Looking at a AA-220 Coal Boiler

I'm heating right now with an outside wood/coal boiler that is 250 BTUs. I burn about 7 tons of bituminous coal. My house is 2,000 sq ft and the garage is 3,000 sq ft and it is in floor heat. I've been looking at the 220 coal boiler and was wondering if anyone has an idea if it would heat 5,000 sq ft? And about how much coal I would go through? I live off of Lake Erie where it gets really cold.

If you do not have a shed to put it in your going to need one.
Is your current system an open system under pressure in a closed system.

You may want to ask Matt about purchasing one of the outdoor stoker boiler systems they have been trying to bring on the market. Send Matt a PM via the forum or call him at the shop at Leisure Line to see if his stoker boilers can burn Bituminous Coal first. Calling him will get you an answer to your questions faster.

From what I remember the Electric Furnace Man DF520 underfed stoker burns Bituminous Coal and is half as costly as the outdoor Portage and Main coal stoker(17000+) and would need to be in an enclosed building of some sort and not in a garage unless the boiler was walled off with a fire proof door and a bunch of other work due to the national plumbing and fire codes and your insurance companies actual requirements.

You may want to simply fill your current boilers fire box half full of firebrick(half the firebox cubic foot volume) yes half the volume to the flue breech if its a rear or top flue breech to add thermal mass and cut your wood and coal consumption. I did exactly that 6 years before I switched to a dual fuel coal stoker as I finally decided to invest in a coal stoker after breaking my nose due to slipping and falling on ice while making firewood with my firewood processor four years ago.

A pallet or two of full fire brick and a piece of channel Iron as wide as your inner fire box width and half as long as the fire box may be all you need as the fire brick will make the fire burn hotter with smaller fires and the firebrick will also shed heat back into the firebox. It worked for me and I wish I had done it 35 years ago. It lets you make a smaller hotter fire without wasting a lot of fuel in unburned smoke out the chimney stack.

My thoughts anyway.
