Gatesville, TX: the heat pump payback math

In Gatesville, the math is close enough that it comes down to how long you plan to stay. $3,500 is what Gatesville 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. Gatesville's residents would see roughly $327 a year back in running costs, putting the payback around 10.7 years. It's a genuine toss-up here — Gatesville's numbers don't point clearly either way.

How cold Gatesville actually gets

Degree days tell the story here: Gatesville racks up 1551 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 3062 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 15.8°F, against a record low of 14°F. That puts the seasonal coefficient of performance at 3.08 for the recommended cold-climate unit. Gatesville needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from GATESVILLE MUNICIPAL AIRPORT, the closest NOAA station, 3.5 miles out.

The month-to-month numbers for Gatesville

Modelled on a typical 2000-square-foot house, the heat pump draws about 1,275 kWh a year to keep it warm, plus cooling, for a combined electric bill near $628 a year. The gas furnace it replaces burns roughly 16 Mcf a year at 19.42 per Mcf here, for a running cost near $955 a year (electricity here runs 16.15¢/kWh). Buy it outright, not incrementally, and payback stretches to 41.3 years; over 15 years the net position sits $1,405 ahead.

Electric resistance heat in Gatesville, compared

Plenty of homes in Gatesville heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Gatesville's answer improves. The saving here runs about $648 a year, which recovers the extra $8,000 spent going electric in roughly 12.4 years.

Gatesville against the rest of the country

Ranked against the other 3206 cities covered, Gatesville comes in at 2673 for heating severity — 1 would be the coldest place in the dataset — and 2261 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.

Where Gatesville's figure comes from

Every constant behind this page — the 3.08 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Gatesville's 15.8°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
