3.24 TECHNICAL DATA.
- e data relating to domestic hot water perfor-
mance refer to a dynamic inlet pressure of 2 bar
and an inlet temperature of 15°C; the values
are measured immediately at the boiler outlet,
considering that to obtain the data declared,
mixing with cold water is required.
- (*) Yields refer to the lower heating value.
