Abstract
The article focuses on a method of heating buildings by utilizing warm air circulation in closed channels located within external walls, referred to as “collector walls” by the author. These channels are also present in the roof and floors, creating a closed-loop system of interconnected air spaces that form a thermo-circulating heating structure. When the collector walls receive favourable solar exposure from the south, east, or west, the air circulating within the thermo-circulating heating structure is naturally heated through solar radiation, resulting in passive heating. However, in cases where solar radiation is insufficient, an external heat source is re-quired. Heating elements can be directly incorporated into the convection, such as in the lower part of the collector wall.
