Oil-fired boilers

Energy Efficiency Regulations

Regulatory definition

Oil-fired boiler, a boiler that is intended for application in a low pressure steam or hot water central heating system, that has an input rate of less than 88 kW (300 000 Btu/h) and that is either exclusively oil-fired, or capable of being fired, at the choice of the user, by either oil or another fuel.

Compliance date

Manufactured on or after September 1, 2012 for meeting prescriptive requirement of an automatic means for adjusting water temperature.
