Well I had been waiting on the edge of my seat for my heating bill to come in December and it hit last night: I am disappointed to say the least. We had a dogsitter at the house using the natural gas for a long Thanksgiving weekend, but that was it. Otherwise I've been home loading the stove two times a day and I ~thought~ that heating bill would of been flatlined like November as I can't recall the heat kicking on but once....honest....and I watch the three thermostats in the house like a hawk. From heating with wood I now know my new-to-me 1957 home is poorly insulated, windows are crap, etc., but if I never noticed the heat kicking on, what gives? The only draws on Natural Gas is the cooking stove (should not of changed significantly) and the water heat (in the basement as it's always been, and just my wife and I using it.) It's colder this same time vs. last year and there are 2 more days in the billing cycle vs. last year, but only a 55% reduction in the bill?! So what gives?! Argh, so disappointed for all this work an $ invested.
