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.
* The efficiency values refer to the lower calorific value.
The weighted NOx value refer to the net calorific value.
