Hello,

there is a timer downstairs and it clicks when I turn it round. The
boiler does heat the hot water but it doesn't make the house warm.
I do think that it is an immersion heater in there somewhere which
heats up and does something. When it is just set to heat water, then we
do get nice piping hot water, but when it is set to hot water and
heating then only hot water, no heat.


OK kiddo,. we are getting warm (as it were).


Cam you confirm that the radiators get hot when you 'override' or is it
just the hot water.

It does sound like you have a twin motorised valve setup, and as per
normal, after the summer, the heating one is bloody stuck shut.

If so then you wouldn't get heating on ANY setting.

If so, its a relatively simple fix if you are relatively handy. If not
say so and we will yell at you to get a plumber in :-)


Wow, what an amazing group!!

Thanks

Newbie

But we have a very old (don't know how old) central heating system
which only warms up if I switch on the electrical override switch. (the
one for the emergency hot water?)

Without this switched on, nothing happens, but with it, the house gets
nice and toasty. The trouble is, isn't this a much more expensive way
of doing things?
Could it be that he's just turning on the electric immersion heater -
ie the boiler (gas maybe?) is not working at all? ie, would the
immersion heater possibly heat the house, if the pump was running?
