Is it possible that FHA needs to up date handbook?
I am not talking "Wood Burning Stove" I am talking Wood Fired heating systems, just as I could be talking about a "Coal Fired" or Coak Fired" heating system.
You have the same risk of running out of fuel with an LP system or oil system as you would with a wood, coal or coak system.
With an LP, Oil Natural Gas system you need electric to run with a wood fired system you don't need electric to run if it is a wood fired furance in the basement. Poor weather you can still heat if the power goes out.
I agree with Ray........but what is "coak?" Also, with a wood fired burner in the basement are you speaking of a gravity system? Otherwise what "pushes" the heated air from the basement through the ducting and into each room? And, are you sending air drawn from the basement and heated in the burner or is there a return air system?
