Outdoor Wood-fired Hydronic Heater

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). Talk to your local dealer for more information.

"Before, with our two indoor wood stoves, we had problems with smoke in the house, soot, and dirt. We were concerned about how safe they were, and we had to load them every three hours. With our Central Boiler Classic outdoor wood furnace, we feel much safer, and we only have to load it about every two days. Also, my son has asthma, and since we got the outdoor furnace, he's had fewer problems. I think it's because the air is much cleaner inside now. That was a real unexpected benefit. Probably the best one of all."
