For a lot of them it ain't even much "learning" to the proper running of it... the wall thermostat pretty much "runs" the thing. That is, if you go with one that uses a wall thermostat (which, would be my recommendation)... you can still run them manually when ya' choose to. Most of the "learning" is just how often and how much to load... and if my wife can pick it up... well... (somethings are just better left unsaid).I think I'm going to get an add on furnace and teach her how to run it properly. If its just adding wood and adjusting the damper's it shouldn't be too bad.
