This calculator lets you compare the costs of your current home heating system with the savings offered by newer equipment and other sources of energy. It is for homes using one heating source: electricity, natural gas, propane or oil. The results should be used only as a guide. For a detailed evaluation, consult a heating contractor or other qualified professional.
The calculator requires that you enter the following information:
Current cost of fuel for space heating (fuel cost per unit)
Current cost of fuel for hot water (fuel cost per unit)
Total annual heating costs (based on your fuel bills)
Price of purchasing new heating or hot water equipment (including installation and taxes)
Value of any rebate or incentive received for purchasing new equipment
