Just had my garage converted. Plumber put two radiators in conversion. Ever since the living room next door, which has water underfloor heating installed, has stopped working- now it is freezing cold. No sign of heating at all. other ground floor rooms underfloor heating working but not living room.
Why could this be?

No success. Still freezing. Can feel warmth in hall but not in living room. Unipipe underfloor system. One of the pipes in hall cupboard is cold assuming must be living room!
Will pay anyone who can warm up my living room! It's going to be a cold Xmas.

Try turning off the valves to the garage radiators and see if the heat is forced around the living room. If it does then open the garage rad valves a little at a time to balance the system. (don't forget to close just the one valve on each radiator)
