Just to check - I have a system boiler which provides central heating
and heats a hot water cylinder.

The programmer is off and there seems to be no power to the boiler
(problems with downstairs lighting circuit).

So does all the power to the system flow from one connection i.e. the
boiler takes its power directly from the programmer or are the two
independantly powered?

If it is all one feed then I can find where the power goes in and
connect in temporarily from a ring main to get the CH working.


If its been done to spec ALL the CH/HW electrics will be on ONE switched
fused spur. USUALLY off a 13A ring or a completely separate 6A circuit.


IF......:-)

If the boiler and programmer are powered independantly (and both off the
downstairs lighting circuit) then that is more of a challenge.

I am assuming the pump is either powered off the same circuit or off a
seperate 13 amp feed.
Either way I might be able to make a temporary repair.

Moral - even if it is broke don't try to fix it.
