I'm new here, but I'm working on something that might be of interest to the nerds. I've built a bio-meiler, which is a compost pile with water pipe running through it, with the intention of circulating it through the bedding of my brooder. I'm not up and running yet since the pile is only around 80 degrees, but as soon as I can reliably "harvest" the heat in the pile I will.

I used 100' of PEX pipe, which, in hindsight, is about half as much as I need for this system. That, and I picked up a 100' roll of 4' tall fence to enclose the compost.

The pile will be roughly 6' in dia and 4' tall.

Here it is half way full of wood chips and manure. The manure was not as good as I'd hoped, and the pile didn't start heating until I put a truck bed load of hot leaf/manure compost into it.

This temp was taken today with an outside temp of around 25f. A few more days, and it should be hot enough to run water through. I don't want water to freeze in the system.

The PEX inside is just coiled under the center of the brooder in probably a 4' circle, and stapled into the sod. I have 5" of wood chips on top of the coils. My brooder is a 10' square. I'm hoping to reduce the need for heat lamps for brooding future flocks. I'm confident that a system like this can circulate 120 degree water for several months, and I intend to create a system like this to heat part of a tunnel for over-wintering my flock. I'll update with pics of the pump and reservoir asap.
 
This is a stellar concept! I toyed around with the idea of heating a brooder with decomposing grass cuttings, but quickly figured out I would need a much larger mass than was practical. (My engineering knowledge is strictly intuitive.)

I think folks would be interested in what region you live in that this experiment is taking place. I suggest you update your profile.

Updated! I'm in Ohio, where it's currently in the single digits. The heated area is only the size of my "Ohio Brooder" which is only 4' square. I got a tree trimming company to dump several loads of wood chips, which is what most people use for a biomeiler. If you have a large enough pile of them you don't need much nitrogen as the pile will naturally have a decent C/N ratio. Not ideal, but good enough to heat up. I have another very big pile that probably has 150 bags of leaves from around my neighborhood that I've added 2 truck bed loads of horse manure to, and a hundred or so pounds of coffee grounds. That pile is 140-160 degrees currently, even in these temps. If I was smart I would have just filled the thing with that hot stuff, but I didn't.
 
Ha! You're slightly behind your own learning curve! Just foolin' with ya!

This is a fascinating endeavor. It's nearly inconceivable that decomposing mass can get that hot, especially when it's so darned cold.

Please keep this thread updated as you progress with your project. It has the potential of generating a good deal of interest, especially if you include details (pics) on how you are assembling the brooder.
