Wood boilers provide a convenient, safe, and environmentally responsible way to heat your home and hot water. Wood boiler owners are ensured of high heating efficiency, low heating costs, and use of an abundant, locally available, renewable fuel. The wood gasification combustion technology used in BioHeatUSA wood boilers is the most efficient way to burn firewood. As a result, our boilers use substantially less wood than conventional wood boilers and outdoor water stoves. Additionally, this high efficiency burn technology produces little or no creosote, virtually eliminating the risk of a chimney fire and greatly reducing greenhouse gas emissions.
