Cassette 400LNH-INT-PS is a laconic model for modern interiors. It is a recessed fireplace designed to be installed in a niche or a suitable sized portal, it can also be integrated into furniture items. The fireplace can be used without any decorative fuel, or it can be supplemented with a realistic moulage of wood with the effect of smoldering wood. The unique feature of the hearth is that, thanks to its transformer design, it is suitable for use with both Cassette 400 and Cassette 600 firewood. The realistic flame in the fireplace is created with the help of a unique patented Opti-Myst technology: water poured into a special tank is converted into steam, which, in turn, is illuminated by lamps with light filters - brighter at the bottom and dimmer at the top. This creates the illusion of a hot flame with smoke, and the sounds of wood crackling in the fire intensify this picture. The intensity of the flames and the volume of the sounds can be adjusted as you wish. The hearth does not have a heating function, it works in decorative mode only.
