We have a second hand dimplex storage heater XT12. When first installed was working ok on level 2 for about a week, turned dial up to level 3 heater failed to heat up overnight this went on for 3 nights no heat. Last night left heater on again turned back down to level 2 as this worked previously,this morning heater was red hot and smelly. Can anyone explain the problem and what we can do to rectify it.
