The Harman XXV-TC is the pellet stove for people who love the look of cast iron. Its oak leaf styling gives it real old-school character, and the 181-1/8 square inch window of flame-reactive mirrored glass gives you a big view of the fire. Pick Matte Black, Porcelain Twilight, or Porcelain Majolica Brown to suit the room.
Behind the classic face are modern controls. EASY Touch Control and a wireless room sensor handle the temperature, Harman's Exhaust Sensing Probe fine-tunes the burn, and Whisper mode keeps things quiet. The 65 lb hopper has a tinted lid so you can see the fuel level. It's certified to the EPA 2020 standard at 1.75 g/hr.
