Classic Edge Models

  1. Designed to Perform – With innovative features like a patented air charge tube that adds air in all the right places while keeping the coal bed from falling through, to the patent-pending vertical heat exchanger that optimizes heat transfer, the Classic Edge is the perfect combination of performance and value.
  2. Easy to Operate – With Central Boiler’s FireStar II electronic controller optimizing the gasification process, the Classic Edge is one of the easiest ways to heat with wood.
  3. Higher Efficiency – Fire burns down through the Fusion Combustor where extremely high temperatures aid in complete combustion, resulting in high efficiency and extremely low emissions.
  4. Less Maintenance – Vertical heat exchanger optimizes heat transfer and requires little maintenance. Heat exchanger includes integrated cleaning system and, if needed, a removable access plate, a Classic Edge exclusive.
  5. Burns Less Wood – A hallmark of Central Boiler furnaces for over 30 years, spray-on urethane foam is the ultimate airtight, waterproof insulation that locks the heat in to reduce wood usage, even at the coldest temperatures.
  6. Certified – The Classic Edge 350, 550 and 750 are U.S. EPA Certified.
