Hi, I am new to the forum. I am on heating season three with my AHS S130. I am willing to share my experience with anyone who is interested. The heating system includes a previously installed water baseboard Peerless Oil Boiler with typical zones in the basement of the house and an AHS S130 installed in the garage 50 feet away from the house. They are plumbed in parallel.
The garage has a 35 cubic foot coal bin attached to the side (leanto style) with (2) 4" augers in pseudo-series feeding the #400 pound hopper. A hopper switch controls the feed augers. The S130 has the thermo activated grate option. I got tired of emptying the ash bin so I created an dual auger ash removal system that vacates the ash outside the garage. The thermo grate control also controls the ash augers. So basically it runs by itself and I monitor it.
One load of coal lasts me two years. I ran barley (3/32-3/16) the first two years (they said it could not be done but I managed) and now run pea. I can go on and on about running parameters if you like. I tested air pressure drop across the coal pot from blanked off to nut coal. The delta-P was 2 in H2O to 1/4 in H20 respectively. Pea runs about 3/4 in H20.
The thermo grate set point depends on the outside temperature. When its -20F outside I set the temp around 75F. As it warms up I keep the delta around 70F. I really need a delta-T controller to do this for me. I had some issues with the coal in the feed tube burning so I can talk about that too.
I see you can upload pictures to this forum. I will be happy to show you some pix if interested.
Post pictures of everything. I'm sure all will be interested in your ash removal system. How did you make your coal pot pressure drop measurements. Commercial gauges, manometer, home made U tube? Where did you connect your instruments. If in the firebox, how and what material? Is it a permanent install?

I'll start with the ash auger. I have alot to mention but short on time tonight. Wondering what that big rantangular hole in the base is? The fitting is off the barrel end so you can see the flighting. Yes it's plastic. The ash is cool coming off the grate.
