Appliance switch cost compare
Will a heat pump water heater, heat pump dryer, induction cooktop or heat pump save money where you live? It depends mostly on your electricity and gas prices, so type yours.
How this is worked out
- Heat or work needed per year (hot water, drying, cooking, heating) is estimated from your usage. Running cost = that energy / efficiency x price per unit of energy. Gas is converted at 29.3 kWh per therm and propane at 26.8 kWh per gallon.
- Typical efficiencies (editable): water heater UEF about 0.92 resistance, 0.6 gas, 3.0 to 3.5 heat pump; cooktop efficiency 74% resistance, 40% gas, 84% induction (DOE); furnace AFUE 80% default, heat pump HSPF2 7.5 to 9.5 (HSPF2 divided by 3.412 gives seasonal efficiency); heat pump dryers about 1.6 to 2.4 times as efficient as a standard dryer. These are typical figures, not measurements of a specific product.
- Usage assumptions are typical, not measured for your home: 20 gallons of hot water per person per day raised 60 F, 3.3 kWh of site energy per dryer load, 250 / 400 / 600 kWh a year of electric cooking.
- Upfront cost is not guessed: type the extra cost from your quote after rebates and payback follows. We list no prices for products.
- Heat pump efficiency falls in very cold weather and the real figure varies by model and climate. Use the range, not one number.
