Our Picks
How HPWH Works
Heat pump pulls heat from ambient air and transfers it to water. Like a backwards refrigerator. The garage cools 5-10°F (welcome in California summers); water heats efficiently.
Backup electric heating elements kick in for high-demand periods.
California Rebates
2026 rebate stack: $1,000-$2,000 from PG&E or SCE. Federal tax credit 30% of project cost (up to $2,000 max). California Energy Commission TECH program: $1,000-$3,000 additional.
Total rebates often exceed $3,000-5,000. Making HPWH cheaper installed than a comparable electric tank.
Sizing
50-gallon tank serves 2-3 person households. 65-gallon serves 4-5. 80-gallon serves 5+. HPWH tanks must match or exceed standard tank capacity for similar-load homes.
Install Considerations
HPWH needs 1,000+ cubic feet of conditioned/semi-conditioned air. Garages typically work; small utility closets often don't. Drainage required for condensate.
Install requires standard 240V circuit (15-30A). Same as electric tank.
