Select gas column

The Russian market of water heaters is represented by various models from leading manufacturers. However, in terms of profitability, the individual source of hot water supply - the gas column - is definitely leading. Reviews of the owners emphasize their aesthetic design, ease of operation, small size, long consumer life and economical fuel consumption. The choice of a gas column is not an easy process that requires knowledge of the basic characteristics of water heating units. In large supermarkets, there is a huge range of water heaters, which differ in their properties and functionality. In this review, try to figure out how to choose the right gas column.

The device and mechanism of operation of the gas water heater

Before we investigate how to choose a gas column for a dacha and an apartment, let us consider the distinctive features of a instantaneous water heater. These devices are distinguished by the fact that water is directly heated in a copper heat exchanger with a burner flame. The temperature of the water is maintained by changing the intensity of the flame.

The main modular elements include:

  1. A power unit that coordinates the work of all nodes and provides a multi-stage control system.
  2. Gas and water regulation device for safe and optimal operation of the device in a wide power range.
  3. Modular burner.
  4. Display to indicate the temperature of the heated fluid.
  5. A heat exchanger designed to provide heat transfer from heated gases to running water.
  6. Chimney with a thrust sensor.

Two pipelines are supplied to the body of the water heater: one supplies cold water and the other, respectively, gas. The lower part of the device is equipped with the main and pilot burners. When you open the tap with water through the valve enters the gas. It causes a fire from the pilot burner to the main. The water is thus heated, passing by spiral tubewhich is located in the heat exchanger. In this case, the emissions of harmful substances volatilize through the chimney, and the hot liquid enters the faucet. Automation of processes in the column allows you to quickly get heated water.

Basic selection parameters

To consider how to choose a gas burner for the room, let's get acquainted with the main distinctive features of heating devices. They differ in appearance, type of combustion chamber, power, kind of ignition, gas pressure in the system, different removal of combustion products and additional functional characteristics.

Types of combustion chambers

Geyser can have open and closed combustion chamber. In the first types of equipment, the flame is burned with air that comes from the room. For this, a bottom fence is provided. Combustion products are removed through a special chimney, which is in any apartment.

Columns with closed chambers use oxygen from the street to support the fire.Coaxial chimney is mounted with a water heater. As a result, the combustion products are removed using the built-in fan. Devices have a complex structure and high cost.

Note! For closed speakers, power is used to operate the fan. In the event of a power outage there will be no light or hot water.

Water heater power

The next important parameter that the user should pay attention to when choosing a gas water heater is power. It depends on the performance of the device. This characteristic shows the amount of water that the device can heat over a certain period of time.

There are three categories of units with power:

  • low - 17-17 kW;
  • average - 22-24 kW;
  • high - 28-31 kW.

Depending on the tasks that the device must solve, choose the technical characteristics of the water heating device. Powerful geyser need to work several water pointsLow-power models tend to provide hot water in the kitchen or shower room.

Attention! When choosing a water heater with a burner, remember that the performance is indicated taking into account water heating to a temperature of 25 degrees. If it is necessary to increase the temperature of heating with a small head, then the performance will be different than the one stated in the device passport.

Type of ignition

Depending on the method of switching on the gas column, there is electronic, manual ignition and piezo-ignition. The times when the wick was lit with matches were gone. Now you can ignite the burner automatically or using the buttons. Consider each of the options.

  1. Ignition from batteries. It turns on automatically after the tap opens. The energy source is batteries. Their resource lasts for 3-4 months.
  2. Ignition from hydro turbine. This type of igniter is used in expensive models. The source of energy is an electric generator. This option is suitable for those who have a water pressure of more than 0.35-0.5 bar.
  3. Piezo ignition. With the help of a special button with a piezo element, the wick is ignited. Since the location of the button is inconveniently located, it is difficult for the owners to use Piero ignition.

 Battery ignition

Device control

Gas water heater must be not only functional, but also convenient to use. It can be regulated, in addition to the level of gas supply, its pressure. In this case, the column will operate with reduced water pressure in the faucet. Availability liquid crystal display will give the opportunity to see the main parameters of the device:

  • outlet water temperature;
  • flame modulation;
  • error codes for instrument malfunction and other parameters.

Column safety

Despite technological progress, this option when buying a gas column should be considered. How to choose a safe gas stove? Some mandatory requirements apply to the device:

  • in the event of interruptions in the supply of gas or water, the unit should automatically shut down;
  • if the gas supply is resumed, there should be no leakage;
  • in case of weak traction, the unit automatically shuts down.

To meet these requirements, manufacturers equip the device with special sensors.

  1. Ionization sensor. If the flame goes out, the system turns off the gas supply itself.
  2. Burning sensor. It performs the same function as the previous device, if not triggering the ionization sensor.
  3. Waste safety valve designed to control water pressure through pipes.
  4. Flow sensor. The task of this function is to automatically turn off the device if the tap is closed and vice versa.
  5. Traction sensor. Prevents people from carbon monoxide poisoning in the absence of traction.
  6. Low pressure sensor. Thanks to this protection system, the column will not turn on if the water pressure is low.
  7. Overheating sensor. The main task is to control the water temperature: if it rises, the equipment is turned off. This additional protective function prevents pipe rupture.

When buying, consider the presence of all these sensors. If one of the listed devices is not present, then the column cannot be called safe.
