Tax credits and incentives

Antares is an energy class A and energy class A+, in other words the highest energy efficiency level achievable with a boiler.

One model suitable for all situations

Even the most extreme where very low power is required for space heating and at the same time a large quantity of hot water

The modulation of a boiler is the ability to generate a more or less intense burner flame. The modulation ratio therefore indicates the ratio between the maximum and minimum power that can be developed by the burner. In the case of Antares, the maximum power is more than 20 times the minimum. Thanks to its high modulation range (1/21), Antares is a versatile boiler that guarantees:

• High energy efficiency
• High domestic hot water output at 20 L/min @ 25° temperature differential in addition, a low continuous power output results in quiet operation and a longer boiler life.

Hydrogen Ready

For an ongoing commitment to the environment

Among the alternatives to traditional fuels, the use of hydrogen emerges as a promising solution; the combustion of hydrogen can only release water vapour into the atmosphere and minimal quantities of nitrogen oxides: a great advantage from an ecological point of view. In addition, existing infrastructure such as the methane transport and distribution network in Italy can already transport mixtures of methane and hydrogen at 20% by volume. Installing a Hydrogen Ready 20% boiler means preparing for a future less dependent on methane.

There are two advantages for consumers who choose a Hydrogen Ready 20% boiler:

• Investing in an appliance that can have a life of more than 20 years with technology that is ready for future developments in the industry without replacing the generator.
• Invest in a technologically advanced appliance in line with the most advanced solutions for sustainable energy management.

Adaptive Gas Technology

less consumption, more efficiency, less emissions

The innovative Adaptive Gas technology, with which Antares is equipped, allows for completely autonomous adaptation of boilers to different types and qualities of gas. Addition to detecting the flame, the electrode also detects the characteristics of the gas and automatically adapts the parameters of combustion to maintain the highest level of efficiency, resulting in reduced consumption and emissions compared to traditional control systems. The Adaptive Gas system makes the boiler ready to operate with any type of gas without changing any hardware.
