Unfortunately, even in the 21st century, there are often interruptions in the supply of hot water. This applies not only to small cities, but also to large megacities. That is why for the last few years every second one has been trying to install a water tank at home , that is, an individual boiler. Devices of this type differ in size, shape, device and principle of operation. Most importantly, after connecting it, the apartment or house is completely independent of the centralized supply of hot water. The only condition is cold circulation.
Kinds
Tanks for heating water are of two types:
- Open. Able to work even in the absence of pressure in the system. Water supply is possible only at one point. It can be installed in places where there are constant interruptions in water supply.
- Closed. The storage water tank is capable of providing hot water to both the bathroom and the kitchen, subject to a single pipe connection. Heating is carried out by an electric heater . These devices are cumulative. They automatically gain the right amount of fluid and heat it to the set temperature. The only thing that can be called a drawback - the distribution of hot water is carried out only if there is pressure in the system.
The device of water heaters
The storage tank (water heating) consists of seven elements:
- Body.
- Inner tank.
- Thermal insulation.
- Branch pipe with a divider for cold water.
- TEN (heating element).
- Temperature sensor.
- Magnesium Anode
- Branch pipe for hot water.
When purchasing a tank, it is important to pay attention to thermal insulation. For devices that are designed for a water volume of less than 200 l, the layer should not have a thickness of less than 5 cm, for devices of 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. The most reliable is considered to be stainless steel. However, such tanks belong to the expensive price category. Their surface in budget options is covered with enamel. Also there are models with ceramic, glass-porcelain spraying 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 tank.
