Heat pump water heaters

Refrigerant circulates through a closed loop. An evaporator coil absorbs heat from the surrounding air, even in cooler conditions. A compressor raises the refrigerant's temperature, and a heat exchanger transfers that heat into the water.

An insulated tank stores the hot water until you need it. The system uses electricity to move heat rather than generate it, reducing energy use and running costs compared with electric resistance heating. It works especially efficiently in moderate to warm climates.

• Energy efficiency

  Moving heat takes less electricity than heating water with resistance elements. This can reduce your household's energy use.

• Cost savings

  A higher purchase price can be offset by lower energy bills over the heater's life. Compare upfront and running costs together.

• Environmental benefits

  Using less electricity can reduce the greenhouse gas emissions associated with heating your water.

• Versatility

  Models serve a range of climates, including cold regions. Hybrid units can switch to electric resistance heating in very cold conditions to maintain hot-water supply.

• Incentives and rebates

  Available government and utility incentives, rebates or tax credits can reduce the purchase cost.

• Longevity

  With proper maintenance, a heat pump unit can provide years of service and may outlast a traditional water heater.

• Quiet operation

  Quiet-running models suit homes where equipment noise is a concern.

• Improved air quality

  The heater removes moisture from the surrounding air as it runs, helping indoor comfort and air quality.

• Smart features

  Some models offer programmable settings and mobile apps for remote monitoring, control and energy savings.

We compare your household's hot-water needs, installation space, climate and budget to determine whether a heat pump water heater fits your home and which model to choose.
