Constant DHW output
The constant outputs shown refer to the following
parameters:
• Flow temperature 90 °C
• Outlet temperature 45 °C
• Cold water inlet temperature 10 °C
• Maximum heat input (heat source input at least the
same as the cylinder coil output)
Reducing the specified heat input will result in a
reduction in the constant output and the performance
factor (N
L
).
