Compare Heating System Costs

Estimate and compare annual heating costs across the fuels and systems we install. Enter your local fuel prices below (defaults are rough regional estimates), adjust efficiency if you know your equipment's rating, and set your home's approximate annual heating load to see estimated yearly cost side by side.

million BTU / year Not sure? A typical mid-size Maine or New Hampshire home needs roughly 50–90 million BTU of heat per year depending on size and insulation — adjust up or down, or use last year's fuel usage to calibrate.

Estimates only — based on standard fuel heat-content conversions (heating oil ≈139,000 BTU/gal, propane ≈91,500 BTU/gal, natural gas 100,000 BTU/therm, electricity 3,412 BTU/kWh, wood pellets ≈16.5 million BTU/ton) and typical equipment efficiency ratings, which you can edit above to match your own equipment. Actual costs vary with your home's insulation, local weather, equipment condition, and current fuel prices — use this tool to compare relative costs, not as a guaranteed quote.
