Why is my Dimplex XL6N Heater too cold?
- JJennifer VelezAug 1, 2025
If your Dimplex heater is too cold, it could be due to a few reasons. There might have been a power interruption affecting the charge, so check the off-peak circuit, wall switch, fuse, and consumer unit. Also, if you have an automatic (XLS) heater and the room is already warm, it won't take an unnecessary charge. In this case, turn the INPUT control down. You can also try turning up the INPUT control, but note that this may take up to 24 hours to take effect.
