HeatPumpPayback

Should Reading switch to a heat pump?

In Reading, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Reading's residents would see roughly $48 a year back in running costs, putting the payback around 73.2 years. Reading's own numbers say this pencils out only in theory, not in practice.

Why Reading's climate drives this number

Degree days tell the story here: Reading racks up 4232 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1344 cooling degree days on the cooling side. 12.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 8.1°F on file. Worked through the model, that's a seasonal COP of 3.01 on the cold-climate unit fit for this climate. Reading 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. Climate figures trace to the nearest NOAA station, RDNG RGNL/C A SPAATZ FD AP, 2.9 miles from Reading.

The month-to-month numbers for Reading

Modelled on a typical 2000-square-foot house, the heat pump draws about 3,560 kWh a year to keep it warm, plus cooling, for a combined electric bill near $977 a year. Reading's gas rate of 15.04 per Mcf, applied to the 44 Mcf a year the furnace burns, puts its running cost near $1,024 a year, against 20.75¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 282.4 years; over 15 years the net position sits $2,783 behind.

If your home heats with electric baseboard instead of gas

Plenty of homes in Reading heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Reading's answer improves. Switching saves about $1,608 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 5 years.

How Reading compares nationally

Reading lands at position 1388 out of 3206 cities on heating severity (coldest is 1), and 359 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

More on how this number was built

The methodology guide walks through exactly how Reading's 3.01 seasonal COP and the rest of this page's numbers get built. Reading's 12.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
