Hey everyone,
Am working on a hideaway y plan system boiler, customer said that the hot water works and the radiators works upstairs but none of the rads work downstairs. At first I assumed it was the pump I discovered that the pump was working, I then assumed it was air lock so I turned off all the rads that were working and left the downstairs rads which started heating up but I found out that the return pipe on the radiator was hot but the flow was cold. I then assumed that the pipes may be blocked. i have also balance the rads but still no joy.
My question is
if the flow pipe is cold on the radiator and the return hot does that mean the system is blocked somewhere.
what would u do differently.
