Thanks for you response. Concerning your first question, take a quick look at the standard http://www.ahrinet.org/ARI/util/showdoc.aspx?doc=1198 and you'll see that entering water temperature is required to be between 35°F - 80°F. This is not the delta-T. It doesn't make any sense and I'm wondering why the standard was written this way.
Regards
Ian
