AIRTIGHT
Thanks to a perfectly sealed structure, the stove does not use up the oxygen inside the room. Instead, it draws air from the outside environment and can therefore be fitted in all well-insulated homes and in passive homes as well.
IGNITION IN 3 MINUTES
Product equipped with ceramic spark plug for 40% faster ignition times.
SILENT MODE
Forced ventilation in the stove can be limited at minimum power to ensure maximum silence.
ECODESIGN 2022
The new products were designed in accordance with the strictest provisions of the Ecodesign 2022 regulations on lowering emissions.
NATURAL FLAME
The new Red products are characterised by a wide flame that looks more natural and beautiful to the eye.
USE WITH SMARTPHONE AND TABLET
Thanks to the Easy Connect system, RED stoves can be remotely controlled via a smartphone with a specific application and a Wi-Fi kit included as standard, without additional costs.
