As the leader in the industry, Central Boiler has developed the E-Classic 2300 and the E-Classic 1400, the outdoor wood gasification furnaces that shatter virtually every preconceived notion about emissions and efficiencies of wood heating. The E-Classic uses a three-stage combustion process to burn wood so completely that combustion efficiencies approach 100%. With the patent-pending, self-cleaning heat exchanger, the E-Classic produces extremely low emissions per Btu of heat delivered and is one of the cleanest ways to heat with wood. It can heat multiple buildings, domestic water, shops and more, and can replace multiple indoor wood stoves. Burning wood (a totally renewable resource) results in no net increase in carbon dioxide, a major greenhouse gas emission.
VT, ME, NH, MD and MA regulate outdoor hydronic heaters and the E-Classic 2300 and E-Classic 1400 meet the regulations in these states.
