First fixing new build in copper

Would you recommend against this?

No, and use the hair felt tip mentioned above.

Thanks so you would do one notch for all 4 pipes. I was just worried about heat transfer to he cold water pipe

 

[cross thread]

one notch for all four ,as said wrap some felt to stop noise,check regs on notch position depth etc

 

[Riley26]

Thanks and obliviously run the heating next to each other in the notch then the hot then cold so it furthest away from the heating? I guess you only need to clip the hot and cold pipework?

 

[Riley26]

If you need a notch to take 22mm pipe at what depth would you set a circular saw at to cut the notch say 25mm?

 

[Riley26]

Will heat transfer to the cold pipe not be a problem then?

If you want to do it properly, and there is sufficient space, then I think the answer is obvious.

Most people dont like drinking lukewarm water.

Always the legionella risk too but I think this is a bit overstated in a typical domestic application.

So one notch for all is acceptable, cold furthest from heating and hot pipe? prefer plastic were this is not an issue
