Residents of the private sector value autonomy. The main thing is to ensure a comfortable life, which is impossible without hot water. Installing a geyser will solve problems with hot water supply (hot water supply). But how to solve the problem of connecting it? What do you need to do the work yourself? Let's figure out what permits need to be obtained and what documents to draw up in order to legalize the installation of equipment.
Which gas water heater is better to buy?
The choice of heater depends on the number of water points that the boiler will serve and the required volume of hot water, taking into account the needs of the family. But there are a number of technical characteristics that you should also pay attention to when purchasing.
The power of the geyser determines how much hot water and to how many points it can supply:
- Up to 20 kW – one consumer, 11 l/min;
- From 21 to 25 kW – for two points, up to 15 l/min;
- From 26 to 31 kW – for three points, more than 16 l/min.
Combustion chamber type. Inexpensive models use open-type cameras. In them, the combustion of the flame is supported by air coming directly from the room, and combustion products are discharged through the chimney.
When choosing such equipment, you will need to organize fresh ventilation (or simply keep the kitchen window slightly open).
Closed-chamber water heaters use air from outside to support the flame. Soot and smoke are discharged there. You can install such speakers even in closed rooms without windows.
The geyser should be equipped to the maximum with all available security systems. At a minimum, it will need protection against overheating and automatic gas shutoff in the event of a lack of water or an extinguished burner.
You can learn about other parameters for choosing gas pumps from our article. Now let’s look at the best models of water heating equipment that have recently entered the market.

Legal basis for installing gas equipment
Considering the special importance of gas supply for the population as an energy source, Federal Law No. 69-FZ was adopted in 1999, which is called: “On gas supply in the Russian Federation.”
The law regulates the entire complex of relationships that arise between the gas production industry, the gas transportation system and gas consumers. However, there is no direct answer to the question of how the owner of the premises should act and what documents will need to be submitted in order to obtain permission to install gas equipment.
The best flow-through geysers with an open chamber
Water heaters with an open combustion chamber are installed in rooms with a chimney and good ventilation.
As a rule, these are the simplest speakers without automatic controls that do not need to be connected to electricity. However, among them there are also more advanced devices.

Advantages:
- Low noise level;
- The design of the collector eliminates carbon monoxide leakage;
- Stylish design;
- Fast heating;
- Stable maintenance of the desired temperature.
Flaws:
- Uneven heating.
The column can be installed in a spacious bathroom with a window or in the kitchen, since it is designed for one water intake point. This model is suitable for singles and couples who live separately from children.
Main varieties
Gas instantaneous water heaters (columns) are small in size, making it possible to install them in small rooms (in the bathroom or kitchen). The purpose of the device is to quickly heat water passing through the heating element in the column. An important requirement for flow-through technology for stable operation is a gas pressure of 12 mbar. There are two types of gas flow heaters: with an open combustion chamber and a closed one. Both types have their advantages and disadvantages.
This is useful: what types of water heaters are there and how to repair them.
In a column with an open combustion chamber (atmospheric), when burning the burner, air coming from the room in which the unit is installed is used. The entry of oxygen and the exit of flue gases is carried out through the natural movement of air masses. Atmospheric instantaneous gas water heaters are equipped with a simple device without complex automation. They are considered reliable and durable in use.
In this video we will learn how to repair a gas heater:
A turbocharged column is better because during combustion it burns oxygen from the street (they have a coaxial chimney). These models have several advantages:
- They use modulation types of burners with low gas consumption.
- They can operate at low water pressure from 0.3 MPa.
Disadvantages include energy dependence and high cost. To ensure normal operation of the structure, the installation of a stabilizer and a UPS is required. If they are sufficiently equipped with automation, they may fail, as there are frequent power surges in the network.
Advantages and disadvantages
There are a large number of different types of water heating units. Everyone chooses according to their taste and capabilities.
Main advantages:
- produces an unlimited volume of water compared to storage heaters;
- compactness allows you to install it in a small room;
- breakdowns of additional functions can be easily and inexpensively fixed;
- maintenance is not labor-intensive (disassembling and cleaning will not be difficult);
- using sensors, possible gas leaks are eliminated;
- saving on fuel, since natural gas is much cheaper than electricity.
Different types of water heaters according to their technical design must be selected taking into account the conditions in which they will be installed. The characteristics of the room should be taken into account. To do this you need:
- the presence of a chimney to remove combustion products;
- take into account the volume of water for the required consumption, as well as the number of intake points;
- is there free space for convenient use of the speaker;
- matching the design of the equipment and the room.
It is better to invite a specialist to install the water heater. He will determine the draft and supply gas and water pipes. In addition to the positive aspects, there are also negative characteristics in the operation of a gas flow device:
- installation must be carried out by a specialist;
- for preventive purposes, carry out regular maintenance;
- Carefully monitor the device to ensure that there are no possible leaks of explosive gas.
Types of ignition
The speakers differ in the automation of the ignition processes. It is divided into two types: automatic and semi-automatic. Automatic ignition is carried out by the device independently. Only one burner is built into the design. When the hot water tap opens, the flame ignites from the spark produced by the column. The power source can be electric ignition or batteries.
New types of dispensers have a hydraulic turbine that generates electricity when water is supplied, so the operation of the dispensers does not depend on the power supply. An electronic programmable unit is built in to regulate the water temperature.
Semi-automatic water heaters have two burners. The first one burns constantly and serves as an ignition wick. The flame is ignited using piezo ignition. The second (main) ignition occurs when the tap of the water supply system is opened. Each type of speaker is equipped with a security system. If the gas or water pressure is insufficient or the exhaust gases are poorly discharged, the device turns off and refuses to work.
The best flow-through geysers with a closed chamber
Water heaters of this type do not use air from the room in which they are installed. They are connected to coaxial or separate chimneys led outside through the roof or wall. Such speakers can only work when connected to the mains.

Advice from experts on choosing speakers for an apartment or home
If the speaker will be used in the bathroom - in a damp room - experts recommend choosing only semi -automatic models . Steam from hot water negatively affects the operation of all electrical components inside the column.
Vending machines can only be installed in the kitchen.
First, you need to determine the water consumption, and then use these values to select the power of the unit. Power must be selected with reserve.
should be correlated with the power of the column . If the pressure created by the pump is small, a too powerful column will not heat the water, but boil it. In the summer this is completely useless. To choose the right devices, it is recommended to make calculations before purchasing, and also take into account the number of water consumption points.
The best storage gas water heaters
These devices are similar in appearance to electric boilers, since they have a large reserve tank, under which a gas burner is installed.

How to install a water heater in a private house
Regardless of whether a new column is being installed or an old one is being replaced, all work is carried out only if several conditions are met. First, a new chimney is installed and communications are laid out. Then the efficiency of the hood is checked and installation of the equipment begins.

Connecting a gas water heater.
The stages of work will be as follows:
- Determining the room and specific location where the water heater needs to be installed;
- Marking the wall and drilling holes;
- We install dowels, the number of which is determined taking into account the maximum weight of the heater filled with water;
- Hanging the column and installing filters to ensure water purification and increase the service life of the equipment;
- Connection of Mayevsky cranes;
- Cutting a pipe and installing a fitting or tee in it;
- Installation of taps and soldering of connecting elements;
- First connect the column to the cold water supply pipe of the house using a hose and a sealant (oakum).
- Monitoring the tightness of connections, which requires opening the water, checking for leaks. If a problem is detected, the seal must be repacked and the nuts tightened. After this, you should also check the draft in the smoke removal system, the norm of which is in the range of 1.95–29.40 Pa. The value of this indicator is influenced by the parameters of the room.
The last stage is performed only by a specialist. First you need to connect the corrugation to the water heater and the chimney duct, and the gas pipe to the tap.
The water heater is attached to the wall using dowels, screws or clips. Now you should connect the gas pipe to the water heater, seal the joints, checking their reliability using a soap solution.
If the joint is not airtight, then by covering it with soapy water this will immediately become visible due to the appearance of bubbles. Tightness is achieved by tightening the connecting nut. During the initial start-up of the entire system, the tightness of the entire installation is checked and adjusted.

Gas block diaphragm
It is impossible to turn on the gas water heater if there is a rupture of the membrane
made of elastic and durable rubber: depending on the water pressure, it controls the flow of gas into the product.
Repair is associated with difficulties - finding a spare diaphragm, which is made of durable and elastic rubber, is very problematic in retail trade, and their cost from dealers is very high.
Advice! To replace a torn membrane, a silicone product is suitable - such a part is more reliable and lasts much longer.
In addition to the diaphragm, you should check the entire gas block of a working column; there are many parts there, and each one can break. There are many recommendations for disassembly and subsequent repairs that can be found on the Internet.
Is it possible to install the column yourself?
Strictly speaking no. The exception is situations when the owner of the apartment or house is a licensed specialist. Connecting a gas water heater with your own hands leads to several unpleasant consequences:
The punishment for an unauthorized installation and connection of a gas water heater is described in the Code of Administrative Offenses of the Russian Federation:
The fine for incorrect connection, resulting in damage to property, ranges from 15-80 thousand rubles. Not only administrative, but also criminal liability is provided. Independent dismantling and installation of gas consuming equipment is not permitted.
Installation standards and requirements
Installation work is carried out in houses or apartments with gas energy. SNiP 42-01-2002 and SP 42-101-203 clearly state the rules for installing a domestic gas water heater in a private house or apartment:
