HeatPumpPayback

Verona, WI: the heat pump payback math

Verona is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Verona 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. Unfortunately the electric bill outweighs the gas bill it replaces by about $403 a year here, so the extra spend stays unrecovered. There's no spin on that: Verona's numbers say wait.

Why Verona's climate drives this number

5775 heating degree days pile up here every year, so Verona has a cold winter that leans hard on heating equipment; the cooling side runs to 761 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: -9°F here (record low -11°F), which works out to a seasonal COP of 2.48 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Verona — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Verona's running-cost comparison, in dollars

Electricity use for heating alone comes out to about 5,896 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,235 a year. Verona's gas rate of 10.74 per Mcf, applied to the 60 Mcf a year the furnace burns, puts its running cost near $832 a year, against 18.87¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $9,545 behind.

The other scenario: no gas furnace to begin with

Gas isn't universal in Verona — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Verona's answer improves. The saving here runs about $1,710 a year, which recovers the extra $8,000 spent going electric in roughly 4.7 years.

Where Verona ranks in this dataset

Ranked against the other 3206 cities covered, Verona comes in at 288 for heating severity — 1 would be the coldest place in the dataset — and 2212 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
