Nothing wrong with 10mm to rads......as long as the runs ain't really long and the rad isn't a massive double! Do tonnes of system with 10mm. Although 15mm is better....a well protected and flushed 10mm system is perfectly fine.

Thanks for reply.
If I decided to go with 10mm pipe what would you recommend for max pipe runs? At the moment would be about 5m flow and return (10m total) to manifold 3 x double rads are 2.2Kw the other 5 x rads are all small.

Thanks

10mm upstands to radiators always look poor, and get easily bashed out of shape. So please do the upstands in 15 mm and hide the 10mm in trunking.

He is dropping pipes inside walls,so take it to outlet behind radiator and sweep down into chrome 10mm push fit elbows (screwfix] ,no joints in walls, very neat, hardly see any pipe at all, and clear floor for easy cleaning.

Yes, we have run these successfully with 10mm. Ran 22mm above ceiling, the dropped to 15 for each pair which were on 10mm each.

This is the best method, very tidy, plus stops the missus from bashing the pipe with the hoover. It’s what I’ve had for the last 15 years, as long as it’s fit right and flushed right then dosed with the right amount of inhibitor.... happy days.
