I replaced this with a AHS s500 heating about 8,000 sq ft. and couldn't be happier!
I'm surprised that you're happier firing the more expensive anthracite. I think that perhaps that boiler's small fire box and smallish fire door for the btu load led to more frequent attention (clinker removal) than would be ideal for you. Regardless, a clinkering type stoker does have the downside of more frequent attention (ash removal) than a stoker or boiler that produces loose ash. I know that you said your were getting some sooting around the house and that's often the result when boilers were installed right up to the stack w/ a straight connecting pipe (very common), however, if a proper flyash settling box were installed behind the boiler, between it and the stack, that would not have been the case.
I like your flex auger feeding the hopper on the new ahs. Do you have auger ash removal with the new stoker?
