I am wanting to extend the existing CH system to include 2 radiators being installed in an extension. The extension is accessed off a living area which currently has 2 radiators. Can I use a 22mm x 10mm speedfit manifold to split the flow pipe into 4, and then another to combine the 4 returns?
Also, if the existing flow and return is 15mm can I fit a reducing tee to increase the 15mm to 22mm and then include the manifold, or does the changes in diameters cause further problems?
Thanks in advance for any advice
