ARISTON CLAS EVO 28 CF EU BOILER Product code: 3300732 Energy label specifications according to the European ErP directive Class C heating energy efficiency Sanitary energy efficiency profile XL Class B Characteristics of heating/DHW operation: For heating and domestic hot water production Open chamber with natural draft Nominal heat input in heating max/min kW 29.5/13.0 Max/min heating thermal power (80°C-60°C) kW 26.7/11.2 Efficiency at nominal heat input % 90.6 Efficiency at 30% of nominal flow % 89.7 Performance stars (dir. 92/42/EEC) ★★★ Heating max/min temperature °C 35/ 85 Max/min domestic hot water temperature°C 36/60 Specific flow rate in DHW (10 min. with ∆T=30°C) litres/min 13.5 Quantity of hot water ∆T=25°C litres/min 15.8 Quantity of hot water ∆T=35°C litres/min 11.3 Supply voltage/frequency V/Hz 230/50 Total absorbed electric power W 62 Degrees of protection of the electrical system IP X4D Dimensions (H x W x D) mm 770/400/315 METHANE power supply Evo class Conventional compact wall-mounted boiler with auto function The Clas Evo wall-mounted boiler is Ariston's solution for domestic comfort; it stands out for its innovative and captivating design and for its small size that makes it suitable for any type of furniture. It is available in the heating and domestic hot water production version in 2 powers: 24 and 28 kW (open chamber) Characteristics: Backlit multifunction LCD screen Continuous modulation high efficiency circulator Arrangement for multi-zone and multi-temperature thermoregulation Arrangement for solar system management Car function and comfort Aluminum finned primary exchanger Arrangement for integration with system configuration through the new Bus Bridgnet® communication protocol Cold water inlet and heating return filters Convenience function: The Comfort function speeds up the delivery of domestic hot water, reducing waiting times down to just 5”. This service can be customized by choosing between two modes of use: COMFORT PLUS (hot water immediately ready every time the tap is opened in just 5 seconds) COMFORT (hot water ready for 30 minutes after the last withdrawal so as not to give up savings) car function: It is truly possible to combine maximum comfort with reduced consumption, thanks to the intelligent management logic of the new boilers and the new technology that governs them. By activating the AUTO function, the Ariston boiler chooses the best operating mode based on the environmental conditions, the connected external devices and the required performance. Impossible to compare this ability to interpret and respond to external stimuli with what has been achieved so far. AUTO does not fear comparisons High efficiency circulator with continuous modulation: It allows automatic adaptation of the power based on the temperature of the system, guaranteeing boiler performance and reducing electricity consumption. Optimization of thermal efficiency. Optimization of comfort with constant temperature. Maximum silence. Product Warranty All products for sale on our site are new and packed. The warranty on this item is 24 months from the date of purchase.
