Product detailed description

Output: 9,3 – 25 kW, combi with DHW, forced flue gas discharge (turbo) - Baxi  Luna3 Comfort AIR 250 Fi

The boiler includes a panel that, via a special receiving unit (interface) built into the front of the boiler, allows wireless control and programming of the heating and DHW modes. Once an outdoor temperature sensor is connected, it acts as a programmer for the built-in weather compensation control. This control panel is included in the price of the boiler.
