Cloud Duo-Tec+

Digital control panel

Baxi

The Duo-tec E range of boilers is equipped with a new digital control panel with an even more backlit LCD display, clearer and simpler to use thanks to dedicated and independent keys for regulating the temperature of the domestic hot water and of the heating. The display allows you to view all the information and set the operating parameters in an intuitive and immediate way.


Efficiency and savings

Wide modulation range:

  • 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
  • adaptation of the thermal power produced to the power dissipated thus avoiding excessive overheating / cooling of the premises

GAC Gas Adaptive Control

Baxi

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

Advantages:

  • there are no manual interventions – reduced measurements, calibrations
  • with this system, the boiler self-adapts to the quality of the gas (methane) and to the length of the flue gas pipes, keeping the efficiency constant
  • the boiler also constantly regulates itself to maintain the maximum efficiency values, favoring a reduction in gas consumption and generating less pollution thanks to the continuous control of emissions.

Fully modulating pump with de-aeration

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.

During the first ignition phase, we recommend activating the automatic de-aeration function. This function eliminates the presence of air in the heating circuit and therefore avoids any blockages of the boiler, overheating of the system, etc.


Guidelines in case of replacement of a conventional boiler with a new condensing one

There are two main problems that can be encountered:

  • Flues and smoke exhaust duct
  • Condensate drain

To overcome the above, Baxi recommends:

the use of a Ø50 mm exhaust pipe

Baxi

Baxi has in fact developed a system that allows easy ducting in existing flues (for 24kW models).

For condensing boilers, the novelty is brought about by the low temperatures of the fumes which allow the use of specific plastic materials; however, in the presence of existing 316 stainless steel flues, installed correctly and with gaskets suitable for receiving damp fumes, there are no problems and they can easily be reconnected to the new boilers while it is absolutely not compliant with the use of aluminum flues or smoke pipes . In fact, aluminum is a metal that is not resistant to the acid condensates present in the fumes.

(*) Each Ø50 mm diameter bend decreases the length of the drain by 4m


the use of the condensate drain pump

Baxi

Baxi has designed this kit to collect the condensate produced by condensing boilers for domestic use: the pump allows the creation of condensate drainage systems in the absence of natural drainage near the boiler. The operation of condensing boilers determines the formation of condensate, due to the principle of condensation. This water therefore needs to be disposed of through special drains. If there is no adequate slope and therefore it is not possible to dispose of the condensate by gravity, it is necessary to install a pump that conveys it towards the drains. The pumps used are also equipped with special non-return valves to avoid bacterial contamination due to any stagnation and return of the waste water. The use of buildings avoiding the use of annoying pipes.
