Calculate heating costs

This calculator will help you make an informed decision about replacing or upgrading your space or water heating system. You may use it to:

  • Select and compare your home heating system options;
  • Select and compare your water heater options;
  • Compare the annual operating costs as well as the total lifetime costs of your options;
  • The total lifetime cost is the estimated purchase price plus the operating cost over the life of the system;
  • The estimated life is 25 years for a space heating system and 10 years for a water heating system;
  • Save, print, or share the report so that you may discuss the information with your contractors.
