The Cheapest Way to Heat Your Home in 2026
A heat pump is the cheapest way to heat most US homes in 2026 at roughly $0.013 per 1,000 BTU. It moves heat from outdoor air rather than generating it, delivering 3 units of heat for every 1 unit of electricity. This makes it cheaper than natural gas in most states and dramatically cheaper than propane or electric resistance.
Natural gas remains the second-cheapest option at $0.015 per 1,000 BTU, but only where gas lines exist. In rural areas without gas service, propane at $0.018 per 1,000 BTU is the next best choice. Electric resistance at $0.038 per 1,000 BTU is the most expensive and should only be used as a last resort or in very mild climates.
The 2026 Federal tax credit makes heat pumps even more attractive — 30% of costs up to $2,000. For a 1,500 sq ft home in a moderate climate, annual savings versus electric resistance are roughly $1,560. Even versus gas, a heat pump saves $300–$500 per year.
