Fireplace heating principle

The principle of fireplace heating is to use the heat generated by burning wood or other fuels to transfer the heat to the surrounding air, thus increasing the indoor temperature. Fireplaces usually consist of combustion chambers, flues and chimneys. When wood or other fuels are burned, the heat generated will be absorbed by the metal wall in the combustion chamber and then transferred to the chimney through the flue. The height and shape of the chimney help to exhaust the smoke outside and transfer the heat to the indoor air. When the indoor air comes into contact with hot flue and chimney, it will be heated and rise, thus forming a convection cycle and raising the temperature of the whole room.
