Gas-fired unit heaters

Energy Efficiency Regulations

Regulatory definition

Gas-fired unit heater, a self-contained, automatically controlled, vented, gas-burning appliance that distributes warmed air without the use of ducts and that has an input rate of not more than 2931 kW (10 000 000 Btu/h).

Compliance date

Manufactured on or after August 8, 2008

For models manufactured prior, refer to the Regulations

Testing standard

CAN/CSA-P.11-2007

Energy efficiency standard

Energy performance test standard for gas-fired unit heaters

Thermal efficiency must be at least 80% at the maximum heat input nominal capacity, and must be equipped with an intermittent ignition device and:

• a power-vented system
• an automatic vent damper
• an automatic flue damper

Energy efficiency report requirements

• name of product
