Device for purifying exhaust gases from a fireplace

A system for heating a room comprising:

• a fireplace;
• and
• a device, comprising:
• a housing which accommodates functional components of the device;
• an inlet portion which is provided to receive exhaust gases from the fireplace;
• an outlet portion which is provided to discharge exhaust gases from the device, wherein a controllable draught regulator is assigned to the outlet portion;
• a control unit configured to:
• receive, via one or more sensor units in communication with the control unit, data regarding the exhaust gases;
• and
• adjust, based on the data, the controllable draught regulator to prevent a negative influence of a chimney draught on pressure conditions within the device or on pressure conditions within the fireplace;
• a bypass portion which is configured to establish a direct connection between the inlet portion and the outlet portion and which can be closed by means of a first mechanical flap arrangement;
• and
• a cleaning portion which extends between the inlet portion and the outlet portion for guiding an exhaust gas flow and which is provided with functional components, wherein the functional components comprise:
• an electrostatic filter unit for separating fine dust particles;
• a centrifugal separator unit for removing particles from the exhaust gas;
• and
• a fan unit for driving a flow of the exhaust gas through the cleaning portion,
• wherein the device is coupled to the fireplace through its inlet portion and a chimney coupled to the outlet portion.
