Replacing a gas water heater with a heat pump model costs between $4,000 and $7,500 installed. That number stops a lot of people — until they find out how much of it comes back. Between your local utility rebate, a statewide instant discount, and a federal tax credit, you can recover $3,500 to $5,200 on a single project, sometimes more.
The money is there. The programs are just spread across four different sources, each with its own eligibility rules, deadlines, and paperwork. This guide breaks all of them down in one place, so you know exactly what you qualify for before the job starts.

Peninsula Clean Energy (PCE) — San Mateo County
PCE is a not-for-profit community choice electricity provider covering San Mateo County. Their rebate program has been running since 2021 and is funded until further notice on a first-come, first-served basis.
How the rebate works
The standard rebate is $2,500 when you replace a gas water heater with a heat pump model. If you replace an electric resistance water heater instead, the rebate drops to $500. Customers enrolled in CARE or FERA income assistance programs get an additional $1,000 on top — bringing the total to $3,500. In some cases, income-qualified customers may qualify for a no-cost installation through PCE’s Full-Service program.
There is also a $1,000 bonus rebate for electrical panel upgrades, and $500 for an advanced energy management device that helps avoid the need for a panel upgrade altogether. These are add-on rebates and cannot be claimed on their own — they only apply when claimed alongside the water heater rebate.
Who can apply
You need to be a PCE electric account customer and the property owner. Rental properties qualify. New construction, ADUs, and homes undergoing major structural remodels do not. You do not need to be a BayREN Participating Contractor or use one — since 2024, PCE accepts applications directly from customers.
Deadlines and process
The application goes in after installation, within 90 days. You will need an invoice showing the total installed cost, a city permit, and before/after photos of the equipment. PCE estimates 4–6 weeks from application to check.
PCE also offers a 0% interest loan of up to $10,000 with no credit check, which can cover the out-of-pocket cost before the rebate arrives.
Silicon Valley Clean Energy (SVCE) — Santa Clara County
SVCE serves 13 jurisdictions in Santa Clara County, including Sunnyvale, Mountain View, Los Altos, Milpitas, Campbell, Cupertino, and Saratoga. Their rebate program is called FutureFit Homes.
How the rebate works
The standard rebate for replacing a gas water heater is $2,000. Replacing an electric resistance water heater gets you $1,000. CARE/FERA customers receive an additional $1,000 on top of either amount.
Some cities have layered their own rebates on top of SVCE’s. Mountain View added a $2,000 city rebate for residents (with $1,000 more for income-qualified), though availability depends on city budget cycles — check directly with SVCE or the city before counting on it.
Add-on rebates include $1,000 for a panel upgrade and $500 per circuit (up to 4 circuits) for prewiring future electric appliances. Note: the prewiring rebate for a water heater circuit cannot be combined with the water heater appliance rebate in the same project.
One rule that catches people off guard
SVCE requires you to reserve your rebate before the installation starts. Skip this step and you lose the rebate — even if the installation is otherwise fully compliant. The only exception is emergency water heater replacements. SVCE offers a Full-Service Emergency Replacement program for those situations, which handles the rebate paperwork on your behalf.
Who can apply
SVCE electric account holders who own the property. Single-family homes, ADUs, mobile homes, and small multifamily buildings (4 units or fewer) all qualify. New construction does not.
Golden State Rebates — Statewide PG&E Customers
Golden State Rebates is a CPUC-funded statewide program administered by CLEAResult and supported by PG&E, SCE, and SDG&E. If you have a PG&E electric account — which covers most of San Mateo and Santa Clara County — you qualify.
How the rebate works
The rebate comes as a retail coupon applied at the point of purchase through a participating distributor, or as an instant discount when buying through a participating retailer. You do not get a check in the mail.
For gas-to-heat-pump replacements, the rebate amounts depend on tank size:
- $600 — 45 to 55 gallon HPWH replacing a 30–40 gallon gas tank
- $700 — over 55 up to 75 gallon HPWH replacing a 40–50 gallon gas tank
- $700 — 75 gallon and above HPWH replacing a 50–60 gallon gas tank
- $400 — 45 to 55 gallon HPWH replacing an electric resistance tank
All models must meet UEF 3.30 minimum and appear on the program’s Qualified Products List at time of purchase.
What to watch
The water heater must be installed within 60 days of purchase. The rebate is processed through the distributor — which means your contractor needs to buy the equipment through a participating distributor for the rebate to apply. Self-installation is permitted but working with a licensed contractor is strongly recommended by the program.
Golden State Rebates does not add a new income tier or additional bonus categories. Its strength is that it stacks cleanly on top of PCE, SVCE, and the tax credit with minimal extra paperwork.
IRS 25C Energy Efficient Home Improvement Credit
The federal 25C tax credit applies to heat pump water heaters installed in your primary residence. Unlike the utility rebates, you do not need to be in any specific utility territory — this one applies everywhere in the U.S.
How it works
The credit covers 30% of the cost of the equipment and installation, up to $2,000 per year for heat pump water heaters and heat pump HVAC systems combined. If you also upgrade your electrical panel as part of the same project, that adds up to $600 under a separate line item (the annual cap for panel upgrades is $600).
You claim it on your federal tax return for the year the equipment was placed in service. There is no income limit.
How it interacts with rebates
The tax credit is calculated on the cost after any rebates that were issued to you. So if you receive a $2,500 PCE rebate and a $700 Golden State discount before paying for the project, the 30% is applied to what you actually paid out of pocket, not the gross project cost.
This still adds up. On a $6,500 project: subtract $2,500 PCE + $700 Golden State = you paid $3,300. The 30% credit on $3,300 is $990, which comes back as a tax credit. Total recovered on a $6,500 project: $4,190.
One important detail
The $2,000 annual cap applies to heat pump water heaters and heat pump HVAC systems together. If you install both in the same tax year, the combined credit cannot exceed $2,000. If you want to maximize the credit, consider staggering the installations across two tax years.
How to Stack the Programs
All four incentives can be combined. The only limit is that the total of all rebates and credits cannot exceed the actual cost of the project.
Typical scenario — San Mateo County (PCE territory)
- PCE rebate: $2,500
- Golden State Rebates coupon: $700
- IRS 25C credit: ~$990 (30% of out-of-pocket cost after rebates)
- Total recovered: ~$4,190 on a $6,500 project
Income-qualified customers in PCE territory can add $1,000 more (CARE/FERA), bringing total recovery to $5,190 before the tax credit calculation.
Typical scenario — Santa Clara County (SVCE territory)
- SVCE rebate: $2,000
- Golden State Rebates coupon: $700
- IRS 25C credit: ~$1,140 (30% of out-of-pocket cost after rebates)
- Total recovered: ~$3,840 on a $6,500 project
If your city has an active supplemental rebate (Mountain View, Los Altos), the number goes up. Check with SVCE before scheduling the installation.
Ready to Get the Rebates?
Collecting these rebates is not complicated, but the order of steps matters — especially with SVCE’s pre-approval requirement and Golden State’s 60-day purchase-to-install window. A missed step means a missed rebate.
