Ohio energy rates pre-filled from EIA. Estimate your heating cost below, and see the assumptions behind every figure.
Electricity: EIA Electric Power Monthly, Table 5.6.A, May 2026. That is a single month, not a 2026 annual average — annual state figures are not published until the following year. Natural gas: EIA Natural Gas Monthly residential price, winter average, Dec 2025 – Feb 2026, converted to $/therm. “Lowest running cost” is a calculation from those rates, not a survey of what people own: it is whichever system delivers a unit of heat for the least money in Ohio, comparing a heat pump at a seasonal COP of 2.4 against a 92% AFUE gas furnace. Rates vary by provider and season.
Ohio averages 29.5°F in winter. Cold winters (avg 29.5°F) and gas at $1.13/therm make a gas furnace about 49% cheaper per unit of delivered heat than a heat pump here.
On running cost alone a 92% AFUE gas furnace wins in Ohio: about $0.0123 per 1,000 BTU delivered, against $0.0238 for a heat pump at a seasonal COP of 2.4 — roughly 49% less. Gas is not available at every address, and a heat pump also cools.
Ohio electricity costs 19.52¢/kWh, about 6% above the US average of 18.44¢/kWh (EIA Electric Power Monthly, Table 5.6.A, May 2026). Where electricity is expensive, the efficiency of the equipment matters more: a heat pump buys the same heat for a fraction of the kilowatt-hours a resistance heater needs.

Based on Ohio EIA rates: 19.52¢/kWh electricity (May 2026), $1.13/therm gas (winter average, Dec 2025 – Feb 2026).
| Heater Type | Small Home | Medium Home | Large Home |
|---|---|---|---|
| Electric Resistance | ~$439/mo | ~$731/mo | ~$1097/mo |
| Gas Furnace (92% AFUE) | ~$94/mo | ~$157/mo | ~$235/mo |
| Heat Pump (COP 2.4) | ~$183/mo | ~$305/mo | ~$457/mo |
How these are worked out. Whole-home heating for a full winter month, not a plug-in heater. We take Ohio's 29.5°F average winter temperature, which gives about 1,065 heating degree days in a 30-day month against a 65°F base, and multiply by a heat-loss coefficient of 300 (small, ~1,000 sq ft), 500 (medium, ~2,000 sq ft) or 750 BTU/hr/°F (large, ~3,000 sq ft) for an average-insulated home. That delivered heat is then priced at the rates above, at the efficiencies shown in each row. Those coefficients are round engineering figures, not measurements — they exist so every page on this site derives monthly cost the same way. A poorly sealed house can easily run double these numbers.
Figures above are calculated from EIA Electric Power Monthly, Table 5.6.A (May 2026) and EIA residential natural gas prices, using a seasonal COP of 2.4 for a heat pump in Ohio's climate and 92% AFUE for a modern condensing gas furnace.
