Seattle Water Heater Rebates 2026: City Light, PSE, and What the Tax Credit Expiry Means for You
Get the real facts on 2026 water heater rebates in Seattle. City Light offers $750, PSE offers $1,000–$1,100, and the WA HEAR program helps income-qualified buyers. Plus: the federal tax credit is gone — here's the truth.
Let's get this out of the way first: if you've seen articles saying you can claim a $600 federal tax credit on a water heater replacement in 2026, that information is out of date. The credit was eliminated at the end of 2025. We'll cover exactly what happened.
The good news? The state and utility rebates are real; they're funded, and for some homeowners they stack. Here's everything you actually need to know.
The Quick Summary
First: City Light or PSE?
This question determines everything else. Seattle City Light and Puget Sound Energy (PSE) offer separate rebates — you can only access the one for your utility, and they don't overlap.
- Seattle City Light serves: The City of Seattle — West Seattle, Capitol Hill, Ballard, Rainier Valley, Fremont, Queen Anne, and the rest of the city proper.
- PSE serves: Bellevue, Kirkland, Renton, Mercer Island, Redmond, and most of the Eastside suburbs.
If you're not sure which utility you're on, check your electric bill or look up your address on each utility's website. Getting this wrong is the most common reason people apply for the wrong rebate and miss out.
Seattle City Light: $750 Back on a Heat Pump Water Heater
City Light's rebate is $750 for a qualifying heat pump water heater—also called a hybrid electric water heater. Standard electric resistance tanks don't qualify.
The unit needs to be ENERGY STAR Tier 3 or Tier 4. Most major brands have qualifying models: Rheem ProTerra, AO Smith Voltex, Bradford White AeroTherm, and GE Appliances hybrids all have Tier 3 or Tier 4 options.
Three ways to claim it
Path 1: Contractor discount. Your plumber purchases the water heater through a participating distributor and passes the $750 savings directly on your invoice. No paperwork on your end. Not every plumber is set up for this path — ask before you book.
Path 2: In-store coupon. Download an instant digital coupon from the City Light website and use it at a participating Home Depot or Lowe's in the Puget Sound area. You handle installation separately.
Path 3: Post-purchase rebate form. Bought from another supplier, or your contractor didn't go the distributor route? Submit an online rebate form with your retail invoice within 93 days of purchase. DIY installation qualifies for this path.
One thing to know: the program runs through December 31, 2026 — but only while funding lasts. "While funds last" is real language. Fall is when water heater replacements peak. Don't assume the rebate will still be there if you wait until December.
Puget Sound Energy: $1,000 Standard, $1,100 for Income-Qualified Customers
PSE's rebate is larger, but the application window is much tighter.
Standard rebate: $1,000
Requirements:
- You must be a PSE electric customer
- The water heater must be a qualifying Tier 3 or Tier 4 heat pump model (check PSE's qualified product list)
- Installed in an existing single-family home — new construction doesn't qualify
- Installed on or after January 1, 2026
Efficiency Boost: $1,100
Same equipment requirements, but for income-qualified customers. PSE uses county-specific income tables based on gross monthly household income and household size. PSE estimates that about half its customers may qualify—it's worth checking even if you don't think of yourself as income-qualified. Apply at pse.com/boost.
The deadline that trips people up
You have 30 days from installation to submit your application. Not 30 days from purchase — 30 days from the date the work is done. Miss this window, and you're out of luck.
If your plumber is handling the rebate paperwork, confirm they'll actually submit it. If you're doing it yourself, set a reminder in your calendar the day the job is done.
Three ways to apply: use an in-store coupon at participating retailers, work with a Trade Ally contractor who can provide the discount instantly, or submit PSE's online post-purchase rebate form.
The WA HEAR Program: Additional Help for Qualifying Households
Washington State's Home Electrification and Appliance Rebates (HEAR) program offers additional rebates on top of the utility programs for income-qualified households.
- Eligibility: Households at or below 150% of King County's Area Median Income (AMI). Both lower-income households (under 80% AMI) and moderate-income households (80–150% AMI) may qualify, with different benefit levels.
- Amount: Local administrators set rebate amounts —not the state directly. The City of Seattle received $1.6 million in HEAR funding for this purpose. Contact your local administrator to confirm current amounts. Don't rely on dollar figures you've seen online; they may reflect a different program or a different administrator's rate.
- How to apply: Through your local administrator. Find yours at commerce.wa.gov/energy-incentives/hear.
- The urgency: This is first-come, first-served. The funding is real, and the program is open — but it won't last indefinitely. If you think you might qualify, check sooner rather than later.
The Federal 25C Credit: What Happened
For years, Section 25C of the tax code offered a 30% credit (up to $2,000 in a shared category bucket, with water heaters specifically limited to $600) on qualifying heat pump water heaters. The Inflation Reduction Act had extended this through 2032. Then, on July 4, 2025, the One Big Beautiful Bill Act was signed into law. It terminated the Section 25C credit for any property placed in service after December 31, 2025.
What this means for 2026 installs: There is no federal tax credit for water heaters installed in 2026. Zero. Don't let a contractor or a blog post written in 2024 talk you into expecting a federal credit.
If you replaced your water heater in 2025: You can still claim the credit on your 2025 tax return. Consult your tax preparer and look for Form 5695.
Many local plumber websites, and even some national content sites, still show the 2032 credit date. That's outdated. The OBBBA changed everything.
Can You Stack These Rebates?
Yes — within limits.
A Seattle City Light customer who also qualifies for the WA HEAR program can stack both rebates. The combined savings depend on the HEAR administrator's current amounts for your household income tier.
A PSE customer can stack the $1,000/$1,100 PSE rebate with the WA HEAR program for additional savings.
City Light and PSE rebates cannot be combined — you access the one that matches your utility. But either one can stack with HEAR if you're income-qualified.
What the Equipment Needs to Qualify
Heat pump water heaters aren't just regular tanks with a different sticker. The installation has real requirements:
- Space: The unit needs at least 700–1,000 cubic feet of surrounding air space — roughly a 10x10 room. The heat pump pulls warmth from the surrounding air. A small closet with a sealed door won't cut it.
- Electrical: Most HPWHs require a dedicated 240V, 30-amp circuit. If you're replacing a standard electric tank, you likely have one. If you're switching from gas, you'll need an electrician to add the circuit first.
- Ambient temperature: The surrounding space needs to stay above approximately 40°F year-round. Most Seattle homes are fine. An uninsulated detached garage in January is borderline.
- Condensate drain: The dehumidification process produces condensation. You need a floor drain, condensate pump, or gravity drain path nearby.
Knowing this before the job is scheduled saves everyone time. A good plumber checks these things at the consultation — not after the unit is already delivered.
Questions to Ask Before You Book
Before calling a plumber about a heat pump water heater replacement, have these ready:
- Do you purchase through a participating City Light or PSE distributor?
- Will you submit the rebate paperwork on my behalf?
- Which Tier 3 or Tier 4 models do you typically install?
- Do you check the installation space requirements before the job?
- What does the total quote include — electrical work, permit, removal of the old unit?
A plumber who can't answer these questions is going to leave you doing the paperwork chase after the job is done.
