3.20 TECHNICAL DATA.
- Flue temperature values refer to an air inlet
temperature of 15°C and delivery temperature
of 50°C.
- The data relevant to domestic hot water
performance refers to a dynamic inlet pressure
of 2 bar and an inlet temperature of 15°C; the
values are measured directly at the boiler outlet
considering that to obtain the data declared
mixing with cold water is necessary.
- (***) Yields refer to the lower heating value.
- (*) Specific capacity “D”: domestic hot water
flow rate corresponding to an average increase
of 30K, which the boiler can supply in two
successive withdrawals.
- (**) When the boiler is connected to an external
storage tank.
