The Eco3 Rocket Stove is the largest in our range, standing at 33″ (825mm) height from the floor (when standing on its feet). The wood feeder system is the same as in Eco1 and Eco2 and the footprint is also the same at 18″ (450mm) wide x 28″ (700mm) long on the base. Add another 6″ (150mm) at the back for the exhaust hood for the total space required.
