The Inside Story On Outdoor Wood Furnaces.

The Central Boiler Classics™ are engineered to be the most efficient outdoor wood furnaces available while providing the best durability, low maintenance features, and an appealing fit and finish. Models are available in a choice of heavy gauge carbon steel (CL and PB Models) or titanium enhanced stainless steel (SCL Models). Carbon steel models have proven their durability over many years of service. The SCL models offer a stainless steel choice with the entire firebox/water jacket assemblies constructed of titanium enhanced stainless steel that meets the stringent ASTM requirements for the correct alloy composition on all heat lots.

Many of our models are also available with a Dual Fuel Option
