Thermorossi wood heating insert Skyline 540 - 8

Highly efficient wood-burning firebox with full-screen technology, allowing for an unobstructed view of the flames. The extremely slim profiles of the screen-printed glass guarantee the largest viewing area in its category (H x L - 27.5 x 53.5 cm).

Thanks to its low height, it's ideal for utilizing existing open fireplaces or creating new ones. The spacious and robust, impact-resistant combustion chamber is made entirely of cast iron and allows for burning logs up to 50 cm long. Features include a removable ash drawer, a stainless steel and cast iron heat exchanger, and Smoke Bypass technology: when the fire door is opened, the Smoke Bypass is automatically activated to prevent smoke from entering the room. The device, which rotates 90°, throws unburned residue that accumulates in the flue into the ash drawer. This ensures the heat exchanger remains efficient at all times, with a consistent efficiency of over 85%. Smoke Bypass also allows for simplified, thorough cleaning at the end of the season without disassembling the combustion chamber, and facilitates easy chimney inspection.

Natural convection operation is therefore possible: by inserting the ventilation kit with two thermostat-controlled axial motors – Airbox4 (optional) – the wood-burning insert is ventilated and the air can be directed into adjacent rooms. A switch activates the two-stage ventilation. Features include concealed primary, secondary, and tertiary air regulation, a self-cleaning glass system, a reversible firebox door with screen-printed glass (left/right), a flush handle, concealed hinges and screws, and the option of external combustion air intake (ø 60 mm) and a flue gas outlet (ø 130 mm).
