Hi To start off with I'm not a plumber. I just had a new bolier and central heating system installed. I know this pipe work will be hidden but the picture below shows part of the instalation which to me just dont look right. Is using copper & what I assume is Polybutylene ok. The new heating system all works but I thought it would be all copper and a lot neater than this. What do you guys think or do you have any comments about the pipe work you see, would you be happy if you just paid £6000 and see part of the system looking like this? Many Thanks for any advice or help offered.
