Heat pump water heater (HPWH)
If you’re planning to transition to a clean energy home, your water heater is a great place to start. Nearly 60% of the methane gas used by homes is for heating water. Heat pump water heaters are clean, safe, and all-electric. Peninsula Clean Energy offers a rebate up to $3,000 to help customers make the switch to a heat pump water heater.
Get a 0% interest loan up to $10,000 with no credit check and no money down for heat pump water heaters through our Zero Percent Loan Program.
- Don't wait until your water heater fails catastrophically: if your water heater is at least 10 years old or you are planning a remodel consider a HPWH
- A qualified contractor can evaluate your home and help you understand factors that may affect the ease and cost of installation, including HPWH selection and location
- Rebates not only help offset costs of HPWHs but are also available for electrical panel upgrades, if needed
- HPWHs typically need more space when compared to gas water heaters and are best suited for installation in a garage, but may be installed in a closet if it is properly ventilated
- HPWH noise varies depending upon the model and may be mitigated through choice of location and/or sound-proofing
- Start today – demand for HPWHs is growing and contractor schedules and order times for popular models require advanced planning
Methane gas leaks and combustion of methane contribute to climate change and are unhealthy and potentially hazardous in the home. Heat pumps have been around for decades – refrigerators and window air conditioners both use heat pumps.
- Efficient: At least 3x more efficient than methane gas water heaters
- Safe: Heat pumps are all-electric – no gas combustion emissions or hazards
- Clean: Heat pumps powered by Peninsula Clean Energy is 100% clean
Peninsula Clean Energy rebates make it easier for residents in its member communities to transition to a clean energy home.

To be eligible for the rebate, you must own the property in San Mateo County or Los Banos where the HPWH is being installed. We offer two rebate amounts depending on the water heater type that your new HPWH is replacing. Below is the HPWH eligibility guidelines as stated in our rebate program terms & conditions:
- If you replace an electric resistance tank or tankless water heater, you are eligible for a $500 rebate. HPWH to HPWH replacements are not eligible.

The Bay Area Regional Energy Network (BayREN) is a regional program for the Bay Area’s nine counties focusing on energy, water and greenhouse gas reduction. BayREN’s Home+ program offers rebates for energy efficiency and electrification upgrades.
In San Mateo County, Peninsula Clean Energy’s heat pump water heater rebates and heat pump HVAC rebates are integrated with the BayREN Home+ program. This allows customers who work with BayREN participating contractors to apply for rebates from both agencies through a single application process (BayREN’s). The BayREN program administrator reviews the application and documents and sends them directly to Peninsula Clean Energy, so that you or your contractor don’t have to submit them twice.
If you are not working with a BayREN participating contractor or your project doesn’t qualify for BayREN rebates, BayREN does not have a role in your project. Application must be submitted directly through Peninsula Clean Energy’s Appliance Rebate application form in this case.
You can use any contractor you’d like. They do not have to be a BayREN participating contractor. In fact, self-installed/“DIY” projects are also eligible for the rebate.
However, in order to be eligible for BayREN rebates, you must use a BayREN participating contractor.
We recommend working with a BayREN participating contractor because they are highly experienced and will be able to submit the application on behalf of the customer for both BayREN and Peninsula Clean Energy rebates. If a contractor you want to work with is not a BayREN participating contractor, please encourage them to join the program!
Yes, self-installed / “do it yourself” heat pump water heater projects qualify for the rebates. Please note self-installed projects are still required to provide copy of the city permit.
You are not required to use the same contractor for the HPWH and electrical panel upgrade. However, the electrical upgrade rebate must be applied for at the same time as a heat pump water heater or heat pump HVAC rebate.
There are two methods of application: a single integrated application with the BayREN Home+ program if you are working with a BayREN contractor and your HPWH qualifies for BayREN rebate; and an application directly to Peninsula Clean Energy if you are not working with a BayREN contractor and/or your HPWH does not qualify for the BayREN rebate. Only one application should be submitted per customer/property. Refer to each respective section below for details.
Integrated application with BayREN Home+ program
- After installation, your BayREN contractor will complete and request your signature on a few rebate forms, including a Peninsula Clean Energy rebate form.
- Your contractor will then submit the application for you through the BayREN Home+ contractor portal. Only one application is needed to receive all applicable rebates.
- The BayREN Home+ program administrator will review and process the application. Once approved, the application will be forwarded to Peninsula Clean Energy.
- Peninsula Clean Energy will review your application and notify you when it has been approved.
- Rebate checks from BayREN and Peninsula Clean Energy will be sent separately. Rebate checks will go to whoever was identified as the rebate payee in the BayREN invoice form. Rebate payee can be the customer or contractor. If it is the contractor, the contractor is required to pass down the entire rebate amount to the customer. Note that for projects also participating in Peninsula Clean Energy Zero Percent Loan Program, the rebate payee must be the contractor.
Peninsula Clean Energy direct application form
**Please do not submit this form if you are working with a BayREN contractor and your upgrade is eligible for the BayREN rebate**
- After installation, submit your application through Peninsula Clean Energy’s Appliance Rebate application form. You may submit the application yourself or have the contractor submit the application on your behalf. For projects participating in Peninsula Clean Energy’s Zero Percent Loan Program, your contractor must submit this form on your behalf.
- Peninsula Clean Energy will review your application and notify you by email when it has been approved within 5 to 15 business days.
- The rebate check will be sent to you, the customer, at the mailing address provided in the application, unless the contractor was identified as the rebate payee. If the rebate payee is the contractor, the contractor is required to pass down the entire rebate amount to the customer. Note that for projects also participating in Peninsula Clean Energy Zero Percent Loan Program, the rebate payee must be the contractor.
If you are working with a BayREN contractor and the project is eligible for the BayREN rebate, the contractor must apply for you. The BayREN Home+ program requires the contractor to apply for the rebate on the customer’s behalf. That application will be forwarded to us.
If you are not working with a BayREN contractor and applying through our direct application form, you can apply yourself or the contractor can do it on your behalf. The application will ask who is filling out the application. Make sure to talk to your contractor about who will be submitting the application so that you do not submit duplicate applications. Duplicate applications will lead to longer processing times.
The rebate goes to the customer by default unless the contractor is identified as the rebate payee in the application. The rebate may only go to your contractor if it fully passed down as a discount to you and clearly itemized in their invoice.
Unfortunately, we do not offer rebate reservations at this time.
The average time to receive the rebate from the time of application is 4-5 weeks. Applications submitted through BayREN generally take about a week longer than applications submitted directly to us. You will receive an email from us when you rebate application is approved; from that point, you can expect the check in 2-3 weeks.
Unfortunately, they do not qualify. Rebates are only available for replacement/retrofit projects where the heat pump water heater installed is replacing a gas or other fossil-fuel powered water heater, (for the $3,000 rebate) or electrical resistance water heater (for the $500 rebate).
You do not have to be the PG&E account holder to qualify for the rebate. However, you must be the property owner. If the application is not under the PG&E account holder’s name, we will reach out to request additional documentation that proves you are the property owner and/or reside at the property.
Yes, rental properties qualify for the rebate as long as the rebate applicant is the property owner.
If you installed a HPWH between January 1, 2022 and September 30, 2022, you are eligible for our previous rebate amount of $1,000. Only installations completed on or after October 1, 2022 are eligible for our current rebate of $3,000.
Yes, we offer up to two heat pump water heater rebates per electric account; one per water heater replaced.
It depends. The electrical panel upgrade must take place within 6 months of the heat pump water heater or heat pump HVAC installation to qualify. This rebate is a bonus rebate, not a standalone rebate, and therefore cannot be applied for on its own. The rebate must be applied for at the same time as a heat pump water heater or heat pump HVAC rebate.
This rebate is a bonus rebate, not a standalone rebate, and therefore cannot be applied for on its own. The rebate must be applied for at the same time as a HPWH or heat pump HVAC rebate. If you are using a different contractor for your electrical panel upgrade and the HPWH contractor is the one applying for you, you should provide with them with these three things: 1) copy of permit for electrical work, 2) photo of the inside of the panel, and 3) invoice for your contractor/electrician for the panel upgrade. Your contractor will submit these documents for you along with the HPWH application.
If you are applying yourself, you can submit all the documents for the HPWH and electrical panel upgrade in that single application.
The program does not have an end date and is available until funding is depleted. Rebates are available on a first-come, first-served basis based on the application submittal date. It is likely for the rebates to continue through 2023 and future years, though the rebate levels are subject to change.
