This is an updated version of the product training course introduced by Supply House Times in 1979, authored by Don Arnold.
This month's College of Product Knowledge is excerpted from a chapter on radiant heat in Dan Holohan's book titled, "How Come? Hydronic heating questions we've been asking for 100 years (with straight answers!)" The book can be ordered from Dan's web site, www.heatinghelp.com. Click on "Books & More" in the left-hand column.
