HeatPumpPayback

Should Davenport switch to a heat pump?

In Davenport, a heat pump would cost more to run each year than what you have now. $3,500 is what Davenport 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 $85 a year here, so the extra spend stays unrecovered. There's no spin on that: Davenport's numbers say wait.

Why Davenport's climate drives this number

Degree days tell the story here: Davenport racks up 5207 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 896 cooling degree days on the cooling side. -9.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -15°F on file. Worked through the model, that's a seasonal COP of 2.46 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Davenport sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from DAVENPORT MUNICIPAL AIRPT, the closest NOAA station, 4 miles out.

Davenport's running-cost comparison, in dollars

Electricity use for heating alone comes out to about 5,360 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $815 a year. The gas furnace it replaces burns roughly 54 Mcf a year at 10.61 per Mcf here, for a running cost near $730 a year (electricity here runs 13.31¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $4,777 behind.

Electric resistance heat in Davenport, compared

Gas isn't universal in Davenport — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,094 a year, which recovers the extra $8,000 spent going electric in roughly 7.3 years.

How Davenport compares nationally

Davenport lands at position 555 out of 3206 cities on heating severity (coldest is 1), and 336 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.

Deciding what's next in Davenport, IA

About 100,938 people live in Davenport, Iowa, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

More on how this number was built

Every constant behind this page — the 2.46 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a -9.9°F design temperature, Davenport sits in cold-climate territory; the guide to that class of unit explains why.
