Luna Duo-Tec+
Wall mounted gas condensing boilers ideal for both new build and replacement
The new Duo-tec+ range of gas-fired 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 an old generator. In fact, in addition to the already known advantages of condensing technology such as high efficiency, energy saving and reduced polluting emissions, the new Duo-tec+ condensing boilers are characterized by:
-
Complete range of models : heating only, with instantaneous DHW production, with integrated micro-storage tank, with integrated 40-litre storage tank. The range also includes the compact version (Compact+), the first Baxi condensing boiler in just 70 cm in height and 30 cm in depth.
-
Digital control panel with backlit LCD display
-
Wide modulation range 1:7 the reduction of on/off cycles translates into significant benefits in terms of energy savings and lower emissions
Digital control panel
The Duo-tec+ range of boilers is equipped with a digital control panel with backlit LCD display, easy to use thanks to dedicated and independent keys to adjust the temperature of the domestic hot water and the heating. The display allows you to view all the information and set the operating parameters in a clear and immediate way.
Wide modulation range 1:7
- greater efficiency given by fewer starts and stops: with a high modulation ratio, the reduction of the continuous on/off cycles leads to a significant reduction in consumption (by 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 premises
Gas Adaptive Control
The innovative GAC ( Gas Adaptive Control ) automatic combustion control system guarantees a wide modulation range up to 1:10: high efficiency and energy savings are ensured as the boiler is able to adjust the thermal power produced to the actual power dissipated from the building avoiding excessive heating/cooling of the building.
Total modulation pump
The circulation pump can operate at maximum speed, minimum speed or in "automatic" mode: in the latter case, the speed (min./max) will be selected so that the delivery/return ∆T in heating remains constant at 20 °C thus ensuring a significant reduction in pump consumption and, given the lower mechanical stresses (compared to a pump that always runs at maximum speed), also in maintenance costs
Characteristics:
- Wide modulation range up to 1:7 greater efficiency and silence
- GAC (gas adaptive control): automatic combustion control
- High efficiency circulation pump with total modulation
- Digital control panel with large backlit LCD display
- Arrangement for combination with the Baxi integrated solar system
- Ø50 mm exhaust pipe: solution for restoring flues - mod. 24 kW
