EPG
By default, the
efficiency of the heat recovery of shower water is determined flat rate. By
specifying a custom efficiency one can deviate from this method. Doing so
requires a quality statement to be discussed.
EPG
A correction factor
for the thermal efficiency is determined based on the connection of the shower
heat recovery system.
•Cold gate of the shower mixer: an individual shower heat recovery system is connected to the cold gate of the shower mixer.
•Inlet of the heater: an individual shower heat recovery system is connected to the inlet of the heater.
•Cold gate of the shower mixer and inlet of the heater: an individual shower heat recovery system is connected to both the cold gate of the shower mixer and the inlet of the heater.
•Collective arrangement: various shower heat recovery system are arranged collectively.
