Deerfield Beach, FL: the heat pump payback math
The math in Deerfield Beach isn't close — a heat pump wins outright. $1,000 is what Deerfield Beach 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. Deerfield Beach's residents would see roughly $340 a year back in running costs, putting the payback around 2.9 years. That verdict holds specifically for Deerfield Beach's own climate and rates, not a national average.
Deerfield Beach's weather, in the numbers that matter
Deerfield Beach barely has a winter to speak of — 55 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 4842 cooling degree days. Sizing runs off the design temperature, not the average day: 52°F here (record low 48.9°F), which works out to a seasonal COP of 3.75 for the standard class of unit this climate calls for. Deerfield Beach's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. Climate figures trace to the nearest NOAA station, POMPANO BEACH AIRPARK ARPT, 4.4 miles from Deerfield Beach.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 37 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $643 a year. The gas furnace it replaces burns roughly 1 Mcf a year at 25.48 per Mcf here, for a running cost near $983 a year (electricity here runs 15.43¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 32.3 years, for a 15-year net position $4,102 ahead.
Electric resistance heat in Deerfield Beach, compared
Plenty of homes in Deerfield Beach heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Deerfield Beach's answer improves. The saving here runs about $347 a year, which recovers the extra $5,500 spent going electric in roughly 15.8 years.
Deerfield Beach against the rest of the country
Deerfield Beach lands at position 3176 out of 3206 cities on heating severity (coldest is 1), and 392 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
