That's the trouble; this time of year you can get a 30-, even sometimes 40-degree swing on a sunny day. :hotsun:
:-k So what should govern shutting down, for those of us who do? The high? The low? The mean? If any of these, what should the number be?
Or is it just when you either run out of fuel or go away for a few days?
(I guess I'm a little slow to light and slow to shut down; I'm looking at when lows reach 40 and above on average. Then I'll be able to limit the elec baseboard for the most part to taking the chill off in the morning.)
