Electric Towel Rail Concerns in Bathroom.

Hello All,

I recently removed a faulty electrical towel rail from a bathroom. The control panel was not working properly. The thing did not heat at all. It had a label on it saying Kingfisher International. Model.DD3LU-500a. Rated IP24. "Double insulated" with the square within a square logo. It had a 2 core flex. No C.P.C. That conerned me. How can a liquid filled heated towel rail not need earthing?


I believe that Fix Screw sells the same model.

  • Why should it not be double / reinforced insulation inside ? - All it needs is the element to be coated with a further layer of something, after the metal jacketed ceramic coated Nicrome, so a single fault cannot make the case live.

    Probably a good choice for PME houses...

    Problem may be that if the label is lost, you cannot be sure.

    Mike, most electric towel rails that I come across are earthed. Years ago they were oil filled where oil is a good insulator electrically. Nowadays to save money many are water filled, perhaps with an anti corrosion inhibitor. There is more of a chance of the thing becoming live due to an internal fault in my opinion. Also is IP24 good enough for a bathroom electrical appliance?

  • All depends on the internal construction   a simple mineral tube  'cooker element' type heater screwed into the metal pipe would I agree require a CPC. (and most are a bit like that)

    But if the construction is such that a single fault in the element or its mounting cannot make the case live, then it would be  OK.   I can imagine insulating bushes and a coating of the element being enough to do this.

    IP 24 - so  the 4 tells me it is spray proof from all angles, and the 2 says fingers cannot get to anything dangerous. I must say I would  expect '44 personally - it is quite hard to make something 24 but it is not prohibited by regs.
