Will it work to use an old airconditioner for a shop heater and also double as overheat protection. I have three 25 plus year old airconditioners ( the big 110v). It would be a raidiator with a fan to push air. Is it possible for one or both?

The problem is that you are having to run both the circulator motor AND the fan motor. In case of a power failure, I want the lowest possible power draw in order to run the overheat loop with an inverter. I don't plan on running my EKO during power failures as I have other means for heating but I need to have a place for the heat to go if the power drops out with a full load of fuel. I'm in the process of building my unpressurized storage tank and plan on putting a copper coil which I had laying around from another project, in the bottom of the tank.

No to dissuade you from building a better heat sink but to help prevent overheat with a full load and a power outage (as long as you are there so you can do something about it) try closing your secondary air supply completely off as this will (should any how if your secondaries seal well) close off the air supply to the fuel and if not extinguish the fire it should choke it's ability to run away. Another secondary precaution is to also close the shutter on your fan housing though the position of your primary air inlets will determine if this would really help or not.

a thought
The draft fan on my boiler has a cover with gasket on it's intake... when the aquastat relay turns on the blower, power is supplied to the electromagnet and pulls the cover off the blower intake, when power is off (or fails) it automatically chokes all incoming air.
