I am currently heating a 3500 sq/ft shop and 2100 sq/ft house w/ a pellet furnace and a pellet stove. I am looking to heat an additional 1500 sq/ft of the shop and 1500 sq/ft of the house. Needless to say maintaining what I have now is the limit of the work I want to do. I would like to do an outdoor unit to keep the dirt outside. I am located in central PA so coal is readily availible. The shop and house are very well insulated. On the coldest of days I use 4 bags (160lbs total) of pellets for both locations. What would you buy and why? I can't seem to find an outside unit that lives up to all the "hype" the manufacturers claim. I know one thing... I only want to maintain one unit that is coal fired.

One other big concern is ash maintenance. I know some of the outside units require attention daily for dealing with ash. I would prefer to only deal with ash once a week max if possible.
