Rocket thermal mass heater with oven. Translated from French: "The oven is based on the model Kiko Denzer, which we have added a fireplace. The rocket does not allow enough heat to cook food, but is perfect for use as a drying oven, dryer or hot plate. For cooking, we make a fire directly on the hearth bricks then push the embers at the bottom when the oven is hot enough. The next day, when everything is turned off, we remove the coal and ashes and put them to finish the rocket burn."
