What water heater rebates pay in Seattle
We read Seattle City Light's heating and cooling page and the State Department of Commerce page on October 6, 2026. The City Light rebate is for the electric side of your home, so it fits households with an electric tank now.
Seattle City Light rebate, contractor route
Your contractor installs a qualifying heat pump water heater and the $750 comes off the bill or goes to you through the contractor. The unit must be ENERGY STAR rated and a Tier 3 or Tier 4 model on the qualified list.
Instant coupon at The Home Depot or Lowe's
A discount at the store on a qualifying unit. Units bought with the coupon cannot also use the online rebate form.
Online rebate for do-it-yourself installs
If you buy from another seller and install it yourself, you can apply to City Light for $750 on an online form.
State home electrification rebates
Heat pump water heaters are on the state's list of equipment for households at or below 150 percent of area median income. The City of Seattle received $1,616,516 to give out. The state page lists no per-household amount.
Working it out
If a Seattle household pays $2,400 for a qualifying heat pump water heater installed by a contractor, the $750 rebate brings the cost to $1,650. The $2,400 is only an example, not a quote. Ask for local bids, because installation work such as new wiring or moving the tank can change the total.
Why the electric tank matters here
The US Census Bureau's American Community Survey (2020 to 2024) says about 61 percent of Seattle homes use electricity as their main heat. The survey does not count water heaters, but a home that heats with electricity often also has an electric tank. If you have one, it is probably the biggest single use of power in the house after heating. A heat pump water heater moves heat from the air around it into the water, so it uses less electricity for the same amount of hot water. The City Light page does not give an energy saving number, so we do not quote one.
Seattle also has more renters than owners, about 56 percent of households, and 63 percent of homes are not detached houses. In an apartment or condo the water heater may belong to the building. In that case the owner or the homeowners association decides, and City Light's page for single-family homes may not fit.
Which of the three routes to pick
The contractor route fits a household that wants someone else to size the unit, haul away the old tank and handle permits. The store coupon is quick if you already have an installer and you shop at The Home Depot or Lowe's. The online rebate is for people who buy elsewhere and install it themselves. You cannot stack the coupon with the online rebate, so pick one before you buy. Check that the exact model number appears on City Light's list of Tier 3 and Tier 4 models, because a model that looks the same but is a different number may not qualify.
Space and size questions to ask
A heat pump water heater needs room to breathe, and it works best in a space that does not get too small or too cold. City Light links a guide on right-sizing the unit through its partner, Hot Water Solutions Northwest. Ask your contractor how many people live in the home and whether the tank will fit through the doorway or down the stairs. A good bid names the model, the installation work, the permit and the disposal of the old tank, and shows the $750 as a separate line.
How to claim a Seattle water heater rebate
- Look up your model on the City Light list of Tier 3 and Tier 4 models before you buy.
- Choose the contractor route, the store coupon or the online rebate.
- If you use a contractor, ask them to show the $750 on the bid.
- If you install it yourself, buy the unit and fill out the City Light online rebate form with your receipt.
- Keep the receipt, the model number and the install date.
