I broke down and turned on the heat today. I’m not sure why, but knowing when I turn the heat on each year is of interest to me.
- 2007: October 11 (inside temp: 63)
- 2006: September 21 (inside temp: 64)
- 2005: October 24 (inside temp: 55)
- 2004: October 5 (inside temp: 58)
- 2003: September 29 (inside temp: 58)
I’m not sure how useful it is to compare since this is now looking at two different houses, but whatever. Each year’s weather patterns change as well, so it doesn’t mean that much. Last week it got so warm we turned on the AC and now the heat’s on.
Another heating oddity–our new house as a high efficiency furnace. The previous owner told us it’s more efficient to set the furnace at whatever temperature you want and leave it there. Turning it down at night wastes energy because it takes more energy for the furnace to heat the house back up than it does to simply maintain the temperature. It has something to do with the furnace kicking into a higher burn. Seems odd to me. I can understand it if you turn it from 72 down to 62 at night, but what if you do something more gradual, say 70 down to 66? It just seems unnatural that turning the heat up is using less energy (it also makes having not one but two fireplaces seem kind of pointless).
Update: I asked a furnace guy this question and he said that’s ridiculous. Turn it down at night and save some energy.
