Storage heater too hot?

    called out to see client with storage heater that is apparently not regulating its heat output correctly (too hot). i have no experience with servicing of these items but it appears the output is controlled by a flap valve and possibly some kind of bi-metallic spring? Anyone with any experience of these things having such faults? and are they easy enough to repair?

    It's normally the other way i.e not enough heat output. The bi-metalic strip is normally the culprit. It's just a case of gentle manipulation. Take the front cover of and ajust the dials whilst looking at the strip. See if it moves as it should in accordance with the settings. Hope this is of some help.

    The bi metallic strip controls the output from the heater, if it is getting too hot it may be the input stat that is faulty, stick your multimeter on ohms and check the stat is cutting in and out

    charge regulator is knackered ,thermal link will eventuallty melt or pop out , depending on make

    If the strip aint closing the vent when asked, the heater may be giving off too much heat. At least you have a few things to go on.

    Everyone seems to have overlooked the most common cause of Billing exceptions that I investigated whilst DNO employed!

    Timeswitch failiure in Off Peak mode! ;)


    This will be giving the Storage Heaters 24Hr Off Peak and hence overheat them!

    If it's just the one then obviously it won't be this, unless the unit in question has a failed thermostat too?

    the heater can stay on all day the regulator controls how hot it gets,it needs replacing

    Maybe if I had spent time investigating billing exceptions, whilst DNO employed, I would not have overlooked it :)

    The bi-metal strip has very little to do with overheating if at all . It will be the charge controller thermostat ,sometimes the contacts weld together ,separate and a quick file will prolong life for a while ,otherwise change charge controller.

    Watch out for overheating storage rads. There was a case not so long ago where the high temp caused break down of the insulation which generated CO which then killed someone.
