home » Apartment renovation Gas boilers outlet. Electric heating boilers: environmental friendliness and ease of operation

Electric boilers are one of the types of heating equipment, which is the basis of autonomous heating systems. The principle of operation of electric boilers is based on the conversion of electricity into heat. In this case, electric boilers can be divided into two main types, these are indirect and direct heating devices. Indirect heating boilers include devices equipped with an electric heating element, with the help of which the working fluid is heated. In addition, in such boilers, instead of a heating element, electromagnetic induction technology can also be used, which provides heating of the coolant. In turn, the preparation of liquid in direct-action electric boilers occurs by direct heating of the coolant due to special electrodes.

It is also worth noting the difference in the power of the boilers, which, depending on the modification, can be from 3 to 60 kW, which in turn determines the type of power supply of the equipment presented, which can be single-phase (220 W) or have three phases (380 W) at a frequency of 50 Hz. That is why, when choosing electric boilers, it is worth considering not only consumption indicators, but also the maximum permissible load indicators on the power grid. In addition, the assortment of most modern manufacturers includes both single-circuit and double-circuit models intended for organizing not only heating systems, but also hot water supply. Moreover, depending on the model and brand of the manufacturer, electric boilers can be equipped with various electronic control interfaces that simplify their operation and maintenance.

Despite such a technical variety of modifications of electric boilers, they have a number of common advantages over their counterparts. First of all, it is worth highlighting the versatility, since these devices can be used at objects of any purpose, be it residential or industrial premises. In addition, unlike gas or diesel analogues, the presented equipment has a more affordable price, and the efficiency of these devices can reach up to 99.5%, which in turn has a positive effect on their energy efficiency. In addition, the simplified installation and operation of this equipment eliminates the need for installing a chimney system, loading fuel and cleaning, and full automation does not require daily adjustment and control over the operation of the boiler. It is also worth noting the noiselessness and absolute environmental friendliness in the operation of this equipment, since the electrical modifications of the boilers do not emit combustion products, which allows them to be installed even in residential premises. In conclusion, it should be said that in addition to the main source of heat, electric boilers are often used as a backup in combination with gas or solid-fuel counterparts.

The most cost-effective fuel today is natural gas. Modern boiler equipment, equipped with automation, allows you to reduce the risks of gas leakage and explosion to almost zero. At the same time, it is important that the installation of a gas boiler in a private house is carried out taking into account all safety requirements.

Installing a gas boiler in a private house

Installation standards

The room in which the heating boiler is supposed to be mounted must comply with the standards specified in SNiP. For single-family and block houses, the installation rules are specified in SNiP 31-02-2001, installation of gas heating units in apartments in apartment buildings regulated by SNiP 2.08.01. Residential buildings.

It is also helpful to study the information provided in the following documents:

SNiP 2.04.08-87 "Gas supply";
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";
SNiP 42-101-2003 " General Provisions for the design and construction of gas distribution systems from metal and polyethylene pipes. "

Coordination and design

Installation of gas equipment is carried out according to the prepared project. And for its development, it is required to obtain the technical conditions for the installation (TU) by contacting the appropriate authorities.

It is forbidden to carry out installation work until the corresponding project has been drawn up, agreed and approved

The homeowner submits an application to the local organization, whose function is to supply the main gas to the population. This is Gorgaz or Oblgaz. In the application, it is required to indicate what gas consumption is planned for heating, preparation of hot water, cooking, etc. In this case, they proceed from the heated area of the house, the need for hot water etc. Calculations are performed according to the average indicators given in SNiP 31-02, clause 9.1.3.

Specialists of the local gas supply organization consider the application and prepare documents on the technical conditions for the connection (or write a reasoned refusal). It takes from one week to a month.

Technical conditions are a permission document for connection, which at the same time strictly regulates the work. Unauthorized (without obtaining technical specifications) installation of gas boiler equipment is prohibited by law.

The project for connecting the house to the central gas, the equipment installation scheme, should be developed by professionals licensed for this type of work. You can contact the design department of Gorgaz or Oblgaz, or use the offer of a licensed commercial company. The second option is much more expensive, but the project will be ready and approved in a short time.

Requirements for private houses

The current rules and regulations provide for the installation of a gas boiler unit in a room with sufficient ventilation, located:

on the 1st floor of a private house;
in the basement or basement;
in the annex;
in the attic;
in the kitchen - with power restrictions: only up to 35 kW (according to MDS 41.2-2000, installation of boilers up to 60 kW is allowed).

Note! There are two norms regarding the installation of a heating unit in the kitchen. Since the installed unit will be commissioned by the local gas service, at the design stage of the heating system, ask what rate this organization took as a basis.

Choosing which room to put the boiler in, you should take into account the power limitations:

150 kW and more - a separate room is suitable, regardless of the floor location;
151kW - 350kW - in the annex, on the first or ground floor, in the basement.

If, in addition to the boiler unit, it is planned to use a geyser, the capacity of the equipment is summed up. It is not allowed to install more than two heating units in one room.

Requirements for the room for the installation of a gas boiler

Requirements for kitchens

If you plan to install a heating unit with a power of up to 60 W in the kitchen, check that the room meets the current requirements and regulations. First of all, calculate the required volume: add one cubic meter to 7.5 cubic meters for each kW of the rated power of the boiler equipment. In this case, the ceiling height must be at least 2.2 meters.

Also required:

high-quality ventilation - the inflow must compensate for the air consumption for gas combustion in an open-type firebox; an exhaust hood is required, the capacity of which is at least three times the volume of the room;
a window with a vent, while with a glass thickness of 3 mm, the glazing area must be at least 0.8 m 2, respectively, for a glass thickness of 4 mm this figure is 1 m 2, for 5 mm - 1.5 m 2.
clearance under kitchen door with an area of 0.25 m 2 or a hole of the same area in the lower part of the door, covered with a grill.

Double-circuit wall heater in the kitchen

Important! If an arch is located between the kitchen and the adjacent room instead of a wall with a door, or if both rooms are combined due to the demolition of the partition, the controlling organizations may not allow the installation of a gas unit in the kitchen. In some cases, the installation of sliding, folding or glass doors will help solve the problem of obtaining a permit.

Separate rooms for the boiler room

The requirements for the room in which the gas boiler will be installed are similar to the requirements for the kitchen, but there are a number of differences. The boiler room must have the following parameters:

ceiling heights from 2.2 meters;
the volume of the room is not less than 15 m 3, it does not depend on the power of the boiler unit, the main thing is to ensure the convenience of its maintenance;
non-combustible material for the manufacture or decoration of walls leading to adjacent rooms (fire resistance limit of 0.75 hours, non-propagation of fire along structures);
extractor hood with triple exchange for outflow and with the same inflow and additional air volume for operation of the boiler atmospheric burner;
the presence of a window, while the area of glass should be from 0.03 m 2 per cubic meter of the volume of the room. If the glazing area is insufficient and it is not possible to enlarge the window, an additional window is performed during front door.

The area of the furnace room depends on the power of the gas boiler

A boiler room designed for the installation of gas equipment for heating and heating water with a total capacity of over 150 kW must have an exit to the street. If there is a second exit, it should lead to a non-residential premises - to a corridor, a closet, etc. Installation of fire doors is required.

Extension equipment

If there is no suitable room to install a gas boiler in a private house, a special extension is erected outside. With regard to cubic capacity, ceiling heights, glazing and hoods, the requirements for it coincide with those prescribed for individual rooms in the house. But besides this, other norms must be observed.:

an extension for a boiler room is erected only at a solid wall, at a distance of at least one meter from a door or window opening;
for the construction of walls, non-combustible material is used (withstand 45 minutes before ignition, does not spread combustion), which include building blocks of various types - brick, concrete;
the wall structures of the extension should not be connected to the wall of the house - a separate foundation is set up for the structure, and all four walls are erected.

Schematic representation of the extension of the boiler room to the house

Note! The extension must be officially registered. Without an appropriate document, gas services do not have the right to allow gas supply to it. During the design and construction phase, make sure that the extension meets all applicable regulations, otherwise the gas connection will be refused.

General requirements for a boiler room

The rules for installing a gas boiler regulate the arrangement of the boiler room. In particular, it requires:

the width of the door leaf - from 0.8 m;
the gap between the doorway and the boiler is 1.3-1.5 m (at least 1 m);
free space in front of the boiler unit - from 1.3 m (for the convenience of installation work and further maintenance);
floor made of non-combustible material, solid, strictly horizontal surface;
separate foundation for heavy floor models;
the presence of sewerage and water supply (for filling and flushing the boiler, the heating system circuit);
the presence of electrical wiring with grounded sockets (for connecting volatile automation of the boiler unit);
the presence of a chimney and free access to it (to the inspection window) for the purpose of monitoring and preventive cleaning work.

Options for placing a gas heating unit in the house

If the walls of the boiler room are made of combustible material (wood), they must be lined with fire-resistant material.

Ventilation and chimney

The installation of ventilation and a duct for the removal of combustion products must be carried out in compliance with SNiP standards, since their ineffective operation can damage the boiler unit, provoke an emergency. The ventilation and smoke exhaust ducts must be separate.

The inlet for supply ventilation is located at the bottom of the door or at the bottom on outside wall... Its area should be from 1/30 of the total area of the room, while if the ventilation hole goes out into the street, its area should be from 80 mm 2 per 1 kW of heating boiler power, and if the window leads into the room, then from 300 mm 2 to 1 kW. The ventilation holes are always kept open to maintain effective air circulation.

If it is planned to install mechanical ventilation in a gas boiler room, the requirements for it should be clarified at the design stage. In any case, the system should provide three times the room air renewal within an hour.

Chimney outlet from a wall-mounted gas boiler with a closed combustion chamber

The boiler must be installed as close as possible to the flue duct, the exhaust opening of which must not be less than the cross-section of the flue pipe of the heating unit. For the manufacture of the chimney, low-carbon or stainless steel is used. Pipes made of asbestos concrete and other materials are not allowed to be connected directly to the branch pipe - the distance between the boiler outlet and such a pipe must be at least 50 cm. No more than three turns or bends of the chimney are allowed.

Attention! It is optimal to use a sandwich pipe, which is assembled from prefabricated elements.

The correct operation of the boiler directly depends on the draft. Calculate the height and install the chimney in such a way that its head is located outside the zone of the wind support. Accordingly, the height of the pipe:

on a flat roof - at least 50 cm from the parapet (if available) or the flooring plane itself;
on pitched roof, at a distance of up to 150 cm from the ridge horizontally, - not less than 50 cm;
on a pitched roof, at a distance of 250-300 cm horizontally from the ridge - no less than the height of the ridge;
on a pitched roof, at a distance of more than 300 cm horizontally from the ridge - the head is placed on a conditional line, which is drawn at an angle of 10 ° to the horizon from the upper point of the ridge.

Wall-hung boiler installation

Wall-mounted units of low power may be placed outside a specially equipped boiler room, while they are prohibited from being mounted in residential premises and bathrooms.

It is convenient to mount a compact heating unit in the kitchen if it meets all the requirements. This room already has water supply, sewerage, electrical wiring, there is or will be a gas pipeline. In this case, you should pay attention to the following requirements for the installation of a wall-mounted gas boiler:

the space under the boiler unit must remain free;
a wooden or frame wall of the house must be protected with a screen made of non-combustible material;
the distance from the rear wall of the boiler to the fireproof wall is from 2 cm, from the protective screen - from 3 cm;
distance from side walls - 10 cm for non-combustible, 25 cm for unprotected hard-combustible and combustible.

Installation of a wall-mounted double-circuit gas appliance

SES standards prohibit the use of asbestos in residential premises, therefore, to protect wooden or frame wall you can use mineral fiber cardboard, tiling, a layer of plaster 3 cm thick. The screen should exceed the dimensions of the boiler wall by 10 cm from the bottom and sides and 70 cm from the top.

Standard mounts are mounted on the wall, the boiler unit is hung on them. The chimney is connected to a pre-assembled chimney. Connect the power supply for the automation (the socket must be grounded). Connect the pipes of the heating circuit. Gas connection and commissioning are performed by specialists of the relevant service.

Installation of the floor-standing unit

Consider how to properly install a floor-standing gas boiler in a specially equipped room. At the design stage of the boiler room, it is envisaged to arrange a separate foundation for a high-power boiler. The foundation is made of reinforced concrete and must be strictly horizontal. This avoids vibration and noise during equipment operation.

If a room on the first floor of the house is allocated for the boiler room, and the floor in it is wooden, it is necessary to prepare a flat non-combustible base. Suitable for this brickwork on a spoon (flat on the wide side) or laying thick ceramic tiles (a "sandwich" of metal and then an asbestos sheet is placed under it, which is glued to the metal). The size of the base is selected depending on the dimensions of the boiler - on each side it should protrude at least 10 cm.

Installation diagram of a floor-standing gas boiler

If the wall of the house behind the boiler is made of combustible or non-combustible material, it is recommended to protect it according to the same principle as in the case of installing a wall-mounted heat generator.

After the base has gained strength, you can put the boiler back in place and connect it to the chimney, to the heating circuit. The double-circuit unit is also connected to the hot water supply system. Power supply for automatic devices.

After completing the installation of a floor-standing gas boiler, you should call the representatives of the gas service. Specialists without fail check the compliance of the premises and equipment with the requirements of TU. If everything is in order, the equipment is connected, commissioning and a contract for the provision of gas supply services is drawn up.

Position

So, let's talk about the design of systems and the distance of the pipes of the system from various objects.

To do this, let us clarify that, according to SNIP, there are two types of gas pipeline:

underground;
outer.

Each of the types has its own distance norms, we will consider them in more detail.

Underground

Distance from home to gas pipe in the embankment cannot be less than 5 m. There are special provisions of the SNIP, according to which the distance can be reduced by 50%, but they are regulated by the peculiarities of the terrain and the passage of the gas pipeline. For example, laying pipes between houses, arches, in very limited areas, etc.

The distance to the gas pipe of the outer walls of the well, chambers or other equipment of engineering networks should not be less than 30 cm. The laying must be carried out in compliance with the technical requirements and conditions. Only this can be a guarantor of security. By the way, that is why the independent transfer or organization of the gas supply system is not allowed.

The distance to air communication lines, as well as electrical external networks, cannot be less than 2 meters. The same applies to the gap between the gas pipeline and the heat transfer channels. The distance from the gas pipe to the fence, taking into account the underground laying of the highway in the villages, should be at least 50 meters. SNIP provides for a reduction in the gap, but only when taking into account certain norms prescribed in the regulations.

The depth of the gas pipeline should be more than 0.8 m for highways and roads with heavy passenger traffic, and 0.6 m for low-traffic roads.

Ground and above ground

Overhead wires are laid along the facades of buildings, on special supports made of materials that do not burn.

The place of installation depends on the pressure of the gas pipeline:

up to 0.6 MPa - wiring is allowed on stacks and overpasses, as well as columns, supports and along the walls of industrial buildings;
up to 0.3 MPa - laying on the walls of residential buildings and public buildings not lower than the 3rd degree of fire resistance is allowed.

It is prohibited to lay gas pipelines of any pressure for the purpose of gas transit, according to SNIP:

on the walls of kindergartens and schools, hospitals and companies that imply a large crowd of people;
for buildings in which the walls consist of panels and have a metal sheathing with polymer insulation;
for buildings of category "A" and "B".

It is prohibited to carry medium and high pressure gas pipelines along the walls of residential buildings. Also, you cannot lead a transit gas pipeline through window openings.

In areas near the ground, pipes must be enclosed in a special case. The horizontal distance to the gas pipe from the ground cannot be less than 35 cm.

The distance from the gas pipe to the chimney must be more than 2 meters from the outside and at least one meter from the inside of the building. However, this indicator depends on many factors, for example, location, conditions of gas wiring and pipe configuration, etc.

In room

It is very important to comply with the technical conditions in the room, since it is often the domestic non-compliance with the norms that is the cause of gas emergencies. In most cases, polyethylene gas pipes are used in apartments and private houses. Usually they go exclusively to the gas stove or oven. But some houses have autonomous gas heating. And here a special boiler is already being used.

In this case, the floor from the pipe must be at least 50 cm away. The same distance from the wall to the boiler. The vertical distance to the chimney should not be less than 80 cm inside. The same distance of the pipe to the cooking plate. The distance from the pipe to the outlet in a small room should not be less than 30 cm.

Safeguarding a building means safeguarding life. That is why it is important to comply with the rules and regulations specified in the SNIP.

Why keep the distance between the outlet and the gas pipe

Usually, an AC outlet of 220 volts for powering electrical appliances and gas pipes is located in the immediate vicinity of the kitchen or at the connection point of the gas heating boiler of an individual house. A typical failure of an electrical outlet is the loosening of the fastening screws on the terminal block during operation, as a result of which the wire moves away from the terminal plate a short distance and a spark may appear between them.

If at this time a long-term gas leak occurs from the gas pipeline for some reason, then when it reaches a certain concentration after entering the sparking zone, an explosion may occur. A similar danger is posed by sparking not only in the outlet, but also in the rupture of electrical wires, connected electrical devices, shields placed next to the gas pipe.

It is clear that the closer the laying of electrical lines to gas pipelines, the greater the risk of explosion is a combination of such unfavorable factors as sparking and gas leakage.

Fig. 2 An example of the location of a kitchen outlet, taking into account a safe distance from gas pipes

Rules for the placement of pipes and sockets in relation to the gas pipe

Often the cause of emergencies and emergencies is a violation of the simplest safety rules for the installation of electrical wiring, one of which is the norms for the distance of electrical wiring relative to pipelines.

The set of rules for electrical installations (PES) developed by specialists from the Ministry of Energy allows to fully answer the question: at what distance from the gas pipe can a cable be laid and an electrical outlet installed.

Distance from the electrical outlet to the gas pipe - how the norms are regulated

The rules for safe installation of electrical wiring are regulated by the main regulatory document - PUE-6, they apply to installed and operated electrical installations with an alternating current voltage of up to 750 kW. The rules have been developed taking into account the implementation of planned and preventive tests, repair of electrical installations, over which technical supervision has been established.

The distance from the outlet to the gas pipe is established by the normative act of the Ministry of Energy PUE-7, clause 7.1.50, which regulates the clearance between electrical switches, electrical outlets and the gas pipe not less than 500 mm.

Rice. 3 Selection criteria and methods for laying exposed electrical wires and cables

Rules for the placement of pipes and electrical cables

When installing electrical networks, internal and external wiring is distinguished; in the first version, it is placed in the structure (grooves) or niches of building structures and is separated from the surface by non-combustible materials - concrete, plaster, cement-sand mortar, alabaster, gypsum binder. The thickness of the insulating layer of hidden wiring made of non-combustible building materials is regulated by PES only for cases of nearby products made of combustible components, according to the rules, the insulator layer should not be less than 100 mm.

PES regulate in more detail the norms for the distances of open wiring to pipes through which explosive gases circulate. At the request of regulatory documents (PUE-6 clause 2.1.56), the permissible distance in the light between electric wires without protection or in protective insulation and pipes with neutral substances must be at least 50 mm. If an explosive gas passes through the line, the clearance is made more than 100 mm ...

If the distance from the electric cables to the pipes is less than 250 mm, the wiring must be protected from mechanical stress for a length of at least 250 mm on both sides of the gas pipe.

With parallel laying of an electric cable and pipes with a neutral working substance, the gap between them is made at least 100 mm. If electric line runs next to the gas pipeline, the distance between the gas pipeline and the wire must be more than 400 mm.

If the design of the room includes the intersection of laid hot pipelines with electrical wiring, the latter must have a suitable heat-resistant insulation performance or have external protection against high temperatures.

Rice. 4 Methods of installation of electrical wiring depending on the type of premises

When carrying out repair work in an apartment, a situation often arises when you need to move the electrical outlet in the kitchen or lay new wiring. In this case, electrical installation work must be carried out in accordance with generally accepted requirements and rules (PES) developed by specialists, taking into account the repeatedly tested safety standards.

Preparations for boiler installation - regulations and project documentation

For a competent installation of a gas boiler in a cottage, in a country house or in a private house, you must first familiarize yourself with the existing regulatory documentation governing the rules for performing such work. The norms describe the features of the installation of gas equipment to create an autonomous heating system.

First of all, you should study SNiP 31-02-2001 on gas supply country houses... All legal requirements for the installed gas equipment are listed here. In addition, information on the requirements for the device of an autonomous heating system is also contained in the documents:

SNiP 41-01-2003 on ventilation, heating and air conditioning;
SNiP 2.04.01-85 on the internal water supply system;
SNiP 21-01-97 on fire safety;
SNiP 2.04.08-87 on the boiler room arrangement.

According to these requirements, in order to install a boiler in a house, you must first obtain technical conditions, which are the basis for organizing connection work home equipment to the central gas supply line. To obtain a technical specification, you need to contact the local gas service and submit an application indicating the estimated gas consumption for heating needs. In central Russia, gas heating consumes from 7 to 12 m 3 of gas per day.

The submitted application will be considered by the company's specialists, if it is possible to organize the connection, the owner will receive technical specifications, but if for some reason it is impossible to supply gas to the house, the owner of the facility will be given a reasoned refusal. The procedure for considering the application takes place within one month, but the owner can receive a response much earlier.

The technical conditions are the official permission for the installation of gas equipment. Performing work without technical specifications is considered illegal and dangerous for home users.

Having received the technical conditions, you can proceed to create a project to connect the facility to gas supply. The project should include a scheme for the installation of gas communications - gas supply pipes from the central highway to a private land plot and from the point of connection of the plot to the inside of the house.

Gas supply design is allowed only to qualified specialists who have all the relevant permits and licenses to perform such work. It is impossible to prepare a project for connection to the network on your own. The finished project is submitted for approval to the department of the organization that controls the gas supply in the village. Approval is carried out within 90 days from the moment the owner submits an application.

When submitting an application for project approval, the following documents must be attached to it:

technical passport and instructions for using the installed boiler;
certificates of conformity;
confirmation of compliance of the gas unit with safety requirements.

If, for some reason, the gas service decides to refuse the owner to approve the project, he will be given a reasoned refusal and a list of actions necessary to obtain permission to connect the house to gas supply and install gas equipment.

The question of household electrical appliances, electrical equipment of household appliances, as I understand it. Of course, I am not an electrician, but as I understand it, electrical equipment is component refrigerator or other appliance. Maybe someone will correct, not strong in definitions for electrical.
Regarding electrical installations, there are standards, but from refrigerators, microwaves, etc. Do not know
In accordance with PB clause 8.3.1. The premises in which the equipment of the gas supply systems of the gas turbine and the CCGT unit is located should be classified according to the explosion hazard to the zone of class B-1a, the space near outdoor installations - to the zone of class B-1g.
Explosive zones should also include the space within 3 m horizontally and vertically from the valves and flange connections of pipelines.
There is always an armature in front of the meter, so that at least 3m. And what, we all have such kitchens so that at least 3m to place all email. devices from a gas meter, taps?)))
And acc. with PUE too:
7.3.44. For outdoor explosive installations, an explosive zone of class B-Ig is considered within the range up to:
a) 0.5 m horizontally and vertically from openings behind the external enclosing structures of rooms with explosive zones classes B-I, B-Ia, B-II; -not our case.
b) 3 m horizontally and vertically from a closed technological apparatus containing flammable gases or flammable liquids; from an exhaust fan installed outside (on the street) and serving premises with explosive zones of any class;
c) 5 m horizontally and vertically from devices for discharging from safety and breathing valves of tanks and technological devices with flammable gases or flammable liquids, from devices located on the enclosing structures of buildings for discharging air from exhaust ventilation systems of rooms with explosive zones of any class;
But you can also retreat 5m, as in this paragraph, so that for sure)))))
So back off 0.5m and that's enough.

Advantages and disadvantages of using gas-type boilers

The high popularity of gas heating equipment, which, subject to certain requirements for the premises, can be installed in the kitchen, is due to a number of reasons. These include:

long service life;
high reliability of boilers of this type;
the possibility of using for heating rooms with a large area;
sufficiently high efficiency;
the ability to choose a model from a fairly large assortment in a certain design and with the required set of options;
ease of operation, management and maintenance;
availability and low price of the used energy carrier - gas;
rather low cost of equipment.

Meanwhile, gas equipment also has disadvantages, which include the following parameters.

Such equipment can work only if there is gas in the pipeline connected to it.
It is possible to install such equipment in a private house or in the country only if the appropriate permission has been obtained for this.
If the gas pressure in the pipeline drops, then this leads not only to a decrease in the efficiency of the boiler, but also to the formation of a significant amount of soot during its operation.
Quite a high complexity of installation of both the boiler itself and the chimney and ventilation system.

Varieties of gas heating equipment

Modern industry produces a fairly wide variety of types of equipment for equipping a gas boiler house or for installation in any other non-residential premises, which allows users of such devices to optimally select them in full accordance with their requirements and financial capabilities. So, depending on a number of parameters, boilers can be:

single-circuit or double-circuit type;
with a closed or open combustion chamber;
equipped with various ignition systems;
with a boiler for heating water of external or internal type;
floor-mounted or wall-mounted.

In addition, of course, heating appliances for the kitchen differ in their power.

Differences between single and double-circuit gas boilers

Single-circuit and double-circuit boilers for the kitchen differ not only in the number of circuits in their design, but also in functionality. So, a single-circuit type technique can be used only for heating, and a double-circuit gas boiler can also be used to heat water for domestic and household needs. Meanwhile, if you equip a single-circuit boiler with an external boiler, then it can also be used to heat water for hot water supply in the kitchen.

Gas boilers with closed and open combustion chambers

The air in boilers with an open combustion chamber comes directly from the kitchen, and the exhaust gases escape naturally through the chimney. Installation of this type of boiler in the kitchen is not the best way, since when it works in the kitchen, the amount of air decreases, which is especially critical if the volume of the room is small. Boilers with a closed combustion chamber operate on a slightly different principle, the air into which is supplied from the street through a special coaxial-type chimney and the gases formed during combustion are also discharged through it. The installation site for a boiler with a closed combustion chamber can even be small kitchens (6–8 m 2), where they can be installed inside kitchen furniture cabinets.

Differences between gas boilers by type of ignition

Heating devices, depending on the model, can be equipped with automatic and manual ignition systems. In devices of the first type, the burner automatically turns on at the moment when gas begins to flow into it, and when using the type with manual ignition, accordingly, such a process will have to be carried out independently, using matches or a lighter.

Gas boilers with external and built-in boilers

Naturally, it is much more convenient when, together with a gas boiler, a boiler is also used, in which water is heated, intended to satisfy domestic and household needs. Such boilers for the kitchen, as mentioned above, can be external and built into the boiler itself. Devices with built-in boilers are compact in size, such options are easier to install, but the volume of the tank that is built into them is quite small. Almost anything can be the volume of the tank for boilers with an external boiler, but such devices, which should be taken into account when choosing them, take up more space, and in order to carry out their installation, it will be necessary to equip additional communications.

Rules for installing a gas boiler in the kitchen

In order to put the boiler in the kitchen and not have problems with such equipment in terms of its operation and maintenance, you should strictly adhere to the requirements specified in SNiPs. These requirements for the installation of a gas boiler, which should be adhered to when replacing an old device with a new one, stipulate a number of parameters, which include: the location of the equipment in relation to plumbing fixtures, windows and hoods; the distance at which the side walls of the device should be located from the walls of the room; installation height of a wall-mounted gas boiler from the floor, etc.

According to the above parameters, the installation of a gas boiler in the kitchen is allowed if the kitchen is not used as a living room.

The most common today are two ways to install gas equipment in the kitchen:

Installation of a gas appliance in a special box, which, in turn, is mounted in one of the pieces of furniture in the kitchen. Having decided to choose this option, it should be borne in mind that the installation of the boiler in the kitchen in this way, according to safety requirements, is not possible in all cases.
Installation of a boiler equipped with a decorative front panel. This is convenient, since a wide variety of gas boilers with different options decorative finishing, which makes it possible to optimally select a boiler for almost any interior.

Basic requirements for the installation of gas heating boilers in the kitchen

The layout and equipment of the kitchen, if it is planned to place a gas heating boiler in it, should immediately provide for the requirements for the installation of such equipment. Such requirements, in particular, determine the following parameters of the kitchen:

The presence of a door in the kitchen, which is necessary to isolate it from the living quarters of the house.
The presence of a window opening in the kitchen and its dimensions. The requirements for this parameter are minimal.
Supply and exhaust ventilation in the kitchen.
The presence of electrical sockets and gas supply pipes in the equipped kitchen and the distance from them to the installed heating boiler.
The presence of a smoke evacuation system in the kitchen.

It should be borne in mind that the requirement regarding the presence of a door in the kitchen in which the gas boiler is installed is very important, since the room in which such equipment is used must be isolated from living rooms.

In addition, it is very important to leave a certain distance from the wall of the boiler itself to the wall of the room, since the air around such equipment must circulate freely, which is very important to ensure the safety of its use.

The presence in the kitchen, in which the gas boiler is installed, vents and ventilation systems

The list of requirements related to kitchen rooms in which a gas boiler is used clearly states that windows that are installed in such rooms must be equipped with vents without fail. Thus, according to this requirement, if metal-plastic windows are installed in the kitchen room, in which there are no vents, then this is a violation of safety standards. Meanwhile, in the overwhelming majority of cases, representatives of gas services do not pay attention to such a violation of requirements.

The need for a vent in the windows of a kitchen room equipped with a gas boiler, as well as a convection hole in door leaf, is explained by the fact that the air in such a room must constantly circulate so that a high concentration of volatile substances hazardous to human life is not created in it.

In the event that the gas boiler will be mounted in the inside kitchen cabinet, then you should be especially careful to ensure that such equipment is located in the path of the movement of air currents in the kitchen. In addition, with this option for placing a gas boiler, it is necessary to provide for the presence of convection holes in the doors of the kitchen cabinet itself, in which the heating equipment will be located.

When operating a gas heating boiler of any type inside a kitchen, the air in such a room is burned in any case, which explains the requirements according to which it must be installed in kitchens with gas heating equipment. ventilation system.

In addition to the very fact of the presence of such a system in a kitchen room with a gas boiler, certain requirements are also imposed on the rules for performing its installation.

The hood, which will serve the gas boiler, cannot be connected to the kitchen exhaust duct; a separate duct must be installed for it.
The diameter of the ventilation duct to which the gas boiler exhaust will be connected must be calculated taking into account the performance of the heating equipment.
In the room in which the gas boiler and the exhaust ventilation system will be operated for its maintenance, a certain air exchange must be ensured, the specific value of which is stipulated by the requirements of SNiP 31-01 of 2003. According to the requirements of this regulatory document, when operating gas boilers with atmospheric burners, double air exchange is taken into account, and when using equipment with a closed combustion chamber, single air exchange.

Recommendations for choosing a gas boiler for installation in the kitchen

Before studying the requirements for the room for installing a gas boiler in the kitchen, you should decide on the choice of the equipment itself. So, the main parameters that you should pay attention to when choosing are:

power;
the number of contours in the structure;
combustion chamber type;
type of instalation;
type of heat exchanger used;
tank volume of built-in or external boiler;
the trade mark under which the equipment is produced.

In addition, when choosing heating boilers, one should take into account such parameters as fuel and electricity consumption, as well as the amount of water that such a device can heat up per unit of time.

First of all, you should study SNiP 31-02-2001 on gas supply to country houses. All legal requirements for the installed gas equipment are listed here. In addition, information on the requirements for the device of an autonomous heating system is also contained in the documents:

SNiP 41-01-2003 on ventilation, heating and air conditioning;
SNiP 2.04.01-85 on the internal water supply system;
SNiP 21-01-97 on fire safety;
SNiP 2.04.08-87 on the boiler room arrangement.

According to these requirements, in order to install a boiler in a house, it is necessary to first obtain technical conditions, which are the basis for organizing work on connecting household equipment to the central gas supply line. To obtain a technical specification, you need to contact the local gas service and submit an application indicating the estimated gas consumption for heating needs. In central Russia, gas heating consumes from 7 to 12 m 3 of gas per day.

The technical conditions are the official permission for the installation of gas equipment. Performing work without technical specifications is considered illegal and dangerous for home users.

When submitting an application for project approval, the following documents must be attached to it:

technical passport and instructions for using the installed boiler;
certificates of conformity;
confirmation of compliance of the gas unit with safety requirements.

Installation standards

The room in which the heating boiler is supposed to be mounted must comply with the standards specified in SNiP. For single-family and block houses, the installation rules are specified in SNiP 31-02-2001, the installation of gas heating units in apartments in apartment buildings is regulated by SNiP 2.08.01. Residential buildings.

It is also helpful to study the information provided in the following documents:

SNiP 2.04.08-87 "Gas supply";
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";
SNiP 42-101-2003 "General provisions for the design and construction of gas distribution systems from metal and polyethylene pipes."

Coordination and design

It is forbidden to carry out installation work until the corresponding project has been drawn up, agreed and approved

The homeowner submits an application to the local organization, whose function is to supply the main gas to the population. This is Gorgaz or Oblgaz. In the application, it is required to indicate what gas consumption is planned for heating, preparation of hot water, cooking, etc. In this case, they proceed from the heated area of the house, the need for hot water, etc. Calculations are performed according to the average indicators given in SNiP 31-02, clause 9.1.3.

Requirements for private houses

The current rules and regulations provide for the installation of a gas boiler unit in a room with sufficient ventilation, located:

on the 1st floor of a private house;
in the basement or basement;
in the annex;
in the attic;
in the kitchen - with power restrictions: only up to 35 kW (according to MDS 41.2-2000, installation of boilers up to 60 kW is allowed).

Note! There are two norms regarding the installation of a heating unit in the kitchen. Since the installed unit will be commissioned by the local gas service, at the design stage of the heating system, ask what rate this organization took as a basis.

Choosing which room to put the boiler in, you should take into account the power limitations:

150 kW and more - a separate room is suitable, regardless of the floor location;
151kW - 350kW - in the annex, on the first or ground floor, in the basement.

If, in addition to the boiler unit, it is planned to use a geyser, the capacity of the equipment is summed up. It is not allowed to install more than two heating units in one room.
