[QUOTE="John Roberts, post: 113563, member: 126"] Re: Incandescent Lightbulb "ban" 2014 While crude, it seems co-locating cold water inlet pipes and warm drain water outlet plumbing with thermal coupling between the two over some span underneath the house (like in a crawl space) might make a cheap thermal recapture system. Not as effective as a proper heat exchanger but might have some benefit for nominal cost. Probably need metal plumbing for this heat exchange span. JR [/QUOTE]
