<p>A water heater (10) in which water is heated by microwave energy. A tank (11) which holds water is separated by a horizontal partition (20) into a relatively small upper chamber (22) and a larger lower chamber (24). Incoming cold water enters the upper chamber (22) and is heated by a magnetron (32) which produces microwave energy. A transfert conduit (34) accommodates the flow of hot water from the upper chamber (22) to the lower chamber (24) when water is discharged from the lower chamber (24) through an outlet pipe (36). When the water in the lower chamber (24) cools, a pump (42) returns it to the upper chamber (22) for reheating. The pump (42) and magnetron (32) are controlled by thermostats (50, 52, 54) which maintain the water in the upper and lower chambers (22, 24) at different temperature levels.</p> |
