First, it is important to understand What is the principle of operation of the device for heating. This will make a thoughtful choice in the future. For heating water are heating elements - heating elements. After the cold water enters the water heater, the heating elements heat it up to the set temperature. Two principles of operation of the heating elements are used:

  1. Wet. During the work there is a contact with water.
  2. Dry. For protection against water, a sealed flask is used.

In the first case, the problem is that scum appears over time. It must be removed from the boiler every year. The second option - dry - more reliable, but at the cost of such a boiler will come out almost twice as expensive.

A thermostat is provided in the construction of the boiler. Thanks to him, the device stops heating after the water reaches a certain temperature. After the water cools down, the device starts working again. Usually, the required temperature regime sets the landlord.

There are models that, using electronic control, allow you to control the heating intensity, taking into account the time of day.

It is worth remembering that in the presence of a boiler, energy is often used uneconomically. To avoid this, some turn off the boiler for heating or transfer it to the minimum heating mode.

Regarding the anti-corrosion coating, it is worth noting that enamel is an inexpensive, but most often used option. True, there is no guarantee that this coverage will serve for a long time. If there are constant temperature drops, then cracks appear in the tank and rust appears. In this case, it is recommended not to heat the water above 60ºС. But this is not an option, because this temperature increases the growth of bacteria. There are options with a coating of silver ions, but these are expensive models.

There is an option to purchase a stainless steel boiler. This material is not affected by corrosion and it lasts much longer - more than 10 years. But the price of such a model will be high.

  • Water cools slowly.

Another option is slim. Many of them have a thin and elongated shape. Their advantage: oversized and relatively large hot water supply.

For a family with children, a 120-liter boiler will be a practical option. Sometimes even it is not enough. It takes 7 hours to heat the water.

The figures given are averaged and depend on the power of the heating element.
