Me too, I favor 65-70 meself, however, the vast majority of homes are
heated to between 70 and 75. However, if you take 70 degrees, that
gives you a 6% reduction in required btus with a zero degree day
outside. Not much on the scale of things. Particularly given that
the cited systems are capable of providing 12% of the required btus
for nicks system and 5% for morriss'.
