Technical data.
EOLO Star 23 kW technical data.
- The flue temperature values refer to an air inlet temperature
of 15°C.
- Data relative to d.h.w. performance refer to a dynamic inlet
pressure of 2 bar and an inlet temperature of 15°C; these
values are measured at boiler outlet considering that to find
these declared values mixing with cold water is necessary.
