- Flue temperature values refer to an air inlet
temperature of 15°C and flow temperature of
50°C.
- The data relevant 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 directly at the boiler outlet consider-
ing that to obtain the data declared mixing with
cold water is necessary.
- * Yields refer to the lower heating value.
- ** Specific flow rate ''D'': domestic hot water
flow rate corresponding to an average tem-
perature increase of 30K, which the boiler can
supply in two subsequent withdrawals.
