DUO-TEC COMPACT E range

New design: change the aesthetics, not the performance.

Luna Duo-tec E and Duo-tec Compact E: the already well-known Baxi boilers present themselves today with a new aesthetic, increasingly modern and attentive to new design trends, which allows them to be inserted into any living context. The control panel has also been completely renewed 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 keep intact the characteristics that have always distinguished the Duo-tec range: Reliability. Robustness, durability and reliability in performance; Efficiency and savings. The reduction of on/off cycles translates into notable benefits in terms of energy saving and lower emissions; Completeness of range. Heating only models, with instant DHW production, and also the compact version with the possibility of outdoor installation. The range has been further enriched with the new models equipped AS STANDARD with the modulating chronothermostat with integrated wi-fi Baxi Ma go (duo tec mago)

The ideal boiler for new buildings and for replacement The Duo-tec E range of gas condensing boilers has been specifically designed in compliance with the requirements of the Ecodesign and Labeling Directives, to make it particularly suitable both for new buildings and for replacing a old generator. The energy class, identified by a letter, expresses a range of efficiency values ​​within which that expressed by the product in question lies. The label was created for the final consumer, so that, through true and comparable data, he can make informed choices by focusing on highly efficient products.

Exchanger preheating function

The boilers of the Duo-tec E range are equipped with the exchanger pre-heating function which guarantees the immediate production of domestic hot water at the set comfort temperature. In fact, the domestic water passing through the plates of the preheated exchanger is already delivered at the desired temperature without waiting times. The function can be easily activated/deactivated by a specific boiler parameter

Boiler info

By pressing the dedicated button, it is possible to view numerous information regarding the operation of the boiler such as: heating system water pressure (electronic pressure transducer present in the hydraulic unit); heating flow/return temperature; external temperature (with external probe installed); domestic hot water temperature.

Efficiency and savings

• greater efficiency given by fewer switching on and off: 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 power dissipated, thus avoiding excessive overheating/cooling of the rooms.

Gas Adaptive Control

It is an innovative system which, 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 self-adapts to the quality of the gas and the length of the flue gas exhaust pipes, maintaining constant efficiency
• the boiler also constantly self-regulates to maintain maximum efficiency values, favoring a reduction in gas consumption and generating less pollution thanks to the continuous control of emissions

Outdoor installation

Duo-tec Compact E boilers can be installed outdoors in partially protected places thanks to the new upper cover kit and lower closure kit (available as accessories). The Duo-tec Compact E range, in fact, is STANDARD equipped with an electronic antifreeze system which guarantees operation down to temperatures of -5 °C: the IPX5D protection also protects the electrical parts from jets of water that may from all directions.
