Gas and electricity in the same unit
A therm is 29.3 kilowatt hours of energy, so Connecticut's gas works out at 7.68¢ per kWh against 24.16¢ for electricity.
That compares the energy you buy, not the heat you get. A furnace throws away a fifth of every therm up the flue, while a heat pump delivers two to three times the heat in a kilowatt hour — so the cheaper unit here is not automatically the cheaper way to heat a house.
Residential sector, US Energy Information Administration, 2026-07. Updated monthly. Connecticut last reported gas in 2026-05, so that figure is older than the electricity one.

Households in Connecticut use 19% less electricity than the national average and pay 30% more than average. That is a price problem rather than a consumption one — at 24.16¢ a kilowatt hour, even a modest amount of electricity adds up. The climate is fairly balanced — 5,800 heating degree days against 700 cooling ones — so neither season dominates the bill.

What this means for heating
Connecticut sees around 130 freezing nights a year. Whether a heat pump beats a furnace here depends on the gap between those two prices above — not on the equipment.
