Spartherm Stove - Linear Front 73x37 RLU

Rectangular wood fire for passive houses.

Energy-efficient built-in fire with flexible choices of installation

The Linear Front 73x37 RLU is a trendy hole-in-the-wall wood fire that can be installed in an existing chimney or, thanks to its narrow depth, in many other domestic settings.  It has closed combustion, which makes it ideal for modern, well-insulated homes and you can choose from black or white chamotte linings.  The useful elevating door with a fixed handle completes the story.
