ABSTRACT:
A water heater includes a metallic water tank having a generally vertical orientation in use. A tube for carrying a refrigerant fluid is heat-conductively bonded about the outer surface of the wall of the tank while held under tension. The tube is formed of a material having a coefficient of thermal expansion similar to the material of the tank. The tube extends from a position below a cold water inlet at the bottom of the tank to a position approximately 66% of the height of the tank. An evaporator is positioned for exposure to ambient conditions and has a passage for carrying the refrigerant fluid. A compressor is connected to the passage and to the tube to circulate the fluid through the tube and to the evaporator.
