GAS BOILER JUNKERS CERACLASS EXCELLENCE ZWC 28-3 MFK METHANE OPEN CHAMBER - ErP Technical features Declared load profile XL Nominal heat output: 28 kW Nominal heat input: 31.3 kW Continuous sanitary production: 13.4 l/min Sanitary temperature range that can be set: 40/60°C Useful thermal efficiency at nominal power: 90.5% Useful thermal efficiency at 30% nominal load: 89.6% NOx class: 3 Degree of protection: IP X4D Version: CNG Important information External installation, in a partially protected place in compliance with current legislation, Natural draft boilers programmed to be connected exclusively to multiple flues for several homes, for the escape of smoke due to combustion outside the room in which the boiler is installed. The boiler draws the combustion air directly from the installation room and is equipped with an anti-wind chimney. ZWC 24-3 MFK E, ZWC 28-3 MFK E are characteristics of wall-hung open chamber boilers with natural draft, with micro-accumulator for the production of domestic hot water. General characteristics CERACLASSEXCELLENCE is the JUNKERS boiler designed for heating and domestic hot water production. Easy to use and low consumption make it one of the best boilers to guarantee maximum comfort. Furthermore, by pressing the COM/ECO function, hot water can be managed in a simple way.  Functions: Managed with Bosch Control CT100 (accessory), digital modulating room thermoregulator, with soft touch display that can be positioned on the wall, with an elegant and refined design; accompanied by a smart and functional app. Primary and secondary heat exchangers. Circulator in Energy Class A; 8 liter expansion tank (10.5 liters for ZWC 35); Dynamic microstorage tank with domestic hot water pre-heating function; Heating filling cock (in the boiler); Continuous power modulation; Bosch Heatronic 3® module, BUS system, with multifunction display; Antifreeze for the heating circuit and antiblock for the circulator; Patented passive solar optimization algorithm SolarInside-ControlUnit; Possible remote management via MB LAN or Netcom 100 modules (accessories) which can be combined with CR100 or CW thermoregulators.
