Instantaneous water heater M 3..7

Electric mini instantaneous water heater, open-outlet design, hydrauli­cally controlled with effective bare wire heating system with low power rating for supplying hot water to one wash basin. The attractive compact appliance matches perfectly all wash basins and heats the water directly as it flows through the appliance, without wasting energy in standby operation. The economically set flow rate ensures maximum efficiency. Higher power ratings > 5.7 kW also allow the appliance to be installed at a kitchen sink.
