Water heating tank: types, description, manufacturers

Unfortunately, even in the 21st century there are often interruptions with hot water supply. This applies not only to small towns, but also to large megacities. That is why for the last several years every second has tried to install a water-heating tank, that is, an individual boiler, if possible. Devices of this type differ in size, shape, device and principle of operation. Most importantly, after its connection, the apartment or house is completely independent of the centralized supply of hot water. The only condition is a cold circulation.

Kinds

Tanks for heating water are of two types:

• Open. Are able to work even in the absence of pressure in the system. Water supply is possible only for one point. It can be installed in places where there are constant interruptions to water supply.
• Closed. A hot water storage tank is capable of providing hot water both to the bathroom and to the kitchen, provided there is a single piping. Heating is carried out by an electric heater. These devices are cumulative. They automatically gain the required volume of liquid and heat it up 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:

• Housing.
• Internal tank.
• Thermal insulation.
• A branch pipe with a divider for cold water.
• Heating element (heating element).
• Temperature sensor.
• Magnesium anode.
• A branch pipe for hot water.

It is important, when purchasing a tank, to pay attention to thermal insulation. For appliances that are designed for a volume of water less than 200 liters, the layer should not have a thickness less than 5 cm, on appliances with a greater capacity - about 10 cm. Typically, polyurethane or foam rubber is used for thermal insulation.

The accumulation tank is most often made of high-grade metal, very rarely - of plastic. The most reliable is considered to be stainless steel. However, such tanks belong to an expensive price category. Their surface in budgetary versions is covered with enamel. Also there are models with ceramic, glass-porcelain spraying with the addition of titanium or silver. Typically, the thickness of such a coating is about 2 mm. The use of these materials ensures the quality and reliability of the water tank.
