start looking under the floor near boiler and cylinder,in ya fireplace and near there under the floor again,or you could trace back the cables from the wiring centre but this is very awkward to do
are you sure you have one it may be a gravity system
good luck geezer

cheers for that mate.
it is a gravity fed system, i should have said its not a combi.
well, its not above or below the boiler, or in the cupboard under it. not in the airing cupboard by the cylinder.
all the floors on ground level are concrete, and i dont think its in the firsplace as its very small, and from what i can see is just the gubbins for the fire...
ill keep looking
