With the hydraulic connection, it must be ensure that the correct flow
directions are adhered to. At the condenser, the in-flow is at the bot-
tom (heating water return to heat pump).
The temperature spread of 3-4 K at the heat source and 5-
10 K at the heat drop must be maintained under normal operating
conditions while observing the application limits. This spread is nor-
mally achieved when the volume flows specified in the technical da-
ta are observed.
In comparison to conventional combustion systems, heat pumps
operate with larger mass flows. This results in larger pipe diameters
and relevant pump configurations.
CAUTION!
Device damage through improper system setup!
Water and/or glycol mixture can leak.
Therefore:
-
In the brine system, as well as on the heating side,
safety devices and expansion containers must be
installed.
