Gas vs Electric Heating Cost in Florida

In Florida, a 2,000 sq ft house with average insulation costs an estimated $314.45 a year to heat with a 92% gas furnace, $518.03 with electric resistance heat and $152.36 with a heat pump. Here the heat pump line comes in lowest: $12.96 per MMBtu of heat against $26.74 for gas.

At 15.0¢/kWh, Florida has the 37th-highest electricity rate among the 50 states and DC. Natural gas is $2.46/therm in Florida, 66% above the US average of $1.48/therm, so a 92% furnace's heat costs $26.74 per MMBtu. With 700 heating degree-days (NOAA), the 2,000 sq ft example in Florida needs 11.8 MMBtu of heat a year, less than at the US average of 4,500.

Worked example

Worked example: 2,000 sq ft in Florida

A 2,000 sq ft house with average insulation in Florida needs about 11.8 MMBtu of heat a year (700 heating degree-days). At $2.46/therm in a 92% furnace, gas delivers that heat at $26.74 per MMBtu; resistance heat at 15.0¢/kWh costs $44.05, and a heat pump at seasonal COP 3.4 (zone 2) costs $12.96. The year comes to $314.45 on gas, $518.03 on resistance heat and $152.36 on a heat pump. The heat pump is the cheapest to run here, by $162.09 a year over gas.

Load = sq ft × 0.35 × heating degree-days × 24 ÷ 1,000,000. Gas $/MMBtu = $/therm ÷ 0.1 ÷ 0.92. Resistance $/MMBtu = $/kWh × 293.07. Heat pump = resistance ÷ COP.

Questions

FAQ

Which is cheaper in Florida, gas or electric heat?

Electric resistance heat is the most expensive of the three in Florida: $518.03 a year for the 2,000 sq ft example, $203.58 more than gas. Between gas ($314.45) and a heat pump ($152.36), the heat pump is cheaper here: its heat costs $12.96 per MMBtu, gas $26.74. These are estimates at 15.0¢/kWh and $2.46/therm; your bill's prices can change the answer.

How much gas does a furnace use in Florida?

About 128 therms a year for a 2,000 sq ft house with average insulation and a 92% furnace, at Florida's 700 heating degree-days. That averages 11 therms a month over 12 months, but almost all of it is burned in the heating months. At $2.46/therm, the year costs an estimated $314.45.

Electric furnace vs gas furnace cost in Florida?

An electric furnace is resistance heat: every kWh gives 3,412 BTU. At 15.0¢/kWh, that heat costs $44.05 per MMBtu in Florida, against $26.74 from a 92% gas furnace at $2.46/therm, 1.6 times as much. For the 2,000 sq ft example that's $518.03 a year against $314.45.
