The complete arbitrariness of housing and communal services officials in all countries of the former CIS has led to the fact that residents of apartment buildings in many cities spend almost the entire warm time of the year heating water for washing on a gas stove. The solution may be a gas water heater, but when you buy it, you should consider many factors.
Choose a gas column
A modern heater should be easy to use, at least relatively inexpensive and reliable. Unfortunately, in most cases you can say goodbye to dreams of cheapness. Excessively low cost indicates that this gas water heater was unlikely to be produced by any reliable company.
But much more important is that it should automatically turn off and on when closing / opening a hot water tap. Fortunately, the days when a gas burner had to be manually ignited to obtain warm water were gone . Most of these devices today require only a constant connection of electricity (for lighting a fire) and normal pressure in the water supply system.
It follows that a high-quality gas water heater should be as safe as possible. This is due to the fact that in our conditions constant shutdowns of gas or water are not uncommon. A quality appliance should automatically respond to any changes. For example, a drop in gas pressure, disconnecting from the gas pipeline. This will protect you from the very unpleasant consequences of its possible leakage when resuming filing.
Among other things, the exhaust system should also exclude the possibility of carbon monoxide poisoning. So, in the absence of traction, the column should also be turned off. If at least one of the above requirements is not met, then it is not advisable to buy such a gas water heater.
They are classified by the type of removal of combustion products. There are heaters with an open combustion chamber (ordinary chimney), with a closed one (forced exhaust of gases), as well as with the release of substances directly into the room where such equipment is installed.
Note! Despite the fact that such heaters are strictly prohibited for installation in residential premises, some unscrupulous sellers occasionally manage to sell them specifically for such purposes. Note that for household use, chimney household gas water heaters are best suited, since they do not need a lot of electricity, which would otherwise be spent on the operation of the hood.
To install it, you need not only a chimney, but also high-quality exhaust ventilation of the room. Such models are inexpensive, extremely easy to operate and repair. But remember that buying cheap Chinese heaters for $ 100 is not worth it, because in this case no one can give a guarantee of preserving your life and health.
If the apartment or house does not have good ventilation, it is preferable to choose models with forced removal of combustion products. The principle of their operation is based on the intake of air from the environment with the subsequent removal of gases there. By the way, the best gas water heaters of this kind are often combined in a single circuit with a water heating system for housing.
