4.3 INDOOR UNIT DATA TABLE.
- The data relating to domestic hot water performance 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.
- * Efficiencies refer to the net calorific value.
- The weighted NO
x
value refer to the net calorific value.
