Custom efficiency

 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.

Connected to

 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.
