The Technology

HOW IT WORKS

Heat is transferred from the surrounding indoor air into a hot water tank. Hot water is then piped throughout the home. When needed, a backup source of heat in the tank will provide supplemental hot water

Things to Consider

If you answer yes to ANY of these questions, then a heat pump water heater is a good fit for your home

Installing a heat pump water heater could save hundreds of dollars a year on your utility bill.

Consider replacing your water heater before it fails or leaks all over the floor. A heat pump water heater can replace your existing water heat, and the installation can be done by a plumber.

Heat pump water heaters need to be located in a minimally warm area with enough open space for air circulation to operate efficiently.

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.
