Next to heating your home, heating your water consumes the most energy. An estimated 25% of your electric bill is used to heat water for your daily needs.

About Heat Pump Water Heaters

Heat pump water heaters are highly efficient. They can cut water heating energy consumption by 60% compared to standard electric water heaters. Rather than generating heat by burning fuel (electric resistance), heat pump water heaters move heat from one place to another, by heat transfer, the same technology used in heat pumps for home heating. Electric heating elements are used only when needed.

  • To find out if a heat pump water heater is right for you, visit Hot Water Solutions for helpful tools and resources.
  • When selecting a water heater, pay attention to Energy Factor (EF). This is a measure of its overall energy efficiency and is based on the amount of hot water produced per unit of fuel consumed over a typical day. The higher the EF, the more efficient the water heater.
  • Also consider the warranty, whether the size of the tank to meet your needs, and the First Hour Rating (the amount of hot water in gallons the heater can supply per hour).
