Using a gas floor-standing boiler to heat a house or apartment is considered the cheapest and quality option. At the moment, this issue is quite relevant, so there is a wide selection of modifications on the markets from both domestic and foreign manufacturers, differing not only in price, but also in the presence of various functions and additional options.

In order to independently understand the offers and choose a good, economical floor-standing gas boiler, you need to analyze a lot of information that will help you choose best option.

Principle of operation

Gas heating device

Almost all floor-standing gas boilers operate identically. To operate them, natural or liquefied gas is used as an energy source, which, when burned, heats the heat exchanger located inside it.

The latter contains water, which is heated and circulated through the system. In this case, for high-quality heating of the room, you need to choose a device with a high-quality heat exchanger.

Conventionally, they can be divided into several categories, differing in the material from which it is made:

Cast iron. Recognized as the most durable, as it is not subject to corrosion and has high stability to burnout. There are many cases where such an element has worked for 50 years. Among the disadvantages is that cast iron is considered fragile material. Sharp drop temperature of the liquid inside it or mechanical impact may cause damage to the housing.
Steel. Floor-standing boilers with a steel heat exchanger are significantly lighter and more resistant to possible impacts. But a significant drawback reduces them positive characteristics. This is primarily due to the fact that metal will burn out much faster than cast iron, and it is also susceptible to corrosion. Therefore, the average service life of such devices is significantly lower and is only 10 years.

To compare the efficiency that gas engines have floor standing boilers, a table is provided that analyzes the use of heating devices operating on different types fuel.

The information is presented using the example of heating for a private house with an area of 350 m2. The data are given in average values based on 6 months of the heating season.

Single-circuit

A single-circuit floor-standing boiler is considered the most common. The advantage of using it is the following characteristics:

efficiency. The cost of such boilers domestic production varies around 20,000 – 30,000 rubles. In addition, long-term operation is confirmed by reviews;
maintainability. While for some types of imported devices it can be difficult to find the part you are interested in, for a Russian heating boiler parts can be found in every city. And do minor repairs you can do it yourself;
lack of complex electronics. This makes it easy to maintain and use without training;
low gas consumption.

Gas boilers for heating a private home come with an open or closed combustion chamber. The difference is that the former use fresh room air to function, while carbon monoxide discharged through the chimney.

The second, using fans, takes air from the street and similarly removes exhaust gas outside. An open boiler operates according to the principle gas burner: They heat up and warm the air around them. From this we can say that their efficiency is significantly lower than that of a closed one, from which all the heat goes into the heat exchanger.

Dual-circuit

The cost of such a device will differ from single-circuit ones by 20 - 30% big side. But this is explained by a number of reasons that characterize it on the positive side:

high heat transfer;
performing a dual function: heating and supply hot water;
a wide range of options equipped with electronics, which allows us to talk about reliability and self-stop when a malfunction is detected.

Floor installation gas boiler do-it-yourself double-circuit type is not particularly difficult. To do this, you need to connect it to the heating pipeline and connect it to the water mixer. After this, contact a specialized workshop to call a technician who will connect the boiler to the gas pipeline and carry out the first start-up of the device.

Considering the principle of operation, we can distinguish 2 main actions:

when the hot tap is opened, the gas supply to the heat exchanger is turned off;
in this case, the burner operation switches to heating the circuit associated with heating the water supply. In this case, the heating procedure itself is carried out in flow mode without the use of storage tanks.

Separately, it should be noted that automatic shutdown, based on electronics, will only work if there is a power supply. If the power is turned off, the functionality of such equipment will drop sharply.

Special requirements

Modern gas floor-standing boilers meet all safety requirements and comply with regulations. In some cases, it is practiced to use combined devices in which, when the gas supply is turned off, the system automatically closes the valve and starts it from the electrical network. See all the pros and cons of installing a double-circuit boiler in this video:

Most simple models They are not equipped with automatic equipment, so you need to switch them yourself. Therefore, it is recommended to periodically check its performance in case of possible outages.

Entrust boiler installation to specialists

Gas is considered a source of increased danger, therefore, to connect a gas boiler in a private house, it is necessary to invite a specialist licensed to carry out this activity.

When building a private house, the issue of planning should be taken very seriously. The fact is that the installation of a gas floor-standing boiler is allowed only if all conditions are met. They are regulated by the requirements specified in SNiP and fire safety regulations. Any non-compliance or deviation from them will result in best case scenario during periodic inspection, the owner will receive an administrative fine, and in the worst case, it will end in an explosion or fire.

On electric boilers These requirements do not apply; they can be installed anywhere. But to achieve a violation of the aesthetics of the room, it is recommended to use a special room for these purposes.

Advantages and disadvantages of AOGV

AOGV is optimal in terms of fuel consumption and heat transfer

A floor-standing gas boiler for heating a private home is considered the most popular for newly built or renovated buildings.

When you contact a specialized organization with a question about what equipment to install to heat your home, most likely you will receive the answer that it is a floor-standing AOGV. This is primarily due to the fact that in terms of material consumption and heat transfer, gas is the leader in this rating.

Advantages

The main inspection of the installed gas boiler will take place in winter

The wide popularity of gas floor-standing boilers for heating residential and non-residential premises This is explained by the fact that such equipment has a number of advantages that distinguish it from its main competitors.

First of all, these are significant savings, the ability to perform partial installation yourself, ease of further maintenance and ease of operation. In addition, we can highlight a number of other advantages of such equipment:

Flaws

If you are afraid of fire, do not choose devices with an open burner

Despite the fact that a floor-standing gas boiler has such significant advantages, before giving it preference, you should familiarize yourself with special conditions its design and operation, which can be presented as shortcomings of such equipment.

For some they may seem insignificant, but for others, on the contrary, they may seem significant. Here are the main ones:

Before installing floor-standing gas heating boilers, you need to collect a lot of permitting documentation. For example, approval from the State Technical Supervision Service, providing a project for the upcoming installation, a chimney inspection report, a floor plan in which a specific place is allocated for its installation.
Low pressure in the gas pipeline can lead to the fact that they begin to smoke, as a result of which the chimney becomes clogged and the efficiency of the equipment decreases.
Choosing devices with an atmospheric burner is not advisable for people who are afraid of open fire. This is due to the fact that in such boilers the flame is in plain sight.

When faced with the question of how to choose the best option for your home, you should give preference to boilers equipped for operation in Russia.

This is due to the fact that the pressure in the system can change significantly, therefore, having dropped to a minimum level, the imported burner can begin to burn itself, which will lead to failure of the entire boiler.

Boiler selection

Which is the best floor-standing gas boiler to buy for your home? This question is asked by almost everyone who is faced with its acquisition. IN in this case you will have to face the following questions:

single-circuit or double-circuit;
imported or domestic;
with open burner or closed.

Having resolved all these issues, the problem of determining the power of the device will arise. It should be noted that this value directly depends on the area of your house, the presence of warm pilaf in it, which is used to heat some rooms, the number of residents and a number of other reasons.

Observe safety precautions when working with gas equipment

Having decided to install such equipment with your own hands, in order for it to provide high-quality and economical heating of the room, you should take into account that natural gas is an explosive and flammable substance.

Therefore, even if you know how to install floor-standing gas boilers for heating, you cannot do it yourself. As mentioned earlier, for this purpose there are specially trained licensed specialists who will perform this work correctly, and most importantly, in compliance with safety regulations.

Choosing to stay a private house, the owners solve several problems at once and free themselves from the need to put up with the difficulties that plague the inhabitants of city apartments. In order to achieve high level autonomy and provide the house with an independent source of heating, homeowners install a gas boiler in a private house in accordance with the requirements of the heating scheme. The device creates comfortable temperature conditions and allows residents to enjoy cozy atmosphere even in the coldest winters.

Correct installation of a floor-standing gas boiler or a wall-mounted equivalent provides users with the following benefits:

Direct installation of a wall-mounted gas boiler in a private house is a responsible and labor-intensive process. It requires knowledge in the field of heating engineering, and also involves the use special equipment and a whole list of auxiliary fittings. Since the device burns natural gas in the process of heating water into heat exchangers, during installation the following must be observed: certain rules, which will reduce the risks of accidents and provide the opportunity for a long time use a safe and reliable heating source.

Before starting the active phase of work, it is necessary to study the standards for installing a gas boiler in a private house, and also coordinate actions with representatives of the relevant utility offices.

The property owner must have the following papers in his hands:

The basic rules for installing a gas boiler in a private house are general. They require a number of preparatory actions on the part of the user. He will need to optimize the system and prepare it for installation.

To do this you need to do the following:

Choosing a location for installing the device in the house

Unlike apartment residents, who face some problems when installing a heater, owners of private houses have much greater freedom of action. For example, the installation of a gas boiler in a private house, the requirements of which prohibit the installation of the device in living rooms and bathrooms, can be done in the furnace (boiler room). If special room is not provided for by the design of a private house, then the owner can independently determine the place for drilling the brackets and attaching the wall-mounted boiler.

The current standards for installing a gas boiler in a private house, adopted at the state level, allow the installation of a heater in the following rooms, which can be converted into a furnace room:

Requirements for room space and its layout may change, so each project is developed individually.

If a wall-mounted gas heating boiler has a sealed, closed combustion chamber, then it can be placed in a room of any size.

If technical specifications installation of a gas boiler in a private house stipulates the location of the device in a room of a certain area and requires the presence of windows, then the owner will have to re-equip the house in accordance with the requirements of the project.

The distance from the wall to the boiler can be from 3 mm to 4.5 cm. The choice of the exact location depends on the boiler model and design features walls. Thus, the choice of location has many nuances, so the owner will not only have to find out how much it costs to install a gas boiler in the house, but also provide for all the features of its placement in the furnace room.

Installation of the device

As you can see, before installing a gas boiler in a private house, the property owner has to do a fairly large amount of work. During its implementation, an approved scheme for installing a gas boiler in a private house will be required, regulating all further actions from the installers.

Home distinctive feature wall heaters are their compact dimensions.

If a regular floor-standing boiler needs to be installed on a special pad and at the same time care must be taken to allocate a sufficient amount of free space around the device, then a wall-mounted analogue can be installed above other household devices.

The main thing is to comply with some requirements. One of them stipulates the features of hanging the device - it is important that there is at least 200 mm of free space from the outer walls of the boiler body to other devices and interior items. In this case, there should be no flammable objects, doorways or windows nearby. You should also prepare a power source in advance - the outlet should be located near the heater, otherwise the owner will have to use a carrier.

When the installation location of the boiler has been approved, the owner must check the equipment included. IN standard version it is represented by the following elements:

Before gas boilers are installed in a private home, the price of which is approximately from 5 to 15 thousand rubles, the owner will have to flush all the tubes and hoses that became clogged during assembly and transportation of the boiler.

When starting in a private house, the price of which depends on many factors, it is important to choose the right height for drilling the brackets. It is recommended to raise the boiler from the floor to a height of 80 to 160 cm. When the slats are installed on the wall, the boiler is hung on them. The device cannot be skewed, so you need to take a building level or a laser pointer and make sure that the boiler is hung level.

Next comes the connection of the pipelines to the corresponding boiler pipes. It is advisable to install a filter equipped with shut-off valves for the water supply. You should also connect the pipeline to the boiler. You should definitely use a paronite gasket for this.

Direct start-up of the boiler is carried out by representatives of special services, who will verify the correct installation of the device and give the go-ahead for its full use.

Installation cost

Homeowners who plan to implement an autonomous heating system are often interested in the cost of installing a gas boiler in a private home, carried out by employees of certified companies. Their services are used by clients who do not have the time or skills to self-connection boiler

It is worth noting that the cost of services depends on various factors:

On average, installing a double-circuit gas boiler in a private house will cost property owners about 5,000-6,000 rubles. Specialists can install a single-circuit boiler for a slightly smaller amount.

Additional funds may be charged for project preparation, individual production of brackets and grooves, pipe laying, manifold (manifold) piping, etc. The presence of non-standard walls, the thickness of which does not allow the use of conventional equipment for drilling holes and requires powerful equipment.

Choosing a good, powerful boiler for your home is a difficult task for the homeowner. But proper installation of the device also has great value, and is no less responsible. By following the rules for installing heaters in private homes, the owner implements a reliable and effective system heating system that will work properly throughout its entire service life.

There are currently many different solutions available on the market that you can use to provide heat to your home. One of the most common options is to install wall-mounted gas boilers. Despite the relatively recent appearance of wall-mounted models, they quickly became popular. Sometimes such equipment is simply called mini-boiler rooms, because a lot of important elements, providing reliable and effective work unit. However, in order for the heating equipment to work correctly, you need to know how to install a gas boiler.

Wall-mounted gas boilers can be located in the kitchen, bathroom, or any other room.

Features of installation and connection of a wall-mounted gas boiler

Inside, a gas wall-mounted boiler has a number of elements necessary for its operation, namely:

a heat exchanger equipped with a burner and a unit operation control device;
expansion tank;
circulation pump;
security system.

To correctly install a wall-mounted gas boiler, you need to know the rules and features of its installation, as well as have at least basic skills in working with such equipment.

A wall-mounted gas boiler can be single- or double-circuit. A single-circuit wall-mounted gas boiler can provide the house with heat, and a double-circuit one can also provide hot water. Gas boilers can be divided into atmospheric and turbocharged. In any case, depending on the technical characteristics of the equipment, they will have various features installations.

You need to understand that a wall-mounted gas boiler can have an open or closed combustion chamber. So, in the first case, combustion products and smoke are removed naturally. In a closed chamber, a fan is used for smoke removal. For equipment with an open chamber, combustion air is taken directly from the room. However for proper operation For such a unit, a number of recommendations must be followed.

Before connecting a wall-mounted gas boiler to a previously installed chimney, you must make sure that it is clean, because During operation, dirt may fall off and block the exit of combustion products. Connecting such equipment to an existing chimney must be done exclusively using metal pipe, resistant to mechanical wear and high temperatures, as well as exposure to aggressive environments such as condensate and combustion products.

Before turning, at the outlet of the unit, the length of the vertical section of the connecting section must be greater than 2 pipe diameters. After this section, the pipe should have an ascent with a slope directed towards the boiler.

Wall-mounted gas boiler with a closed combustion chamber

If we consider a wall-mounted gas boiler with a closed chamber, it should be mentioned that combustion products are removed in this case using a fan. Air to support combustion is taken from the street. Such a boiler does not need to be connected to an individual chimney. The outlet can be carried out into a collective chimney or using a coaxial chimney built into outer wall. The main thing is to ensure that no dirt gets into the fan mounting area during installation. Be sure to check this location before starting up the equipment.

You need to make sure that the intake pipe fresh air located at a height of at least 220 cm from the ground, and it protrudes from the wall by at least 18 mm. Pay attention to the position of the chimney system pipes. The pipes must be inclined downward. This is done so that the condensate formed during the combustion process can be removed from the chimney. The space between the wall and the pipe must be carefully sealed. This will prevent dirt and rainwater from entering the house through this hole.

It is necessary to take into account the fact that there must be no obstacles of any kind at a distance of at least 15 cm in front of the gas outlet pipe. Structures located above the chimney must be located at a height of at least 25 cm. Otherwise, the flow of exhaust smoke will be disrupted, which may lead to improper operation of the unit or even cause emergency situation. And finally, you need to make sure that the chimney pipe is not clogged or loose.

Before installing a wall-mounted gas boiler, you need to notify the gas supply service at your place of residence about your intentions for installation.

Everything is agreed upon there necessary actions and equipment installation diagram.

When purchasing a new gas boiler, be sure to check the delivery contents. After unpacking, the unit should be in perfect appearance, and an instruction manual must be included with it. If any part is missing, be sure to contact the suppliers and solve the problems.

Needs to be verified specifications indicated on the device box and on the boiler itself. In addition, you need to make sure that these indicators correspond to the figures given in the boiler operating instructions. Before installing the equipment, you need to clarify whether the device will work normally with the type of gas supplied.

The wall-mounted gas boiler should be prepared for installation. Before installing the unit, it is necessary to flush the pipes from various types of foreign particles. It is necessary to flush the heating system lines. A wall-mounted gas boiler can only be installed on a vertical, flat surface capable of supporting the weight of the unit itself and the connected additional equipment. Here you need to take into account both the material from which the wall is made and the load-bearing capabilities of the fastening elements.

If the boiler is installed on a wall made of flammable materials, a sheet of non-flammable material with a thickness of at least 3 mm should be installed under the device, and the boiler itself should be installed at a distance of at least 5 cm from the wall.

For a wall-mounted boiler, it is necessary to organize separate wiring with a switch and stabilizer. This system must be provided with grounding. The device must hang perfectly level on the wall.

Before execution installation work It is necessary to provide the necessary space on the wall for installation. The distance between the ceiling and the boiler must be at least 500 mm, between the boiler and the floor - from 800 mm. The first start-up and setup of the unit and all accompanying equipment must be carried out in the presence of a gas company employee.

Most modern private houses have gas boilers. This device can be called affordable, safe and economical, but it belongs to the group of expensive and difficult to install products.

Gas boilers are divided into two groups: single-circuit and double-circuit. The first type is used to heat the room, the second type can simultaneously heat the room and heat water. Therefore, it is important to know the rule of how to install a double-circuit gas boiler in a house. The equipment also differs in power and type of installation.

How to choose a boiler

An important rule for installing a gas boiler in a private home is determining the required power. Low productivity does not allow obtaining the required effect. Too much power is not economically beneficial and is dangerous, since acidic condensate formed as a result of constant temperature changes negatively affects some parts of the device.

To determine the boiler power, it is necessary to divide the area of the house by 10 and multiply by the appropriate coefficient, the value of which depends on the region of residence. For example, for central regions a value of 1.2-1.5 is used, for southern regions - from 0.7 to 0.9, in regions with a predominance of cold - 1.5-2. From this we can conclude that for a house of 120 m2, located in the south of the country, it is enough to purchase an apparatus with a capacity of 8-10 kW.

Using special devices you can change the boiler power value. At the same time, low-capacity devices have a single-stage regulator, middle-class heating appliances are characterized by two-stage regulation, and high-capacity boilers have a modulated regulator.

Gas boilers can be wall-mounted or floor-mounted. Depending on this, the installation of the device has its own subtleties. In addition, direct installation of gas equipment in a private home requires mandatory compliance with certain rules in accordance with Sanitary Standards and Rules.

In particular we're talking about about the following:

SNiP 41-01-2003 “Heating, ventilation and air conditioning”.
SNiP 31-01 from 2003 “Residential and multi-apartment buildings”.
SNiP 42-01-2002 “Gas distribution systems”.

Rules for installing gas appliances

For the premises are presented following rules gas boiler installation:

To install the boiler you need separate room, which can be located on one of the floors of the house, in the basement or attic. Installation of equipment in residential premises and bathrooms is not allowed.
The boiler room in which the gas boiler will be installed must have certain dimensions. For example, for boilers with a power of less than 30 kW, which are able to cover all the heating needs of a private house, a room with an area of more than 4 m2 is required. Boilers with a power of over 30 kW, but not more than 60 kW, can be installed in a room with an area of 13.5 m2. Equipment with a power exceeding 60 kW requires an area of up to 15 m2. Boilers with a closed combustion chamber can be installed in rooms of any size, starting from the established minimum value.
The ceilings in the boiler room must be high enough, at least 2.5 meters.
In a room with gas equipment prerequisite is the presence of a window, 30 cm of which falls on every 10 m2.
The door to the boiler room must have a width of more than 0.8 meters (read also: “Installation of a gas boiler room in a private house - requirements, standards”).
A gap of 2.5 cm should be provided between the top level of the door and the main opening.
Combustible finishing materials must not be used in the boiler room.
It is prohibited to install a false floor or false ceiling in a room with gas equipment.
There must be a hole for natural air flow. Moreover, for one unit of boiler power, at least 8 cm 2 holes are required.
It is necessary to supply water to the boiler room to install a double-circuit gas boiler.
Maintaining an optimal humidity value, since if there is excess moisture in the boiler room, the escape of gas vapor is difficult.
Installation of ventilation in the upper part of the boiler room. Read also: "".

Parts and pieces of equipment must also comply with the standards for installing a gas boiler in a private house:

Free access to the device from any side.
Use only metal gas pipes.
A gas meter is required.
Electric boilers require mandatory grounding.
Parallel installation gas analyzer and automatic valve. The first device will give a warning about a possible gas leak, the second will stop the gas supply if a leak is detected.

Chimney requirements

Installation of chimneys or gas outlets must be carried out in compliance with the installation parameters of a gas boiler in a private house:

Gas combustion products must be discharged through a separate channel.
The horizontal section of the chimney should be no more than 3 meters.
The chimney structure cannot have more than 3 elbows.
For a certain boiler power, a corresponding gas outlet diameter is required.
The cross-section of the chimney must correspond to the diameter of the hole to which the flue is connected.
The top point of the chimney should be located 0.5 meters above the level of the ridge.

Most modern boilers with a closed combustion chamber are sold complete with a coaxial chimney. Such devices can be installed in a room of any size, since combustion air is taken from the street.

The listed requirements for the installation of gas equipment, including the installation of a double-circuit boiler in a private house, may have additions and clarifications in accordance with the region of use. In addition, the gas supply may not be central, but bottled. Also, the rules may be adjusted depending on the material used to build the house and floors.

Design

All this leads to the fact that before installing a gas boiler, it is better to consult with a specialist who will inspect the structure and identify relevant shortcomings.

To obtain permission to install a gas boiler, you must do the following:

Write an application in the appropriate form to the organization that supplies gas. This document becomes a kind of permission to carry out preparatory construction work. In most cases, permission is issued no later than two weeks from the date of registration of the application.
After this, it is necessary to make a project; licensed specialists are engaged in its production.
Ready project subject to mandatory agreement with the gas supply organization. The complete package includes a statement project documentation and documents for gas equipment. Approval may take up to 3 months.

Installation in a private house

Installation of floor and wall equipment is carried out according to different schemes.

The technology for installing a floor-standing boiler includes the following steps:

Preparation solid foundation, capable of withstanding the weight of the boiler. Can be filled concrete screed or lay a sheet of galvanized iron.
Checking the level of installed equipment. The boiler must be positioned strictly parallel to the floor level.
Connecting to the gas outlet and checking the draft.
Connecting heating system pipes with the obligatory installation of a hard water filter. In addition, the installation of ball valves on all pipes and shut-off equipment on both sides of the filter is required.
When installing a double-circuit boiler in a private house, connect to plumbing system. In this case, the supply pipe should be located at the top, the return pipe at the bottom.
Connection to the gas pipeline. This item can only be carried out by a gas technician, independent work such plans are strictly prohibited.
Connection to the power supply network.

There are certain rules for installing a wall-mounted gas boiler:

Choose the strongest wall or partition and protect it with fireproof material.
Fix the boiler, maintaining a distance from the wall plane of about 5 cm. You should also retreat from other walls and the ceiling by 50 cm, from the floor by 80 cm. The boiler should be located parallel to the floor level.
Before installation, the walls of the inlet pipes should be cleared of debris by supplying water under pressure.
Install the filter on the water supply pipe. Install locking mechanisms on both sides of the filter.
Install a chimney, if provided for by the project, and check the draft.
Connect the device to the gas pipeline, inviting a gas service technician for this purpose.
Connect to the power supply.

Both options provide for filling the system with water before starting and first turning off the device. To avoid the formation of air bubbles, water must be introduced into the system very slowly.

In addition, the procedure for installing a gas boiler in a private house provides for temperature restrictions. Installation of a gas stake can be carried out at temperatures from +5 to +35 degrees.

Maintenance of gas boilers during operation

Gas equipment must be checked at least twice a year. Moreover, one of them falls on the period before heating season. Gas service specialists check the tightness of the chimney and its operability, condition ventilation system, perform maintenance and repair work.

Introduction

Wall-mounted gas boilers are very popular among owners autonomous systems heating. Since the fuel used in them is very explosive and toxic, it is necessary to approach the installation and commissioning of these devices with all responsibility. Installation of a wall-mounted gas boiler in a private house should be carried out in strict accordance with technical requirements and standards.

Installation in relation to wall mounted gas boilers, the concept is very comprehensive and can include such work as: correct choice of location and actual installation of the boiler on the wall, connection to the gas main, piping in the heating system. In this article we will exclusively consider issues the right choice premises and placement of the heating device on the wall, as well as existing requirements for carrying out this work.

Is it possible to install a gas boiler with your own hands?

Designing heating system you should take into account the requirements of gas services, which they impose both on the installation site of the wall-mounted gas boiler and on the installation process itself. If all technical requirements And building codes are met, some work can be done with your own hands.

Photo 1: Commissioning of a wall-mounted boiler by a gas service representative

It should be remembered that you are only allowed to independently place the wall-mounted boiler in the prepared room in accordance with the project developed by the gas service. Connection to the gas main and all commissioning work must be carried out by certified specialists authorized to carry out this work.

We also note that not all manufacturers allow the installation of gas boilers with their own hands. Many large companies producing gas heating equipment, such as Bosch, Ariston, Viessmann, will void the warranty on a wall-mounted boiler if the installation was carried out by an unqualified employee.

How to choose the right installation location?

Depending on the design, the installation requirements for wall-hung gas boilers are somewhat different. If installed heating device with a closed combustion chamber, it can be placed in almost any room of the house. For gas boilers with an open combustion chamber, the requirements are more stringent and a properly equipped boiler room should be provided for them. General requirements, presented by regulatory documents (SP 42-101-2003, SNiP 42-01, SNiP 31-02-2001, MDS 41.2-2000) and controlled gas services the following:

When installing household mounted gas heat generators with a power of up to 60 kW, the volume of the room in which the installation is carried out must be at least 15 m³. Mounted boilers with an open combustion chamber must be placed in a separate room on any floor of the building. Turbocharged heaters with a power of up to 35 kW can be installed in the kitchen.
The room in which installation is planned must have a ceiling height of at least 2.5 m. If a model with an open combustion chamber is used, it is required to equip it with another suitable material.
The boiler room or kitchen where the mounted boiler is installed must have a window with an area of at least 0.03 m² for each cubic meter premises.
When installing wall-mounted gas boilers with an open combustion chamber, it is important to ensure proper ventilation. The hood should produce three air exchanges in the room within an hour, and forced ventilation replenish the volume consumed by the hood plus supply the air necessary for normal operation burners.
The external gas pipeline is supplied directly to the room where the boiler is installed. The section of pipe passing indoors must comply with the requirements of SNiP 2.04.08 for low-pressure gas mains.
It is necessary to provide a connection point to the electrical network with grounding and artificial lighting. The temperature in the boiler room should be in the range from +5 to +35 °C with air humidity not exceeding 80%.

How to place a gas boiler on the wall?

Having correctly selected and prepared the room for installation, you need to determine the position of the wall-hung gas boiler on the wall and prepare the surface for installation accordingly:

It is recommended to install it on a solid wall that can support the weight of the device. If the wall is made of flammable material (for example, wooden house), then between the boiler and the wall there should be a gasket made of non-combustible material protruding along the perimeter of the device at a distance of 200 mm. Typically, a layer of asbestos cardboard is used, and a sheet of galvanized steel is attached on top of it.
It is recommended to install the mounted boiler at a height of 90-120 cm from the floor and at a distance of at least 10 cm from adjacent walls. This space is necessary for convenient strapping and service boiler
The socket for connecting to the electrical network should be located next to the wall-mounted boiler and in no case under it. This will avoid a short circuit in the event of a leak. A place should be provided nearby for.

The requirements for the location of gas boilers on the wall and the distance to various building elements differ for many models. We have given the most typical values, but still, before installation, you need to clarify them in the passport for a specific device.
