Heat pump water heater (HPWH)

Residential methane gas use Pie chart: Hot water 41%, Range/oven 5%, Dryer 2%, Misc 2%, Space Heat 50%
Residential methane gas use (California Residential Appliance Saturation Study – 2009)

If you’re planning to transition to a clean energy home, your water heater is a great place to start. At least 40% of the methane gas used by homes is for heating water.

Heat pump water heaters are clean, safe and all-electric. Peninsula Clean Energy is partnering with the Bay Area wide BayREN Home+ program to offer additional rebates for installing Heat Pump Water Heaters for San Mateo County residents.

 A qualified contractor can evaluate your home and help you understand factors that may affect the ease and cost of installation, including: 

  • Electrical: You may need changes or upgrades to your panel.  You may also need electrical wiring to the point of installation. Rebates can help offset some of the costs! 
  • Location: HPWHs typically have larger space requirements than a methane gas water heater. HPWHs are best suited for installation in a garage, but may be installed in a closet if it is properly ventilated and sound-proofed. Modifications to the existing location or relocation may be needed. 

See below for rebates and next steps for a Heat Pump Water Heater for your home.
