NIKE Star E

Wall-mounted instant boilers NIKE Star E is the wall-hung boiler that Immergas has designed expressly for applications in new buildings, thanks to its noteworthy construction simplicity and particularly small overall dimensions (only 24 cm depth). The reduced dimensions also allow installation inside kitchen cabinets or in limited spaces generally: the casing has a unique body allowing to simplify assembly and disassembly of the same. It is a version with instantaneous production of DHW, with open chamber and natural draught, it has a bithermal rapid heat exchanger, which allows to quickly take the DHW to temperature at the time of withdrawal, thanks to its direct heating. NIKE Star E is equipped with a P.C.B. with microprocessor and control panel, complete with display, buttons for adjustment and settings of the boiler's main parameters. The boiler distinguishes itself also due to the possibility of coupling, by the means of just two wires, to the new Digital Remote Control (optional), which allows the remote control of the boiler controls and integrates a flow temperature modulation function and boiler self-diagnostics among the others. The appliance has IPX4D electrical insulation rating: this means that the boiler is protected against jets of water and high humidity levels.

NIKE/EOLO STAR
COMPACT DIMENSIONS AND ADVANCED FUNTIONALITY
Immergas, leader company in the production of wall-hung boilers, presents the new range of traditional combi instantaneous boilers NIKE and EOLO Star 24. The Star range is characterised due to extremely compact dimensions, modern and elegant design, high performances and advanced functionality. NIKE and EOLO Star feature 24 kW heat output, both in the heating and in the domestic hot water production functioning. The NIKE model is a conventional flue boiler, while the EOLO version is a fan assisted one.
FAST DOMESTIC HOT WATER SUPPLY
The Star range is equipped with a bithermal heat exchanger and integrates both the heating and the sanitary hot water production circuits. Therefore the heat exchanger guarantees fast hot water supply and considerable simplification of the hydraulic circuit, in favour of reliability and maintenance easiness.
NIKE/EOLO STAR COMPACT DIMENSIONS ITALIAN DESIGN DIGITAL DISPLAY BITHERMAL EXCHANGER

EXTREME VERSATILITY

Star boilers are equipped with a compact hydraulic group, realized by Immergas to meet all modern system exigencies, incorporating an automatic by-pass particularly useful in case of systems with thermostatic or zone valves. Moreover the fan assisted model EOLO gives the possibility to use the openings positioned on both sides, to the right and to the left of the concentric flange, for the combustion air intake. The installation procedures are made extremely easy thanks also to the reduced weight of these boilers and to their functional accessory kits.
INNOVATIVE CONTROL PANEL FOR TOP ERGONOMICS
NIKE and EOLO Star 24 boilers are praised for their modern and functional design, while with a depth of 24 cm only they can be absolutely regarded among the most compact boilers, making it possible to place them inside any wall cupboard. The boilers aesthetics is highlighted by the innovative digital display of the control panel, ensuring a simple and intuitive use of the boiler while allowing to keep all the main operating information, set temperatures and use parameters always under control. The electronics equipping the Star models allows for the combination with the Digital Remote Control (CRD); this device allows to control the boiler at a distance while increasing its energy performances, thus guaranteeing maximum home comfort and remarkable money saving.
