How do I model a Heat Pump Water Heater?

Navigate to the DHW/Boiler library and create a new Water Heater.  Set the Water Heater Type to “Heat Pump”.  Enter the Volume, Energy Factor and Input Rate from the manufacturer’s specifications.  Note that sometimes the Energy Factor may be listed as the COP in the data.

Currently you cannot model a heat pump water heater that serves nonresidential occupancies since the CEC CBECC engine does not support that feature.

For residential projects (single family, multi-family, high-rise residential, hotel/motel), if a heat pump is rated by the Northwest Energy Efficiency Alliance (NEEA), you may check the “NEEA Rated”  box at the bottom of the editor and select a specific type of water heater.
