Dehumidifiers – July 2016

Technical bulletin on amending the standard

Webinar – July 2016

This technical bulletin has been released to initiate the consultation process and to collect stakeholder views on the requirements being considered for dehumidifiers in the next amendment to the Energy Efficiency Regulations (the Regulations).

Input received from stakeholders during this stage of the process will inform the development of the Amendment 14 proposal.  In addition, the department will undertake a cost-benefit analysis using the best-available Canadian market data to assess the economic and environmental impacts of aligning these standards and to ensure Canadian consumers and businesses benefit from its implementation.

The Government of Canada intends to pre-publish a regulatory proposal in the Canada Gazette, Part I within approximately one year of this bulletin.


Dehumidifiers are regulated products in Canada since 1998.  In June 13, 2016, the United States Department of Energy (U.S. DOE) issued a final rule, which increased the stringency of minimum energy performance standards (MEPS) using an integrated energy factor for dehumidifiers and expanded the scope to include whole home dehumidifiers, effective as of June 13, 2019.

Natural Resources Canada (NRCan) is considering moving dehumidifiers from Amendment 15, as initially posted in NRCan’s 2016-2018 Forward Regulatory Pan, and adding it to the list for Amendment 14.

Product description

The Regulations would continue to cover portable residential dehumidifiers that are used to remove moisture from the air.  The product scope would be expanded to include whole home dehumidifiers that are designed to be installed in a ducted system.

Energy performance test procedure

NRCan is proposing that the following energy performance test procedure be referenced:

The Canadian Standards Association is in the process of revising CSA C749 - Energy performance of dehumidifiers which may be considered as an alternative test procedure when it is completed.

Energy performance standard

NRCan is considering a minimum integrated energy factor for dehumidifiers as found in the United States CFR Title 10 CFR Part 430, Subpart C, §430.32 (v)(3):

MEPS under consideration for dehumidifiers
Product class Minimum integrated energy factor (L/kWh)
Portable dehumidifier product capacity (pints/day)
25.00 or less 1.30
25.01 - 50.00 1.60
50.01 or more 2.80
Whole-home dehumidifier product case volume (cubic feet)
8.0 or less 1.77
More than 8.0 2.41

Effective dates

These Regulations would come into force six months after the date of publication in the Canada Gazette, Part II.

NRCan is considering applying these more stringent standards to dehumidifiers that are manufactured on or after June 13, 2019.

Verification requirements

There is no change being considered for the energy efficiency verification requirements for this product.

Reporting requirements

Energy efficiency reports

The energy efficiency report required for dehumidifiers would include the following product specific information in addition to the reporting requirements already in place:

  • integrated energy factor in L/kWh
  • case volume in cubic feet (for whole house dehumidifiers)

The Regulations apply to products imported or shipped inter-provincially for sale or lease in Canada. This report must be submitted, by the dealer, to NRCan before the product is imported into Canada or traded interprovincially for the first time.

Import reports

There is no change being considered to the import reporting requirements for dehumidifiers

Comments invited

The purpose of this bulletin is to provide stakeholders with technical detail required to comment on the requirements under consideration for dehumidifiers.
