Is a heat pump worth it in Westerville?
The payback math works in Westerville on paper, past the equipment's own working life. $3,500 is what Westerville would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $42 saved annually, for a payback of roughly 83.5 years. Westerville's own numbers say this pencils out only in theory, not in practice.
Why Westerville's climate drives this number
Degree days tell the story here: Westerville racks up 4107 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1482 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 6.1°F, against a record low of 5°F. That puts the seasonal coefficient of performance at 2.85 for the recommended cold-climate unit. A cold-climate unit is the right call in Westerville — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The month-to-month numbers for Westerville
Electricity use for heating alone comes out to about 3,649 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $904 a year. That compares with roughly 43 Mcf a year of gas at Westerville's 13.85 per-Mcf rate — about $946 a year — against a local electricity rate of 18.40¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 322.2 years, leaving the 15-year total $2,871 behind.
Electric resistance heat in Westerville, compared
Plenty of homes in Westerville heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,363 a year comes back this way, enough that the 5.9-year payback clears the $8,000 premium comfortably within the equipment's life.
Westerville against the rest of the country
Among 3206 cities, Westerville's winter puts it at rank 1447 for severity, while its size puts it at rank 1071 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
