Electric stove heaters are made to resemble old fashioned wood burning stoves, but seek to better them by lessening the pollution and amount of work it takes to maintain them. Plugged into a wall output, they are much like any heater, but display images of flickering flames to create a glowing ambiance. A quality electric stove heater should be able to emit enough heat to effectively warm a small space while remaining cool to the touch.
Although most of these units can be surprisingly heavy on your utility bill if used constantly, they should ideally be efficient enough to regularly provide supplemental heat to a space. Electric stove heaters are generally quite sparse when it comes to features, with simple controls to change the temperature and flame size. However, some include a remote control and the Dimplex TDS8515TB even includes built-in filtration to improve air quality. How realistic the flames look is subjective, but the best electric stove heaters in 2022 should be able to effectively provide supplemental heat to a room, while having simple controls and an attractive design.
