20.06.2020

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

A correctly installed floor-mounted gas boiler or 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 time-consuming process. It requires knowledge in the field of heat engineering, and also involves the use of special equipment and a whole list of auxiliary fittings. Since the device burns natural gas during the heating of water in heat exchangers, certain rules must be observed during installation that will reduce the risk of accidents and provide an opportunity to use a safe and reliable source of heating for a long time.

Before proceeding to the active phase of work, it is necessary to study the standards for installing a gas boiler in a private house, as well as coordinate actions with representatives of the relevant utility companies.

The property owner must have the following papers:

The basic rules for installing a gas boiler in a private house are general character. They involve 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 place to install the device in the house

Unlike residents of apartments, who face some problems when installing a heater, owners of private houses have much more 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 carried out in a furnace (boiler room). If a special room is not provided for by the project of a private house, then the owner can independently determine the place for drilling the brackets and fixing 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:

Requirements for the area of the premises and its layout may change, so each project is developed individually.

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

If specifications installations of a gas boiler in a private house stipulate the location of the device in a room of a certain area and require 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 model of the boiler 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.

Mounting the device

As you can see, before installing a gas boiler in a private house, the property owner has to do quite a lot of work. In the course of its implementation, an approved scheme for installing a gas boiler in a private house will be required, which regulates all further actions on the part of the installers.

Home distinctive feature wall heaters are their compact dimensions.

If a conventional floor boiler needs to be installed on a special pillow and at the same time take care of allocating enough free space around the device, then a wall-mounted analogue can be installed above other household appliances.

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 appliances and interior items. At the same time, flammable objects, doorways and windows should not be nearby. Also, a power source should be prepared in advance - the socket should be located near the heater, otherwise the owner will have to use a carrier.

When the installation site of the boiler is approved, the owner must check the completeness of the appliance. In the standard version, it is represented by the following elements:

Before the installation of gas boilers in a private house, the price of which is approximately from 5 to 15 thousand rubles, the owner will have to flush all the pipes and hoses that are clogged during the 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 planks are installed on the wall, the boiler is hung on them. The skew of the device is not allowed, so you need to take building level or a laser pointer, and make sure that the boiler is hung straight.

This is followed by the connection of pipelines to the corresponding nozzles of the boiler. It is advisable to install a filter equipped with shutoff valves for the water supply. You should also connect a pipeline to the boiler. Be sure to 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 autonomous system heating, often interested in the cost of installing a gas boiler in a private house, produced by employees of certified companies. Their services are used by clients who do not have the time or skills to self connection boiler.

It should be noted that the cost of services depends on various factors:

On average, installing a double-circuit gas boiler in a private house will cost real estate 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 manufacture of brackets and strobes, pipe laying, piping of a comb (collector), etc. The presence in the house will increase the cost of installation. 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 a homeowner. But the competent installation of the device is of great importance, and is no less responsible. Following the rules for installing heaters in private homes, the owner implements a reliable and effective system heating, which will work properly throughout the entire period of operation.

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

wall gas boilers can be located in the kitchen, in the bathroom, in any other premises.

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

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

a heat exchanger equipped with a burner and a device for controlling the operation of the unit;
expansion tank;
circulation pump;
security system.

To properly 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- and double-circuit. A single-circuit wall-mounted gas boiler is able to provide the house with heat, and a double-circuit one also 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 different installation features.

You need to understand that a wall-mounted gas boiler can be with an open or closed combustion chamber. So, in the first case, the removal of combustion products and smoke is carried out in a natural way. In a closed chamber, a fan is used for smoke extraction. For equipment with an open chamber, the combustion air is taken directly from the room. However, for correct operation such a unit, you need to follow a number of recommendations.

Before connecting a wall-mounted gas boiler to a previously installed chimney, you must make sure that it is clean, because. during operation, dirt can fall off and block the exit of combustion products. The connection of such equipment with an existing chimney must be carried out exclusively with the help of metal pipe resistant to mechanical wear and high temperatures, as well as aggressive environments like 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 must 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 in this case the removal of combustion products is carried out using a fan. Air for combustion is taken from the street. Such a boiler does not need to be connected to an individual chimney. The output can be carried out in a collective chimney or with the help of a coaxial chimney built into outer wall. The main thing is to ensure that no dirt gets into the fan installation site during installation. Be sure to check this place before starting 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 pipes of the chimney system. Pipes must be sloped down. 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 at a distance of at least 15 cm in front of the flue gas pipe there must be no different kind obstacles. Structures above the chimney must be located at a height of at least 25 cm. Otherwise, the flow of exhaust smoke will be disturbed, which may lead to incorrect operation of the unit or even cause emergency. And finally, you need to make sure that the chimney pipe is not clogged and does not hang out.

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.

All necessary actions and equipment installation scheme are coordinated there.

When buying a new gas boiler, be sure to check the completeness of the delivery. After unpacking, the unit must be in perfect appearance and must be accompanied by an instruction manual. If any part is missing, be sure to contact the suppliers and solve the problems that have arisen.

Need to check specifications indicated on the box of the device and on the boiler itself. In addition, you need to make sure that these indicators correspond to the numbers given in the boiler operating instructions. Before installing the equipment, it must be clarified whether the apparatus 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 all sorts of foreign particles. It is necessary to flush the lines of the heating system. The 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 consider the material from which the wall is made, and bearing capacity fasteners.

If the boiler is installed on a wall made of combustible materials, a sheet of non-combustible material with a thickness of at least 3 mm should be placed under the apparatus, 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 a separate wiring with a switch and a stabilizer. This system must be provided with grounding. The device must hang perfectly evenly on the wall.

Before execution installation work make sure there is sufficient 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 adjustment of the unit and all attached equipment must be carried out in the presence of an employee of the gas company.

Installing a wall-mounted gas boiler involves several logical steps. At the first stage, the purchase and delivery of the boiler, purchase required material You need a tool to install and assemble.

Material for installing a wall-mounted gas boiler

Installation of a wall-mounted gas boiler begins in the store. Of course, this is not the installation itself, but preparation for it. When buying or ordering a wall-mounted gas boiler, you need to find out or inspect whether the boiler is equipped with fasteners. Usually these are hooks and power dowels. If this fastener is not included with the boiler, it must be purchased.

It should be noted that "reputable" manufacturers of boilers complete the boiler with special installation patterns, according to which marking and drilling of holes for fixing the boiler is carried out.

Note: Let me remind you that when choosing a wall-mounted gas boiler and buying it, you must definitely be interested and require a certificate of conformity for the selected boiler model. Without this certificate, legalization (obtaining permission to connect) will be very problematic.

Gas wall hung boiler installation tool

For work, you need to prepare the following tool:

Electric drill or hammer drill. A drill is needed to drill holes for fasteners of a gas boiler.
Building level, more than 1 meter long.

The building level plays an important role in the installation of a gas boiler, and especially a condensing gas boiler. Any roll of a condensing gas boiler will lead to its failure in the shortest possible time. Not bad, replace the building level with a laser level, this will improve the accuracy of the installation.

Preparing the wall for the installation of a gas boiler

The room where the wall-mounted gas boiler will stand must meet a whole list of requirements for the furnace room. Often, wall-mounted gas boilers are placed in the kitchen and the place in the kitchen must be prepared for the installation of the boiler.

In addition to ventilation, ventilation and other rules, special attention should be paid to the wall on which the boiler will be placed.

The wall for hanging the gas boiler must be strong. The material or construction of the wall must be suitable for the installation of a load-bearing fixture on which the boiler will hang.
If the wall for hanging the boiler is made of plasterboard, then in advance in the frame of the plasterboard structure, it is necessary to provide and lay firmly fixed wooden blocks at the installation site of the fasteners.
If the material of the wall or its finish is potentially combustible, a non-combustible gasket from 3 mm thick and 10-15 cm larger than the boiler is installed between the wall and the boiler body.
According to the norms, a wall-mounted gas boiler should be 40-45 mm from the wall. Therefore, the gas boiler is not mounted on the wall, but on bars previously fixed to the wall.

Hanging a gas boiler on the wall

Mark the installation level of the gas boiler. Height from the floor from 800 to 1600 mm.
On the wooden wall fasten non-combustible material (asbestos) and a piece sheet metal(galvanized sheet).
Other types of walls, for an aesthetic installation of the boiler, veneer with ceramic tiles.
If the boiler is not equipped with a special bracket, install bars at the level of the gas boiler mounting in order to achieve the indentation of the boiler from the wall.
Mark the places for fixing the gas boiler. Usually, the packaging or instructions contain the exact dimensions of the boiler mounting points or an installation template. It is important to maintain the exact horizontal level of the gas boiler.

Important! The condensing gas boiler should be hung with a slight slope, “away from you”, that is, the distance from the boiler to the wall above should be less than the distance to the wall below.

Important to remember! Whatever material the heating system in the house (apartment) is made of, the boiler is connected only with metal pipes.

Preparing the gas boiler for hanging

Before the shed of the gas boiler:

The boiler is taken out of the package;
The marking plate on the boiler body is checked against the certificate and invoices;
The bracket included in the boiler kit, or other selected fasteners, is screwed to the mounting place on the wall;
All factory plugs are removed from the boiler;
It is MANDATORY to flush the system of internal pipes.
The gas boiler is hung in place.

After hanging, the horizontal position of the boiler is verified, if necessary, an adjustment is made. Everything! Hanging, or rather, the installation of a wall-mounted gas boiler is completed. The next step is to connect the gas boiler to the system.

Although there is today a large number of alternative sources heat, gas equipment is still in demand in this area. Gas boilers are able to supply the room with the necessary heat. At the same time, they can be installed both in an apartment and in a private house. In this article, we will consider the requirements for this process, and you will also learn that installing a gas boiler with your own hands is possible.

If the boiler has a power of up to 150 kW, then its installation is possible in any non-residential premises of the house, for example, a bathroom, a bathroom, a kitchen.
Boiler power from 150 kW and more is limited in the choice of location. A place for installation on the basement or first floor is allowed.
If the installation site is a kitchen, then 1 kW of its power should account for 0.2 m 3.
In the event of a gas leak, there should be a device in the room to shut off the gas supply.
After installing the gas boiler, all major components should be provided with sufficient access for maintenance.
As for the walls of the room, they must have a fire resistance level of up to 45 minutes.
There are also requirements for the cross section of the grille for ventilation. Calculations are taken for 1 kW of power 8 cm 2.

Separate requirements are also imposed on the chimney system:

The chimney diameter must correspond to the specified parameter in the boiler data sheet.
The pipe should be 0.5 m higher than the ridge.
The chimney should not exceed 25.
Up to 3 folds are allowed.
To clean the chimney, there must be special openings.
The chimney diameter must be equal to or greater than the chimney opening.

When installing the boiler in the kitchen, it is important to ensure the following conditions:

At a height not less than 800 mm from the floor.
There must be free space under the boiler.
It is recommended to lay a metal sheet under the boiler on the floor.

Before installing the boiler, you should have the necessary documentation that allows you to do this. In particular, a gas supply project is being created for your apartment or house. These documents are developed by the gas supplying organization. In the course of obtaining this documentation, you may be required to provide a package of documents that includes the fact that you are the owner of this living space.

The floor boiler has enough big weight. Therefore, first of all, it is necessary to prepare the surface where the wall-mounted boiler will stand. This includes the following:

The screed is poured onto the floor. The floor should be treated with non-combustible material. Make sure the surface is perfectly flat.
It is also desirable to cover the walls with non-combustible material. Otherwise, it is impossible to move the boiler close to the wall. It will be necessary to maintain a distance of up to 10 cm.

When all preparations are completed, the installation of auxiliary equipment is carried out. This includes:

Expansion tank.
Collector.
Hydrogun.
Boiler, etc.

Installation is much easier when there is a project on which all installation locations are indicated. On it, mark the walls, and then make holes for fasteners. Also installed equipment already at this stage, it is recommended to connect to the pipeline going to radiators or to underfloor heating.

If the boiler is already installed, it may be difficult to connect the equipment to the pipes. For this reason, it is better to carry out all these works before installing the boiler.

As for the installation of a floor-standing boiler in the house, first of all, it is necessary to screw the shackles and adapters on it, which are connected to the pipeline. Adapters can be of different diameters. For example, if a system with natural circulation, then thick pipes are brought to the boiler. If forced circulation, then the pipes and, accordingly, the adapters will be of small diameter.

Having moved the boiler to the prepared place, it should be connected to the chimney. Next, connect the security group and connect to the rest of the harness.

If you have ever hung cabinets, shelves and similar items, then it will not be difficult for you to install a wall-mounted boiler. The wall must be level and solid. In most cases, the boilers in the apartment are mounted on a mounting plate. It should be fixed to the wall at the desired height. Depending on the wall finish, it may be necessary to fix non-combustible material up to 3 mm thick on it. Also take into account the fact that the boiler should be hung at a distance of at least 20 cm from other equipment.

Modern wall boilers have a lower connection to the heating and water supply system. Therefore, after fixing the boiler to the wall, the boiler is tied.

Connection to the gas pipeline

After installing the boiler, it is also necessary to connect the gas pipeline. This stage of work should be done carefully, because you should not “joking” with gas. The connection includes the installation of a filter and a valve, which, if necessary, can shut off the gas supply. Next, a special gas hose is connected. But in no case should a rubber hose be installed. After a while, it will crack. Paronite gaskets are used to seal the threads. After tightening the hose nut, be sure to check it for a gas cut.

So, we have reviewed with you the basic rules for installing a floor and wall-mounted gas boiler. You can share your experience about the work done in the comments to this article. You can also see installation diagrams in the corresponding section.

In this video, you will learn about the intricacies of installing a wall and floor boiler:

In a modern private house, a gas boiler is indispensable. It is simple and safe to operate. Yes, its installation is very time-consuming and expensive, but in the end, a gas boiler is the most cost-effective solution for heating a house and heating water. Compared to electric heaters, it can pay for itself in one winter.

Gas boilers can be single-circuit and double-circuit. Single-circuit are intended only for heating, double-circuit - for heating and water heating. Also, gas boilers differ in power and type of installation.

It's very important to get it right determine the required power equipment. The disadvantages of insufficient power are obvious. Excess power, in addition to the economic component, is also dangerous. Acid condensate is formed in the combustion chamber from frequent temperature changes, which can corrode metal parts boiler.

The power of the boiler is directly dependent on the size of the room. You also need to correct for climatic conditions in which you live. Divide the area of heated premises by 10, and multiply by a factor of 1.2 - 1.5 for the Moscow region, 0.7 - 0.9 for the southern regions, 1.5 - 2 for the northern regions - and you will get the required power. Thus, for a house with an area of 100 square meters, located in the Central region, requires a device with a capacity of at least 12-15 kilowatts.

The power can be adjusted. Low-power boilers have a single-stage power control. Heating devices of average productivity are equipped with two-stage adjustment. High-performance boilers are equipped with modulated power control.

According to the type of installation, wall and floor boilers are distinguished. Each type of installation has its own characteristics. But, no matter what boiler we install, before its direct installation, a number of requirements must be met that are established by certain SNiPs.

For devices that are installed on the territory of the Russian Federation, the requirements are determined by SNiP 41-01-2003 "Heating, ventilation and air conditioning", SNiP 31-01-2003 "Residential and multi-apartment buildings", SNiPOM 42-01-2002"Gas distribution systems" and other governing documents.

Rules for installing gas boilers in a private house

room

Requirements for parts and equipment parts

Gas outlets (or, as they are often called, chimneys)

The passage for the removal of combustion products must be separate from a conventional chimney.
Horizontally, its length in the boiler room should not exceed three meters.
The gas outlet can have no more than 3 elbows.
The diameter of the gas outlet and the power of the boiler must correspond (for power up to 30 kW D=130 mm., for power 40 kW D=140 mm.)
The diameter of the gas outlet must not be less than the diameter of the hole for connecting the gas duct.
The outer end of the gas outlet must be at least half a meter above the roof ridge.

V modern boilers with a closed combustion chamber, the so-called coaxial chimneys, which are sold and installed together with the heating device. When installing such boilers, the dimensions of the room are also not important, since the combustion air does not come from it, but from the street.

These General requirements may differ slightly in different regions They are constantly being developed and refined. In addition, there are nuances that the gas supply in the house is not central, but bottled. At the same time, the rules and requirements for installing a gas boiler will differ in some features. There is a difference in what material the house is built from, what are the floors. In order to avoid problems at the project approval stage, it is better to invite a specialist and inspect the house in advance for possible shortcomings.

What actions need to be taken for obtaining permits for the installation of a gas boiler:

Agreed project and is permit document to install a gas boiler.

Installation

The installation sequence of the floor boiler

The boiler is installed on a solid base that can withstand its weight. To do this, either fill concrete screed or a sheet of galvanized iron is laid on the floor.
When placing the machine on a base, make sure that it is exactly parallel to the ground.
Connect to the chimney and check the draft.
Connect with pipes heating system, while installing a hard water filter (after the outlet line before entering the return line boiler). On both sides of the filter, put shut-off mechanisms (for example, ball valves). Ball valves install on all pipes.
Double-circuit boiler connect to plumbing. It is better to make a tie-in into the water supply system as close as possible to the entrance of the pipe into the building or to the point of branching of the pipe. It is better to connect the water supply pipe from above, the water return pipe - from below.
Connect to the gas pipeline. This can only be done by a master gasman; you cannot make a tie-in yourself.
Connect to power supply.

In both installation variants, the system must be filled with water before the first start-up. To do this, the device must be turned off. Water should be drawn in very slowly - this is the only way you will get rid of air "bubbles" in the heating system.

It should also be remembered that the installation of any gas equipment can not be produced at sub-zero temperatures, the temperature must be from 5 to 35 degrees.

Maintenance of gas equipment

Gas appliances should be serviced regularly, at least twice a year. Be sure to do this before you start. heating season. The specialist must check the tightness, condition of the chimney and ventilation system, clean the filters and the burner, replace worn parts.
