Commercial Heating Calculator

Use this tool to estimate what your annual heating costs would be using different heating systems.

  1. Change the variables in the blue-shaded section to reflect the specifications and costs of your current heating system.
  2. Click “Calculate” to see the results of changes to variables.
  3. Click “Reset” to restore default values.

Notes:

  • Changing the “Cost Per Unit” in the blue-shaded section will automatically change the same-type fuel costs in the main table.
  • Changing “System Efficiency” or “Distribution Efficiency” in the blue-shaded section will NOT affect the same values in the main table. This allows for comparisons between different systems.
