We were amazed at how much wood can fit in the Froling FHG wood gasification boiler. Scott Nichols shows us how much wood will squeeze into the boiler. The boiler has a large door opening and 5 cu. ft. fir box (7.4 cu. ft. on the larger Froling FHG). For more information, please visit us at: www.woodboilers.com or call us at 1-800-782-9927.
