The Classic models are manufactured using heavy gauge carbon steel and have proven their durability over many years of service. All of the Classic models are available as a Dual Fuel Ready Model(standard on the CL 7260 and Pallet Burner). Fuel Burner is sold seperately. All Classic models, except the Pallet Burner, carry a 25 year limited warranty.

The Classic's Ripple Top Firebox design and Heatlock baffle maximize heat transfer area to capture more heat than competitors round firebox designs. Central Boiler outdoor furnaces feature sprayed on urethane insulation to minimize heat loss. Urethane insulation forms an air and water tight seal around the water jacket and won't absorb moisture or leave gaps like fiberglass bats. The large firebox doors allows for the loading of large pieces of wood reducing handling. Each Classic includes a water test kit, and two four foot sections of double wall stainless steel chimney.

Below you will find more information and specs on the Classic models. To learn more about how heat from a Central Boiler gets to your home click here.
