The main criteria for choosing a gas water heater

A feature of a flowless gas-fired water heater is practically instant water heating to the set temperature. Therefore, one of the most important criteria for choosing this type of equipment is power. This parameter directly affects both the performance of the device and the maximum temperature to which the column can heat water.

But do not forget that the performance indicator is indicated in the nominal value and implies the passage of water when heated at about 25 degrees. For a family of 3-4 people, a column producing about 10 l / min is quite enough.

Gas type (liquefied gas or trunk) is a key factor in choosing a water heater for installation in a non-gasified building. Therefore, pay attention to the labeling of the equipment and the manufacturer's recommendations.

Connecting a flowing gas water heater to a cylinder in an apartment

The units required for reconnecting the water heater from main gas to liquefied gas are not always included in the package. Parts may need to be purchased separately

A significant role in the reliability of the device is played by heat exchanger type.

This node is classified according to the material from which it is made:

  • Steel heat exchangers significantly reduce the cost of the column, are resistant to corrosive processes and are quite reliable. However, parts of this type weigh a lot, which affects the mass of the entire structure.
  • High purity copper heat exchangers are optimal. The assembly of this material is characterized by high efficiency, excellent heat dissipation and corrosion resistance.
  • Copper with a high content of impurities - a sign of an inexpensive column. This is a completely acceptable material, however, impurities in the metal significantly reduce the service life of the water heater, prevent uniform heating of the heat exchanger and most often require renovation.

From type of ignition not only the convenience of using the water heater depends, but also the economy of gas costs. So, a simpler piezo ignition, which implies starting the column after pressing a button, increases the gas consumption by about 20%. It is this amount of blue fuel that is wasted due to the constantly working igniter.

Electric ignition from batteries or the network is more economical, since it is carried out directly at the moment of opening the tap. But batteries need to be changed occasionally.

Columns with auto-ignition from a spark produced by a hydraulic turbine are no less economical. However, such models are sensitive to the pressure in the water supply system and the quality of the water itself.

Gas water turbine

A hydro turbine in a gas column is one of the most capricious units. Therefore, water heaters with a similar type of ignition are not recommended to be installed in houses of an old fund, since worn-out water pipes are an additional source of contamination of parts constructions

Security systems - one of the most important complexes in the design of the column. Availability gas control - a prerequisite for operation. Additional functions of the device will also be useful, for example, protection against freezing of the media, the presence of check valves that keep the device from surges pressure in the water supply etc.

The main sensors for controlling the gas column are:

  • heat exchanger temperature indicatorblocking heater operation at dangerously high temperatures;
  • gas controlthat interrupts the fuel supply when the flame is extinguished;
  • flue gas temperature sensor in models requiring a chimney connection.

Control type column is an exclusively subjective parameter of choice, which cannot be said about the method of changing the temperature of the carrier.

The water heater may have flame modulation or work with constant power. The latter implies temperature regulation in accordance with the water pressure, which is not always convenient. Modulation, on the other hand, allows the burners to deliver a user-specified temperature even with a decrease in the water pressure when the tap is partially closed.

Detailed recommendations on choosing a good gas water heater from an experienced master are presented in the video below:

The above rating of top models from trusted manufacturers includes those that are optimal for domestic conditions. devices that will reliably and efficiently heat water even with improper functioning of the general water supply and gas system.

A gas water heater that can be installed without being connected to a chimney remains a real boon for most buyers. Such models are distinguished by a fairly simple installation, stable operation and rich functionality.

But do not forget that a gas water heater is a dangerous equipment, therefore it is very important for speaker connections invite a specialist to help avoid trouble. And also do not forget about the rules fire safety when using it.
