A condensate handling assembly comprises a collection container for receiving and retaining condensate, a heating container for receiving condensate from the collection container, and a heating device for raising the temperature of condensate in the heating container to pressurize condensate in the heating container. A transfer conduit interconnects the collection container and the heating container, and a one-way valve is disposed in the transfer conduit for permitting flow of condensate from the collection container to the heating container. A level sensor senses the level of condensate in the collection container and activates the heating device upon the condensate in the collection container reaching a selected level. A discharge conduit extends from the heating container and is in communication with a selected water reservoir, and a one-way valve is disposed in the discharge conduit for releasing condensate from the heating container for flow to the reservoir upon pressure of the condensate in the heating container exceeding pressure in the reservoir.

Condensate handling assembly and method

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.
