It is time to start installing my Axeman Anderson 130 finally. I purchased four of them at an auction two summers ago for scrap price. To my surprise one of the boilers still had all the banding and plugs in it from factory. So this is the one that I will be installing. I am heating with wood pellets right now and go through 15 tons of them a year. So with this change I am hoping to save at least $1500 a year. I have put up an out building to keep the mess out of the house. I will be piping the coal boiler into the pellet boiler so that I still have use of it for the summer time to heat my hot water.
I do have one question on putting in a chimney and that is how tall do I need to go? I am figuring on going at least bare min of 15 feet. My out building sits caddy corner to the house. The chimney will be erected on the far side of the out building 20-25 feet away from the house and 15 feet behind the house. I am hoping that I don't need to go super high to get above the house roof. Any input is much appreciated.

Jason

They don't need a lot of chimney. Axemans essentially die when the blower isn't running because no air will come through 6-8" of ash without the blower running. :)

Thank you that is good to know.
Also forgot to add, possibly looking to use a digital temp controller for ashing since there was no anthrastat with the unit. Anyone with any experience on this?

Here's some reading at Link >>> How Should an AA130's Fire Look at Full Burn?

??? You want to use the pellet boiler in the summer? That doesn't make any sense to me - either run the AA130 or put in an electric or gas water heater.

Thank you for the reading material McGiever. That is the route that I will be going. As for using the pellet boiler in the summer I only average 15 to 20 pounds of pellets a day to heat hot water via two 40 gallon indirects. One is for me and the other is for my parents. We have a duplex house. I only use about a ton of pellets in the summer.

I go through only about 13 to 13.5 lbs. of coal per day during the non heating months to provide for our homes DHW. Thats less by weight, and also by cost, than for your pellet stoves DHW performance. My AHS S130 and your AA-130 are close cousins.

Larry,
Not apples to apples if he is doing 2 households to your 1. :)

Bet you got him beat on ash output though. :P

I should read more closely. As to the ash of coal vs. wood, that's one fight that coal will never win, not only with regard to DHW, but with regard to any use.

Pellets generally have about 0.8% ash by weight on paper (under strict lab conditions), and perhaps 1.25% by weight in the real world. Coal generally has about 9.5% ash by weight on paper (under strict lab conditions), and about 15% to 17% by weight in the real world.

Best to just buy an anthrastat from Axeman, a beginner doesn't need a science project to add to their adventure. :)

And the anthrastat is so easy once dialed in. Set it and forget it...until it warms up outside...then adjust slightly.

Yup, just don't touch the dial, you can only adjust it with an allen wrench. Touching the dial itself will screw up the calibration. That is how it is calibrated, with the knob. Once everything is set right, you do nothing forever. :)

Heating domestic hot water for two homes is actually better - because there is a better chance of the BTU's produced by the idling boiler going into the domestic hot water rather than the atmosphere. If it were me I would probably try running the AA and see how it does, but to each their own.

Another weird trait of the Axeman design, they don't give up a lot of heat. When I had my handfired, the cellar was warm as toast. WIth the Axeman, it's a bit chilly even standing next to it.

I get plenty of heat from the axeman, keeps my entire basement warm year round. The aa130 actually wastes coal in the summer(incomplete burn) and it would be cheaper to use electric for water heating, I run 24/7/365 though, it prolongs the life of the boiler and dries out the basement every time is rains.
