Water Heater Rebates: Where the Money Is in 2026
Water heating is the second-biggest energy load in most American homes — and the appliance people think about least until the shower runs cold. Utilities know both things, which is why water-heater rebates are among the most common programs in the country and among the least claimed. The money splits three ways in 2026: modest rebates for efficient like-for-like replacements, bigger checks for heat pump water heaters, and the biggest of all for fuel conversions — swapping an electric tank for gas tankless, or a standard tank for a hybrid. Your state and utility decide which doors are open.
The 2026 landscape in three layers
Every water-heater project gets its answer from three separate places, and they don't coordinate:
- Federal tax credits — gone. The 25C and 25D credits stopped applying to equipment placed in service after December 31, 2025. A water heater installed in 2026 earns no federal residential credit, whatever a sales flyer says.
- State programs — a mixed map. Some state-run rebate programs are open, some paused mid-year when funds ran out, and some never launched. Each of our state guides reports its own current status.
- Utility programs — where most of the real money lives. Gas utilities pay for efficient gas equipment, electric utilities for heat pump models, and territory decides eligibility down to the street. These budgets are annual and first-come, first-served.
What the programs actually pay — real examples from our guides
Numbers we've verified on the utilities' own pages (each links to the full guide):
- Oklahoma Natural Gas pays $1,100 for converting an electric water heater to gas tankless — and $850 for electric-to-gas tank swaps → full guide
- Atmos Energy (Mid-Tex/DFW) pays up to $300 on high-efficiency tankless and $100–$200 on efficient tanks → full guide
- Austin Energy pays $1,000 on ENERGY STAR heat pump water heaters → full guide
- Georgia Power pays up to $800 on heat pump water heaters → full guide
- Atlanta Gas Light pays $500 on tank-to-tankless conversions → full guide
- PSO (Oklahoma) pays up to $750 on ENERGY STAR heat pump water heaters → full guide
The pattern across all of them: the rebate grows with the efficiency jump. A slightly better tank earns $100; changing the technology earns four figures.
The decimal that decides everything: UEF
Water-heater rebates are gated by Uniform Energy Factor — and the thresholds are exact. ONG pays $1,100 on a tankless conversion at 0.80 UEF and nothing at 0.79. Atmos pays $200 at 0.87 and $300 at 0.95. The model number on the spec sheet, verified against its AHRI certificate, decides which side of the line you're on — not the brand, not the price, not what the installer remembers. Buying first and checking after is how homeowners end up two hundredths of a point short of a four-figure rebate.
Tank, tankless, or heat pump — the honest comparison
A standard tank keeps 40–50 gallons hot around the clock whether anyone showers or not. It's the cheapest to install and the most expensive to run, and most programs pay it little or nothing.
Tankless heats water only when a tap opens: no standby loss, endless hot water, a footprint the size of a suitcase, and a lifespan that routinely beats tanks by a decade. Gas utilities fund these hardest — especially conversions off electric tanks, where the grid relief is largest.
Heat pump (hybrid) water heaters move heat instead of generating it, using a fraction of the electricity of a resistance tank. Electric utilities fund these hardest — $750 to $1,000 checks are common — with the practical caveats that they need space, condensate drainage, and tolerate cool garages differently by climate.
Which one wins depends on your fuel, your utility's programs, and the house itself — which is exactly what the ZIP check sorts out.
Before you buy — the four checks that protect the rebate
- Territory — the utility that delivers your gas or electricity runs the program, not the company on your bill. Conversions can involve both utilities at once.
- The spec — UEF threshold and ENERGY STAR status confirmed from the AHRI certificate for the exact model.
- The clock — filing windows range from 45 days (Atlanta Gas Light) to 180 (ONG); some programs require applying before installation, and every budget can run out mid-year.
- The paperwork — receipt, contractor invoice with model and serial numbers, and the AHRI certificate are the standard trio. Miss one and approved becomes denied.
We run these four checks before you spend anything, then connect you with a licensed contractor whose paperwork actually gets filed inside the window.

Water heater rebate questions
Are water-heater rebates available everywhere?
No — coverage follows utility territory and program budgets. We track all 50 states; 41 of our state guides currently carry published water-heater measures, and the administering program always makes the final call.
Which type earns the biggest rebate?
Fuel conversions, almost everywhere: electric-tank-to-gas-tankless swaps and standard-to-heat-pump upgrades earn several times what a like-for-like replacement gets.
Is there still a federal tax credit?
Not for 2026 installations — 25C and 25D ended for property placed in service after December 31, 2025. State and utility programs are unaffected.
Can I count on an advertised amount before buying?
Treat every published number as a summary, not a guarantee. Amounts, budgets and rules are confirmed at application time by the program — which is why the spec-and-paperwork check happens before the purchase, not after.
My water heater still works — should I wait for it to fail?
Failure day is the worst day to shop: no time to verify specs, compare quotes, or file pre-approvals. A working heater past its warranty age is the ideal rebate candidate — you choose the timing.
