This is an on going problem with electric fireplace/stove type heaters of all types. Not just Dimplex. They are not designed to run for long periods of time and the heat output is not much more than a blower dryer. In any event, they take in cool air, heat it and send it back out. Over time, the heating element becomes clogged with dust, lint and/or pet air. So, they have to work harder to produce a sufficient amount of heat. Cleaning the heating element with a vacuum that has a hose and brush attachment may help. The heating element and blower are under the stove. See your Owners Manual on how to access it. Be sure to unplug the stove before trying to service/clean it.
