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

Types of water heaters

Almost all geysers have the same principle of operation and appearance. Differences between one or another model may lie in their technical characteristics and design performance. Currently, all modern speakers can differ in four main ways.

Throughput (or power) allows you to determine how much water the device heats up in a certain period of time. Today on the market you can find models with a capacity ranging from 6 to 18 liters. You should not buy more powerful speakers in the bathroom, since it is not advisable to use units with a capacity of 18 liters or more for domestic purposes. For a family of 4 people, a column with a capacity of about 12 liters is enough.
The gas burner affects the efficiency of the unit and ease of use. There are three types of burners used in geysers: constant or variable power, and modulating burners. A column in the bathroom with a constant power burner is able to independently regulate the flame, depending on how strong the pressure of water flows through the device. In columns with burners of variable power, it is necessary to regulate the flame manually, but after a single adjustment, the automation will independently maintain the selected temperature. The most modern - modulating burners allow you to get water at a stable temperature at the outlet, regardless of fluctuations and changes at the inlet. The price of modulating burners is slightly higher compared to variable and constant ones, and can range from 9 to 30 thousand rubles.
Ignition - can be manual (piezo ignition) or electric (battery powered). More expensive and modern models are equipped with electric ignition, powered by the electrical network of the apartment.
The number of functions - not only the price of the device depends on them, but also the reliability and safety, since most of the additional functions allow you to protect residents from gas leaks and regulate the pressure of water in the system and gas in the gas pipeline.

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.

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:

Autonomy - independence from hot water suppliers. And gas outages are extremely rare.
Creation of a comfortable level of heat in the premises with the possibility of its regulation.
In addition to heating the home, it is possible to use hot water.
Significant financial savings when paying for utility bills.
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.

Show or hide

Of course, we all want to make the bathroom as comfortable and aesthetic as possible, because it is not only a territory of hygiene, but also of relaxation. Large, not always attractive outwardly gas equipment usually does not fit into our ideas of a beautiful and comfortable bathroom, although now you can find speakers on sale that can become a bathroom decoration.

It would seem that the most obvious solution is to hide the geyser inside the wall, but all safety standards and requirements categorically prohibit this. Therefore, if you do not want to leave the instantaneous water heater in plain sight, you can hide it in a drywall niche or in a closet.

Boiler connection

Gas heating boilers installation and configuration

The main parameter when choosing a gas boiler is its power. It should be sufficient to ensure the normal functioning of the heating network, but at the same time not excessive. With excess power, the risk of cracking the heat exchanger is high. The so-called acid condensate can also form when the return temperature drops below the dew point of gases - 56 degrees. The high power unit quickly warms up the system and goes into standby mode until the temperature drops to certain parameters. After cooling, the boiler turns on again, but powerful heat exchangers have a high thermal inertia, so acid condensate may fall out before it is reheated.

The optimal power should be determined on the basis of thermal engineering calculations. The excess power must be within the allowable run-out. In a private house, you will have to do heat engineering calculations on your own or invite specialists. For apartment buildings, such data can be found at the technical inventory bureau.

Before installing the boiler, it is necessary not only to equip the room, but also to collect the necessary documentation:

Contract for the supply of gas - when installing a water heater, it will not be required.
Documents for the meter - it is forbidden to connect gas heating and water heating equipment without this device.
Documents from the BTI on making changes to the technical passport of a house or apartment. The new plan should take into account the location of the boiler room.
Technical passport for boiler equipment.

At this stage, you can submit an application to the gas service for the development of project documentation and specifications. You can install the device yourself until you receive the finished project, but on condition that the room fully complies with the standards and is approved by the regulatory authorities. Gas piping should only be done by employees of the gas services. Prior to commissioning, a suitability statement must be obtained from a gas service engineer.

If the boiler was connected to the gas main on its own, there is practically no chance of getting an engineer's opinion. Such work should be carried out only by gas specialists. You can independently mount the hydraulic and electrical piping of the boiler. As a rule, all the necessary requirements and instructions can be found in the instructions for the device.

Mounting Features

Knowing all the requirements for a gas column, you need to familiarize yourself with a number of rules that apply to the installation of equipment.

Installation and connection of the geyser must be carried out by licensed specialists.

Plumber specialist

The process of installing a geyser includes the following steps:

Initially, you need to install an asbestos pipe. To do this, you need to make an appropriate hole in the ceiling or wall. The length of the asbestos pipe should be approximately 1500 mm.
Then we proceed to the installation of the device itself. The geyser must have mounting holes, according to which markings are made on the wall

In this case, it is very important to use a level, otherwise it will not work exactly to install the device.
The equipment is fastened with special dowels with hooks. Under them, you need to drill holes in the wall, which will be identical in diameter.
After the geyser is installed, a corrugated pipe must be laid from the device to the chimney to remove combustion products.
Then you need to connect the water heater to the gas.
At the next stage, a connection to the water supply is made, while cold and hot water must be supplied to the geyser.
And the last thing to do is to install a filter, which can be magnetic or salt.

About installation rules

There are a number of requirements for the installation of gas equipment:

The vast majority of models need to be placed in a separate room. The exception is wall-mounted units - they can be mounted in non-residential rooms, for example, in the kitchen or in the bathroom, if their dimensions allow. Before installing the boiler, it is necessary to ensure the required ventilation in the boiler room.
The volume of premises for the installation of gas equipment with a closed chamber is not regulated, but the area must comply with the standards. In addition, the unit must have an outlet to the flue. It is unacceptable to bring it to the ventilation ducts.
Horizontally located parts of the gas duct cannot have a length of more than 3 meters and have more than three turns. The outlet of the gas duct must be raised above the roof level by at least a meter.
Wall models are mounted at a distance of 800 mm or more from the floor surface. No objects should be placed under the boiler, and a metal sheet must be laid on the floor. An expansion tank and an air valve must be installed.

Do not install gas equipment in the following types of premises:

In apartments of an apartment building without a main gas duct, these are most of the houses of the old building.
In rooms with false ceilings and capital mezzanines.

It is almost impossible to install a floor model in an apartment of a multi-storey building. After all, this will require a serious redevelopment with all the ensuing problems and costs. There are no restrictions on the installation of such equipment in a private house. Here it is better to make a separate boiler room, for example, in an extension. This room must meet the following standards:

Entrance doors - not already 80 cm.
Without fail, there must be a chimney that goes either to the roof or through the wall to the outside.
The height of the boiler room must be at least 2.2 m. The room is equipped with a ventilation system.

A double-circuit boiler with automation will require the allocation of a separate branch of electrical wiring. An additional 20 A automatic machine is installed on it. It is desirable to provide a backup power supply for automation that can support its normal operation at least during the day. To do this, you can purchase a diesel generator or a UPS - an uninterruptible power supply.

Serious requirements are placed on the gas duct. Its minimum diameter is 110 mm, regardless of the power of the installed equipment. The optimal diameter of the flue is calculated based on the power characteristics of the unit - the higher the power, the larger the diameter.

How to install a gas boiler in an apartment

The principle of operation of such units is quite simple - water from the heating system passes through the heat exchanger. As a result of the combustion of blue fuel, it is heated in a heat exchanger and then distributed through pipes and radiators.

get a number of permissions from the relevant services
purchase equipment
prepare the room
remake the heating system - cut it off from centralized communications
equip ventilation and provide for the installation of a chimney

A list of documents that need to be collected will be provided to you at the gas supply organization. Moreover, this is not an easy, troublesome and rather lengthy business.

Installation of a gas boiler in an apartment is carried out by specialized organizations subject to certain rules:

The area of the room in which the equipment will be located must be at least 4 square meters.
Good natural lighting - a window of 0.3 square meters relies on 10 square meters of area. m. A prerequisite is the presence of a window.
The width of the front door is at least 80 centimeters.
The height of the room is at least 2.5 meters.
The presence of a pipeline with cold water.
Output from the ground loop.
Chimney installation.
The presence of a ventilation duct.
Smooth and plastered walls.

If the room is equipped in compliance with these simple rules, and there are relevant documents available, then you can proceed with the installation of gas equipment. It is strictly forbidden to carry out the installation on your own, since only employees of a specialized organization should do this.

Features of repair and design of a kitchen with a geyser

It is necessary to plan the design and repair of a kitchen with a geyser 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.

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.
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.
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.
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 finished with ceramic tiles (see photo).

Small kitchen with gas water heater and ceramic tiled walls

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.
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.
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.
And the last piece of advice - “in any incomprehensible situation”, consult the gas service and act in accordance with the instructions of regulatory documents.

Tips for installing speakers in the bathroom

Since the new requirements do not contain clear instructions and specific prohibitions regarding the installation of gas equipment, some people manage to obtain the necessary permission from the gas services.

For example, officially gas heating and heating appliances in the bathroom can only be installed in technical premises - change houses, storage rooms. You can install a column or a gas boiler in the bathroom by issuing official permission during the development of a private house project. In this case, the installation of water heating and heating equipment is carried out in the place where it is allowed, and after obtaining permission, plumbing is installed and fenced off with a plasterboard partition.

It should be noted that when selling such a house, problems may arise, since for the examination by specialists of the relevant service, the homeowner will have to remove the walls.

Mounting Features

Installation, adjustment of gas boilers

If you choose from all types of gas devices, then the most acceptable option for an apartment is a double-circuit wall-mounted boiler. With it, you can provide heat in the room and hot water for domestic needs. And placing on the wall will significantly save usable space.

If in private houses it is possible to choose even a separate room for a heating unit, then for a city apartment the most acceptable option is a kitchen, where there is already a gas stove, cold water supply and, as a rule, reliable ventilation. Therefore, installing gas heating in the kitchen is the best solution for a small area of a city apartment.

Modern products of the double-circuit type incorporate a circulation pump, the operation of which requires the constant presence of electric current. In the event of an emergency situation with the provision of electricity in country houses, a backup power source is installed in the form of a power plant.

Important! This cannot be allowed in an apartment, so for emergency connection you can use an uninterruptible power supply, like for a computer, only more powerful. It will last for several hours of work until the accident on the electrical networks is eliminated.

For normal operation of the gas boiler, an expansion tank is also required, in which there must always be water for the heating system. Water or another type of coolant expands when heated, and its excess enters this container, and when cooled, it goes back into the system.That is, the principle of operation of the expansion tank is the same as for the car cooling system.

The installation of gas boilers is strictly prohibited in the following cases:

installation of devices near combustible objects
in the hallway and bathroom due to high humidity and reduced fresh air supply
in dormitories
in the basement and on the balcony
in the basement, which is located below ground level
in rooms not equipped with air vents

Regarding the basement - it is allowed to install gas equipment if there is a special permit from the regulatory authorities.

How is the repair of a bathtub with a geyser

From the very beginning, you need to think about the fact that if the column is old, it is best to replace it with a new, more modern, powerful and safe one, so that in the future you do not have to repair the gas appliance. Further, the owners must understand that it is far from always possible to move and transfer a geyser from one wall to another, which is due to the restrictions established in SNiPs for the safe use of gas equipment. However, despite such seemingly harsh conditions, if you approach the issue of repair correctly, as a result, the bathroom will become beautiful, comfortable and practical.

Bathroom renovation steps:

Calling a designer to determine the type of repair, style direction, use of certain finishing materials
Drawing up a project and budget
Procurement of necessary building and finishing materials and mixtures
Dismantling of old plumbing fixtures, turning off and removing the geyser, leveling walls, ceiling and floor
Replacement of water and sewer pipes
Laying flooring, laying out walls with tiles, making plasterboard, suspended or slatted ceilings
Installation and connection of a new geyser (or old, if it is serviceable and operational).

It should be understood that repairing a bathroom with a geyser is not an easy job, which should only be trusted by qualified craftsmen. Specialists of the MasterSanuzlov organization will be able to quickly and comprehensively complete the task, taking on all the work. Everything is done on a turnkey basis, delivered within a strictly specified time frame, and our craftsmen always clean up all the construction debris.

Is it possible to put a geyser in a bathroom in a private house

According to SP clause 7.6:

"The engineering systems of the house must be designed and installed taking into account the safety requirements contained in the relevant regulatory documents and the instructions of the equipment manufacturers' instructions."

Based on this paragraph, the rules for installing a geyser in a private house do not differ from the requirements in force in an apartment building.

Accordingly, it will be decisive to determine the premises suitable for the installation of a gas water heater, based on the description set out in the SP. Current regulations will not allow (at least legally) gas equipment to be placed in the bathroom of a single-family house.

Another important point. Most specialists producing project documentation still take into account the norms that were in force until 2013. When making decisions, they rely on regulatory documents in which the installation of a gas water heater in the bathroom is clearly prohibited.

What are boilers for individual heating

There are many types of heating units that can be installed in apartments:

Single boiler. Such a device is only suitable for space heating. If you also need to heat water for family use, then this unit will not work. Of course, it can be installed, but in addition you will also have to purchase a boiler for heating water, and this, in turn, is fraught with unnecessary costs.
Double boiler. Such a heating unit is the most popular, because thanks to it you can also use hot water around the clock. The dimensions of such boilers are quite compact, so they can be installed even in a small kitchen.

If you choose from these two options, then, of course, the second option will be the best. An individual boiler in the apartments is installed on the walls, so the usable area in the kitchen is saved. Many modern high-rise buildings do not have chimneys. But this is not a reason to give up your dream - installing a gas unit. After all, there is another great way, thanks to which combustion products are removed to the outside. This is the installation of a coaxial pipe, or it is also called a coaxial chimney.

Gas boilers can have an open combustion chamber or a closed one. For an open chamber, a chimney is a prerequisite for installing gas heating in apartments. If an individual heating unit has a closed combustion chamber, then a coaxial pipe can be installed to output combustion products, which simultaneously supplies oxygen to the combustion chamber and removes unnecessary substances through another hole.

Rice. 2 Gas heating in the apartment

What are good boilers with a closed combustion chamber:

Such units for individual heating are safer to use for others, as they prevent combustion products from entering the room.
They are easy to operate and have a much longer service life.

Also, many gas heating units only work when there is electricity. Therefore, if you live in an area where electricity often disappears, then you need to get an additional power source. After all, how do you not want to freeze in severe frosts.

Use of liquefied gas

"Troubles" with project documentation are not required in the case of using not natural, but liquefied "cylinder" gas. However, the column in this case must have an appropriate design - burners for natural and liquefied gas have different diameters of injector nozzles. Although such equipment is produced by many manufacturers, it is quite rare and demanding on gas quality.

In any case, the wall at the installation site of the column must be strong and non-combustible - if it is made of drywall, then a "mortgage" for fixing the heater, made of wood or metal, must be mounted in it in advance.
