Closing down the system

Due to changes in house ownership, I will be soon dismantling the composting toilet system. I have done a bit more tweaking, which hopefully I can document before I close the system down. Perhaps once I have more time, I can post additional photos. For example, I put a heat exchanger in the exhaust plenum that captures some of the waste heat and transfers it to an open loop propylene glycol recirculating system which keeps my shallow water line and horse stock tank from freezing, even on the coldest Wisconsin winter days. This significantly reduced my electric costs associated with heating the stock tank using resistive stock tank heaters.
