The Central Boiler Classic Edge is an outdoor wood gasification furnace available in three models with a water capacity ranging from 150 gallons to 330 gallons. The unit has a vertical heat exchanger, which provides optimal heat transfer and allows exhaust particles to drop to the bottom, reducing the need for maintenance. It also has an air charge tube, unique to Central Boiler, which improves efficiency and lowers emissions by controlling airflow while preventing coals from falling into the lower chamber. Air-tight, waterproof urethane spray foam insulation and an insulated chimney help lock in heat and reduce wood usage, and the FireStar II electronic controller automatically adjusts the primary and secondary air to optimize the gasification process.
The 2016 starting price of the Central Boiler Classic Edge is $6,490.
