Perfect for everyday hot water supply.
An electronically controlled continuous-flow heater with three bare-wire heating elements. The slight vibration prevents lime-scaling. The twin-power technology means the rated output of the DEE 1821 is switchable (18/21 kW). The rotary controller is a quick and easy way to select different temperatures: for washing hands, showering, washing dishes, etc. The installation template makes the unit compatible with the predecessor DEE ..02, DEE ..03 series.
