Hello All
would anyone be able to help me with a problem I am having on a system I've been working on.
The System comprises of a Glow worm BBU with pumped CH and Gravity DHW with a cylinder and two F and E tanks in the attic. All is well on the CH side pump is starting and boiler firing on demand. Recently I am told the DHW is only warm (which it is) and not as hot as it was. There has been no work carried out on the system recently. The boiler is firing in DHW mode and the flow and return to the cylinder are getting hot. There is no air in the system as I cracked the nut on the cylinder flow connection plenty of water but again only warm (judging by the heat off the flow pipe) I expected to get burnt but didn't. Upstairs rads are getting hot which i'd expect and there seems to be no circulation problems for this reason I have not tried kettling the boiler (should I?). The electric immersion has been disconnected so I am unable to check if that works as it should. F and E tanks seem fine and the cylinder is full of water. Haven't had a huge amount of experience working on these systems so any help whatsoever would be appreciated.
Thanks in advance
Brian
