non-combustible material, the thickness of which should be 3 millimeters. In this case, the boiler is fixed at a distance of 4.5 cm from the wall surface.

Before the equipment is connected to the pipes, it is necessary to remove the plug that is installed on the pipes. In order to prevent clogging of the heat exchanger, it is recommended to install a corner strainer at the water inlet. It is important to install ball valves on both sides; this should greatly simplify further maintenance and repairs. Afterwards, it is important to check how level the equipment is installed. Skewing to one side can lead to negative consequences. Connection gas pipes equipment should be accessed using steel pipe through special bends, it is important to ensure a rigid connection. Important to apply At this point we can assume that the installation of a gas boiler in a private house, the price of which starts at 5,000 rubles, has been completed.

Requirements for the chimney device

It is important to choose the right material for the chimney, which will depend on the type of equipment and fuel used. For a gas boiler, it is necessary to use pipes that are cylindrical in shape and made of metal; it is preferable to use stainless steel. Such products will be the safest, most reliable and durable. It is important to install a hatch to clean the chimney. In order to make it convenient to collect soot during the cleaning process, it is necessary to leave an empty space under the chimney entrance. When installing this part of the boiler equipment, you should not make more than three turns and bends.

The pipe that connects the chimney to the boiler should be as short as possible, its length no more than 25 cm. The vertical section at the outlet of the equipment should be equal to 2 diameters or more. Beyond this section, the pipe must be brought out to the connecting section, and after that it must be turned upward with a slight slope towards the equipment. Smoke removal in this case will be carried out due to natural draft.

Conclusion

The cost of installing a gas boiler in a private house will be less if you install all the equipment yourself. However, it is necessary to take into account the fact that the connection of the system is still carried out by a professional team of craftsmen. This is necessary to ensure that all fire safety rules and regulations are strictly observed. After all, this is the only way to protect yourself and your home from a fire that may occur due to improperly installed heating equipment.
