EOLO Star
- GENERAL FEATURES
EOLO Star is a wall-hung boiler with sealed chamber and forced draught for central heating and the
production of domestic hot water.
The boiler. distinguished by compact dimensions (H=785 mm. W=450 mm. D=250 mm), has a
working power of 20.000 kcal/h (23.3 kW).
Adjustment and control of the boiler (burner ignition. temperature adjustment. flame modulation.
antifreeze up to – 5 ºC) are entrusted to an microprocessor-controlled electronic board which, by means
of two LEDs, displays boiler operation and performs diagnostics in the event of faults.
The hydraulic circuit features a bithermal type copper water-gas exchanger for the production of hot
water, an automatic system by-pass and a flow meter for tapping the hot water.
Combustion air intake inside the sealed chamber and the expulsion of gases are ensured by a fan. the
correct operation of which is controlled by a pressure switch.
