- What does a heat pump water heater cost installed?
- $2,800 to $8,000, with a typical installed cost of about $4,200. In Whatcom County the variables that move you inside that range are the electrical circuit, the condensate route, and whether the install location has enough air volume.
- How much does PSE pay?
- $1,000, or $1,100 with Efficiency Boost. The unit must be NEEA Tier 3 or Tier 4 and on PSE’s qualified product list, and the home must be an existing single-family PSE electric account. The equipment must be installed on or after January 1, 2026, and the application is due within 30 days of installation with a paid invoice showing install date, address, brand, model and amount.
- Do I get a federal tax credit as well?
- No. §25C terminated for property placed in service after December 31, 2025 under P.L. 119-21, per IRS FS-2025-05. Heat pump water heaters were covered under the old rules and are not covered now.
- Will it work in my garage in January?
- Yes in most Bellingham garages, and it is worth checking the numbers. PSE’s guidance is that the location should stay between 40°F and 90°F year-round with at least 1,000 cubic feet of air volume. An attached, insulated garage here generally holds that; a detached uninsulated one in the foothills may not, and those units fall back on resistance elements when it gets too cold.
- How much condensate does it actually make?
- Several gallons a day, per PSE’s installation guidance, which is why drainage is a design decision rather than an afterthought. We use a floor drain where one exists and a condensate pump where one does not, and we route the discharge somewhere that will not freeze or flood.
- Is it worth it against a plain electric tank?
- Usually yes here, because it is the same electricity doing two to three times the work, and because PSE pays $1,000 toward the difference. A conventional electric tank replacement is published at $600 to $3,100 depending on size, so the up-front gap after the rebate is smaller than most people expect.
