GARN is an American alternative energy company and manufacturer of smokeless wood-burning furnaces with integrated hydronic thermal storage.
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.[1][2][3] Lunde was awarded patents in wood-fired hydronic storage in the early 1980s.[4][5]
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.[6]
