Switch to an Electric Water Heater

heat pump water heater people

Switching to electric is better for the environment, your wallet, and your health. Be part of the community for change by upgrading your water heater.

Heat pump water heaters (HPWH) use electricity to move heat from one place to another rather than generating their own heat, like a refrigerator working in reverse. This makes them three times more efficient than other water heaters, according to the Department of Energy, and provides you a great opportunity to take local climate action in your home. The City encourages the community to consider home electrification, by shifting away from carbon-based fuels to electricity for space and water heating, transportation, and cooking. Benefits of switching to an electric heat pump water heater include:

Environmental: 90% of homes in Palo Alto have gas-powered water heaters, making water heating one of the largest sources of greenhouse gas (GHGs) emissions in Palo Alto homes. Gas water heaters produce GHGs while electric heat pump water heaters powered by Palo Alto's 100% carbon neutral electricity have a zero-carbon footprint.
Save Money: Because of their high efficiency, the costs of heating water with an electric water heater are lower than the cost of heating water with a gas tank water heater.
Health & Safety: Burning natural gas creates combustion gases such as nitrogen dioxide, carbon monoxide, and formaldehyde. Switching to an electric water heater eliminates the risk of back-drafting these unhealthy gases into your home.

Step 4.Review Your Estimate and Choose a Payment Option

After your site assessment, you will receive a cost estimate for your heat pump water heater project via email from Synergy. Choose one of the two payment options based on your estimate:

$2,700 due upon completed installation.

FAQs

What tax credits are available for heat pump water heaters?

You can claim 30% of the heat pump water heater project cost, up to $2,000. Please consult a tax advisor and learn more on the Energy Star website.

Will a heat pump water heater work when it’s cold?

Heat pump water heaters can work in extremely cold climates, including areas where it snows. In the cold, the efficiency and rate at which the water heater heats water again (recovery rate) may be lower. If the water heater’s recovery rate can’t keep up with demand, it will switch to a heating element to ensure there’s enough hot water.

What happens to a heat pump water heater in the event of a power outage?

The heat pump water heater will continue to supply the remaining hot water in the storage tank, although it will no longer produce hot water because neither the heat pump nor the resistance heating element will work without electrical power. When power is restored after the outage, the water heater will generally revert back to the most recent user settings.

What are the maintenance requirements for heat pump water heaters?

Maintenance requirements are not difficult, but they are important. Many water heaters have air filters that should be cleaned regularly. On some units, the air filter is located on the top and extra clearance is needed to ensure that the filter can be properly cleaned. Refer to product manuals for more information regarding proper maintenance.

Where can I install a heat pump water heater?

Because heat pump water heaters use the surrounding air to heat water, they work best in areas with at least 700 sq. ft. A garage, basement, outside facing closet, or large utility room that doesn’t need to stay warm are great options for installation.

Act Before It Leaks

Gas tank water heaters last between 8 to 12 years and gas tankless water heaters last between 15 to 20 years. Make sure to replace your water heater before it leaks, makes noises, or leaves you with no hot water.

Check the age of your water heater
