We have wood heat, with a central forced air wood burning furnace in the basement. The thermastat controls the combustion on the furnace and works very well. Isn't a simple on/off but anticipates load or something. Also is designed to allow gravity air circulation through the ductwork when the fan isn't running.
We usually set it at 66 to 68, and down to 60-62 at night. If it is sunny out, the sunroom/greenhouse on the south side of the living room keeps the house adequately warm, so the furnace produces little heat, so we usually have a good bed of coals when we get home after being out for 8 to 11 hours, or overnight. 66 is warm enough if it isn't drafty, and that is the big and noticable result of improving insulation, weatherstripping, and windows in our old farmhouse--much more comfortable, and costs less to heat.
