Geyser selection criteria
In order not to make a mistake in choosing, before buying it is worth paying attention to a whole set of basic and additional characteristics of a water heater. This will help you to choose a truly high-quality and functional technique that is suitable specifically for your needs.
Key technical indicators
This category includes power, performance, material and quality of the heat exchanger and the number of sensors.
Feature # 1 - Type of Combustion Chamber
By the type of combustion chamber, all water heaters are divided into two categories: with an open chamber or atmospheric, and with a closed or turbocharged.
Atmospheric are considered more durable, since in such devices there is no complex automation. Turbocharged work thanks to electricity and turn on even with minimal gas pressure, but they are more expensive.
The method of removal of combustion products:
- Through the chimney. It is appropriate if the column is atmospheric. The chimney must be cleaned from time to time by the appropriate service.
- Across coaxial channel gas is forced out if a column with a closed chamber is installed. To do this, the column has a fan that runs on the network. This option is suitable for new buildings, since there is no chimney.
Owners should check traction status as often as possible. It is best to check with paper. Such a check should never be carried out with a lighter or match, otherwise an explosion could occur.
Feature # 2 - instrument power
The amount of heated water that you can get directly depends on this indicator. There is useful and consumed power. When choosing a device, pay attention to the useful power.
Feature # 3 - Performance
Productivity is the amount of water the column heats per minute. In order to correctly calculate the required performance, you need to know the pressure head.
This is pretty easy to do. It is necessary to record the number of cubes on the counter, turn on the water for 1 minute. After this time, tighten it and then record the indicators again. The difference between the second and first values will be the desired value.
If there is no counter, substitute a large tank. Today there are speakers whose performance is 5-6 liters. They are suitable for apartments with low pressure and old pipes. For two or three people, 12-14 liters will be enough.
Feature # 3 - Heat Exchanger
The durability of the column depends on the quality and thickness of the material of this part. Steel is durable but heavy. Such heat exchangers have a low cost, but are susceptible to corrosion.
Ordinary copper is short-lived. Highly purified copper heat exchangers have a higher efficiency compared to steel.
Such parts should be cleaned carefully and only with special means. If you choose the wrong detergent, the part may become worthless. For example, acid corrodes copper products and they subsequently begin to flow.
The rules and methods for self-service column are discussed in detail in this article.
To ensure safe use, users of the boiler use special parts:
- Water overheating sensor it will protect against boiling water, and the safety valve is responsible for emergency discharge of water if there is a lot of pressure in the pipes.
- Hydraulic valve protects column parts from overheating.
- Ionization and combustion sensors they are triggered if, after the burner has extinguished, gas still flows.
- Flow sensor turns off the water heater if the hot water tap closes.
- Traction detector It works if the chimney is clogged with garbage so that no one is poisoned by carbon monoxide. And if there is no necessary water pressure, then the reduced water pressure sensor is activated and the column does not turn on.
A lot depends on their quality. All these details will save not only the device itself from damage, but also your health.
Additional technology information
Also, when choosing a gas column, it is worth paying attention to additional characteristics. For instance, front panel appearance important as the black column does not fit into the white kitchen.
Area of bathroom or kitchen and the dimensions of the column itself. If the kitchen is small, and 3 people use water, then you should look for a place in the bathroom or donate the area.
Gas type. Pay attention to what gas is supplied to the house. If liquefied gas is supplied to the cottage, it is strictly forbidden to install a column operating on natural gas. Such a mistake could cause an explosion or poisoning.
Type of ignition. Old columns are turned on with a match, which sets the wick on fire. To date, these types of inclusion are used:
- piezo ignition made using the button on the device panel;
- electronic ignition - a spark from the battery occurs when the water is turned on;
- from the hydro generator - during switching on, a turbine is activated, which forms an electric current. And he creates a spark.
This indicator is not the main one, but the comfort of using the column depends on it.
More detailed recommendations on the choice of a gas column are given in next article.
Before installation of a geyser It is important that specialists evaluate the condition of the gas pipes, the pressure level and eliminate the malfunctions, if any. Such precautions are necessary to avoid gas leakage and poisoning of residents.
In addition, installation should be ordered only from professionals, because not only your health depends on this, but also the possibility of obtaining a guarantee for a gas appliance.

A gas water heater is my nightmare ((It may be that modern models are safer to use, but those that I remember from the 90s do not cause anything but goosebumps on my back. I have never heard from such a column took off into the air of the house. If there is no central hot water supply, it is better to put a boiler and sleep peacefully. I am generally surprised by people who still choose gas water heaters.
You, apparently, are just a very impressionable person and because of one or two cases that have sunk into your memory, you have a negative opinion. With proper use, there is no particular danger. And in the nineties, most gas water heaters worked fine and were completely safe, otherwise people would not have used them. Plus now there are practically no gas columns with manual ignition, now everything is with piezoelectric or electronic ignition, which is much safer. With regular maintenance and maintenance, there is no danger. In general, the risk is not greater than when using a gas stove in an apartment.
I also remember such cases. The water was just unpredictable. just black liquid could go, the filters could not cope, the speakers were boiling, humming like planes and taps were spitting boiling water. 5 cases in my memory such. It also happened that a man went swimming and just shut off the water. The column was supposed to stand on the igniter, but for some reason this did not happen and, again, the water began to boil.
Gas water heaters, like any device associated with the processing of gaseous fuels, require a bunch of permits from local authorities. And with us this often means the intrigues of the bureaucracy and the long paperwork.I would prefer an electric water heater, and it is even better to have a storage boiler instead of a flow one. Although, of course, everything has its pros and cons. It is necessary to select individually.
Seq, many would prefer a boiler, it really is in many respects more convenient than a column. But if a column was originally installed in the apartment, then you can’t dismantle it yourself, but the design of all the papers is such a gimmick - it’s easier to put up with the column. Here for a new home - definitely an electric boiler. Electricity charges, although higher, but the ease of use clearly justifies this.
