I hope I can explain this without sounding like an idiot. I'm paying the bills right now and I finally decided I'd ask some people:
We went on a 10 day vacation last December. We turned off the hot water heater (ie VACATION setting), and we lowered the heat in our house to the recommended 55 degrees (we have a new build home and this was the recommended setting. we recently moved to Illinois from California where we would normally just turn off the heat completely). Normally we keep the house at 68 degrees 24 hours a day (I work nights from home). I expected to see a good dip in the natural gas bill for that month. After all, I figured we were using about 1/4 less gas - no cooking, no water heating, no laundry and 15 degrees lower in the house for 1/3 of the month. However, the bill came out and it was actually higher than the month previous. Granted, December here was colder than November so (i assume) the heat kicked on more frequently, but we weren't cooking nor heating water so at the very least it should have been the same as the month previous if not lower. We apparently used 25.5 more therms in Dec than in Nov.
I'm curious for people's input on that but my real question is this - what's the point of lowering the heat in the house? The way I understand heating to work is that once the temp in the house drops X degrees below the thermostat setting the heat kicks in to bring the house back to that temp. Let's say it's 1 degree outside and the thermostat is going to turn on the heat when the temp drops two degrees below it's setting. Wouldn't the same amount of gas be used whether the thermostat is set to 55 or 68? I mean, either way it has to raise the temp in the house by two degrees so how can going from 53 to 55 use less gas than 66-68?
