Water heaters, oil (Total: 8)

The Energy Factor (EF) and Uniform Energy Factor (UEF) measure the efficiency of water heaters. After selecting the size required, choose models with a high EF or UEF, as they are the most efficient.

Note:

  • Testing standard: CSA B211-00 for “EF” and CSA P.3-15 for “UEF”
  • The Minimum Energy Performance Standard (MEPS) formulae are equivalent in terms of energy performance, even though they may result in a different number. This is due to the parameters of the different testing standards.
  • Models tested using one specific UEF draw pattern cannot be compared to another model of a different UEF draw pattern.

    • The product models that are displayed in the search results are available in Canada and are covered by Canada's Energy Efficiency Regulations.
