General Features

BAXI LUNA DUOTEC E




The Duo-tec E range of condensing gas boilers has been specifically designed to meet the requirements of the Ecodesign and Labelling Directives, making it particularly suitable for both new construction and for replacing an older generator. The energy class, identified by a letter, expresses a range of efficiency values ​​within which the product in question falls. The label is intended for the end consumer, so that, through accurate and comparable data, they can make informed choices and choose high-efficiency products.


Main features

• New modern and elegant design for the entire range;

• Wide modulation range up to 1:7 (1:6 mod. 1.12) greater efficiency and silence;

• GAC (gas adaptive control): automatic combustion control;

• Digital control panel with large backlit LCD display;

• Baxi Mago AS STANDARD: Dedicated app for smartphones and tablets for remote boiler control (for Luna Duo-tec E 24/33 Mago models); accessory available on request for all other models;

• Various integrated systems;

• Also external installation;

• Predisposition for combination with the integrated Baxi solar system;

• Connection to a Ø50 mm rigid and flexible exhaust pipe: solution for chimney renovation - for the 24 kW model, total length 40 metres (intake + exhaust);

• Totally modulating pump with de-aeration.



New design: changes the aesthetics, not the performance.



Luna Duo-tec E and Duo-tec Compact E: the already well-known Baxi boilers are now presented with a new aesthetic, increasingly modern and attentive to the new design trends, which allows them to be inserted into any living environment.

The control panel has also been completely renovated and is equipped with a new backlit LCD display that is even clearer and easier to use thanks to dedicated and independent keys.

The new boilers, even more beautiful and modern thanks to the restyling, still maintain intact the characteristics that have always distinguished the Duo-tec range:


Reliability: robustness, durability and reliable performance;
Efficiency and savings: the reduction in on/off cycles translates into significant benefits in terms of energy savings and lower emissions;
Complete range: heating-only models, with instantaneous DHW production, and a compact version for outdoor installation. The range has been further expanded with new models equipped with the Baxi Mago modulating chronothermostat with integrated Wi-Fi as standard.

Wide modulation range 1:7

Greater efficiency due to fewer on-off cycles: with a high modulation ratio, the reduction of continuous on/off cycles leads to a significant reduction in consumption (8-10%) and an equal reduction in polluting emissions.

Adjustment of the thermal power produced to the dissipated power, thus avoiding excessive overheating/cooling of the rooms.



Gas Adaptive Control


It is an innovative system that, thanks to new control electronics and a new electronic gas valve, guarantees automatic combustion control to constantly maintain maximum efficiency values.

Advantages:

• there are no manual interventions - reduced measurements, calibrations or nozzle changes;
• with this system, the boiler automatically adapts to the quality of the gas and the length of the flue pipes, maintaining constant efficiency;
• the boiler also constantly self-regulates to maintain maximum efficiency values, promoting a reduction in gas consumption and generating less pollution thanks to continuous emission control.
