Wall-mounted condensing boiler for external installation, with a configuration ratio of 1:7, XtraTech ™ Heat Exchanger and Auto and Comfort functions.
Dimensions (H X W X D): 770X505X240mm
ENERGY EFFICIENCY
Class A+ in heating thanks to thermoregulation.
The "AUTO" function avoids temperature fluctuations, thus ensuring reduced consumption.
DESIGN AND TECHNOLOGY
New XtraTech ™ * stainless steel heat exchanger exclusively from Ariston with flow sections +142% compared to previous version.
It includes the Sensys system manager and the external sensor, which allows the boiler operation to be adjusted according to the external temperature.
Sensys Net also allows a complete system capability, being able to communicate all the components of your system, thanks to the Bus Bridgnet® communication protocol.
The semi-automatic filling system detects the lack of water, and restores the water pressure after the intervention of the end user.
Exhaust 80, 60, 50 mm
COMFORT
Very precise power regulation according to the actual heating need thanks to the 1:7 modulation ratio.
Ignition system, electronic combustion control.
"Comfort Mode" gives instant hot water, for 30' after the first draw, eliminating waiting times.
QUALITY
Clas One Ext is manufactured with the best materials available: the stainless steel used guarantees high fidelity and a very long life cycle.
The proportional fan gives a very constant air supply for a good combustion.
The addition of a heating return filter guarantees the protection of the boiler against the accumulation of water impurities, as well as the venting function protects against the accumulation of air.
The use of anti-sticking systems prevents frost and scale accumulation not only in the boiler but also in the entire system.
The corrosion-resistant electro-galvanized steel casing protects the boiler from the weather.
