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.


The calculator provides general estimates on what energy costs may be expected from the heating systems being considered. The calculator does not consider annual maintenance costs. More complex heating systems may come with higher maintenance costs. The total lifetime cost of a heating system is the cost to buy and install the heating system plus the annual energy cost over the life of the heating system. All such estimates are general in nature and the estimates are based on information received from the user of the calculator and Manitoba Hydro is relying solely on the information and representations being made by the user and that the estimates are based on other external factors such as weather, use of equipment, systems and type and use of eligible upgrades. The natural gas rate used in the calculator is based on a rolling average of the current quarterly natural gas rate and the three previous quarterly rates that were in effect. The propane and fuel oil rates used in the calculator are based on a rolling average of the current point-in-time price (at the time of the current quarterly natural gas rate) and the three previous quarterly rates that were in effect. As electricity rates typically change on an annual basis the current electricity rate is used. Depending on your supplier, propane and fuel oil prices can fluctuate on a daily basis. The annual heating costs presented by the calculator exclude the cost of converting to a different heating system, which may be significant. Manitoba Hydro recommends that you speak with a licensed heating contractor to get quotations on a new space or water heating system to better understand the total cost of switching heating systems. Manitoba Hydro does not make any guarantees, representations or warranties respecting any estimates provided by or on behalf of Manitoba Hydro, either express or implied, arising by law or otherwise, as to any matter including without limitation merchantability, effectiveness, efficiency, completeness, currency, accuracy, correctness, fitness for a particular purpose. The user of the calculator shall be solely responsible for the entire risk of the performance and results of the estimate and any and all claims or liabilities that might arise as a result of the use of the estimate.
