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?
Heat pump water heaters need 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.
