Cost per hour is based on using the heater on its highest setting as, following our testing, we think this is the setting you're more likely to use. Calculated using the unit price under the current energy price cap (24.5p/kwh). We're not able to show every retailer and cheaper prices may be available.

Heating performance based on how quickly the heater raised the temperature of the room in half an hour, and how evenly it heated the room.
