[QUOTE="rprice11, post: 394048, member: 26350"] Thanks for the responses to this, it's great to know theres a community willing to help. Just an update on this. Today isolated the pump and turned the heating and boiler back on. then after about 2 minutes it sounded like a surge of water clunking through the pipes (i was listening in the airing cupboard. i had my finger on the pipe when the water went through it was so hot it burnt my finger but the heat was gone quicker than it came. after that the boiler stopped and now hot water. @dave2 - sorry to be dumb but i'm not overly sure which pipe is which when it comes to flow and return, and when you say the cistern do you mean the cylinder in the airing cupboard? @Prodave - How would I identify a loop? @do hudson - I had previous drained it about a month before, had a cracked radiator due to sludge so i drained the system down, took all rads off flushed them with a hose and refilled the system, this didnt cause any issues, i only had to drain the system again due to some leaky joints on the rads which needed some more ptfe tape and tightening. I've got some images of my airing cupboard but i cant find how to attach them from what i can see i've got no vents on any pipes. [/QUOTE]
