    • A water heater and storage tank assembly comprises a housing defining a chamber, an inlet for admitting cold water to the chamber, and an outlet for permitting flow of hot water from the chamber. A compressor is mounted on the housing and is removed from the chamber. A condenser comprises a tube adapted to receive refrigerant from the compressor, and winding around the chamber to impart heat to water in the chamber. An evaporator is mounted on the housing and removed from the chamber, the evaporator being adapted to receive refrigerant from the condenser and to discharge refrigerant to conduits in communication with the compressor. An electric resistance element extends into the chamber, and a thermostat is disposed in the chamber and is operative to sense water temperature and to actuate the resistance element upon the water temperature dropping to a selected level. The assembly includes a first connection at an external end of the inlet, a second connection at an external end of the outlet, and a third connection for connecting the resistance element, compressor and evaporator to an electrical power source.
    • 热水器和储罐组件包括限定腔室的壳体,用于将冷水引入腔室的入口和用于允许来自腔室的热水流动的出口。 压缩机安装在壳体上并从腔室中取出。 冷凝器包括适于从压缩机接收制冷剂并且围绕室缠绕以对室内的水进行热量的管。 蒸发器安装在壳体上并从腔室中移除,蒸发器适于从冷凝器接收制冷剂,并将制冷剂排出到与压缩机连通的导管。 电阻元件延伸到室中,并且恒温器设置在室中,并且可操作以感测水温并且在水温下降到选定水平时致动电阻元件。 组件包括在入口的外部端的第一连接,在出口的外部端的第二连接,以及用于将电阻元件,压缩机和蒸发器连接到电源的第三连接。
