It features a built-in stainless steel tank and is available in two models: 25 kW with a 45-litre tank and 32 kW with a 60-litre tank. The boiler is engineered to optimize energy use and reduce emissions, making it environmentally friendly.

Specifications: The boiler includes a condensing heat exchanger made from extruded aluminum for enhanced thermal transfer and durability. It operates with a premix burner that minimizes NOx emissions, achieving Class 5 under European Directive EN 483. The efficiency is rated at up to 102.7% at partial load, with a nominal output efficiency of up to 98.3%.

Key Features:

Condensing Heat Exchanger: Offers high thermal conductivity and corrosion resistance.
Built-in Tank: Stainless steel with magnesium anode for protection against stray currents.
S.A.R.A. System: Automatic Temperature Control for energy efficiency and comfort.
Range Rated Certification: Allows power adaptation to actual thermal needs, reducing gas waste.
Low NOx Emissions: Environmentally friendly, Class 5.
User-Friendly Controls: Ergonomic knobs and digital display for easy operation.

Performance: The boiler can supply up to 141/183 litres of domestic hot water in 10 minutes with a ΔT of 30°C. It features a high-efficiency premix burner and a condensing heat exchanger that recovers latent heat, achieving a ★★★★ efficiency rating according to the European Directive EEC 92/42.

Safety and Reliability: Equipped with safety devices such as flame detection, flue evacuation checks, and anti-blocking functions for the circulation pump and three-way valve. Supports climatic thermoregulation and compatibility with Beretta remote control panels.

Technical Data: Operates at a maximum pressure of 3 bar and a temperature range of 20/45 - 40/80°C for central heating. DHW production rates are 14.3/11.9/10.2 l/min for the 25 kW model and 18.3/15.3/13.1 l/min for the 32 kW model. Dimensions are 940x600x462 mm, with a net weight of 66 kg for the 25 kW model and 70 kg for the 32 kW model.
