Main disadvantage of the rocket heater is the indispensability of frequent watch over. Gamera stoves is designed to last at least ten seasons under normal operation and storage. It is designed for optimal heat exchange, durability and weight. The body is made of black steel 1.5mm to 4mm thick. It can withstand 1200C for short periods. Its maximum working temperature is up to 1100C. The core is made from expanded vermiculate 25mm thick. They are very convenient more caloric than wood given the same volume, have longer refuel period and are cheaper than pellets. Pellet are not suitable fuel! In such cases the cost for heating can be reduced ten times!Įco-briquettes are exelent fuel also. Much cheaper alternatives can be found as offcuts from wood processing industry, branches that are left away or offcut from construction timber. Since Gamera stoves uses relatively thin wood it is not necessary to buy regular firewood. Hitting in the heated walls of the heat riser smoke and wood gas burns and gas remains 99% water vapor and CO2, which wrap the metal casing inside out through the chimney.īecause of its high efficiency the heater consumes 2 to 3 times less fuel and does not produce soot on the flue pipes. The animation better depict what happens in the combustion chamber. The exhaust gases leave the stove from outlet withc is at the bottom of the stove with mid temperature around 140C. This leads to excellent heat release on one hand and creates own draft on the other. Because the hot gasses run all around the body they cool down. Afterword flows through the gap between the burning chamber body and the metal corpus of the stove. All smoke and gases released from the fuel during the primary combustion self-combust here, generating twice more heat and decomposing to 99% CO2 and water steam.Īfter leaving the heat riser the exhaust gases (99% H2O and CO2) hit the top metal plate of the stove’s body. The secondary burn takes place iside the heat riser which heats up to 1000C. It is made of hi-heat resistant material that is additionally insulated. The low horizontal tunnel leads the products from the primary combustion (heat, wood gas and smoke) to the vertical part of the burning chamber ( heat riser) which acts as an inner chimney. The air intake is in the center of the fire pit and the draft leads the air down, around the fuel and inject the flames in the horizontal tunnel on the lower back side of the primary combustion chamber. The fuel is loaded vertically inside the primary combustion chamber where the same processes take place as in regular stove but upside down. All Gamera models stoves are based on the principles of the so-called rocket heaters that features “L” – shaped burning chamber.
