System Overview

The RAIS Bionic Fire is a modern, stylish fireplace with record-breaking heating efficiency.

The Bionic Fire's dual combustion chamber design is based off a new system, which is used in highly efficient industrial fireboxes.

Its fully automatic air regulation makes for simple and effortless operation: once the fire reaches a sufficient temperature, the stove redirects the fire into the secondary chamber, giving the Bionic Fire its impressive double flame.

The RAIS Bionic Fire uses innovative industrial technology to create an elegant & environmentally-friendly residential heating solution.
