The S130 boiler is becoming quite efficient, even during these balmy January days. It seems that I'm currently using closer to about 1.5 lbs. of coal per degree day. For the past three days I'm only using on average about 35 lbs. per day. I went three full days without adding, and yesterday evening I added 106 lbs. to completely top off the hopper.

She' working great right now. I wonder if my earlier inefficiency and residual unburned/partially burned coal in the ashes issues were all related to initially firing it up without any pre-load of ashes?

LET IT BURN for a significant time period,, in my case over an hour, but my boiler is the AA260... with a 130, maybe only an hour..

AHS spells it out very well in their latest instructions,, they say to put a large a BTU load on the system as you can,, a cold house, cold water, and use domestic hot water,, keep the fire burning untill there is no doubt that the fire is all the way across the firebox and all the way to the grate, or the layer of old ashes.. make the fire at least 1/2 the depth of the firebox...

THEN once the fire is well established, put the belt on the auger,(or flip the ashing switch on for a AHS), let it feed the fresh coal, and let the ashing handle free to operate.. you will NOT see any ashes in the ash pan for a day or two. This is normal,,

It depends on when the unit was built. Mine is a 2006 model and has the round coal hopper. I holds 300 lbs.
