Oregon Energy Trust water heater rebates are one of the most underutilized homeowner benefits in the Portland metro. If you're on NW Natural gas or Portland General Electric, you could have $400–$700 taken directly off your installation invoice — not a mail-in rebate, not a tax credit — money off right at the time of installation. Here's exactly how it works.

Quick Summary

Oregon Energy Trust (OET) offers up to $400 on qualifying gas tankless water heaters and up to $700 on heat pump water heaters. You must be a NW Natural, Cascade Natural Gas, Portland General Electric, or Pacific Power customer. Use a participating contractor (like PDX Water Heater Pros) and you'll see the savings on your invoice — no paperwork required on your end.

What Doesn't Qualify

Standard gas tank water heaters do not qualify for Oregon Energy Trust rebates. Standard electric tank water heaters do not qualify. Only high-efficiency units — condensing gas tankless (UEF ≥ 0.87) and heat pump water heaters (UEF ≥ 3.3) — are eligible. If you're replacing like-for-like with a standard tank, there is no rebate.

WHO QUALIFIES

Eligibility Factor Gas Tankless Rebate Heat Pump Rebate
NW Natural or Cascade Natural Gas customer Required Not required
Portland General Electric or Pacific Power customer Not required Required
Oregon service address Required Required
Homeowner or renter (paying utility bill) Either qualifies Either qualifies
Commercial property Does not qualify (residential program) Does not qualify
New construction Does not qualify Does not qualify

Most Portland homeowners are NW Natural customers and Portland General Electric customers — meaning they can potentially qualify for both programs depending on which unit type they choose. If you're uncertain about your utility provider, it's listed on your monthly bill.

WHICH WATER HEATERS QUALIFY

Qualifying Gas Tankless Models (UEF ≥ 0.87)

Virtually all major condensing gas tankless models meet the threshold. The units we install at PDX Water Heater Pros that qualify:

  • Navien NPE series — NPE-180A2, NPE-210A2, NPE-240A2 (UEF 0.97+)
  • Rinnai RU/RUR series — RU130iN, RU160iN, RUR199iN (UEF 0.93–0.96)
  • Noritz EZ series — EZ111, EZ181, EZ199 (UEF 0.93–0.95)
  • Bosch Greentherm C series — C 950, C 1050 (UEF 0.95+)

Non-condensing tankless models with UEF below 0.87 do not qualify. This mostly affects older or entry-level units. If you're buying specifically for the rebate, stick with condensing models.

Qualifying Heat Pump Water Heater Models (UEF ≥ 3.3)

  • Rheem ProTerra series — 50-gallon and 80-gallon models (UEF 3.7–4.0)
  • A.O. Smith Voltex series — 50-gallon and 66-gallon (UEF 3.69+)
  • Bradford White AeroTherm — 50 and 80 gallon (UEF 3.42)

WHAT THE REBATE MEANS FOR YOUR ACTUAL BILL

EXAMPLE: GAS TANKLESS INSTALLATION WITH OET REBATE
Navien NPE-240A2 installed (labor, permit, disposal) $2,650
Oregon Energy Trust rebate (gas tankless, NW Natural) − $400
Annual energy savings vs. standard tank (est.) − $150/yr
Effective net cost after rebate $2,250

That $2,250 effective cost puts a premium condensing tankless unit at roughly $300–$500 more than a quality 50-gallon gas tank replacement — before accounting for the ~$1,500–$2,000 in energy savings over a decade and the fact that the tankless unit will last twice as long.

HOW TO CLAIM YOUR OREGON ENERGY TRUST REBATE

There are two ways to claim the Oregon Energy Trust water heater rebate:

  1. 1
    Use a Participating Contractor (Easiest)
    The simplest path. PDX Water Heater Pros is a registered OET participating contractor. We apply the rebate directly to your installation invoice — you pay the net price and never file paperwork. Call us at (971) 293-4200 and mention you want to apply the Oregon Energy Trust rebate when scheduling.
  2. 2
    Self-Submit (If Contractor Isn't Participating)
    If you've already had a unit installed by a non-participating contractor, you can still claim the rebate yourself. Submit a rebate application at energytrust.org within 90 days of installation. You'll need: your invoice showing the installed unit model number, proof of Oregon utility service, and a completed rebate form. Expect 6–8 weeks for processing.
Don't Miss the 90-Day Window

Oregon Energy Trust rebate applications must be submitted within 90 days of installation. If you had a qualifying unit installed and didn't claim the rebate, you still have time — check your installation date and submit immediately if you're inside the window.

COMBINING OET WITH FEDERAL TAX CREDITS

The Oregon Energy Trust rebate can be combined with the federal Inflation Reduction Act (IRA) energy efficiency tax credits. In 2026, the IRA offers a 30% tax credit on heat pump water heaters, up to $600, for homeowners. Stack that with the $700 OET rebate and you're looking at potentially $1,300 in combined savings on a heat pump installation.

For tankless water heater installation with Oregon Energy Trust rebate applied, call us at (971) 293-4200 and we'll handle the rebate paperwork completely. If you want to confirm your utility eligibility before scheduling, we'll walk you through it on the phone.
