Hi, I'm looking for some help regarding a Creda storage heater (white meter). The model is 79047B, but when I searched for this on the Creda website it said that the code was not recognised. The unit was probably installed around 1991/92 when the flat was built. Firstly, let me make you aware that I'm not clued up on these things so you'll have to bear with me! I have two storage heaters in my flat, one in the living room and one in the hall, and last week the one in the hall stopped working. A similar problem happened a few years ago when both units stopped storing heat overnight and this was due to a stopclock in my electricity cupboard not working. This was replaced free of charge and the units have worked ok ever since. Two events happened just before the heater broke down - 1 - The trip switch for our kitchen triggered about this time. I reset it and everything worked fine. I don't think this is related in any way, but I noticed that someone made reference to this on a previous thread regarding storage heater problems. 2 - The air vent on the heater was covered for a short period of time. Do these type of units have internal trip switches that are activated to switch the heater off if the vent is blocked? If so, how easy is it to reset the switch? Or do you have to replace a part? I've altered the thermostat on the unit and also turned it off and on at the wall, but no change. I've also checked the mains supply and the electricity meter and everything is on and seems fine. Any suggestions would be greatly appreciated.
