What Indiana heating oil costs to heat with
A price per gallon says nothing on its own — equipment efficiency decides how much of it reaches the room. At a mid-efficiency boiler at 84% AFUE, Indiana heating oil delivers heat at $40.23 per million BTU.
| Equipment | Efficiency | $ / million BTU delivered |
|---|---|---|
| Older oil boiler / furnace | 80% AFUE | $42.24 |
| Mid-efficiency | 84% AFUE | $40.23 |
| Modern condensing | 87% AFUE | $38.84 |
The other heating fuels in Indiana
At today's prices natural gas, a heat pump and propane all deliver the same heat for less than heating oil does here — before any equipment cost.
| Fuel | Price | $ / million BTU delivered |
|---|---|---|
| Natural gas | $13.70/Mcf | $14.68 |
| Electricity (cold-climate heat pump) | 18.15¢/kWh | $24.18 |
| Propane | $2.634/gallon | $31.99 |
| Electricity (baseboard) | 18.15¢/kWh | $53.19 |
Electricity is shown twice on purpose: a heat pump and a baseboard heater run on the same electricity but differ by a factor of two, so quoting one figure for "electric heat" would be meaningless. Combustion figures assume a 90% AFUE furnace. Nothing here includes the cost of buying or installing the equipment, which is usually what decides a switch. How the fallbacks work.
