    Personally... I wouldn't have done the work to the furnace considering its age and efficiency. There are furnaces on the market now that would run rings around an old unit like that. Of course all of that comes with a hefty price. I dont think there is anything you can do to upgrade the controls for the wood side of the unit. Even a new modern day woodfurnace contains a transformer, limit/control and a thermostat to control the servo on the damper. There is one furnace that has a computer that controls the blower based on temperatures in the plenum, but thats for one model only. You can wire a digital thermostat to the unit, and maybe a multi-speed direct drive blower but thats all I can think of as far as upgrading.

    Well i looked at some new ones and I couldn' t swing the cost this year thats why I went to extremes essentially overhauling the existing, I insulated the hell out of the plenum and sealed up all the duct work, she's working better than I ever remember, quieter too, with the new bearings and all. Thanks for the info...
