Evening to all at TP. Here's one for the local sparkies.
I've just had my two years old gas multipoint heater in the kitchen freshly serviced by an engineer and he noticed there is a reverse polarity feed to it from the wall switch and needs to be corrected - and for that I'd have to get hold of an electrician. But for now, the engineer quickly checked the electric supply on a couple of wall sockets around the house and all checked out fine and the heater itself will carry on working as normal anyway.
What's got me puzzled is this: I would have thought a reverse polarity feed to an appliance would cause the RCD unit to trip or worse still, a short circuit, but the engineer did say most modern multipoint heaters can take a reverse polarity feed, just that it'll stay "hot" even when switched off at the wall switch.
So, I'm hoping it'll be an easy fix by unscrewing the wall switch (which has it's own fuse) and swapping the wires around. I certainly won't be doing it myself as I do not get well with electrics at all - I don't think anyone are when in contact with 240 volts!
PS: This is here at the UK, if that is of any help to anyone.
