It is disclosed a high-efficiency chimney and stove deterring tar creation into the combustion chamber via a double wall wherethrough air is circulating, heated up by convection and radiation and conducted to the combustion chamber through a plurality of peripheral openings existing therein at different heights. The clean hot air ingressing the combustion chamber through said openings causes the tertiary combustion of the unburned materials produced in the primary combustion phase; this leads to enhanced combustion efficiency, reduced exhausts and avoidance of tar creation on the combustion chamber’s walls. |
