FUNCTION DESCRIPTION
The heater is designed for accumulation heating of service water using electricity or thermal energy via an
exchanger (for the combined design only).
Water is heated by an electric element (or a heat exchanger) in an enamelled thermally insulated accumulator at
the time defined by the power supplier. The element is at the time of heating controlled by a thermostat the
temperature of which can be adjusted continuously (within the range between 5°C and 74°C). Once the selected
temperature is reached, heating interrupts automatically.
consumption. The tank keeps constant pressure of water from the water main. If the combination faucet hot water
valve is opened, water from the water supply conduit pressed out by cold water pressure flows out of the heater.
Hot water flows out through the top part, and water flowing in remains in the bottom part of the heater. Pressure
principle allows hot water withdrawal at any place from the heater (Fig. 1).
Water accumulated in the tank is then used for
