I tend to avoid the yearly debate, but I did think about your scenario for
a while, and I came to the conclusion that it's about the same as a timer.
Consider this situation... You get a string of non-flying days where it's
30 deg at night, and 45 deg during the day. Your cube will turn the
heater on every night, and let it cool during the day. You're effectively
getting the same situation that you're trying to avoid with the timer. I
figure that turning my heater on once a week (early Saturday morning) in
anticipation of flying on Saturday will probably be a reasonable
compromise.

True. Your solution probably makes sense for where you live. Your
temperature scenario only occurs around here during the fall and spring --
and I don't even have the cube plugged in yet. (Of course, right now the
plane is down, having the interior panels re-done over in Clinton -- so it's
in a heated hangar!)

In another few weeks, however, the temperatures will fall below 40, and
mostly stay there for the next 10 weeks or so. From that point on, the
heater will be on basically 24/7.

But, if we get one of those rare winter warm ups, where it jumps into the
40s or 50s, the cube takes care of shutting off the heat.
