The winter of 12/13 was the first time I ever heated with wood 100%. An unusual thing happened in that I did not complain about the cold weather at all. I usually kept the thermostat at our old house at 68 degrees and now have no trouble keeping it at 74-75 degrees. When you have that good warm heat, it really recharges your core heat level and I noticed that I can stay outside longer. My wife reported the same thing. The only downside is that the air is so dry the my kids hands looked terrible and my skin was on the dry side. The humidifier on our air handler is literally from 1971. Looking into a new one but there were terrible expensive.
