wood-burningsteelnatural convection

Overview
The innovative Lean model is developed for houses and apartments with limited space and low heat demand. This insert features a deliberately reduced installation depth. The Lean 3RL-70h in U-shape, equipped with three glass panels, provides a wide panorama of the fire despite its compact format. It uses multi-part combustion-chamber glazing with an infrared coating to reduce radiation distance, increase combustion-chamber temperatures and minimise soiling. With a 150 mm flue outlet, the insert is also compatible with small-diameter chimneys. The compact format ensures particularly efficient and durable wood fuel use.
