Chimney collector, from the company Kratki, is designed to be placed at the chimney outlet from the fireplace and is intended to recover part of the thermal energy from the flue gases exiting the combustion chamber of the insert fireplace.

Due to the special arrangement of the pipes, the heat is further transferred to the living spaces. It is a very economical source of heat, as it does not require the use of additional fuel, using only the excess heat in the flue gases flowing towards the chimney.

It is made of steel designed to operate at high temperatures. This material is adapted for use in central heating systems, ensuring high reliability of the device, thermal resistance, and long-term operation.
