General Features

BLUEHELIX MAXIMA



The exclusive lines of BLUEHELIX MAXIMA radically innovate the aesthetic concept proposed until now through the use of crystal and the revolutionary use of curved shapes. A multicolored LED environment, embedded in a central position, allows the boiler's status and operating modes to be perceived even through visual color. The large 7" full color touch screen display integrated into the tempered black glass front surface allows the user to interact in a totally smart way with the product, also thanks to the combination with the smart CONNECT remote control, managed via an iOS and Android app. Designed to fully satisfy the needs of a "robust" product in every respect: high-passage primary heat exchanger, enhanced 20-plate secondary domestic hot water exchanger, high-head circulator, new control electronics. All these elements are designed to ensure maximum efficiency and reliability over time, even when replacing old generators in particularly dirty systems: ideal for "worry-free" replacement.

MAXIMUM SILENCE: ONLY 45 dB
The meticulously designed BLUEHELIX MAXIMA has achieved significant levels of silence and acoustic comfort, so much so that it's almost difficult to distinguish the background noise in a home from the noise produced by the boiler during full operation. The boiler's on/off transients have also been optimized for acoustic comfort, so customers no longer have to worry about knowing whether the boiler is on or off based on its noise, as was the case with older generations of boilers.

MAXIMUM INNOVATION
Developing sustainable, low-impact solutions to combat global warming is now a reality! BLUEHELIX MAXIMA is already capable of self-regulating (plug-in) and operating correctly and safely with hydrogen-enriched natural gas blends already available for distribution in Europe (*).

BOILER CONTROL
The innovative control and management electronics of BLUEHELIX MAXIMA are among the best in their category. The large 7" full-touch color graphic display allows real-time viewing of operating information thanks to simple and intuitive graphic screens. With a simple touch, you can set the temperature set points for heating and domestic hot water. Thanks to contextual guidance, BLUEHELIX MAXIMA directly informs the user of possible causes of malfunctions while also providing the qualified technician with suggestions for possible solutions. Even system pressure is no longer a concern because, thanks to the semi-automatic system electrocharging function, a simple "touch" is enough and the boiler automatically restores the appropriate pressure without requiring manual intervention by the user.

CONNECT Remote control
* Remote control supplied with the kit code in class A+ for managing home comfort also from a Smartphone (*)

TOP EFFICIENCY EVEN ON OLD SYSTEMS (REPLACEMENTS)

The geometry of the BLUEHELIX MAXIMA THERMOBALANCE™ thermal unit exchanger (figure A) allows operation at almost maximum design efficiency even in partially clogged conditions, while with the same quantity of deposits and sediments (e.g. due to installation on old systems) the traditional exchanger in figure B tends to clog much more quickly in the part in contact with the flame due to the reduced fluid passage area, in which a real barrier of deposits* is formed which hinder heat exchange and reduce efficiency below nominal values.

THE ENHANCED HYDRAULIC GROUP

All models in the BLUEHELIX MAXIMA series are equipped with a 20-plate enhanced domestic hot water plate exchanger and a 7.5 mWc enhanced heating circulator.
The significantly increased cross-section of the 20-plate exchanger compared to a traditional one (e.g., 14 plates) significantly reduces clogging over time, even in particularly hard water, significantly increasing its average lifespan and minimizing maintenance costs. The enhanced system circulation pump with a 7.5-meter head allows all BLUEHELIX MAXIMA models to operate properly, delivering all the necessary power even in systems with high pressure drops (particularly large new systems or older systems with scaling).

MC2 : MULTI COMBUSTION CONTROL

The electronics control the flame ionization current to ensure optimal combustion as air density or gas quality varies. The relationship between the air/gas ratio (λ) and the flame ionization signal is used to control the air/gas ratio itself and therefore combustion. MC2: Multi Combustion Control, the new combustion system with patented gas-adaptive technology, improves adaptability to changing gas network conditions (e.g., fluctuations or reduced pressure). Furthermore, the new control electronics allows for high modulation ranges of up to 1:12 for the 34C model. This allows BLUEHELIX MAXIMA to adapt to the actual power required by the system with extreme ease and efficiency, avoiding annoying on/off operations that increase operating costs and reduce the average life of the product.
