Dimplex Storage Radiators

[eddieboy]

My parents have got storage rads and a few don't work properly, despite the knob being on the lowest setting they pump out maximum heat. What is the part that has failed and where can I get them from?
Would it be cost effective to replace all of the rads as they are really old? I'm not sure if the newer ones are more efficient than the older models.

Are they on Economy 7 ... Off Peak supply?
Have you confirmed this supply is switching at the correct times?

Thanks for the quick reply.
Yes they are E7 and are switching on / off at correct times. It's just that 2 or 3 of them are getting too hot to touch even with being on the lowest setting.

You need to replace the charge controllers, these regulate the input. Make sure you get the right model number.

If the heaters are emitting high levels of heat then it sounds like the outlet plate has stuck open or the insulation on the heaters has broken down badly.

If the heaters continue to output heat during the whole day then they are being powered during the day (there is sometimes a boost power switch that can operate the heaters in the day).

Parts for such heaters can normally be obtained from website such as spares4U, spares2you, buyspares, Espares etc.

Taking an extremely wild stab of a guess, maybe, possibly, could be the thermostatic switch assembly??? lol!!
