Heating return increase for multiple systems (Installation 4)
Installation with more than one Power Unit
The installation consists of multiple XRGI systems and an additional heat source.
For the operation of the installation it is necessary that the building‘s heating circuit is regulated, i.e. that hot water is not led
back to the XRGI system.
The XRGI systems are connected to the storage tank. The circulation pumps of the Q60-Heat Distributor pass the heat pro-
duced to the storage tank. A flow pump (not included) must be installed to ensure there is flow from the storage tank. f There
must be a direct flow connection to the additional heat source.

Heating return increase with Flow Control (Installation 3)
Installation with one Power Unit
Installation 3 consists of one XRGI system and an additional heat source.
In installation 1, the XRGI system is equipped with a Flow Control (not included). The Flow Control regulates how much heat is
fed in the building's heating system and how much is stored in the storage tank. The XRGI system is connected to the return
pipe of the building‘s heating system. There must be a direct flow connection to the additional heat source. With this installati-
on, the XRGI system takes as much water as it requires and passes the rest to the additional heat source.
