Here is a superefficient wood fired heater you can build for yourself in a weekend for less than a hundred dollars. This book explains in detail exactly how to build one, then how to use it in a range of applications. We discuss where to find them, what to pay and how to make use of found and recycled parts. The section on fire and fuels is thorough but simple; we tried to keep away from numbers wherever possible. There are success stories, case studies, references and where to find further information, all heavily illustrated. Home heating can be expensive both in capital equipment and in running costs. If we heat by gas, oil or electricity we are supporting a big corporation and impoverishing ourselves. By building an extra efficient heating system you will be one more big step off the treadmill and your move to self-sufficiency and true wealth. Good luck with your stove!
