I have moved into a property that provides a Dimplex storage heater to provide heating in the main room except I am having problems heating the room. The heater is made up of 2 switches on the wall and a single dial on top with numbers ranging from 1 (cooler) to 7 (warmer). It also has a convector. Being new to storage heating I am not sure how it works. What switches need to be on/off (during the day/night), what setting the dial should be on (day/night) and when should I use/not use the convector. Any help to heat my room and beat the cold much appreciated.
