Go All Electric

To further align with the City’s climate goals and its commitment to a more sustainable community, PWP encourages customers to make the switch to all-electric appliances and equipment in order to eliminate greenhouse gas (GHG) emissions from buildings.

What is beneficial electrification?

Beneficial Electrification is the process of replacing the use of fossil fuels with electricity to reduce overall GHG emissions and energy costs. Examples include making the switch from an oil or natural gas furnace to an electric heat pump (building electrification), or switching from a gasoline-powered car to an electric vehicle (transportation electrification).

How does heat pump technology work?

Heat pumps use compressors and refrigerants to pull the “cool” or the “heat” out of surrounding air. Heat pumps are typically bi-directional, meaning they can be used to cool or heat a space. One of the most common examples is a refrigerator, a heat pump draws hot air from inside your refrigerator to the outside, which is why many refrigerators feel warm in the space between the wall and the back of the refrigerator.

The heat pump technology is currently used in several other all-electric appliances and equipment. A heat pump water heater draws heat from the surrounding environment to heat your water. A heat pump clothes dryer also draws heat from the surrounding environment to dry your laundry. Both heat pump appliances use the same process found in the refrigerator, but in reverse. Similarly, an air source heat pump (including mini splits), leverages the bi-directional process to cool or heat your home.

Please visit the Additional Resources section below for more information on all-electric appliances that utilizes heat pump technology.

Making the Switch to All-Electric Appliances

All-Electric appliances that uses heat pump technology include heat pump water heaters, air source heat pumps and heat pump clothes dryers. Since these appliances are powered only by electricity, making the switch reduces greenhouse gases, improves indoor air quality and maximizes energy efficiency. PWP offers several all-electric appliance and equipment rebates to help offset a portion of the costs for customers making the switch.

Things to Consider

On average, most clothes dryers and water heaters lasts for about 10-12 years, with furnaces lasting anywhere from 15-20 years. If you know your existing appliance or equipment is close to the end of its useful life, it is always a good idea to make the switch beforehand.

Electric System Requirements

A majority of homes in Pasadena were designed to operate on other fuel sources besides electricity. As you transition more of your home appliances and equipment to electricity, you will need to make sure that the existing electric panel has the capacity to accommodate the additional load. It is common for heat pump water heaters to require a dedicated 30 amp circuit and a 220/240V breaker, although some 15 amp models may be available. To understand what the next steps might be for your own home, please contact a licensed professional installer. PWP also offers a rebate to upgrade your electric panel, restrictions apply, please visit the program webpage for more details.

Space Requirements

Heat pump water heaters may need slightly more clearance than other tank units because it includes a compressor within the tank. The estimated space requirements can range from 700-900 cubic feet. As a reminder, the heat pump water heater unit will vent cool air, so non-conditioned spaces like garages are ideal locations. A license professional installer will be able to assist in evaluating the best option for your home.

Permits

Please contact the City of Pasadena Permit Center at 626-744-4200 for more information on required permits for appliance, equipment and electric panel upgrades.
