So, I should preface this by saying that I live in Northern CA, so I realize that this might seem a bit trivial coming from me, but I am wondering when other people turn on their heating? I keep mine set to go off when it gets down to 60 degrees inside. Today when I came home, it was 62 degrees indoors -- it was warmer outside! I happen to live in a lovely old house that somehow does a great job of being sweltering all summer and then being freezing all winter. It seems like just the other day I was sweating and eating ice cubes to stay cool (no ac) and now I am bundling up and making tea to stay warm! It just seems to early to turn on the heat. What is your heat threshold?
