A balanced flue is a glass fronted gas appliance, which is completely sealed from the room into which they are installed and vents directly to an outside wall. Air is drawn in from the outside for combustion purposes increasing its efficiency through an outer pipe whilst the inner pipe vents the combustion gases safely away to the outside of the property.
There is no electric supply required; hence no sound or natural air circulation is experienced as with a power flue appliance. There is also a choice of either outset or inset versions available.
