The inlet feed to each radiator is fed from CH pipe and outlet from each radiator feeds back into same CH pipe. CH pipe returns to boiler after feeding existing 7 x radiators.
Does this make sense?
(Maybe I've got it all wrong....)

I am replacing an 15yr old + boiler and have a single pipe CH system. I also wish to add 3 x rads to converted attic.
Should my single pipe system be replaced with 2 x pipe system?
Also which boiler......
Any advice would be a start...
