With an Xzense control (in conjunction with an exodraft chimney fan system), you obtain full control of your fireplace and maximum comfort. No more hassle when lighting and refueling your fireplace. With the click of a button, either on the Xzense itself or on your phone (via the dedicated Xzense app), you get a perfect ”flame picture” in your fireplace. This is regardless of outside temperature, air pressure, wind speed, wind direction and other weather and seasonal factors that influence the chimney draught and thus the workings of the fireplace. Additional benefits are less smoke spillage, better and cleaner combustion, more efficient fuel economy and faster heating. In other words, Xzense makes sense.
