HeatCost: Heating Cost Compare

HeatCost tells you which heating fuel actually costs the least — per unit of useful heat, not per gallon, liter or cord.

Enter the price you pay for each fuel and your appliance's efficiency. HeatCost ranks every fuel by cost per delivered MMBTU (or GJ) and projects your annual heating cost, so firewood, pellets, propane, heating oil, natural gas, electric resistance and heat pumps are compared on equal terms.

SEE THE PAYBACK OF SWITCHING
Pick the heating you use today. HeatCost shows the yearly saving (or extra cost) of every alternative. Add the price of new equipment and you get the payback years at a glance.

YOUR BILL'S UNITS
Switch the purchase unit per fuel: gallons or liters, therms, CCF, m³ or kWh for gas, cords or m³ for firewood, tons, tonnes, kg or bags for pellets. Energy content and price are converted together, so the ranking never changes.
