I'm just looking for some insight as to where my boiler, a Leisure Line AA-220, comes from? I know the AA is Axeman Anderson and 220 is the rated output or so they claim. In doing Google research all I can seem to find related to AA is the Anthratube? I keep reading how brilliant Axeman and Anderson were at building efficient heat exchangers but I can't find anything on how mine is designed. Just looking for a little history of my boiler and how it came to be. Was my pressure vessel a pre Anthratube design that LL used and is the Pocano stoker LL design also? I'm starting to get a fascination for this stuff but don't know much about the history so I have been trying to educate myself. I'll do a little research on EFM pressure vessel design also, don't have a clue how they are transferring heat?

Quick version...When it comes to heating larger homes or commercial buildings and greenhouses our newly designed Leisure Line AA-220 boiler is your best bet. The AA-220 is a two piece
design with a Leisure Line base unit featuring our reliable Double-Pocono coal stoker feeder. The pressure vessel unit sits on top and is manufactured by Axeman-Anderson
with over 60 years experience in the industry. This boiler configuration was introduced in 2011 and has proven to be reliable and efficient.
This AA-220 hydronic, UL Tested boiler is capable of heating the typical single family home up to 5,000 sq. ft. The AA-220 unit is also certified to be used in commercial
building structures with a concrete or stone floor. This quality American made 375k btuh rated pressure vessel is a double pass, vertical firetube design with 49 sq ft of
heating surface, 42 gallon water capacity, and is ASME certified. With it’s massive heating surface and double pass design this unit yields up to 90% efficiency while providing responsive operation. Even though low in price this boiler is not short on features, it comes standard with the following components: Honeywell 7124 Electronic Triple Aquastat, Honeywell 6006A High Limit; a idle fire circuit to keep the fire lit; a 5 GPM Domestic Hot Water Coil; large ash pan and 320# hopper; 220K btuh input coal double stoker unit.

Yea I read the flyer on their site also.... not the answer I am looking for. Is this a early design? Is the Anthratube their best design and what they went with for their production that still sells today?

Sorry SM, about the only thing the LL-AA220 has in common with an Axeman Anderson is the fact that they burn anthracite coal.
The Axeman Anderson was designed and went into production in the 1940's. It is still in production today and is regarded by some to be the most efficient coal boiler design ever. There have been no major changes to the design since the beginning.
The Eshland and AHS Coal Gun are the same basic design. I have never heard of any other boiler that is anything like it.

I guess my confusion lies in the orientation... it seems similar to mine but the tubes are horizontal, which in my boiler they are vertical.StokerDon wrote: ↑Mon.

Sounds like your boiler is a fire tube boiler that is built in the Axeman Anderson plant. The Axemans don't have tubes at all. -Don

I have lived near coal country all my life. Until about 3 weeks ago, I had never seen an Axeman Anderson in person. The main reason I wanted one was because I couldn't figure out how they worked!
Now I know, kind of.

I believe that the LL-AA220 (as well as the 110) starts out life as an AA boiler intended for oil, NG, or Propane, and LL modifies it to add a coal stoker to it. Ditto for the LL forced air furnaces.

That's a better question for Larry. He has been running his Coal Gun for quite a few years now and has cleaned it a few times. My 130M has only been running for a week and a half now. The separator does spit the fly ash out on top of the other ash so it looks like it works.

Yup there’s nothing alike, It’s very cool to see one in person, it’s hard to understand the operation without.

I have burned 2 ton so far and noticed my draft has went down. Inspected the breech of the boiler and there wasn't very much under the 3' vertical flue. I went outside and inspected the PV and it was about plugged. Pulled the PV motor/fan assy out and there wasn't a whole lot there. Just didn't think I would get that much fly ash with a 12' flue run? Seemed to just stick to fan blades and exhaust deflectors. How often so those of you with a chimney have to clean it out?StokerDon wrote: ↑Mon.
