Is it possible to install a gas boiler in the bathroom: rules and regulations

Installation: recommendations and diagrams, the main stages of the installation of the chimney

The installation of the chimney is divided into several stages - this is the preparatory work, the installation itself, then the connection, start-up and, if necessary, debugging of the entire system.

General requirements

When combining several heat generating installations, a separate chimney is created for each of them.In exceptional cases, a tie-in to a common chimney is allowed, but at the same time, a difference in height of at least one meter must be observed.

First, the parameters of the chimney are designed and calculated, which are based on the recommendations of the manufacturers of gas boilers.

When summarizing the calculated result, the inner section of the pipe cannot be less than the diameter of the boiler outlet pipe. And according to the check according to NPB-98 (fire safety standards), the initial speed of the natural gas flow should be 6-10 m / s. And besides, the cross section of such a channel must correspond to the overall performance of the unit (8 cm2 per 1 kW of power).

Installation steps

Chimneys for gas boilers are mounted outside (add-on system) and inside the building. The simplest is the installation of the outer pipe.

Installation of an external chimney

Installing a chimney at a wall-mounted boiler is done as follows:

1. A hole is cut in the wall. Then a piece of pipe is inserted into it.
2. A vertical riser is assembled.
3. The joints are sealed with a refractory mixture.
4. Fixed with wall brackets.
5. An umbrella is attached to the top to protect it from rain.
6. An anti-corrosion coating is applied if the pipe is made of metal.

Proper installation of the chimney guarantees its impermeability, good draft, and prevents soot from accumulating. Installation performed by specialists will significantly reduce the cost of maintaining this system.

In the case of arranging an opening for a pipe in the roof of a house, special boxes with aprons are used. In this case, the design as a whole is influenced by such factors as:

• The material from which the pipe is made.
• Exterior design of the chimney.
• Type of roofing.

The main factor influencing the choice of design is the temperature of the gas that passes through the pipe. At the same time, according to the standards, the distance between the chimney pipe and combustible materials must be at least 150 mm. The most advanced is the assembly system by segments, where all elements are assembled by cold forming.

Connecting a ceramic chimney

Ceramic chimneys themselves are almost eternal, but since this is a rather fragile material, you need to clearly imagine how the connection (docking) of the metal part of the chimney and the ceramic one is correctly performed.

Docking can only be done in two ways:

By smoke - a metal pipe is inserted into a ceramic

It is important to remember here that the outer diameter of the metal pipe should be smaller than that of the ceramic one. Since the thermal expansion of the metal is much greater than that of ceramics, otherwise the steel pipe, when heated, will simply break the ceramic one.

For condensate - a metal pipe is put on a ceramic one.

For both methods, specialists use special adapters, which, on the one hand, are equipped with a gasket for contact with a metal pipe, and on the other, which contacts directly with the chimney, are wrapped with a ceramic cord.

Docking should be carried out through a single-wall pipe - it has a higher heat transfer coefficient. This means that the smoke will have time to cool down a little before it reaches the adapter, which ultimately extends the life of all materials.

VDPO shows great requirements for chimneys for gas boilers, because of this, it must be installed by specialized teams. Since competent installation guarantees not only long-term operation of the device, but also makes living conditions in a private house safe.

Types of water heating equipment for the bathroom

Today, the range of devices for heating water is very wide and varied. The choice of equipment suitable for household needs depends on how many liters of water per day each family member needs. In addition, when purchasing a water heater, it is necessary to take into account such indicators:

• Energy source
• The location where the unit will be installed. For small apartments, it is advisable to choose compact water heaters.
• Safety.
• Source of consumed energy.
• The amount of gas or electricity consumed.

If a number of problems can arise with the installation of gas-powered units in the bathroom, then the installation of water heating equipment in such parts of the house is allowed. That is why most apartment owners use storage tanks to heat water, which, moreover, provide heating for the bathroom.

Currently, the most common water heaters are:

• Storage units for heating water.
• Flow type water heaters.
• Single-circuit and double-circuit boilers.
• Thermostatic mixer-water heater.

Boiler installation approval

You need to go through several instances to get approval for the installation of a gas-fired boiler.Independently, without approvals, the installation process will be illegal and unsafe, and not only for the owner of the home, but also for the rest of the residents of the house, if the boiler is installed in a high-rise building.

1. Specifications

To connect a private house or apartment to the gas supply, you will have to obtain technical conditions from the gas supply organization that allow this procedure. For this, an application is written to the controlling organization. It must indicate the approximate demand for the volume of gas per hour. The application process takes seven to fourteen days. Upon successful completion of this event, a document will be issued - the technical conditions for the installation of gas-fired equipment. This is the permit for preparatory construction and installation work.

2. Project

With the technical specifications in hand, you can proceed to the second step - the development of project documentation. The gas supply project includes schemes for laying a gas supply pipe from the boiler installation site to the central gas pipeline.

The project will also indicate sections of the gas pipeline crossing the section

If the dwelling is located in the private sector, and the pipeline must cross the land, then a diagram of the gas pipe is also drawn up on the site, which indicates the place of its entry into the wall of the house. The project is developed by engineers licensed for such activities, based on the provisions of the GOS.

3. Coordination with the gas supply organization

The finished project is submitted for approval to the organization that controls the gas supply in the applicant's area of ​​residence. Project approval takes from seven to one hundred days - it depends on the volume and complexity of the document. The following materials regarding the heating device are attached to the project:

• examination of the compliance of the boiler with all the requirements that are necessary to ensure normal operation and safety;
• technical passport of the device;
• certificates of compliance with technical and sanitary requirements;
• operating instructions.

All documents specified in the list are drawn up by the manufacturer and must accompany any product of this type without fail.

They are transferred by the seller to the buyer when purchasing the device - special attention should be paid to this

If the project was rejected for the first time, the applicant is issued a document that indicates the reasons for the rejection and a list with a detailed listing of all project problems that need to be corrected.

If the project is approved, it is certified by the signature and seal of the responsible person. This document is the final approval for the installation of the heater.

Some nuances of installing flow-through gas heaters in the toilet and bathroom

For owners of private cottages, there is another way to obtain official permission to install a boiler or gas heater in the bathroom. First, official documentation is drawn up during the development of the project.

Install gas equipment in the part of the dwelling where it is allowed. Then, plumbing is installed next to the device, for example, a bath and equipped around a plasterboard partition. Such an impromptu redevelopment, of course, cannot be called ideal. Subsequently, if the owner wants to sell the house, a number of problems may arise.Specialists from the Bureau of Technical Inventory will be able to conduct an examination only after dismantling the walls.

Officially, the installation of a gas boiler is provided only for technical premises - storage rooms, change houses. If such rooms meet the requirements adopted for them, the installation of gas-fired water heaters is permitted.

Appearance of a floor gas boiler

High levels of humidity in the bathroom, temperature fluctuations often lead to breakdowns of gas heaters. Before deciding on installation, it is worth considering all the advantages and disadvantages, assessing the financial feasibility of installing such equipment. Obtaining official permission from the relevant authorities is not easy, it can be done with some legal tricks.

What you need to know when installing a gas boiler in the bathroom?

When looking for a convenient place to install a gas boiler, the owners often stop at the bathroom or toilet. But to what extent is such placement allowed by the rules of SNiP and fire safety standards? Before you install a gas boiler in the bathroom, you should understand this issue in detail.

…

You are unlikely to find a clear answer to the question of whether it is possible to install a gas unit in a bathroom in the documentation. The norms of SNiP 1987 prohibit the placement of such equipment in the bathroom. However, later - since 2003, the above SNiP was declared invalid and SNiP 42-01-2002 "Gas distribution systems" was put into effect instead. But it does not clearly indicate whether it is possible to install a gas boiler in the bathroom. You can get an affirmative answer only by contacting your gas supply company.

Important! Installation in a bathroom or toilet is subject to only a device with a closed combustion chamber mounted type. As practice shows, most gas workers prohibit the installation of gas equipment in the bathroom. The main reasons for rejection are:

The main reasons for rejection are:

As practice shows, most gas workers prohibit the installation of gas equipment in the bathroom. The main reasons for rejection are:

• requirements of old standards;
• insufficient room size;
• high humidity in the bathroom, which leads to a quick failure of the equipment;
• interruption of thrust due to the mixing of moisture with combustion products.

It is easier for those who already have a gas boiler in the bathroom or toilet. Then they change the old unit for a new one without long paperwork.

However, some owners go for tricks, and in order to get permission from the gas service, they pass off the future bathroom as a furnace. And after installing the unit, they also place a shower and a sink there. But such a violation is fraught with negative consequences in the form of penalties and disconnection from the gas pipeline. The fact is that gas workers are required to periodically check the gas equipment located in the house, so in a year or two the fraud will still open and you will have to pay dearly for it.

…

If, despite the refusal, you are ready to continue to seek permission to install the unit in the bathroom, then you can go the following way:

1. The head of the gas service needs to make a request to connect a heating device in the bathroom. In this case, a list of regulatory documents that allow this should be attached.
2. If you are refused, you can file a lawsuit in court, where there is always the opportunity to win the case.

Pros and cons of installing a gas boiler in the bathroom

Many are attracted by the installation of a gas device in the bathroom for the following reasons:

• compact location;
• the unit is not "striking" and does not interfere with the movement;
• hot water is immediately supplied to the main points of water intake - the sink and shower.

…

This location also has disadvantages:

• high humidity adversely affects the metal parts of the device;
• bathrooms usually have small dimensions, so even a compact mounted unit will take up quite a lot of space in it;
• it is highly likely that in order to fulfill all safety requirements, the bathroom will have to be re-equipped.

Think carefully about whether such placement of a gas boiler is suitable in your case. Perhaps the best installation option would be a kitchen or hallway.

What are the requirements for a bathroom?

It is important to understand that not every bathroom is suitable for installing a gas boiler. For example, standard bathrooms in ordinary Khrushchev houses or 9-story buildings built in the 70s and 80s are too small and do not have sufficient ventilation. In order for it to make sense to at least consider the possibility of installing a gas boiler in the bathroom, it must meet certain requirements:

In order for it to make sense to at least consider the possibility of installing a gas boiler in the bathroom, it must meet certain requirements:

• total area of ​​at least 7.5 m²;
• the presence of a working ventilation system;
• there must be a window with an area of ​​at least 0.25 m²;
• ceiling height not less than 2 m;
• when the door is closed, there should be a gap of 1-2 cm between it and the floor;
• nothing should be located in front of the unit at a distance of 1 m;
• bathroom walls must be made of non-combustible materials.

Thus, from the above requirements it can be seen that the owners of apartments in multi-storey buildings are practically deprived of the possibility of installing a gas boiler in the bathroom. Owners of private houses have more chances, as they can initially build a bathroom that meets all the above standards.

Regulatory framework governing the scope

Improper use of gas equipment often leads to negative consequences. Therefore, the state has regulated this area to the smallest detail.

And, in view of this feature, one, even a voluminous document, will not be able to contain all the necessary information.

All the necessary rules for the installation of gas boilers are set out in the governing profile documents. But the problem is that there are a lot of them and it will take a lot of time to get to know them. Therefore, in most cases, you have to rely on specialists

As a result, there are indeed many kinds of instructions. For example, certain related issues regulate:

• SP-401.1325800.2018, which sets out the design rules for all kinds of gas consumption systems in residential buildings;
• SP 62.13330.2011, which indicates what the gas pressure should be, how to properly lay pipes to the boiler, etc.;
• GOSTs with numbers R 52318-2005; R 58121.2-2018; 3262-75. Where it is indicated which pipes and fittings can and should be used when installing a gas boiler. In addition, steel and other types of gas pipelines are described. And also their characteristics are indicated;
• GOST 27751-2014; SP 20.13330. These documents set out the requirements for the load on external and internal gas pipelines used to install boilers;
• SP 402.1325800.2018, which sets out the rules for connecting boilers to the power grid;
• SP 28.13330, and in some cases GOST 9.602-2016, which describes methods for combating corrosion;
• SNiP 21-01-97. This document outlines the safety measures that should be observed during the operation of buildings, including those heated by gas boilers. As well as the division of building materials into combustible, non-combustible. And such information is important when equipping the room in which the boiler will be placed.

In addition, you should familiarize yourself with the rules set forth in SP 60.13330.2016 (this document is an updated version of the well-known SNiP 41-01-2003). After all, it is in this by-law that it is indicated that individual heating sources and what they should be can be used to heat housing.

And this is not all that you need to know to ensure the correct placement of the boiler and further safe operation.

It is imperative to comply with the current requirements when installing boilers. Since otherwise, the specified unit will simply not be allowed for operation. BUT for unauthorized connection severe sanctions are provided in the form of large fines (from 10 thousand rubles). This is stated in Art. 7.19 of the Code of Administrative Offenses, as well as in Art. 215.3 of the Criminal Code

And if, for example, the question arose of why you need to know the safety measures or loads on pipes during construction. Then it should be remembered that the installed boiler will be allowed for operation. And, when the established rules set out in the relevant document are not followed, the identified shortcomings will have to be eliminated.

In the case when the purchased gas boiler is being installed in your own wooden house and the requirements for the size of the foundation are not met, which at any point must exceed the dimensions of the boiler by at least 30 cm. Then, instead of enjoying comfort, you will have to dismantle the structure and perform new work.

Benefits of gas heating

Everyone knows that residents of apartment buildings in the city pay much more for heating their homes than people living in country houses. What is it connected with?

First of all, with the fact that the prices for heating and hot water are too high, and sometimes simply unreasonably high. At the same time, the temperature in the apartment often does not correspond to the norm, so there can be no pleasure from such a stay.

To solve the problem, some citizens install an autonomous heating system with a gas boiler, the advantages of which are obvious:

1. Autonomy - independence from hot water suppliers. And gas outages are extremely rare.
2. Creation of a comfortable level of heat in the premises with the possibility of its regulation.
3. In addition to heating the home, it is possible to use hot water.
4. Significant financial savings when paying for utility bills.
5. Creating coziness and comfort, regardless of the beginning of the heating season - at any time, in cold weather, in autumn and spring, you can independently turn on the heating of the apartment.

Where is it possible to install a gas boiler

The installation of a gas boiler in the house must meet certain requirements. Moreover, they are mandatory, regardless of whether it works for hot water supply or not.

one.The boiler should be mounted in a separate room with an area of ​​at least 4 m2, and the ceilings must be at least 2.5 meters. The rules also indicate the volumetric size of the room - at least 4 m3.

2. In the room with the boiler, an opening window or window is required. The door must be at least 80 cm wide.

3. Interior decoration made of combustible materials is prohibited. Suspended ceiling technology is prohibited.

4. It is necessary to organize a constant flow of fresh air into the room. The opening for the inflow must be constantly open, and its cross section must be from 8 cm2 for every 1 kW of the declared power of the heating equipment.

Pay attention! In order to install a gas boiler in a house with a capacity of 30 kW, you need 8 m3 of free space. Further, according to the increase in power - for 31-60 kW, 13.5 8 m3 should be provided, for 61-200 kW, 15 m3 of free volume is required .. In addition, the following standards must also be provided for the operation of heating equipment of any kind:

In addition, for the operation of heating equipment of any kind, the following standards must also be provided:

• The exhaust pipe must be led into a separate flue. Connection to ventilation ducts is prohibited.
• The horizontal flue must be no longer than 3 meters indoors. It is allowed to organize no more than three corners and turns.
• The flue exits vertically from the house. The height is 1 meter more than the highest point of the pediment.
• The chimney must be made of bases highly resistant to chemical and thermal influences. The use of a layered base (asbestos-cement pipes) is allowed only at a distance of 5 meters from the edge of the outlet pipe.

When a gas boiler is connected in the kitchen, the requirements are also added:

• The hanging height of the boiler must be organized according to the following scheme - the lower branch pipe must not be lower than the upper part of the spout at the sink. However, in any case, the height from the floor should not be less than 80 cm.
• There must be free space under the hung boiler.
• The floor under the gas equipment must be covered with a metal sheet (size 1000 x 1000 mm). The requirements of gas workers and the fire service do not allow asbestos-cement coatings, tk. it wears off over time. On the other hand, the requirements of the SES do not allow the presence of elements in the house that contain asbestos.
• Premises with gas equipment should not have any cavities in which explosive mixtures or combustion products can accumulate.

As you can see, the rules strictly regulate the installation process. However, there is an excuse for this, because. gas is dangerous. That is why you can forget about installing a gas boiler if:

1. You are the owner of an apartment in a multi-storey building (Khrushchev) in which there is no main flue.

2. The kitchen has false ceilings or solid wood furniture.

3. In the absence of privatization for an apartment. Only the installation of a water heater is possible. The thing is that redevelopment will be required, which only the owners are allowed to perform.

The remaining cases allow the installation of hot water boilers in apartments. Wall heating is allowed, but with floor heating everything will be with big problems.

A private house will be easier in this regard. In such a case, there are no clear requirements for arranging a boiler room in the house itself. You can build an extension that does not cause unnecessary questions.

In private housing, in general, the best option would be to install a wall-mounted boiler. It does not require the arrangement of cunning protective structures.

Features of repair and design of a kitchen with a geyser

To plan gas kitchen design and renovation the column is necessary with an eye to fire safety rules, ventilation and ergonomics requirements. Here are some important tips to help you set up your workspace in the best possible way.

1. If you are equipping a kitchen from scratch, then it is advisable to think about the location of the gas column, layout and interior design even before repairing and buying furniture. Then you will have more room for maneuver and fewer problems. For example, you can move the column, change it to a more modern or suitable model for the future environment, improve ventilation and chimney along the way, adjust the color scheme of the interior to match the column, etc.
2. It is advisable to purchase a kitchen set to order, regardless of whether you plan to build a water heater in a cabinet or not. This will allow you to compose the headset without errors and use every centimeter to your advantage.
3. Is it possible to install a stretch ceiling in a kitchen with a geyser? It is possible if the height of the room with the installed canvas will be at least 2.25 m, and there will be a distance of at least 8 cm from the chimney opening to the ceiling. thermal insulation layer. So the ceiling will not be damaged by heat (from the products of combustion leaving the chimney) and will not itself become an obstacle to traction. If necessary, the chimney opening can be slightly lowered.
4. Walls in a kitchen with a gas water heater should not be finished with wallpaper or plastic panels (at least near the water heater), as these materials can deteriorate / melt under the influence of heat. Ideally, the walls should simply be plastered, painted or tiled (see photo).

Small-sized kitchen with a gas water heater and walls lined with ceramic tiles

1. In a kitchen with a geyser, a constant supply of fresh air (50-90 cubic meters per hour) is required. This is necessary both for your safety and for the stability of the combustion of the unit. Therefore, when installing plastic windows, choose those that have the function of micro-ventilation, that is, special fittings that allow you to open windows with micro-slits from 3 to 7 mm. Both in winter and in summer, the windows of the kitchen with a geyser should be opened in this mode. If wooden windows are planned or already installed in the kitchen, then due to their natural micro-slits, the issue of passive ventilation will be resolved by itself. The main thing is not to overdo it with waterproofing, seals and window insulation.
2. Supply ventilation valves embedded in the wall, for example, Kiv-125 or KPV-125, will help to ensure the flow of air even more efficiently. It is advisable to take care of their installation before repair, so as not to spoil the finish.
3. In a kitchen with a geyser, both the supply and exhaust systems must work in a balanced way. Therefore, it is necessary to invite professional ventilation specialists to check the chimney and ventilation duct. If necessary, they must be put in order.And, of course, when arranging the kitchen, do not make the grossest and, unfortunately, common mistake - do not close the ventilation duct with plasterboard boxes, wallpaper, or furniture.
4. And the last piece of advice - “in any incomprehensible situation”, consult the gas service and act in accordance with the instructions of regulatory documents.

Choice of gas device

A geyser is a device that is not purchased for a day, and not for a month. Such a mechanism should serve you for years and create complaints.

To make your choice the most practical and efficient, when choosing a geyser, pay attention to the following parameters:

Geyser performance

This most important criterion is responsible for the volume of water that the device is able to heat in one unit of time. As we mentioned, speakers are divided into products of low, medium and high power.

Your choice depends on the following nuances:

• your personal needs;
• the number of people living in the house;

• number of intake points: the mechanism can heat water not only for the bathroom, but also for the kitchen.

  Gas station can heat water for the kitchen and bathroom

If each of the aspects is higher, you need to give preference to a more powerful product.

Ignition type

The column can be ignited by matches (lighter), a piezo that provides a spark, or automatic equipment.

Such a mechanism is both safer and more convenient.

Burner type

This nuance is very important, because some models require your intervention, which is not very practical. For example, a constant power burner requires manual adjustment.And the modulating power burner automatically adjusts itself to the frequently changing water pressure, guaranteeing a stable temperature level.

Removal of combustion products

At this point, you need to choose a turbocharged or chimney mechanism. In the first case, all waste is removed through the pipe just to the street, in the second case - into the chimney.

There are two options for waste output: turbocharged or chimney mechanism

Safety

Each device has several levels of security. Experts recommend purchasing a product with three degrees of protection for the bathroom. Such mechanisms have the following protective functions:

ionization sensor: it blocks itself if the flame goes out, the thrust level drops or disappears altogether;
overheating sensor: pay attention to the presence of a hydraulic safety valve that will protect the mechanism from overheating;
combustion sensor: the system will automatically shut off the gas supply if the flame goes out, the ionization sensor did not work;
draft sensor: protects the column from turning on or off in the absence of draft;
water temperature sensors.

Each of the sensors is optional, but agree that you will be much calmer with them.

We have presented you with the most important five criteria that will determine the quality and durability of a new bathroom appliance. However, do not forget about the manufacturer, which is also important when choosing a column.

Geyser firm Valliant

Among the world manufacturers of such equipment, the following names are most trusted:

• Ariston;
• Termaxi;
• Vaillant;
• Beretta.

Geysers produced by the presented manufacturers are considered the golden mean in the technology market.Such companies offer a wide range of devices at different prices, and most importantly, high quality.

Requirements for a room for installing a gas boiler

Comprehensive information on the proper preparation of the premises is contained in one of the above documents. In particular, there are regulations on the dimensions of the boiler room, the arrangement of the front door, the height of the ceiling and other important parameters (see key requirements below).

It is immediately worth noting that if the maximum thermal power of a gas boiler is more than 30 kW, then a separate room must be allocated for its installation. Models with a lower capacity and with an appropriate location for the chimney outlet can be installed, for example, in a kitchen room. It is strictly forbidden to install a gas boiler in the bathroom.

You can not install it in the bathroom, as well as in rooms that are considered residential for their intended purpose. As an alternative, it is allowed to equip the boiler room in a separate building. At the same time, their own norms are taken into account, about which there is information below.

A boiler room in a private house can be equipped at the basement level, in the attic (not recommended) or simply in a room specially equipped for these tasks.

In accordance with the rules for installing a gas boiler in a private house, it must be equipped with the following criteria:

• The area is not less than 4 m2.
• One room is calculated for no more than two units of heating equipment.
• Free volume is taken from 15 m3. For models with low productivity (up to 30 kW), this figure can be reduced by 2 m2.
• From the floor to the ceiling should be 2.2 m (not less).
• The boiler is installed so that the distance from it to the front door is at least 1 m; it is recommended to equip the unit near the wall, which is located opposite the doorway.
• On the front side of the boiler, at least 1.3 m of free distance must be left for setting up, diagnosing and repairing the unit.
• The width of the front door is taken in the region of 0.8 m; it is desirable that it opens outwards.
• The room is provided with a window with a window opening outward for emergency ventilation of the room; its area must be at least 0.5 m2;
• Surface finishing should not be made from materials prone to overheating or ignition.
• A separate power line is introduced into the boiler room to connect lighting, a pump and a boiler (if it is volatile) with its own circuit breaker and, if possible, with an RCD.

Particular attention should be paid to the arrangement of the floor. It must have a solid base in the form of a rough screed with reinforcement, as well as a top coat of absolutely non-combustible materials (ceramics, stone, concrete)

To make it easier to set the boiler, the floors are made strictly according to the level.

On a curved surface, the installation of the boiler may be difficult or impossible due to insufficient reach of the adjustable legs. It is forbidden to place third-party objects under them to level the unit. If the boiler is installed unevenly, it may not work correctly, with increased noise and vibrations.

To fill the water heating system and feed it during operation, it is necessary to enter a cold water pipeline into the boiler room. To drain the system for the period of maintenance or repair of equipment, a sewer point is equipped in the room.

There are special requirements for the chimney and ensuring air exchange in the boiler room of a private house, therefore this issue is considered in a separate subparagraph below.

If the room for the installation of a gas boiler is equipped in a building separate from a private house, then the following requirements are imposed on it:

• your foundation;
• concrete base;
• the presence of forced ventilation;
• doors must open outward;
• the dimensions of the boiler room are calculated according to the above standards;
• it is allowed to install no more than two gas boilers in the same boiler room;
• the presence of a properly equipped chimney;
• it must be freely accessible for cleaning and other operations;
• for supplying piece lighting and heating equipment, a separate input with an automatic machine of the appropriate power is provided;
• the water supply must be organized so that the mains do not freeze during the cold season.

Mini-boiler room mounted near the house.

The floors, walls and ceilings of a separately equipped boiler room must also be made and finished with materials that correspond to the class of non-combustible and heat-resistant.
