CH pipes and water pipe run.

[robbie77]

Hi

I am linking up CH pipes for UF heating and running hot and cold water into extension.
I have them all heading to the same corner and don't want them too close. The water pipes are below CH pipes and need to run above them to get to bathroom. The only thing I can think off is to aim the CH pipes out at an angle in the corner and have the water pipes go behind them.
Does that sound OK? I don't think I have explained well hopefully picture will help!?
Thanks

You need to keep the cold water far away from heating or hot water pipes. Or insulate them.

Otherwise you will find warm or hot water coming out of your cold taps

What about a couple of these on the Ch pipes?

So If I put the cold water on the bottom clips and the hot the one above it is this far too close? I thought with heat rising and all the cold on the bottom would be best. I could route the water pipes above the CH but thought this a bad idea also.

Good idea and that's the way you should do in some cases. But don't surround with heat pipes. It will p¡ss you off.

Do you think its worth cutting and extending the CH pipes so that they are moved up a few inches away from the water pipes toward the wall plate timber? I am not sure how much of an issue its going to be,

Just insulate the cold pipe as a minimum , preferably all of them so the cold doesn't get warm

I might be talking rubbish but could Legionnaires breed in the cold pipe if it heated up enough?
