Installing a heat pump water heater is very similar to installing a standard water heater. It is still supplied with water by your main cold water source. The hot side gets connected to the hot water distribution pipes. Installers must ensure that the proper wiring and correct circuit breaker is in place.
Depending on the code, an electric disconnect may be installed for quick and easy turn off. Furthermore, the area the unit is installed in must have a drain nearby so that the condensation will have a place to be drained. If a drain is not nearby, a condensate pump could be installed to handle the discharge of water.
Generally speaking, a heat pump water heater must be installed in a location that is at least 1,000 cubic feet. Often, a heat pump water heater may be installed in smaller areas but must have vents or louver doors installed so the heat pump water heater has an adequate volume of air. Additionally, this space must maintain a temperature above 40 degrees year round. The higher the average temperature, the more energy efficient the heat pump water heater will be.
