One idea, simplify the installation in an already existing chimney. This new brand insert has been designed with this in mind. To simplify its installation, this insert is mounted on a pivot to facilitate its connection, but also its maintenance. Its combustion chamber and its size will allow it to adapt perfectly to your fireplace. Its aesthetic hinged door and its Autopilot automatic regulation will certainly seduce you.
Hwam's Autopilot system mechanically regulates combustion, thanks to a bimetal spring, which under the effect of heat, will expand, or on the contrary shrink when the fire weakens, thus closing more or less air inlets.
