Bay Window Mantis
The Mantis exceeds 90% efficiency– which means it uses about 35 percent less fuel compared to any other vented heater or fireplace system per Btu of heat in your room. This makes Mantis the greenest fireplace you can buy. Because its inexpensive 1 1/2-inch PVC vent pipe can be run inside a conventional 2 X 4 framed wall, the Mantis costs less to install—in materials, time, and labor. The Mantis is the first and only vented fireplace that adds humidity to the dry winter air, making your home feel warmer and more comfortable.
