Building a Manifold for my Central Heating.

[Venomgrass]

Hey Everyone, Could someone please advise me on how to make my manifold.

I've just had my 45kw biomass boiler installed. All the pipework for the boiler leading to the main flow and return pipe is 35mm.

My radiators which I plumbed in myself consists of 25 radiators coming to a total BTU of 114,000BTU. The radiators are plumbed into 6 separate zones each with it's own feed and return. The dimensions of my zones; two are in 22mm pipe and the other four are in 15mm.

Do I need to keep my manifold in 35mm, which tees off into the 22mm and 15mm zones, or can I drop down to 28mm to make things easier by cheaper fittings, and the option of plastic.


Thanks.
