How do I add extra radiators to an existing central heating system?
I need to add two extra radiators [down stairs] to the heating system. I have checked the boilers btu output this is ok.At present all pipe work [10mm] to each radiator [down stairs] comes from manifolds connected to 18mm pipes close to the storage tanks and pump which is up stairs
Is it possible to connect these new radiators[10mm] pipes to the 18mm pipes close to the boiler which is downstairs or should they be conected to pipewok by the c/h pump
if you tee into ten mm pipes you will get more trouble than this is worth shouldnt tee into anything less than 15 mm

its always best to tie in at/near manifolds though you will get away with tee-ing in to 10mm that runs to existing rads, you will then need to adjust rad valves to balance heat
