Eligible models:
- ENERGY STAR certified electric heat pump water heaters (UEF ≥ 2.75)

- Condensing gas models (limited rebates, $100–$200)
Rebate amounts (2026) per Rocky Mountain Power official Wattsmart rebate program:

Pro tip: Some contractors submit rebates on your behalf. Verify this before signing the contract. If you’re buying the heater yourself (DIY or through a big-box store), you’ll need to apply manually—more complex but possible.

Federal Energy Tax Credit (Biggest 2026 Opportunity)
Coverage: All U.S. homeowners, including Utah. Available through December 31, 2032 (recently extended).
What qualifies:
You can claim a $2,000 federal tax credit if you install a qualified electric heat pump water heater (HPWH).
Requirements:
- Must be a primary residence (not rental property, second home, or investment)
- Equipment must be ENERGY STAR certified
- Installed by a licensed contractor (DIY installation doesn’t qualify)
- CRI/AHRI certified for your region (check product specs)
Income limits apply (see table below).
Income limits (2026):
| Household Size | Income Cap |
|---|---|
| 1 person | $87,000 |
| 2 people | $112,000 |
| 3 people | $137,000 |
| 4 people | $162,000 |
| 5+ people | $187,000 |
If your income exceeds these limits, you still get the credit (no income limit through Dec 31, 2032), but the rebate is 30% of cost instead of $2,000 flat. This typically results in $600–$1,000 credit for most homeowners.
How to claim:
- Install a qualifying ENERGY STAR heat pump water heater before Dec 31, 2026.
- Contractor installs and provides certification of installation.
- On your 2026 tax return (filed in 2027), claim Form 5695 (Residential Energy Credits).
- IRS processes the credit; you receive it as refund or tax deduction.
Best qualifying models (2026):
| Brand | Model | Price | Credit | Net Cost |
|---|---|---|---|---|
| Rheem | Proterra 80 gal | $2,400 | $2,000 | $400 |
| AO Smith | HPWH 75 gal | $2,200 | $2,000 | $200 |
| Navien | H-Select Hybrid | $2,800 | $2,000 | $800 |
Pro tip: Stack this with state rebates. Buy Rheem Proterra ($2,400), claim:
- Rocky Mountain Power rebate: -$550
- Federal tax credit: -$2,000
Net cost: -$150 (you’re actually ahead).
But wait—can you claim both? Yes. Federal tax credit and state rebates are stackable. You claim the state rebate first (reduces your out-of-pocket), then claim the federal credit on the full purchase price.

Utah State Energy Office Programs
Utah also runs state-level rebates through the Division of Energy & Mineral Resources.
Eligible heaters:
- High-efficiency tankless (natural gas or propane)
- Emerging technologies (under-sink solar, hybrid systems)
Amount: Typically $200–$300 per unit.
How to claim: Contact the Utah State Energy Office directly to confirm current programs.
Why so quiet? State funding is limited and varies yearly. Some years programs are fully funded; other years they’re on waitlists.
