Installing a geyser is a great opportunity to no longer worry about unscheduled (or planned) disconnection of hot water in the house. Now hot water will depend only on the capabilities of the water heater. Gas water heaters do an excellent job of providing several taps with hot water at once and maintaining the required temperature.
For the correct choice of a water heater, it is important to determine which criteria are key and which are secondary. It is also recommended that you familiarize yourself with the list of the best water heaters, compiled from user reviews.

What are the criteria for choosing a gas water heater
There are several main criteria for choosing a water heater. It's hard to say which one is more important. All of them have a great influence on the final efficiency of the gas column.
- An important criterion is column performance... It is expressed in the amount of water that the device is able to drive through itself within one minute. The required performance is calculated based on the number of catchment points. It is estimated that one mixer has a flow rate of about 7 l / min. To provide two points with hot water, respectively, you will need a column with a capacity of twice as much, that is, approximately 13 l / min.
- Directly related to performance thermal power... It is estimated in kW. In terms of thermal power, the units are divided into weak (17-20 kW), medium (20-26 kW) and powerful (over 26 kW). And if a weak speaker is quite enough for a small apartment, then a really powerful unit will be needed for a large private house.
- How the speaker is fired up has a direct impact on the comfort of its use. Ignition can be manual, piezoelectric and electronic. Manual is now very difficult to find, but it may be present in older models. Piezo ignition is considered the most common, due to its cheapness and convenience. The difference from the manual one is that there is no need to light the wick on your own. Everything is done automatically at the push of a button.
- As heat exchangers the columns use radiators made of steel, purified copper or ordinary copper. Purified copper is most preferred. It will provide the highest efficiency of the unit.
- Since any manipulations with gas are activities of increased risk, safety is given an important role in the creation of gas water heaters. All kinds of sensors and automatic shutdown systems will not only ensure the stable operation of the device, but also preserve the life and health of apartment residents.
Rating of manufacturers of gas water heaters
There are several well-known manufacturers who have been creating very high quality and safe water heaters for many years. Most of the companies are located in Europe. Italian brands can be distinguished Zanussi and Ariston, which are famous for their household appliances all over the world. The Swedish company keeps up with them Electrolux, and a manufacturer from the Czech Republic Mora... The devices of these companies are highly reliable and have a wide range of products.
This list would not be complete without the home appliance giant, the German company BOSCH... The name of this brand has long been on everyone's lips, thanks to the highest build quality and durability of their products.
Famous car brand Hyundai also did not stand aside. The water heaters of this company are distinguished by their innovativeness and effective design.
There was also a place in this list for a domestic manufacturer. Company BaltGaz since 1995 has been actively developing in the field of gas appliances and offers customers products of very good quality.
