Hi - I've got three radiators on three floors (rooms all on top of each other) which are stone cold. All other rads in the house work well. The pipe into the radiators is not hot andthere is no heat whatsoever in the rads. I had the system flushed through last year and all worked ok but this year there is no heat. Be grateful for any ideas as to how to fix.
Thanks very much Vix9
