BATTERY-POWERED HOT WATER RECIRCULATION PUMP
A relatively small water pump-DC motor combination, powered by batteries, provides sufficient pump power to create the flow between the hot and cold water lines necessary to maintain a substantially immediate hot water response when the hot water tap is opened. The pump is controlled by a thermal sensor signaling the pump to commence operation when the temperature in the hot water line upstream of the hot water tap is less than a predetermined value. Preferably, each of the batteries is rechargeable, most preferably utilizing a wireless system, where the power source is a distance away from the pump battery, to provide additional protection against electrical short circuits in the presence of water. Commonly available batteries of between 10 and 24 Volts can be used.
