Book 63 pages in PDF form

This book was first published in 1994, but has been revised, updated and expanded several times since then. It was intended for professional hearth specialists such as system installers, retailers and chimney sweeps who need to design systems that function well and to diagnose problems they encounter in their work. It was made part of the course of study for professionals by the Wood Heat Education and Research Foundation (WHERF) which was the educational arm of the Wood Heat Alliance. The Masonry Heater Association (WHA) also made the book part of its certification course for heater masons. Because it is a very large file with many illustrations, it has been divided into three separate PDF files, as follows:
