The ease of use score is based on our assessment of the controls, stability, how easy it is to move the heater around the room, and how easy it is to clean.

Our priority is testing the models you'll see in stores and major online retailers. To do this, we check current market data to see what's most popular. We'll also test models that a lot of members have requested.

Testing electric heaters requires a very specific laboratory. While CHOICE does have high quality thermal laboratories, we don't have a lab suited to electric heater testing. So when we review electric heaters, we send them to an accredited external lab, which tests them to a program we've specified.

We rate the heaters we test based on heating performance, safety, energy efficiency and ease of use. Using our ratings, you should be able to work out the model that's best for your home.

Unlike other product review sites, we don't accept free test models from manufacturers. This allows us to be independent and review without interference. Instead, we buy products anonymously from a variety of retailers, then bring them into our labs. This means we get what you'd get, and can be sure the model has not been potentially 'tweaked' for better performance.
