Unit resistance and PHE resistance by glycol concentrate
The unit is composed of water pipes and PHE basically.
To ensure correct operation and predict the expected performance, Flow and Resistance table can be used and Flow and
Resistance characteristic is dependent on Glycol concentration.

Changing Glycol concentration can cause the pressure drop of the system and it can leads to make flow rate rather slow. Just
in case performance degration, installer shall be careful of flow rate changes.
