So we pretty much are putting the wood furnace away for the summer. The temp changes are to crazy where we light a fire and its 80 in the house so we are just using the LP furnace right now. Also learned our Tstat on the Englander 28-3500 is bad. We are one season down on this indoor furnace thing. I grew up with a home built outside hot air furnace that we just shoved what ever we wanted into it and never maintained anything other than the blowers. So need some advice. What would be some good ways to get this ready for next winter? Any way to improve the furnace? What to check when cleaning? .
