CAESAR Star technical details.
- The exhaust flue temperature values refer to
incoming air temperature of 15°C.
- The data relating to the d.h.w. supply refer to a
dynamic inlet pressure of 2 bar and an incoming tem-
perature of 15°C; these values are read immediately
at the water heater outlet considering that to obtain
the declared values mixing with cold water is
required.
- The combustion details refer to a thermal power
below 15°C and to a pressure of 1013 mbar.
