Overall score breakdown

Our overall score is comprised of two subscores:

Performance (70%)

Calculated on the heater’s ability to warm a room from 8°C to 13°C and from 8°C to 18°C, the evenness of the room heating and the thermostat’s performance. We test heaters in a special room fitted with 81 evenly placed temperature sensors. The temperature reading from the sensors enables us to create a 3-D map of the effect each heater has. We look at the time the units take to heat the room, the evenness of the room’s temperature, and how well the thermostats keep the room at an even temperature.

Ease of use (30%)

Assessed equally on: using the controls, the labelling of controls, the heater’s mobility, cord storage, and ease of cleaning.


Tilt test - while all heaters passed the standard’s requirement that they don’t topple over when inclined to 15° in any direction, any portable heater can be knocked over accidentally. So we put each heater on its side with the power on to see how long it took to turn off.

Drape test - we turned the heaters up to full temperature on full power and then draped a towel over each heater for 30 minutes. This test should trip the heater’s over-temperature safety switch.
