History
GARN pioneered wood gasification in conjunction with thermal storage in 1984, after GARN founder Martin Lunde developed the technology under a contract with the U.S. Department of Energy in the late 1970s, along with researchers Richard Snyder and James Buesing. Lunde was awarded patents in wood-fired hydronic storage in the early 1980s. In April 2015, the GARN WHS-2000 was the first ever hydronic wood heater to pass the EPA's Phase II "white tag" certification using cord wood as fuel.References
