<P>PROBLEM TO BE SOLVED: To improve heating capability and heating efficiency of a water heater. <P>SOLUTION: The water heater (1) includes: a refrigerant circuit (2) having a compressor (11), a radiator (12), an expansion mechanism (13), and an evaporator (14); and a water flow passage (3) for circulating water so as to heat-exchange with a refrigerant flowing in the radiator (12). The water heater (1) includes a Peltier element (21) having a first heat transfer part (21a) on the heat absorbing side for absorbing heat from a high pressure refrigerant which has radiated heat in the radiator (12) of the refrigerant circuit (2) and a second heat transfer part (21b) on the heat radiating side for heating the water in the water flow passage (3). <P>COPYRIGHT: (C)2012,JPO&INPIT |
