Duo-Tec+ Cloud 
Wall-mounted gas condensing boilers ideal for both new builds and replacements
The new Duo-tec+ 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 builds and for replacing an older generator. In addition to the well-known advantages of condensing technology, such as high efficiency, energy savings, and reduced polluting emissions, the new Duo-tec+ condensing boilers are characterized by:
A complete range of models: heating only, with instantaneous DHW production, with integrated micro-accumulation, and with integrated 40-liter accumulation tank. The range also includes the compact version (Compact+), Baxi's first condensing boiler, just 70 cm high and 30 cm deep.
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+ boiler range features a digital control panel with a backlit LCD display. It's easy to use thanks to dedicated, independent buttons for adjusting the domestic hot water and heating temperatures. The display allows you to view all the information and set the operating parameters clearly and quickly.
Wide modulation range 1:7
greater efficiency given by fewer on-off and 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
The innovative automatic combustion control system GAC (Gas Adaptive Control) guarantees a wide modulation range of up to 1:10: high efficiency and energy savings are ensured as the boiler is able to adapt the thermal power produced to the actual power dissipated by the building, avoiding excessive overheating/cooling of the building.
Totally modulating pump
The circulation pump can operate at maximum speed, at minimum speed or in “automatic” mode: in the latter case, the speed (min./max) will be selected so that the flow/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 operates at maximum speed), also in maintenance costs.
