The Ariston Alteas ONE+ NET is Italy's flagship wall-hung condensing combi boiler, combining 94% seasonal efficiency, A+ ErP energy rating, and built-in Wi-Fi connectivity in a single ultra-premium unit. Housed behind a Ultrasafe black glass front panel, this 30 kW or 35 kW boiler ships complete with the Cube RF wireless modulating room sensor, the standard horizontal flue kit, and full Ariston NET smartphone app readiness — genuinely Boiler Plus compliant straight from the box. Compatible with 20% hydrogen blends and auto-calibrating between natural gas and LPG without a conversion kit, it is the definitive choice for high-demand homes where design, intelligence, and long-term reliability are non-negotiable.
Ariston's patented XtraTech™ stainless steel heat exchanger features wider waterways than conventional aluminium alternatives, reducing limescale accumulation risk and improving thermal transfer. TÜV Rheinland-certified performance underpins the 12-year component warranty.
The included Cube RF wireless thermostat is a load-compensating modulating controller — it continuously adjusts boiler output based on how far the room is from target temperature, rather than switching on/off at full power. This is what delivers the A+ ErP rating in practice.
An embedded Wi-Fi gateway connects directly to the Ariston NET smartphone app, enabling remote heating and hot water control, schedule programming, fault notification, and Internet Weather Compensation — where the boiler adjusts flow temperature based on live outdoor conditions.
The Combustion Control System detects gas type at commissioning and self-calibrates — the boiler can run on natural gas or LPG without a conversion kit. This simplifies stock management and makes the unit suitable for off-grid or rural properties.
A 1:10 modulation ratio means the boiler can turn down to 3.1 kW minimum output on heating — critical for well-insulated homes where gross oversizing causes short-cycling. Advanced Data Science diagnostics log operational data to aid fault-finding and reduce service time.
AUTO function learns occupancy patterns and pre-heats accordingly. COMFORT mode keeps the DHW circuit primed to reduce draw-off wait time. CARE mode provides frost protection and pump exercise. All programmable via the backlit touch display or Ariston NET app.
