Hope it's permissible to request some input here...
I live in a rented flat in London. We have two floors, ground and 1st, with radiator heating. The boiler is working fine (I believe) and we have plenty of hot water (radiator temp set at and hold at 73C). Four rads on the 1st floor are merrily putting out plenty of heat. Three of those four have TRVs on them, the other is "normal/manual" valve. On the ground floor we have two rads. One is TRV, the other is manual. The boiler is also on the ground floor.
We have always had issues with the rad in the dining room (manual). Until we turned the system down to leave for Xmas, the rad in the living room seemed fine. When I returned from Xmas, neither of the two were working. Again, 1st floor all fine. I called in the property agent's plumber yesterday, who indicated he adjusted one rad. Unfortunately I was at work so I don't know what exactly he did. When I got home, both rads were working.
This morning, once again, neither are working, and the air temp on ground floor is 14C (upstairs probably >20C). I can feel that the hot water line-in on both is cold. On the one in the living room, I can feel that it is at least warm about 7-8 ft from the rad, gradually growing cooler. I cannot do the same check for the one in the dining room as the line runs under the floor.
The valves on both are wide open (TRV on dining room is set to max/6). All I can guess is that something is preventing hot water from entering these rads. Obviously what the plumber did yesterday worked, but only temporarily.
What could this issue be caused by?
