Slant the floors to aim at the auger & with luck I never have to touch the coal all year after the bin is full. I burn 800 gallonsof oil a year now, so I'm figuring 4 1/2 to 5 ton of coal should do the trick.
Beatle, Why do you prefer the AHS over the AA?
I like the AHS b/c it is a gravity feed. I'm looking at it like a hopper boiler. All other hopper style boilers need a stoker, the AHS does not.
Also, I think the AHS is insulated, but the AA is not. Could be warm in the room if using it to heat HW during the summer.
Here is the A-A with the Jacket & insulated Option The isulation is 2" Fiberglass wraped around the boiler the jackets covers it http://www.axeman-anderson.com/anthratube.html
