- 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.

- The max. sound level emitted during boiler
operation is < 55dBA. The sound level value is
referred to semianechoic chamber tests with
boiler operating at max. heat output, with
extension of flue gas exhaust system according
to product standards.
