I had my Quantum switched off for the summer and now not releasing heat straight away. Why?

After switching your heater back on if switched off for a period of time the heater can take up to 2-3 days to take their calculations, take a charge and start working normally.

This is not a fault and is normal operation.

If the heater still doesn't take a charge after 2-3 days then please check-

  • Supply has been confirmed to the heater.
  • Heater is not covered or obstructed as per the clearances set in the manual.
  • Time & date settings & timer modes set up correctly - refer to relevant series user manual which can be found via https://www.dimplex.co.uk/support/guides when entering your model details. Ie QM100.
  • Temperature on User interface has been set higher than the current room temperature 

If all checks confirmed and still not taking a charge releasing heat see  link below -
