The AF150 efm automatic coal stoker furnace

Thank you. I am going to look into how much money it may cost to refab this s-20 stoker. I think getting it apart will be my biggest issue. I need to replace the feed tube, worm and grates. Any suggestions on the best way to get it apart?

You should be able to figure out the construction by viewing these pictures. The hardest part of the job might be removing the air tube that joins the stoker and pot. I used to use a torch and sliding hammer, but sometimes it came right out. The key is: how long was the assembly sitting in a damp area.

My father-in-law has mentioned to me that he wants a coal furnace. But, he never wants to fill a hopper with a bag of coal when he finally retires and gets too old for such things. Since the efm can be auger-fed from a coal bin, this might be the perfect coal furnace for him.

We live in Connecticut so no dealers are nearby. Has anyone bought one recently and know the cost?

Thanks!
