摘要

Ish Frankfurt is where you go to see the absolute latest in heating and plumbing technology. It's the trade show that introduced Americans to products such as condensing boilers and press-fit PEX systems. With that in mind, CONTRACTOR in March went to ISH in Germany to look for products on the leading edge, products so far out that we might see them here in a couple years, or maybe not at all. Perhaps the most far-out product was a resi- dential fuel cell.
