Abstract: A cabin has a heating system integrated into one of its side walls. The heating system is arranged between an inner wall layer and an outer wall layer and has an ambient air channel with an inlet at the bottom and an outlet at the top. The heating system is designed to be space-savingly arranged within the cabin and to ensure a uniform heat distribution inside the cabin. The cabin thus has a large-surface radiant heating system built into the side walls and supplemented at its rear side relative to the outer wall layer by a reflecting layer that reflects the radiation of the radiant heating system into the cabin through the wooden inner layer.
