Instantaneous water heater MBH 3..7

Electric mini instantaneous water heater with highly-efficient bare wire heating system for supplying hot water to a single point of use, i.e. one handwash basin or sink. The attractive small appliance perfec­tly matches all wash basins and heats the water automatically as it flows through it, without wasting energy in standby operation. The economically set flow rate ensures maximum efficiency. The heater can easily be installed directly to a standard mixing tap. Our special tap aerators guarantee efficient and economic flow results.
