Your rates

Based on 3CE and PG&E's rates for the standard time-of-use plan (E-TOU-C), current as of March 2026. Use the rate on your own bill if you have it.

Based on PG&E's residential gas rates for the 12 months to October 2026. Use the rate on your own bill if you have it.

Appliance by appliance

  1. HVAC Heat Pump HVAC

    Heat pumps provide heating and cooling. Our model assumes a COP of 3; ENERGY STAR says an air-source heat pump can deliver up to three units of heat per unit of electricity. Actual performance varies.

    Per year
    -$360
    Running total
    -$360
  2. Water heater HP Water Heater

    Our model assumes a COP of 3. DOE says heat-pump water heaters can be two to three times as efficient as conventional electric water heaters; actual performance varies.

    Per year
    -$144
    Running total
    -$504

The totals

  • Gas burned today700 therms
  • Gas cost today$1,946
  • Electric cost after$2,450
  • CO₂ avoided per year2,561 kg
  • Projected over the horizon (25 years)-$27,666
  • Savings per year-$504

This shows energy savings only. What an install costs depends on your existing setup, so that number comes from a consultation.

What's in this number

Each appliance converts its yearly gas use to the electricity an equivalent heat-pump or induction appliance would draw, using 29.3 kWh per therm, an assumed 80% gas-appliance efficiency for this calculator, and the assumed performance of its electric replacement. Savings compare what you spend on gas today against what that electricity costs at your rate. Our assumptions use ENERGY STAR’s heat-pump benchmark, DOE’s water-heater comparison and ENERGY STAR’s cooking efficiencies. DOE’s archived pool-heater guidance gives COP 3–7 at 80°F air and water; colder air reduces performance. Its gas-heater guidance lists some new heaters at 89–95%. These are reference benchmarks, not a measurement of your appliances. The federal Section 25C credit that used to help with heat pump and supporting panel costs ended for work placed in service after December 31, 2025, so no federal credit is applied here. This tool shows annual energy savings only — install costs come from a real consultation.
