On March 4, 2018, Natural Resources Canada (NRCan) issued a notice of intent including a technical bulletin on developing standards on gas and oil-fired commercial boilers.  The notice can be found here.

On March 8, 2018, NRCan hosted a webinar to discuss new product categories in Energy Efficiency Regulations for gas and oil-fired commercial boilers.  Items covered included an overview of the federal regulatory process and proposed minimum energy performance standards for commercial boilers.

Proposed for Canada in 2023 is a minimum efficiency level of 90% AFUE for both small gas hot water boilers and large gas hot water boilers in both the new and replacement markets. The U.S. DOE pre-published final rule should be effective in 2023, and should set minimum efficiency levels of 84% for small gas hot water boilers, and 85% for large gas hot water boilers.

During the webinar, NRCan’s representatives noted that under Canada’s Pan-Canadian Framework on Clean Growth and Climate Change, energy efficiency standards are expected to play a role in the strategy to achieve climate change goals. They are proposing to exceed the minimum standards for space heating and water heating in the U.S. where it makes sense.

NRCan is proposing to harmonize with the U.S. DOE final rule for large and small gas steam boilers also with a compliance date of 2023.

A presentation on cost/benefit assumptions and energy savings analysis was included in the Webinar on March 8th, to provide a financial perspective on the rationale for the proposed amendments which are not in line with the U.S. DOE requirements. Industry members who participated in the webinar expressed concern that assumptions used in the presentation were incorrect. 

NRCan has requested that stakeholders submit comments on the technical bulletin by April 6th or preferably sooner. HRAI, AHRI and CIPH will submit comments on behalf of members. Pre-publication of the regulation is proposed for the fall of 2018.  A 75 day comment period will follow pre-publication.
