Natalie recently found this article explaining why programmable thermostats save you money, and I thought I would share it because it is so useful. It’s apparently a confusing topic to most, and I’ve already gotten into several arguments about it. Actually, I remember thinking as a child that keeping the temperature constant in a house was more efficient than having it fluctuate a lot by turning the heat down when you left or went to sleep. After taking classes in heat transfer and control systems in college, it’s obvious to me that I was wrong, but most people have no reason to take such classes. Here’s a good article summarizing it in layman’s terms instead:
