Hello I have drained system down just to have a clean, put a cleaner in last night and filled again. I have noticed the header is getting warm and the pipe obviously up to it. The pump is a Grundfoss Apha 2 and I have played with the various setting hoping to reduce energy. On auto it never adjusts right and ends up the boiler clicking off. I seem to have to run on one of the higher settings. When draining the water seemed pretty clear, but I have put an F3 in and will run for a few days, then drain again and run through before filling and using F1.
I think they may be an issue, the plumbing looks complicated or messy. I have done a diagram and attached some photos of the awful cupboard where its all housed. Let me have your thoughts on what could be causing and what to check. Thanks
