In response to Re: adding extra radiators
As you have discovered, adding radiators is more than just putting in some more pipe. There are flows that have to be balanced and flow pressures that have to be considered. You really need a heating person. Just putting in tees will probably not help at all.

: we have a 4 year old house with a conventional central heating system .
: We have had a room added and want to add two raditors aprox ( 3500 btu's ) each .
: The system uses 22mm hot and cold loop , with each individual radiator being fed from a 10mm micro borepipe of the loop
: We have plumbed two rads in from the nearest rad avaible some 4 meters away in 10mm pipe but can only get one rad hot at any time , there is no air in the system , what is the solution , as different people have all sorts of ideas ,
: The only one that sounded likely was to T of the 22mm main in 15 mm pipe as they said there wasnt enough flow in a 10mm pipe as the bore is only 6 mm internal .
