Heat Pump Water Heaters: A Simple Guide for East Bay Homeowners

The most efficient way to heat water — and one of the easiest electrification wins.

Updated February 11, 2026 · East Bay Heat Pumps

How they work

A heat pump water heater — also called a hybrid water heater — pulls heat from the surrounding air and uses it to heat the water in the tank, rather than burning gas or using electric-resistance elements. It's the same principle as a refrigerator, run in reverse.

How much they save

Because they move heat instead of generating it, hybrid water heaters use up to 70% less energy than a standard electric tank. That efficiency, combined with rebates, makes them one of the quickest-payback electrification upgrades for many homes.

Where they can go

They're commonly installed in garages, basements, and utility rooms. They need a reasonable volume of surrounding air to draw heat from and a condensate drain. A conversion from gas may also require a new electrical circuit — all of which we handle.

Is one right for you?

If your current water heater is aging, or you're planning to electrify your home, a heat pump water heater is usually an easy call in the East Bay's climate. We'll assess your space and hot-water needs and recommend the right capacity.
