Water Heater Rebates in 2026
The federal credit has ended. A lot of published advice has not caught up.
Heat & Tap earns a commission on qualifying purchases made through the Amazon links on this page, at no extra cost to you. Commission does not decide what we recommend or how we rank it. Full disclosure.
The Section 25C Energy Efficient Home Improvement Credit expired on December 31, 2025, terminated by the One Big Beautiful Bill Act (P.L. 119-21) for equipment placed in service after that date. Its cap had been $2,000 a year for a heat pump water heater. What remains is state HEAR programs and utility rebates, which vary completely by zip code.
That is the bad news, stated first. The better news is that the federal credit was never the largest incentive for most households — utility rebates frequently are, and they are still there.
What the 25C credit was
| Item | Position |
|---|---|
| Status | Expired December 31, 2025 |
| Terminated by | One Big Beautiful Bill Act, P.L. 119-21 |
| Applies to | Equipment placed in service after that date does not qualify |
| Cap for a heat pump water heater | $2,000 per year |
| Overall annual cap | $3,200 |
If your equipment was placed in service on or before December 31, 2025, that is a question for your tax preparer rather than for us. For anything installed in 2026, the credit is not available.
What still exists
State HEAR programs
The Home Electrification and Appliance Rebate programs are funded federally but administered state by state, each with its own launch timing, eligibility rules and income thresholds. Heat pump water heaters are a covered measure in these programs.
Because the rules and amounts are set per state, we are not going to print a figure. Your state energy office is the authoritative source, and it is the first place to look.
Utility rebates
Frequently the most accessible and sometimes the largest incentive available, and the one households overlook most. Electric utilities have a direct interest in heat pump water heaters because they shift and reduce load, and many run standing rebate programs with straightforward paperwork.
Several utilities also run demand-response programs that pay you to let them shift when your water heater runs. Rheem's ProTerra models include an EcoPort CTA-2045 port specifically to connect to those programs, and a slow-recovery tank that heats overnight is exactly the load a utility wants to control. 120 V plug-in heat pumps.
Other possibilities
- State tax credits, which exist in some states independently of the federal position.
- Municipal and water district programs, occasionally, particularly where water conservation is a local priority.
- Manufacturer rebates, which come and go and are worth a search before you buy.
- Contractor promotions, especially at the end of a quarter.
How to check yours properly
Start with your electric utility
Search the utility's own site for "heat pump water heater rebate". This is the most likely source of real money and the easiest paperwork. Note any requirement to apply BEFORE installation.
Check your state energy office for HEAR
Programs launched at different times by state and have their own income eligibility rules. The state energy office page is authoritative; third-party summaries go stale.
Check the DSIRE database
The Database of State Incentives for Renewables and Efficiency is the standard aggregator for state and local programs. Treat it as a starting point and verify against the program's own page.
Confirm the specific model qualifies
Programs usually require ENERGY STAR certification and often a minimum UEF. The units in our registry publish their UEF: 3.42 to 4.02 on the heat pumps.
Read the paperwork requirements BEFORE you buy
This is where people lose rebates. Some require pre-approval, a licensed installer, a specific AHRI certificate number, or an itemized invoice. None of that can be assembled retroactively.
Keep everything
The itemized invoice, the model and serial number, the AHRI or ENERGY STAR documentation, and the installer's license number.
Procedure: Check water heater rebates for your address
Units that typically qualify
Pick 1 — Most heat pump installs
Rheem ProTerra 50 gal hybrid
The heat pump water heater to start with: a 3.88 UEF, a 67-gallon first-hour rating, and a 37°F lower operating limit that is the widest ambient range in its class — which is the specification that decides whether it works in a cold garage.
| Capacity | 50 gallons |
|---|---|
| Efficiency | 3.88 UEF; up to 4.07 UEF advertised on 30 A models |
| First-hour rating | 67 gallons |
| Recovery | 27 gallons per hour |
| Heat pump capacity | 4,200 BTU/h |
| Backup element | 5,000 W |
| Voltage | 208 - 240 V |
| Ambient operating range | 37 - 145°F |
| Cold-climate rating | Meets Northern Climate Specification Tier 4 |
| Leak protection | Integrated detection with factory-fitted auto shutoff; leaks limited to no more than 20 oz |
| Warranty | 10-year limited |
What is good
- A 37°F lower limit means the compressor keeps running in an unheated garage through most of a northern winter
- 3.88 UEF is roughly four times a resistance tank, so the running cost difference is not marginal
- 67-gallon first-hour rating is better than most 50-gallon resistance tanks
- EcoNet control lets you force high-demand mode before guests arrive instead of discovering the limit
What is not
- It is a refrigeration appliance in your house: there is a compressor, a fan and a condensate drain
- Needs roughly 700 cubic feet of air, or louvered doors, in a closet
- It cools and dehumidifies the space it stands in, which is a gift in a Houston garage and a problem in a Minnesota basement
Skip it if: Skip it if the only place it can go is a finished, heated room you occupy. It will steal heat from that room in winter — your furnace then pays for the hot water, and the efficiency you bought disappears.

Pick 2 — Highest published heat pump efficiency
A. O. Smith Voltex AL, 66 gal
The efficiency leader on this page at 4.02 UEF, in the capacity that suits a five- or six-person household, with a heavy-duty anode rated to protect the tank for 10 years.
| Capacity | 66 gallons |
|---|---|
| Efficiency | 4.02 UEF |
| Anode | Heavy-duty, rated to protect the tank for 10 years |
| Warranty | 10-year limited |
| Certification | ENERGY STAR certified |
What is good
- 4.02 UEF is the highest figure of any unit in this registry
- 66 gallons removes the recovery anxiety that a 50-gallon heat pump creates in a big household
- The 10-year anode is a real durability claim, not a marketing one
- ENERGY STAR certification keeps it inside most utility rebate lists
What is not
- 66 gallons is a tall, wide cabinet — measure the space before you order
- Sold mainly through wholesale, so availability is slower than big-box
- Published first-hour rating is not listed for the AL model; the Voltex MAX at the same capacity is rated at 83 gallons
Skip it if: Skip it if your install space is a closet. A 66-gallon heat pump needs air volume to work, and starving a heat pump water heater of air is how you end up running on the backup element and paying resistance rates for a premium appliance.

Pick 3 — No 240 V circuit available
Rheem ProTerra 120 V plug-in, 50 gal
The one heat pump water heater that does not need an electrician: it runs on a dedicated 120 V 15 A circuit, which makes it the only realistic efficiency upgrade in a condo or a house with a full panel.
| Capacity | 50 gallons |
|---|---|
| Voltage | 120 V |
| Power | 1.8 kW |
| Circuit | Dedicated 120 V 15 A |
| Efficiency | 3.0 UEF on a dedicated circuit; up to 3.5 UEF on the shared-circuit model |
| Ambient operating range | 37 - 145°F |
| Cold-climate rating | Designed to meet NEEA Northern Climate Specification Tier 2 |
| Utility programs | Built-in EcoPort CTA-2045 port |
What is good
- A standard 120 V circuit removes the panel upgrade that kills most heat pump retrofits
- Still roughly three times as efficient as a resistance tank
- CTA-2045 port makes it eligible for utility demand-response payments where those exist
- Same 37°F lower operating limit as the 240 V models
What is not
- 1.8 kW means slow recovery — this is a tank you let work overnight, not one you push
- No big resistance element to bail you out during a surge in demand
- A dedicated circuit is still a circuit: a shared-outlet install is a different model number
Skip it if: Skip it if your household regularly empties the tank — a big family, or two showers plus a dishwasher back to back. With 1.8 kW of input and no large backup element, recovery is the whole constraint.

The eligibility details that catch people
- Pre-approval. Some programs require you to apply before the work is done. Installing first disqualifies you, permanently.
- Licensed installer required. DIY installation disqualifies many rebates regardless of the quality of the work.
- Minimum UEF thresholds. A resistance tank will not qualify for a heat pump rebate, and some programs set a UEF floor that the entry-level heat pump units do not clear.
- Fuel switching rules. Some programs pay more for replacing a resistance tank than for replacing a gas one, and some exclude gas-to-electric conversions entirely.
- Income verification on HEAR programs, which have tiers.
- Program funds running out. These are budgeted programs. Applying early in a program year matters.
What goes in with it
A water heater is a system, not a box. These are the parts that go in with it, and the ones people discover they need halfway through the job.
- Drain pan
A heat pump water heater makes condensate continuously, so this one is not optional.
- Leak detector
A condensate line that blocks will overflow long before you notice it.
- Expansion tank
Same closed-system rule as any other storage tank.
