Are room heaters energy efficient?

The majority of our finds are portable room heaters, or space heaters as they're often called, which are ideal if you're looking for a quick blast of heat for a short period of time. According to the Centre of Sustainable Energy, electric room heaters are 100% efficient as all of the electricity used is turned into heat. However, they're not the most cost-effective way to heat your whole home as they tend to use a lot of electricity.

So it's all about finding the right balance when heating your home, and it's best to use an electric room heater alongside your central heating system, taking room size and duration of heating time into consideration.

The energy efficient heaters in our round-up include features such as thermostats, timers and temperature regulating tech to help you control the device's energy consumption. We've also included personal heaters you can place on your desk, as well as a wall-mounted device. So take a browse, and find a suitable match for your home set-up.

Pop on for an hour as you're getting ready for work and make a dark, frosty morning more bearable.
