Heatmaster G-Series

    Heatmaster SS G-Series outdoor wood boilers are the latest in outdoor wood boiler technolodgy. They use a system known as wood gasification in which the wood in the fire box is heated to temperatures in excess of 700°F, causing the wood to change into a gas in the form of carbon monoxide, hydrogen and carbon dioxide. This wood gas is sucked into a secondary burn chamber, made of refractory, located below the fire-box, and burnt, creating temperatures higher than 2000°F. The exhaust is then drawn upward through 8 verticle heat exchange tubes, transferring the heat into the water in the surrounding water jacket. Each of these heat exchange tubes contain a spiral shaped component called a turbulator, which causes the exhaust to follow a spiral path up the tube, creating greater efficiency. It is then drawn through a draft inducer fan located in the back of the unit below the chimney and forced upward and out, with an average exhaust temperature of less than 250°F. This design allows the Heatmaster SS G-Series to be the most efficient, cleanest-burning and easiest-to-use gasification outdoor wood boiler on the market today. On an average, a gasification outdoor wood boiler will burn around 50% less wood than a traditional unit.
