one pipe heating systems problem All aspects of plumbing questions and answers, help, tips and information

hi,I fitted 2 extra new radiators to a house (in different rooms)due to coldness and notice it is a one pipe heating system,I branched off the main ring for the flow to the new rad. and rejoined the mains for the return, does anyone know if this is right, or should I have joined the return pipe to the pipe i branched off from for the flow?
Because when ive put the heating on,only some pipes and some radiators are working. and i notice with the f and e tank in the loft the vent pipe has hot water flowing out. Can anyone help?!!?? :cry:

because the one pipe system works on the principle of a one way system
ie in one end out the other and on to the next radiator
i feel you have some were created a two way system
rather than teeing into the system you should have diverted the outlet pipe from the radiator before the new installation and this would be the feed for the new rad and then out from the new rad to the next rad along this the feed for that rad
dont foget as the water moves along the system it will get colder so the rad furthest away will be the coldest and by putting in two new rads this will effect the rads even more
good luck
