California water heater rebates in San Diego (2026)
What San Diego homeowners can still get for a heat pump water heater in 2026: Golden State Rebates of $400 to $700, plus why the federal 25C credit ended.
The short answer
- Golden State Rebates gives San Diego homeowners $400 to $700 instant off a qualifying heat pump water heater in 2026.
- The federal 25C tax credit (30% up to $2,000) expired December 31, 2025, so a 2026 install no longer qualifies.
- TECH Clean California rebates of $2,100 to $5,700 are fully reserved statewide as of February 2026, with new requests waitlisted.
- Only ENERGY STAR heat pump (heat pump) water heaters qualify for these incentives, not standard gas or electric tanks.
- Rebate amounts change often, so confirm the current figure on the official program page before you buy.
San Diego homeowners can still get $400 to $700 instant off a qualifying heat pump water heater in 2026 through Golden State Rebates, the program SDG&E directs customers to. The bigger news is what changed: the federal 25C tax credit (30% up to $2,000) expired December 31, 2025, and TECH Clean California rebates are fully reserved statewide. So the playing field is smaller than it was a year ago, but real money is still on the table.
Here’s the honest 2026 picture, with what’s active, what’s gone, and what equipment actually qualifies.
What’s still active in 2026: Golden State Rebates
Golden State Rebates is the statewide instant-rebate program that SDG&E customers in San Diego use. It’s the most accessible incentive right now because it comes as an instant coupon, not a tax filing or an application you wait on.
For a heat pump water heater, the 2026 amounts are $400 for a 45 to 55 gallon unit replacing an electric tank, $600 for a 45 to 55 gallon unit replacing a gas tank, and $700 for a unit over 55 gallons replacing a gas tank. You redeem it as an in-store coupon at a participating retailer or through an approved distributor. The unit has to be on the program’s Qualified Products list at the time of purchase.
Rebate amounts and qualified models change, so confirm the current figure at goldenstaterebates.com and check SDG&E’s own rebate page before you buy. SDG&E is San Diego’s gas and electric utility, so its programs and the statewide ones overlap here.
What’s gone: the federal 25C tax credit
The federal 25C Energy Efficient Home Improvement Credit gave homeowners 30% of project cost, up to $2,000 a year, for a qualifying ENERGY STAR heat pump water heater. It expired on December 31, 2025.
That means a heat pump water heater installed in 2026 no longer earns this credit. The one exception: if your unit was installed and placed in service on or before December 31, 2025, you can still claim it on your 2025 tax return filed during the 2026 tax season. If a salesperson tells you a 2026 install still gets the $2,000 federal credit, that’s outdated. Confirm any federal credit at irs.gov or energystar.gov before you count on it.
TECH Clean California: real money, but waitlisted
TECH Clean California ran the largest heat pump water heater rebates in the state. Market-rate Southern California incentives reached about $4,300, and income-qualified equity incentives reached about $5,700.
The catch in 2026: the program is no longer accepting new heat pump water heater reservations, and HEEHRA single-family rebates are fully reserved statewide as of February 24, 2026. New requests go on a waitlist, and any install has to happen after approval, not before. It’s worth getting on the list if you qualify, but don’t plan your purchase around money you can’t reserve yet.

What qualifies, and the real net cost
Every active heat pump incentive rewards one thing: an ENERGY STAR heat pump water heater. A heat pump water heater pulls heat from the air to warm the water, so it uses far less electricity than a standard electric tank. Standard gas tanks and gas tankless units don’t earn these rebates, because the programs are built to push electric heat pump technology.
On cost, a heat pump water heater usually runs $2,500 to $4,500 installed in San Diego before incentives, higher than a standard tank because of the unit price and sometimes an electrical circuit. A standard 40 to 50 gallon tank runs $1,500 to $2,500 installed here, and a full tankless conversion runs $4,000 to $6,500. For the full breakdown, see our water heater replacement cost in San Diego guide. A $400 to $700 Golden State Rebate narrows the gap between a heat pump unit and a standard tank without erasing it.
One more San Diego detail: any water heater swap needs a permit. Read our water heater permit in San Diego post so a pulled permit doesn’t catch you off guard, and use a licensed plumber so the install passes inspection.
Where California is heading
California is steering homeowners toward electric heat pump water heaters on purpose. CARB adopted a goal for zero-NOx (zero-emission) space and water heater sales by 2030, which over time would limit how many new gas-fired units manufacturers can sell in the state. Space and water heating accounts for nearly 90 percent of building-related greenhouse gas emissions in California, which is why the policy points this direction.
This is policy direction, not a current ban. No rule forces you to remove a working gas water heater, and the statewide standard isn’t final yet. If you’re weighing your options, our tankless vs. tank water heater in San Diego comparison walks through the tradeoffs beyond rebates.
Frequently asked questions
What water heater rebates can San Diego homeowners get in 2026?
In 2026, the main active rebate is Golden State Rebates, which gives $400 to $700 instant off a qualifying heat pump water heater. SDG&E points customers to this statewide program. The larger TECH Clean California rebates are fully reserved and waitlisted as of February 2026.
Did the federal heat pump water heater tax credit go away?
Yes, for new installs. The 25C Energy Efficient Home Improvement Credit, worth 30% of cost up to $2,000, expired December 31, 2025. If your heat pump water heater was installed and placed in service on or before that date, you can still claim it on your 2025 return filed in 2026.
How much is the Golden State Rebates heat pump water heater rebate?
Golden State Rebates offers $400 for a 45 to 55 gallon unit replacing an electric tank, $600 for a 45 to 55 gallon unit replacing a gas tank, and $700 for units over 55 gallons replacing a gas tank. It comes as an instant in-store coupon or a participating distributor purchase.
Is TECH Clean California still accepting applications?
No. As of February 24, 2026, TECH Clean California is no longer accepting heat pump water heater reservations, and HEEHRA single-family rebates are fully reserved statewide. New requests go on a waitlist, and installation has to happen after approval.
What does a heat pump water heater cost after rebates in San Diego?
A heat pump water heater runs higher than a standard tank up front, often $2,500 to $4,500 installed before incentives. A $400 to $700 Golden State Rebate trims that. Compare it to the $1,500 to $2,500 a standard tank costs in San Diego in 2026.
Is California banning gas water heaters?
Not yet, and there is no rule forcing you to rip out a working gas unit. CARB adopted a goal for zero-NOx (zero-emission) space and water heater sales by 2030, which would limit new gas units sold over time. Existing equipment is unaffected, and the statewide rule is not final.
Do tankless water heaters qualify for these rebates?
Gas tankless units do not qualify for the heat pump incentives, since those reward electric heat pump technology. A heat pump water heater is the unit that earns the Golden State Rebate. Tankless still saves space and runs efficiently, just without the current rebate.
