An average house in the Northeast uses less than 700 gallons of fuel oil for heat and hot water for one year. The chart below shows the cost of other fuels providing the same.

The same home with either a System 2000, 90+ Resolute™, Ascent Combi™, or Accel CS™ uses considerably less.

– sold in therms (100,000 BTU/therm)^{1}

- Multiply the oil heat price per gallon by 0.72 to give the equivalent price per therm of natural gas
- Multiply the propane price per gallon by 1.087 to give the equivalent price per therm of natural gas
- Multiply the electricity price per kWh by 29.3 to give the equivalent price per therm of natural gas

– sold in gallons (92,000 BTU/gallon)

- Multiply the oil heat price per gallon by 0.663 to give the equivalent price per gallon of propane
- Multiply the natural gas delivered price per therm by 0.92 to give the equivalent price per gallon of propane
- Multiply the electricity price per kWh by 27.0 to give the equivalent price per gallon of propane

– sold in gallons (138,700 BTU/gallon)

- Multiply the propane price per gallon by 1.507 to give the equivalent price per gallon of heating oil
- Multiply the natural gas delivered price per therm by 1.387 to give the equivalent price per gallon of heating oil
- Multiply the electricity price per kWh by 40.6 to give the equivalent price per gallon of heating oil

– sold in kilowatt hours (3,413 BTU/kilowatt hour)^{2}

- Multiply the propane price per gallon by 0.037 to give the equivalent price per kilowatt hour of electricity
- Multiply the natural gas delivered price per therm by 0.034 to give the equivalent price per kilowatt hour of electricity
- Multiply the heating oil price per gallon by 0.024 to give the equivalent price per kilowatt hour of electricity

– sold in tons or pounds (approximately 8,000 BTU/lb for dry pellets)

- Multiply the oil heat price per gallon by 115 to give the equivalent price per ton of pellets
- Multiply the natural gas delivered price per therm by 160 to give the equivalent price per ton of pellets
- Multiply the propane price per gallon by 174 to give the equivalent price per ton of pellets
- Multiply the electricity price per kWh by 4688 to give the equivalent price per ton of pellets
