Performant double-circuit gas boiler for wall mounting. Able to provide hot water and heating in a detached house or a spacious apartment with a total area of up to 158 m². Designed for wall mounting, it has a proven classic hydraulic circuit. Equipped with two separate heat exchangers for heating circuits (copper) and hot water circuits (stainless steel). It is positioned as a product of the middle price category. The closed combustion chamber with forced exhaust of flue gases with the help of a turbofan makes it possible to dispense with a special boiler room and install it in a residential area. The Airfel Digifel Duo 18 CE boiler is equipped with a high-quality low-noise three-speed pump and a modern digital control system. It is possible to connect a remote room thermostat and an outd...oor air temperature sensor, which are purchased separately. Able to prepare up to 10.2 L / min of hot water (at an inlet-outlet temperature delta of 25 °C). At the same time, the maximum temperature of hot water is 55 °C, which is completely safe for children. The boiler is able to operate in a fully automatic mode, reliable electric ignition and step modulation of the flame allow you to optimize the heat output and significantly reduce gas costs. Equipped with all necessary protective systems.
