Initial DHW output
For DHW heating from 10 to 40 °C
*3 If the gas supply pressure is higher than the maximum permissible value, install a separate gas pressure governor upstream of the sys-
tem.
*4 At 70 ºC average boiler water temperature and cylinder storage temperature Tcyl = 60 ºC.
DHW performance factor NL depends on cylinder storage temperature Tcyl.
Standard values: Tcyl = 60 ºC → 1.0 × NL Tcyl = 55 ºC → 0.75 × NL Tcyl = 50 ºC → 0.55 × NL Tcyl = 45 ºC → 0.3 × NL.
