Diagrams of a heating system?

[Hightowermark]

Hi i'm looking for a heating diagram for a radiator system off a combi boiler, i've done a search but all diagrams are based on cold tanks etc.

Just looking what'sthe best lay out aswel as 22mm pipes.

Can anyone offer any help.

Wickes do free leaflets but as a rough guide you should come off the boiler in 22 mm and aim to feed rads off it with branches for optimum flow.
You can branch off the 22 and feed up to 3 rads in 15 mm.

I take it that Wicks don't do load calculations for the pipe work. Rough guide 8kw 15mm pipe 19 kw 22mm pipe and 30 kw 28mm then you need to know the loads and outputs of your rooms/rads requirements
