2.1. The appliance is designed for installation inside the buildings, in the household and utility
premises. It is intended for water heating to a temperature below boiling point, with the option of the
hot water's supply at several spots (Table 3) and further maintenance of the set temperature in the
automatic mode.
2.2. Water heating time depends on the volume of the water heater and the power of the heating
element.
2.3. Main elements:
- Inner tank;
- Thermal insulation of polyurethane foam providing minimal heat dispersion even when the water
heater power is off;
- Heating element;
- Temperature controller which allows you to set the desired temperature of the water heating;
- Thermostat controlling the temperature of water in the tank;
- Safety valve which is installed at the inlet of the water heater and serves to prevent the return of
