Thanks for all your replys and advice. I will let you know if this gets resolved. Just trying to source a engineer now. At least i have a rough idea what it may be.

Thanks for all your replies. I understand that diagnosing a fault on a boiler without seeing it isn’t simple at all. I just thought with the symptoms I had it may point to something simple. I will try to get an engineer to come and have a look, but trying to find a good one in our area...

Sorry Dangermouse, I have checked and the valves I have are just the standard ones which you can isolate the radiator not the Thermostatic ones. Sorry. I really appreciate all your help on this matter.

All the rads in the house have the valves on which you can turn off the raditor.

Yes the HW is fine it, i just this problem when the CH is on. This subject is a bit new to me, what is a system bypass?

Thanks for the quick reply. Is the pump and easy part to get hold of and can it be fitted yourself or do you have to be corgi registered.

Dangermouse thanks for the reply. You dont think it is just a simple part that needs replacing then?
