Hi,
Yesterday we had all the pipework for our central heating replaced, as we were having an issue with the rads downstairs not working (after a recent rad replacement and power flush).
When the guys left yesterday all the rads were working - we had full heat in all rads - boiling hot! We had the central heating on till around 10.30pm before shutting the system off.
However this morning, when the central came on, only the hallway rad was on, and it was barely hot. The rads for the dining room and the lounge were stone cold.
I dialed back the lockshields for the rads upstairs, as they were left fully on, and am confident they're nicely balanced as there's good heat coming out of them. The flow pipes into the rads upstairs are roasting hot.
The flow to the rad in the hallway is hot, not roasting, but hot. I've checked the pins on the TRVs on the two rads in the other rooms and they're pushing down/popping up ok i.e. not stuck. The lockshields on the rads downstairs are also fully open.
I checked the main flow pipe from the boiler to the heating downstairs - the pipe is boiling hot. But the return is cool to touch - not stone cold but not warm either.
I'm trying to get hold of the plumber but he's not answering, so will try again later.
In the meantime does anyone have any suggestions as to why, with new pipework, and with the rads working fine yesterday, they've suddenly stopped?
Any advice would be greatly appreciated!
