The motorised valve works ok as

1) I can see the lever move automatically when I select water &
heating, from water.
2) both rads and water are lukewarm.

Motorised valve is fairly new - it was replaced not so long ago because
I could not have hot water without the heating being on!

The pump is working ok as

1) When I select different speeds, I can hear and feel the pump running
at different speeds. I can also feel the water gushing up the pipes,
particulary when I change from low speed to fast.


Perhaps I could be wrong, I accept that new (or fairly new parts) can
go faulty at any time. Is there a better way of checking??

The motorised valve must be ok (Again I only replaced this less than 2
years ago).

Could you explain these statements. Why must the pump and motorised valve be
OK?

Christian.
