Is 10mm pipe for radiators cutting corners

[Drew1000]

Hi,

 

I am about to run first fix piping for my radiators in a new build and was wondering if it makes much of a difference using 10mm pipe as opposed to 15mm.  As its a new build I have no restrictions in running the pipe but would be grateful for some advice from those with a lot more experience than I have.  Regards

No and 10mm Hep20 is dead easy to run - bring it out middle of the rad and use copper for the last bit if you want it to look nice

1950's house I live in had an 8mm copper system for 30 years. Radiator runs  supplied in parallel by a central manifold. No issues.
