Heat pump water heaters
installed in the Inland Empire.

If you would like to lower your energy bills, a hybrid heat pump water heater is worth a look, and we are happy to walk you through it. Heat pump models use 60 to 70% less energy than electric resistance models. SCE and some city-owned utilities may offer rebates, and we check what’s open for your home.

What heat pump water heater rebates are available?

SCE and city-owned utilities (like Riverside Public Utilities) sometimes offer heat pump water heater rebates. They change often, so we check what your utility offers before you decide.

The step most plumbers skip

Expansion tank
air charge.

When water heats up, it expands. In a home with a pressure regulator or a check valve on the main line, that extra water has nowhere to go, so an expansion tank takes it in. Inside the tank is a cushion of air, and it only works when its air pressure matches your home’s water pressure. A heat pump water heater stores hot water in a tank just like a standard heater, so it needs the same protection.

Expansion tanks are pre-charged at the factory (commonly 40 PSI, depending on the brand), but many Inland Empire homes run 60 to 80 PSI. Installed straight out of the box, the tank fills with water and stops doing its job. That puts extra strain on the water heater, the relief valve and every fixture in the house.

Whenever an expansion tank goes in, we measure your home’s water pressure first and set the tank’s air charge to match. Most plumbers skip it. We never do.

How it works

It moves heat instead of making it.

A heat pump water heater pulls heat from the air around it and puts it into the water, much like a refrigerator working in reverse. Because it moves heat rather than creating it with a heating element, it uses far less electricity than a standard electric water heater. Most models also have a backup element for times of heavy hot water use.

The Inland Empire is a good fit for heat pump water heaters. Garages stay warm most of the year, which is the kind of space these units work best in.

Is it right for your home?

What to check before you decide.

  • Space and air: the unit needs room around it and enough air to draw heat from, so a garage is often the best spot
  • Power: most models need a 240-volt circuit; some plug-in models work on a standard outlet
  • A drain: the unit makes condensate water, which needs a place to drain
  • Noise: it has a fan and compressor, so it is not the best fit right next to a bedroom

Can’t sing Sweetwater Plumbing’s praises enough. When I first inquired about replacing my 75-gallon gas water heater with an 80-gallon heat pump water heater, I was impressed with John Howe’s product knowledge and ability to understand my goals. (I was very…

Common Questions

Frequently asked questions.

How does a heat pump water heater save energy?
It moves heat from the surrounding air into the water instead of making heat with an electric element. That uses much less electricity than a standard electric water heater.
Can a heat pump water heater go in my garage?
In the Inland Empire, a garage is often the best spot. The unit needs space around it, a power circuit and a place to drain condensate. We check your garage before recommending one.
Are there rebates for heat pump water heaters?
Sometimes. SCE and some city-owned utilities have offered rebates, and they change often.
Will I have enough hot water?
We size the unit to your household. Most models also have a backup heating mode for busy times.
Can I replace my gas water heater with a heat pump model?
Often, yes, but it may need a new electrical circuit and a drain. We look at your home and explain what the change would involve.
