Also available : Boiler antifreeze safety Primary circuit thermal inertia disposal. Primary exchanger ACTA NOX features a water-cooled burner which allows to achieve high efficiency combustion and to limit the emissions of polluting substances. The burner is therefore characterized by a flame at a lower temperature than traditional boilers, which reduces the production of nitrogen oxides. Even the shape of the flame is specific to the water-cooled burner, in fact, it presents the flame in a uniform manner and with a reduced height. This makes ACTA NOx the SAVIO product that satisfies the needs of maximum domestic comfort and respect for polluting emissions. Secondary exchanger ACTA NOX is available in a mixed version for heating, domestic hot water production: the hot water is supplied at an adjustable and constant temperature thanks to the electronic modulation of the boiler.

    IMMERGAS Immergas Boiler Open Chamber Nike Eco 24 Methane Low Nox 3.028476 - New

    Immergas Open Chamber boiler NIKE ECO 24 Methane low NOx 3.028476 - NEW Heating class C Sanitary Class B XL load profile Maximum nominal heat input kW (kcal/h) 26.6 (22,882) Minimum heat input in DHW kW (kcal/h) 9.6 (8,251) Minimum useful heat output in domestic hot water kW (kcal/h) 8.5 (7,310) NOx class 6 Specific flow rate in continuous domestic hot water service (∆t 30 °C) l/min 11.2 Nominal heating expansion vessel capacity (total) liters 10 (8.0) Electrical protection degree IP X5D NIKE ECO From 26 September 2018, even type B appliances with an open chamber and natural draft must comply with the maximum NOx emission limit of 56 mg/kWh. Precisely to comply with the ErP Directive 2009/125/EC on energy efficiency, Immergas has renewed the range of traditional boilers with the new NIKE and AVIO ECO models. The NIKE is instantaneous and AVIO has an integrated 45 liter storage tank. Both boilers have 24 kW of power, can only run on methane and are ideal for replacing old boilers in the presence of branched collective flues (in fact, they comply with the values ​​required by DI 26/06/15 "Minimum requirements", in case of mere replacement of the generator). With the low-consumption circulator and the ecological burner both as standard, NIKE and AVIO ECO contribute to raising the energy efficiency class in space heating and in the production of domestic hot water. For this they can enjoy the tax deductions currently in force in the event of replacements, for building renovations and interventions aimed at saving energy on existing buildings. The range can also be remote controlled by DOMINUS, the simple and intuitive app that allows you to check the functioning and temperature of the boiler, turn it on and off from anywhere via smartphone or tablet. ECOLOGICAL BURNER Designed to minimize the inflow of secondary air and cooled by the system return water pipe, it ensures high thermal performance, low emissions of carbon monoxide (CO) and nitrogen oxides (NOx). CLASS A CIRCULATOR The low-consumption circulator allows for considerable savings in electricity compared to a traditional circulator and adjusts its performance based on the variations in the hydraulic flow rate of the system, for example in the presence of thermostatic valves or zone valves. LOW ELECTRICITY CONSUMPTION IN STAND-BY (LESS THAN 6 W) EASY TO USE The intuitive control panel allows you to easily set the domestic hot water and heating temperatures. A series of information is displayed on the backlit LCD display, including the operating status of the boiler, the temperatures and any anomalies. ATTACHMENTS UNCHANGED Thanks to the unchanged connections, installation is quick, even when replacing with other similar wall-mounted models in the Immergas range. IPX5D ELECTRICAL INSULATION DEGREE Product Warranty The warranty on this item is 24 months from the date of purchase.
