60 Liter Institutional Cookstove
60 Liter Institutional Cookstove

InStove’s clean-burning, ultra high-efficiency biomass cook stoves have been serving children and families in clinics, refugee camps, and schools around the world for years. Our stoves operate on tiny amounts of biomass which can include wood or our sustainable biomass briquettes. Two or three kilograms of such fuel is enough to cook a full pot of food. At the heart of these stoves is an advanced-design combustion chamber, built from 310 stainless steel and surrounded by lightweight insulation. At operating temperature, which can reach 1100 degrees Celsius, the stove literally “burns up the smoke.”
