I actually sat in on a free webinar by him on the subject of Renewable Hydronic Heating. It was pretty good... but somewhat of a product presentation. Some equations were presented that were very valuable, I think his target audience was contractors & installers.
In my opinion, John Siegenthaler is very intelligent, very well informed, but I think that he is constrained by local codes and building and trade practices to get out on the cutting edge (European standards). I understand, because he needs to be relevant to the current building community, otherwise no one would listen to him. I don't fault him... he has a job to do and he does it very well. But I don't think that his word is the last word in efficiency.
I asked him some questions in the webinar about ultra high efficiency, I even used the "Low-Exergy" word... he answered a few questions and finally quit because I was going too far off script.
He did say that he was writing a book on Low-Temperature Heating. I'll be interested to see what he comes up with.
