What Connecticut 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, Connecticut heating oil delivers heat at $47.67 per million BTU.
| Equipment | Efficiency | $ / million BTU delivered |
|---|---|---|
| Older oil boiler / furnace | 80% AFUE | $50.05 |
| Mid-efficiency | 84% AFUE | $47.67 |
| Modern condensing | 87% AFUE | $46.03 |
The other heating fuels in Connecticut
At today's prices natural gas and a heat pump both deliver the same heat for less than heating oil does here — before any equipment cost.
| Fuel | Price | $ / million BTU delivered |
|---|---|---|
| Natural gas | $23.33/Mcf | $25.00 |
| Electricity (cold-climate heat pump) | 27.37¢/kWh | $36.46 |
| Propane | $4.116/gallon | $49.98 |
| Electricity (baseboard) | 27.37¢/kWh | $80.22 |
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.
