Compost Water Heater System

Since the microbes in the compost pile generate a lot of energy in the form of heat, we have been able to tap into that energy with the compost water heater system. It has been a great attribute to get through the winter months, and although I haven't mastered the water pump timer and blower, I'm pretty happy with it. The book that we referenced is "The Compost-Powered Water Heater" by Gaelen Brown. I think the concept presents a lot of opportunities for low-cost heat generation for a climate-controlled space. It's on my wish list for my ultimate facility.
