The 2200 stove is more suited to more intensive, continuous use. Its 20% larger firebox is designed to maintain steady heat over a longer period. A powerful, ultra-silent 130 CFM fan is available as an option. The glass surface of the bay window is also 20% larger than that of the 1800 model, providing a wonderful view of the fire from every angle. In short, the Osburn 2200 offers a perfect combination of utility and enjoyment!
