Energy Efficiency Regulation
Regulatory definition
Line Voltage Thermostat, a device that is used with a line voltage of between 120 V and 240 V, is intended for switching of a controlled resistive heating load and is one of the following:
- a wall-mounted thermostat designed to be used with baseboards, panel convectors or radiant floors;
- a built-in thermostat having a nominal load from 1000 W to 1500 W that is used in baseboards or panel convectors; or
- a two-component thermostat. (thermostat à tension de secteur)
The definition line voltage thermostat in subsection (1) does not include thermostats designed to be used exclusively for or built into
- fan-forced heaters;
- kick space heaters;
- fireplaces;
- thermal storage heaters;
- electric baseboards and convectors incorporating both convection and radiant heating elements;
- portable heaters; or
- central heating units under the control of a single thermostat.
Compliance Date
In the case of a wall-mounted thermostat or a two-component thermostat, it is manufactured on or after July 1, 2026; and
In the case of a built-in thermostat, it is manufactured on or after July 1, 2027.

Testing Standard
A line voltage thermostat complies with the energy efficiency standard when tested in accordance with the applicable testing procedures established by CSA C828-19.
Energy efficiency regulations by province
Some provinces also have their own energy efficiency regulations for many of the federally regulated products – find out which ones!
Energy efficiency standard
The energy efficiency standard is set out in clause 4.4 of CSA C828-19, which is summarised in the table below.
| Equipment Class | Droop | Differential | Control Point Precision (avg temp) | Standard Error for Minimum Temperature, Average Temperature, and Maximum Temperature |
|---|---|---|---|---|
| Wall Mounted Thermostat | ≤ 1.5 °C | ≤ 0.50°C (±0.05°C) | 22 °C (±0.5°C) | ≤ 0.1 °C |
| Two Component Thermostat | ||||
| Built-in Thermostat |
