Adding 2 rads onto microbore system

[gates1979]

I want to add 2 new radiators onto my central heating. I have a combi boiler and all the pipework going to the rads is microbore so am i right in thinking there will be some sort of manifold somewhere upstairs where all the rads branch off and this is where i will need to attach my new pipework for my new rads thats if there is any spare ports on the manifold. If not can i t into the 22mm flow and return and add another manifold to take my new pipework, hope that makes sense 🙂

Yes as long as you can tee off the 22mm, dont tee off the 10mm.

then its just a case of balancing it up

You don't necessarily have to use a manifold for 2 rads. You can just tee into the F and R with 22x22x10 (or 8) tees. Ie, 2 tees on the F and 2 tees on the R.

Have you found a manifold? You may not have one. But you've got the right idea there.

Went to one a few weeks ago, they had teed a radiator off the 10mm and there was only one radiator coming on at a time. Funny but a waste of a radiator.
