Want hot water at a lower cost? 

A heat pump water heater uses heat pump technology to move heat from one place to another instead of generating heat directly.  This makes them two to three times more efficient than conventional electric resistance water heaters. A super-efficient heat pump water heater may reduce energy waste and hot water costs by 50 percent or more.

All EWEB electric customers may be eligible for a rebate to install a new heat pump water heater. 

Things to consider when installing a heat pump water heater

Heat pump water heaters can be installed in a variety of locations, including a garage, utility room or basement. Systems where the heat pump is integrated or stacked on top of the water tank are most common, but split systems are also an option. Please consider the following when determining whether an integrated heat pump water heater is right for you:

  • Sound. Heat pump water heaters generate sounds similar to the background noise from a portable fan (around 45 decibels).
  • Cool air. While in operation, heat pump water heaters release cool, dry air into the surrounding space. Ducting can be used to exhaust the air to the outside. 
  • Space. Heat pump water heaters typically need around 1,000 cubic feet (10'x10'x10') of airflow around them to operate properly. Some manufacturers may require less airflow and units can be installed in smaller areas if ducting or other airflow strategies are used.
  • Size/height. Heat pump water heaters may be slightly larger than standard water heaters (60 inches tall or more). Also, some units may be required by the manufacturer to have additional top clearance.
  • Condensate. Heat pump water heaters can release condensate. It is important to drain any condensate via a sloped drainage system, a condensate pump, or connection to a plumbing drain.
