Why is my Dimplex Heater too cold?
- TTimothy GarciaAug 6, 2025
Several factors can cause your Dimplex heater to feel too cold. There may have been a power interruption during the off-peak period, affecting the heater's charge. Ensure the off-peak circuit is working, the wall switch is on, and the fuse is okay. You can also try turning up the INPUT control, but note that it may take up to 24 hours to take effect. Alternatively, turn on the 'boost' function. If the heater was covered, the safety cut-out might have been activated, in which case you should contact Customer Services. Also, if you have an automatic heater, the room temperature can affect the charge taken.
