Best convector heaters
Convector heaters resemble freestanding radiators, heating up the room by producing convection currents.
We've tested more than 40 electric heaters over several years, with convector heaters from DeLonghi, Russell Hobbs and more.
Our testing has found the best convector heaters don't need to come with hefty price tags. In fact, some of the best cheap electric heaters we've tested are convector heaters.
We've found five convector heaters impressive enough to get our Best Buy recommendation, three of which also get our Great Value recommendation.
Why you can trust us to reveal the very best convector heaters: Which? is a not for profit organisation and has been testing products and calling out rogue businesses for almost 70 years.
In an increasingly chaotic world, filled with so-called 'experts', it's good to know that brands still can't buy their way onto our testing or influence what we write. We buy every product we test and we'll tell you the worst as well as the best convector heaters.
Discover our rundown of the best convector heaters and how much each costs to run below.

Dates tested: August 2024, December 2023, August 2023, November 2022. Pricing and availability last checked May 2025. We are not able to show every retailer and cheaper prices may be available.
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 (24.86p/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.
