I decided that it was warm enough in the house when I went to bed last night, so I didn't light the wood furnace. I figured it wouldn't get too cold in the house and that I'd start the fire when I get up at 5AM. I set the t-stat at 64 and went to bed. When I woke up, the house seemed a little colder than what I expected. Sure enough, temp was at about 61-62. I turned the t-stat to 70 and headed to the basement to see what was going on. The gas furnace was making some kind of sound, but it sure wasn't the combustor kicking in. So, looks like I'm on wood only for a while. Glad I found this out now as we are heading to Florida for a week at the end of this month.
