Proposed Combi Central Heating System

[biggerhammer]

Hi Guys,

I've cobbled together a diagram of how I'm intending to pipe a central heating system. The main flow and returns will be piped in 22mm plastic with 15mm spurs off to the rads, switching to copper for a better finish. I'm intending to run the flow and return runs under the floorboards upstairs.

I've left the DHW pipes off as these are already plumbed in.

Does this look sensible? Will layout induce enough flow through the centre radiators?? I want to plumb them in Parallel as much as possible so I can use TRV's.

Nice as in pretty or nice as in it'll perform adequately as a central heating system to heat my house . . . ?

At the moment, nice as in pretty. Altering the 2 rads to the right of the boiler so that they aren't daisy-chained, and have their own seperate feeds and returns, should change the situation to performing adequately.
