Home Heating Cost in Delaware (2027): Natural Gas vs Oil vs Electric
Heating costs for your home size in Delaware
Every figure below starts from Delaware's current average energy prices and runs them through the seasonal model behind our heating cost calculator: a Climate Region #3 heating load sized to your home, served by standard mid-efficiency equipment.
Take a 2,270 sq. ft. Delaware home: a heat pump is the low-cost fuel at about $1,980 a season, and electric baseboard heat sits at the other end near $5,550. Same house, same winter: a gap of about $3,580.
One Winter of Heat in Delaware, Priced by Fuel

| Electric heat pumpductless, ~2.9 COP | $0.225per kWh | 8,750kWh | ~$1,980 |
| Natural gasnatural gas boiler, 82 AFUE | $2.08per therm | 1,056therms | ~$2,200 |

Rounded up to $10. Rates are current Delaware averages; the load is a 2,270 sq. ft. home at the insulation level you pick above. Same method as the heating cost calculator.
A Season of Heat, Fuel by Fuel
Same house, same winter, five fuels. Hover a bar for the use and the rate behind it.
Season = the modeled Delaware heating load on standard mid-efficiency equipment; fuels ranked like the heating cost calculator (pellet and wood stoves are manual-load and stay unranked).
What 10 Winters of Heat Could Cost in Delaware
A fuel that wins this winter can lose later if its price climbs faster. The electric lines below rise at Delaware's own electricity trend, about 3.37% a year from 2013 to 2023. For natural gas, heating oil and propane our data has no comparable history, so you choose: hold them at today's price, or let them climb at the electricity pace. Tap or hover any winter to read the numbers.
Season costs at average insulation; winter 1 is today's prices. Totals rounded up to $10.
If natural gas, heating oil and propane stay at today's prices, natural gas costs about $21,970 over 10 winters here, against about $64,650 for electric baseboard heat. The heat pump starts cheaper than natural gas, but passes it in winter 5 if natural gas prices hold still.
Why Delaware Weather Shapes the Heating Bill
With winter highs around 44°F and lows around 27°F, Delaware lands in Climate Region #3. It's a mixed climate: a real heating season, and a cooling season that matters too.
Weather factors that affect heating in Delaware:
Salt air. Near the coast, salt spray corrodes the outdoor coil and cabinet of a heat pump. Coated coils and a freshwater rinse once a year extend its life.
Damp cold. Moist air near freezing frosts a heat pump's outdoor coil, so the unit pauses to defrost now and then. That is normal; a model with demand-based defrost wastes less energy doing it.
Cold-snap failures. A heating breakdown during a hard freeze can mean burst pipes by morning. A fall tune-up, spare filters and a temperature alert on the thermostat are cheap insurance.
With both a heating and a cooling season, spring and fall are the quiet times for installers. Replacing heating and cooling together often saves on labor.
Beyond Fuel: Where Heating Money Leaks
- The shell of the house. A well-insulated home needs about 12% less heat than an average one in this model, and a drafty one about 12% more; with a heat pump in Delaware, each step is worth about $240 a season.
- The ducts. A forced-air system with bare ducts loses roughly 17% of its output on the way to the rooms, according to the calculator's duct model. Ductless systems and radiators skip that loss.
- Burner efficiency. The table assumes a mid-efficiency boiler at 82 AFUE. A condensing unit at 93 AFUE burns less fuel for the same heat, about $260 a season less on natural gas here. An old 62 AFUE unit burns about $710 more.
How a Heat Pump Changes the Electric Bill
A heat pump is an air conditioner that runs in reverse in winter. Pulling heat from outdoor air, it yields about 2.9 kWh of warmth for every kWh it uses in Delaware. Same $0.225 rate, but about $3,580 less per season than baseboard heat. That also makes it the least expensive fuel here.
Delaware Heating: Quick Answers
What is the cheapest way to heat a home in Delaware?
At current rates the winner is a heat pump, about $1,980 a season for this house; natural gas follows at about $2,200. A heat pump needs only an electric connection, so it is an option for almost any home.
Is it worth switching off heating oil in Delaware?
On fuel cost, yes. Heating oil runs about $4,600 a season for this house; a heat pump would cost about $1,980. Over 10 winters at today's prices that gap is about $26,290: the budget a conversion has to beat.
Is insulation worth it for heating in Delaware?
With a heat pump, a poorly insulated 2,270 sq. ft. home costs about $2,210 a season and a well-insulated one about $1,740. That $480 gap repeats every winter.
Wood and pellet stoves are not ranked here because someone has to load them. The pellet stove calculator prices them on their own.
