Three times more efficient than conventional hot water systems, heat pump water heaters transfer heat from the surrounding air instead of burning fossil fuels.
Heat pump water heaters are three times more efficient than conventional electric water heaters and can lower operating costs by 50%.
Lower pollution than heating water with oil, propane, natural gas, or electric resistance.
Save money on utility bills compared to a water heater that uses propane, oil, or electric resistance.
Provides dehumidification to the room where the heat pump water heater is located.
Wi-Fi controls enable homeowners to remotely control and monitor the water heater.
Heat is transferred from the surrounding indoor air into a hot water tank. Hot water is then piped throughout the home. When needed, an electric resistance coil in the tank will enable a continous supply of hot water and/or boost the temperature of the water.

Do you currently heat your hot water with oil, propane, or electric resistance? Are you interested in saving money on your energy bill?
Installing a heat pump water heater could save hundreds of dollars a year on your utility bill.
Is your existing hot water tank over 10 years old or reaching the end of its useful life?
Consider replacing your water heater before it fails or leaks all over the floor. A heat pump water heater can replace your existing water heater, and the installation can be done by a plumber.
Do you have space in your basement that stays above 50°F year-round?
Your heat pump water heater needs to be located in a minimally warm area with enough open space for air circulation to operate efficiently.
Do you want a hot water system with smart controls?
Many HPWH also have Wi-FI integration which enables alerts, service warnings and more active monitoring of the system. Leak protection systems are also increasingly common, automatically shutting off water to, or sealing up areas surrounding, a leak to prevent flooding.
Is your basement warm in the summer because your hot water is generated with an oil-fired heater?
It’s counterproductive to create heat in the basement in the summertime while trying to keep the rest of your home cool. A heat pump water heater efficiently uses heat from the surrounding air instead of combusting fuel onsite to create hot water.
