This is the Avalon “Arbor” cast-iron pellet stove. For its size, this stove will really compete with the big boys. It produces 45,000 btu of heat for up to 2,250 square feet. The Arbor holds one bag of pellets, has automatic operation and a ball-bearing ash drawer. Avalon has really added the detail in this stove with grape vines on the sides and “Arbor” stamped on the hopper lid.
