Unfortunately, even in the 21st century, there are often interruptions in the supply of hot water. This applies not only to small towns, but also to large cities. That is why for the past few years every second person has been trying, if possible, to install a water-heating tank at home, that is, an individual boiler. Devices of this type differ in size, shape, device and principle of operation. The most important thing is that after connecting it, the apartment or house is completely independent of the centralized supply of hot water. The only condition is cold circulation.

There are two types of water heating tanks:
- Open. Able to work even in the absence of pressure in the system. Water supply is possible only at one point. Can be installed in places where there are constant interruptions in water supply.
- Closed. A water-heating tank of storage type is capable of providing hot water to both a bathroom andand the kitchen, subject to a single piping. Heating is carried out by an electric heating element. These devices are cumulative. They automatically collect the required volume of liquid and heat it up to the set temperature. The only thing that can be called a disadvantage is that hot water is distributed only when there is pressure in the system.
Water heater device
The storage tank (water heating) consists of seven elements:
- Case.
- Inner tank.
- Thermal insulation.
- Spout with a divider for cold water.
- TEN (heating element).
- Temperature sensor.
- Magnesium anode.
- Hot water connection.
It is important to pay attention to thermal insulation when purchasing a tank. For devices that are designed for a water volume of less than 200 liters, the layer should not be less than 5 cm thick, for devices with a larger capacity - about 10 cm. As a rule, polyurethane or foam rubber is used for thermal insulation.
The storage tank is most often made of high-class metal, very rarely - of plastic. Stainless steel is considered to be the most reliable. However, such tanks belong to an expensive price category. Their surface in budget options is enameled. There are also models with ceramic, glass-porcelain coating with the addition of titanium or silver. As a rule, the thickness of such a coating is about 2 mm. The use of these materials ensures the quality and reliability of the water heater.
