Equipment category · 6 eligible programs
Heat pump water heater rebates for PNW homeowners.
Hybrid heat-pump water heaters — replace gas or electric resistance tanks with units that pull heat from surrounding air.
Why it matters
The case for hpwh rebates
HPWH cuts water-heating energy use by 60-70% versus electric resistance, and is one of the highest-ROI residential electrification swaps available in the PNW. Federal HEEHRA covers up to $1,750 alone.
Typical install scope
What "hpwh" usually involves
Replaces existing tank; needs ambient air volume (~700 cu ft minimum) — basement, garage, or utility room ideal, smaller closets may not qualify. Some units have ducted intake/exhaust options for tight spaces.
Pacific Northwest context
What's different about PNW installs
PNW basements and garages are well-suited for HPWH — mild ambient temps year-round mean the unit operates near peak efficiency most of the year. Cold ambient (under 45°F) reduces efficiency; conditioned-space install is preferred.
Install notes
What to confirm with your installer
UEF (Uniform Energy Factor) rating matters for rebate eligibility — typically need UEF ≥ 2.5 or 3.0 depending on program. Most major brands (Rheem, AO Smith, Bradford White) have eligible HPWH lines; smaller resi units may not meet the UEF tier.

HEEHRA — Home Electrification & Appliance Rebate →
Each state administers HEEHRA differently. WA's implementation launched 2025; check status before assuming current availability — funding can run out per program-year.
Utility
PSE Energy Efficiency Incentives →
PSE separates electric and gas incentives. If converting from gas to heat pump, you may unlock both gas-side (decommission) and electric-side (install) rebates. Check the contractor finder for PSE Trade Allies.

Tacoma Power Rebates →
Some Tacoma Power rebates have income tiers — moderate-income homeowners get higher rebate amounts. Cross-check with HEEHRA stacking eligibility.
