I wrote some time back re the 2 rads i fit in conservatory, still nt working,
all the rest in house are fine - the one i teed of from is hot but cannot get flow to both of the new ones i have had a plumber in- changed pump didnt work then changed back, turned off all rads in house except one teed off from to try and push water through - nothing except aired.
put hose on drain end and opened - water flow very good from tank in loft.
its in new pipe 10mm plastic with no apparent blockages.
Plumber recommends leaving heating on all night to try "and drag " the hot through, he says there could be air traped ( i cannot see it been that )
PLEASE HELP
