Hudson River Stove Works is pleased to introduce its cast-iron pellet insert. With a Btu rating of 42,500, it heats up to 2,200 square feet. The Chatham enamel-coated insert stove and the overall line of 10 individual models all use the same control board, auger motor, combustion fan, convection fan, pressure sensor, and snap disks. The large selection of models, paired with simplicity of service, amounts to a unique combination.
