Oregon water heater rebates and tax credits in 2026: what is actually available

What changed for 2026: the federal credit is gone

The Energy Efficient Home Improvement Credit, known by its tax code section as 25C, paid up to $2,000 a year toward a qualifying heat pump water heater. The IRS lists it for qualifying property placed in service from January 1, 2023 through the end of 2025. There is no version of it for 2026.

The test the IRS applies is when the unit was placed in service: installed and working, not bought or ordered. A heat pump water heater that was paid for in December 2025 but installed in January 2026 does not qualify.

This matters because a lot of cost guides you will find online were written while the credit still existed, and many still say a "30% federal tax credit" applies. Some carry a 2026 date in the title and the old credit in the body. Check the date on anything you read about water heater incentives, and ignore any figure that depends on the federal credit.

Everything below is what is still on offer to Oregon homeowners as of September 2026. Incentive programs change their amounts during the year, so confirm the current figure with the program before you buy.

Energy Trust of Oregon: the main incentive for most Oregon homes

Energy Trust of Oregon runs the efficiency incentives for customers of five Oregon utilities. Its incentives are open to homes served by Portland General Electric, Pacific Power, NW Natural, Cascade Natural Gas or Avista. If one of those names is on your bill, you are probably eligible. The heat pump water heater offer is Oregon only; Energy Trust's Washington program does not include it.

Heat pump water heater conditions. The unit must be rated Tier 3 or higher under the Northwest Energy Efficiency Alliance specification. It must replace a standard electric water heater in an existing home; the incentive is for retrofits, not new construction. For the $1,200 version the unit must be installed by a licensed contractor. For the $1,000 in-store discount there is a limit of one unit per customer and online purchases are excluded.

Gas tankless conditions. The unit must be ENERGY STAR qualified at the time of purchase and on Energy Trust's qualified products list. It must replace an existing gas storage tank, in a home with an existing half-inch or three-quarter-inch gas line that can serve the existing gas appliances plus the tankless unit. A gas line upgrade between the meter and the water heater is acceptable; an upgrade between the street and the meter disqualifies the project unless the utility paid for it.

The paperwork rules. For incentives you apply for after installation, the application and supporting documents must be submitted within 60 days of installation, with itemized contractor invoices marked paid in full. A contractor who is not enrolled with Energy Trust can still install qualifying equipment, but must hold a current Oregon Construction Contractors Board license. Energy Trust states that all incentives are subject to funding availability and may change.

Eugene: EWEB runs its own program

Eugene Water & Electric Board is Eugene's publicly owned utility, and it is not one of the five utilities Energy Trust serves, so its electric customers apply through EWEB instead.

EWEB pays $1,100 per heat pump water heater, and $2,200 for income-qualified customers in owner-occupied homes ($1,100 for income-qualified rentals). The unit must be Tier 3 or Tier 4. At the time of writing, EWEB applies the $1,100 at the point of sale through Jerry's Home Improvement Center and through General Pacific, so the discount comes off the price rather than arriving later as a check. There is one rebate per home.

EWEB also offers a zero-percent loan of up to $2,500 over 48 months. The rebate and the loan cannot normally be combined, except for income-qualified customers borrowing for costs above the rebate. For the income-qualified rebate, the new heat pump water heater must replace an existing electric water heater.

The same logic applies anywhere in Oregon served by a people's utility district, a municipal utility or an electric cooperative rather than PGE or Pacific Power: Energy Trust's electric incentives do not apply, and your own utility is the place to ask. Many of them run their own programs, and the amounts differ.

The state rebates that have not opened

Oregon has two federally funded rebate programs on paper: the Home Efficiency Rebates program (HOMES) and the Home Electrification and Appliance Rebates program (HEAR). The Oregon Department of Energy received more than $113 million from the 2022 Inflation Reduction Act to run them, with a focus on low- and moderate-income households.

As of September 2026 the department's own page says it plainly: no rebates are currently available, and a launch date will be set once the U.S. Department of Energy approves it. The department reports that the U.S. Department of Energy has suspended its approvals of launch requests from state rebate programs while it reviews its priorities.

The practical advice is simple. Do not delay a needed replacement waiting for these, and do not buy anything on the strength of a website that says they are available. If you want to know when they open, the Department of Energy runs an email list through homeenergyrebates.oregon.gov.

Which water heaters the incentives actually favour

The money in 2026 points strongly in one direction. A heat pump water heater replacing an electric tank attracts $1,000 to $1,200 from Energy Trust or $1,100 from EWEB. A gas tankless unit replacing a gas tank attracts $400. A standard tank, gas or electric, attracts nothing.

That does not make a heat pump water heater the right answer for every house. It pulls heat from the air around it, so it wants a garage or basement with real air volume rather than a small interior closet, and it cools that space slightly. In a cramped closet it will struggle, and no incentive fixes that. Our water heater repair and replacement page covers how to judge the fit.

Two rules catch people out. First, Energy Trust's heat pump incentive requires the new unit to replace a standard electric water heater. If you are switching from a gas tank to a heat pump, that offer does not apply as written, so ask Energy Trust before you count on it. Second, the gas tankless incentive requires the existing gas line to have the capacity. Gas supply is the most common and most expensive surprise in tankless conversions, and the sizing calculator shows how large a unit your household actually needs.

How to claim an incentive without losing it

1. Find your utility on your bill

   The electric utility decides the heat pump incentive; the gas utility matters for tankless. PGE, Pacific Power, NW Natural, Cascade Natural Gas or Avista means Energy Trust. EWEB, a PUD, a municipal utility or a co-op means asking that utility directly.

2. Confirm the current amount before you buy

   Amounts change during the year. Check Energy Trust's water heater page or your utility's rebate page on the day you decide, not a figure from an article, this one included.

3. Pick a model that is on the list

   Tier 3 or higher for heat pump units, ENERGY STAR and on the qualified products list for gas tankless. A model that is efficient but not listed does not qualify.

4. Buy it the way the incentive requires

   The $1,000 Energy Trust discount is in-store only. The $1,200 version comes through a contractor sourcing the unit from an eligible distributor. EWEB applies its rebate at participating sellers. Buying the right unit the wrong way can forfeit the incentive.

5. Get the installation permitted and inspected

   A replacement has to meet the code items Oregon requires at replacement, including seismic strapping and relief valve piping. Our water heater replacement cost guide lists them.

6. Keep the paperwork and file on time

   For incentives claimed after installation, such as the gas tankless incentive: the itemized invoice marked paid in full, and the application within 60 days of installation.

What the incentives do to the price you pay

A worked example makes the difference concrete. Today's Homeowner's cost guide (April 2025) puts the average installed price of a heat pump water heater at about $3,600. For an eligible Energy Trust customer with a contractor installation, the $1,200 incentive brings that to about $2,400. For an income-qualified EWEB customer in an owner-occupied home, $2,200 brings it to about $1,400.

Those are illustrations built from published averages, not a price for any particular house. Installed cost depends on access, electrical work, whether the old tank is in a tight closet, and what the code requires at your address. Our 2026 replacement cost guide goes through what moves the number.

If your current tank is still healthy, there is no incentive deadline forcing a decision this year. If it is eight years old or more, or showing any of the warning signs of a failing water heater, choosing the replacement now, while you can compare options and incentives calmly, is much cheaper than choosing it on the morning the tank leaks.
