Batteries

Who knew that thermostats were powered by batteries? The thing is attached to my wall, I really thought it would have some kind of power supply. Nope. Batteries. And mine died. A few days ago. That means my heater hasn't kicked on in a few days. Luckily it hasn't been very cold lately. I'm thankful my brothers had some batteries I could steal. I'm thankful my heater is currently running! When I got it all plugged back in, it said it was 64 in my house. I like my house cold, but not that cold!!
