Both calculators run independently — change the inputs on either side to compare results.
Heat Pump Savings Calculator (vs Gas or Oil)
Compare the annual heating cost of a heat pump against a gas or oil furnace using your heat demand, the heat pump's COP, furnace efficiency, and both fuel prices. Useful before buying a heat pump or filing for electrification rebates.
Annual heating savings
435.29 $/yr
$200-600/yr is the common range versus gas at moderate rates. The $435 example (COP 3, $0.07 fuel) recoups a typical $4-6k cost premium in roughly 10-14 years.
Savings compare delivered-heat fuel cost against heat-pump electricity cost; a positive number means the heat pump is cheaper to run, driven mainly by COP versus furnace efficiency and the electricity-to-fuel price ratio.
Solar Load Calculator
Calculate the total daily energy demand of your home's lighting, appliances, and HVAC to correctly size a solar system. Use this before getting solar quotes to know exactly how many kilowatt-hours per day you need to generate.
