15mm from the boiler to 22mm into the bath

simon_t · 8 Oct 2006

Hi,

Looking at my bath it has 22mm going to the taps but only 15mm comes out of the boiler.

I was going to tee off the hot water supply to feed the bath and noticed this. Will it make any difference if I use 15mm then step up to 22mm for the bath taps? At some point the 15mm must change to 22mm under the floors or will the point at which this transition happens be important. I can't see why but then I'm no expert.

Coming from a combi 15mm is fine. Convert AT the tap if you like.
