Energy efficiency standard

Thermal efficiency ≥ 80% at the maximum heat input nominal capacity and must be equipped with

  • an intermittent ignition device

and either

  • a power-vented system,
  • an automatic vent damper or
  • an automatic flue damper.

Requirements for the energy efficiency report prior to import, as listed in Schedule IV of the Regulations

  • type of product (gas-fired unit heaters)
  • brand name
  • model number
  • manufacturer
  • name of the organization or province that carried out the gas-fired unit heaters verification and authorized the verification mark that will be affixed to the product
  • fuel the product uses: propane or natural gas
  • type of ignition system the product uses
  • type of venting the product uses: power-vented system, automatic vent damper or automatic flue damper
  • maximum heat input and output nominal capacities in kW
  • thermal efficiency when at its maximum heat input nominal capacity
  • electricity consumption in kWh when at its maximum heat input nominal capacity and
  • if the product is a modulating or staged control gas-fired unit heater:
    • reduced heat input and output nominal capacities in kW, and
    • electricity consumption in kWh when at its reduced heat input nominal capacity.
