In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I have had a few people recently ask me what books they should have for hydronic training and reference . Fact is, when I think of it I could use them too because every time I begin to think I'm a pretty smart guy, something, well, comes up;) . So...If you were to suggest a reading and reference library of say 5 books, what would they be?
