Sitting in the ultra-quiet coolness of a 2 yr old Mitsu Hyper Heat unit right now. They really are as good as everyone says. They are best when set to a temp and left at that temp. I don't think you get much advantage using a setback, but I could be wrong. They use very little electricity once they reach the set temp as the fans slow way down and just maintain that temp. I use for heat as soon as temps are above mid 30's since oil is still cheap for colder temps and the hyper heat units go through a long cycle (maybe 30 minutes) doing something to prevent ice build up, I believe. During that time, there is no heat output.
