Gaelan Brown, the founder of CompostPower.org has written a book about what is described as “a revolutionary approach for space heating and generating hot water.” Brown has worked with engineers and compost scientists for years to refine methods of composting that can heat greenhouses, barns, buildings and hot water, all without combustion.
The Compost-Powered Water Heater provides detailed plans for constructing small do-it-yourself systems with wood chips and sawdust, step-by-step illustrations and photos to guide readers through the process and calculations to help estimate the heating capabilities of various approaches. The book includes an overview of a large engineered system that can be scaled to suit any heating need, according to the publisher, The Countryman Press, Woodstock, Vermont.
According to the CompostPower.org, the book aims to be a valuable tool for anyone interested in compost heat recovery. It includes several case-study style reports including images and diagrams on projects from Norway, Chile, Siberia, Canada and the United States.
Several university campus projects are detailed, including the world's first compost-heated college dormitory at Evergreen State College in Washington State, the engineered Isobar system at the University of New Hampshire and a multiyear research project for greenhouse heating at the University of Vermont. The Compost-Powered Water Heater is available for purchase on Amazon.com.
Brown has taught workshops on the topic at Vermont’s Yestermorrow Design Build School and the University of Vermont. Brown also is on the senior management team of Agrilab Technologies, Enosburg Falls, Vermont.
