John called me one day a long time ago and asked if I would look at a couple problems he was having with the heating system in the place where he worked.
I’m in the last 20 months of doing seminars and that has me reflecting on the places I’ve been and the sometimes strange and always wonderful things I’ve seen when it comes to heating.
I love the odd-numbered years because they contain ISH Frankfurt. This year was my 12th consecutive visit to that enormous hydronic feast. Which is not to say ISH is only about hydronics.
