The Inside Story On Outdoor Wood Furnaces.
The Central Boiler Classic^® models 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. The Classic models are available in a choice of 9 different colors with the exception of the CL 7260 and the Pallet Burner which are available in charcoal.

All of our models are available with a Dual Fuel Ready option (standard on the Pallet Burner). Contact us for more information.

"It is efficient, easy to load and clean out. Has the best warranty coverage of all outdoor furnaces that we checked. We're very happy with the furnace, have no complaints, and love the design. We heat our water as well as the house, and the house has nice, steady, even heat."
