Residential Boiler Standards Begin Sept. 1

August 20, 2012
CALGARY, Alberta — In October 2011, Natural Resources Canada (NRCan) published amendment 11 to the Energy Efficiency Regulations in the Canada Gazette part II. Affected products include residential gas, oil, and electric boilers with an input rate of less than 88 kW (300,000 Btuh). The amended regulations introduce prescriptive requirements in addition to strengthening the minimum energy performance standards.

One critical prescriptive requirement involves an automatic means for adjusting water temperature. All gas, oil, and electric hot water residential boilers must adjust the temperature of the water supplied by the boiler to ensure that an incremental change in inferred heat load produces a corresponding incremental change in temperature of the water supplies. In particular, a boiler for which an automatic means for adjusting water temperature is required shall be operable only when the automatic means is installed.

All gas, oil-fired, and electric hot water boilers that have their manufacturing process completed on or after Sept. 1, 2012 will be required to meet the prescriptive requirement of an automatic means of adjusting water temperature.
