There is no fused spur next to combi boiler, i assume the boiler, clock and stat are wired to a wiring centre then straight to consumer unit, is this correct?? thanks
if cable goes under floor boards, that sugests boiler is upstairs. Or it can be ground floor floor?
If boiler is upstairs, have a look in the kitchen, sounds like the used the old power supply to water heater/cylinder supply
my boiler is wired back to the airing cupboard and connected into the honeywell wiring centre with a fused spur powering everything through the wiring centre.
The reason i asked if it was an upgrade, was the last one i seen as described , was wired to the cooker point, that they pinched from the old cylinder feed from the airing cupboard. Lol
