UVC In The Future

[Onoff]

If planning on fitting a UVC later (my later ) then where does the cold feed to a bath come from? For that matter the cold feed to showers.

 

My simple logic says if you're planning a UVC and everything (hot & cold) will be at mains pressure (after any PRV) then the cold feed to the bath (what I'm doing now) could just be tapped off the mains incoming at the first convenient point. Something tells me this is wrong and there's a specific connection at the UVC for cold.

 

As it stands today the quickest way forward is hot from the hot water cylinder and cold from the CWS. I have running close by though the incoming mains and wondered if that was an option.

 

One worry is that if I go mains on the cold and take hot from the hot water cylinder there'll be issues at the mixer taps.

 

 

Maybe haven't explained that the best! I want "drinking" water at the sink. Is that any different if it comes via the "cold" at the UVC?

 

Cheers
