    To understand the concept of heat pumps, imagine a refrigerator working in reverse. While a refrigerator removes heat from a box and expels it into the surrounding air, a heat pump water heater takes the heat from the air and transfers it to water in an enclosed tank. They are called “hybrids” because in addition to a heat pump they also have traditional electric resistance heating elements for times when demand exceeds what the heat pump can produce.
Installation Considerations
   Because of their noise and cooling effect, heat pump water heaters are better suited to basements than living spaces, especially if there is extra heat available from a boiler.
   Remember that you’ll need a place to drain the condensate. This can be pumped outside or passively drained to a sink or floor drain lower than the heat pump condensate port.
    For optimum efficiency, install a heat pump water heater where the temperature stays above 45°F and provide at least 1,000 cubic feet of air space around the unit. This would be a typical 10’ x 15’ room.
     Be sure to give the unit the recommended clearances from walls to ensure adequate circulation.  Be sure the ceiling is high enough to accommodate the unit.
    Insulate the first six feet on incoming and outgoing pipe to minimize heat loss through distribution.
