COMFORT
Maximum quietness and acoustic comfort will be in your home. The Alteas One has a new optimized muffler, panel sound insulation, and very few cycles thanks to the full analog modulation pump.
Very precise power regulation according to the actual heating need thanks to the 1:10 modulation ratio.
The AUTO mode avoids temperature fluctuations and peaks, giving a constant temperature for maximum thermal comfort.
"Comfort Mode" gives instant hot water, for 30' after the first draw, eliminating waiting times. More hot water is delivered thanks to the large hot water exchanger.
QUALITY
Alteas One Net is manufactured with the best materials available: stainless steel, used in both heat exchangers guarantees high fidelity and a very long life cycle.
The addition of a heating return filter guarantees the protection of the boiler from the accumulation of impurities in the water.
The use of anti-sticking systems prevents frost and scale build-up protecting not only the boiler but also the entire system.
External combustion analysis port allows easy control of combustion quality.
The built-in low pressure sensor protects the boiler in low water pressure conditions.
