We revisit Ernie nearly 16 years after the first video we made! His GARN is still operating after 25 years of burning!

This video showcases the real-life operation of a GARN with its owner Ernie.  The GARN was installed in 1991 and it heats a 5100 sq ft house and a small outbuilding in Northern Minnesota – one of the coldest parts of the country. The movie speaks for itself about the clean and easy operation of the GARN WHS.
