The Osburn Gusto is a wood-burning cookstove with an integrated oven. It heats a home and cooks from a single appliance. It is recommended for spaces from 500 to 2,100 sq. ft. and has a maximum heat output of 75,000 BTU/h (22 kW).
The oven is stainless steel with a built-in thermometer and a two-position rack system. The oven doors and top are cast iron, which helps hold heat. The cooktop can bring a liter of water to a boil in under 20 minutes. It can be used for everyday cooking, emergency heating and food preparation, or off-grid and backup heat.
The body is heavy-duty steel with a refractory-lined firebox and wooden handles. A large ceramic glass door with an air-wash system gives a view of the fire. Optional decorative accents can change the stove's appearance. The stove uses non-catalytic combustion and is EPA 2020 approved.
