The temperature dropped to negative 16 Fahrenheit last night, and in a draft old house like mine, even our new high efficiency furnace couldn’t keep up. We even had a small space heater going, and the house still was below 70.* Those 100 watt incandescent bulbs the government took at the force of a gun sure would have helped!
* My house is drafty, so while it may seem odd, the colder it gets outside, the warmer we need it to be inside to overcome the chilling effects of the drafts. E.g., when it’s in the 40s outside, it’s perfectly comfortable at 71 inside, but when it’s in the teens I need to push it up to 73 or 74 inside. As I re-side and insulate and replace some ancient windows, I hope that draft effect diminishes. But I dream of a house with radiant heat flooring, because that makes a huge difference in comfort levels, and am considering retrofitting radiant heat in my house, which is surely a better solution than stocking up on 100 watt incandescents (or using halogens) for warmth.
