(*) This yellow line shows the by default values as used by UF 801-P
for caloric heat flow calculation.
Additive as ethylene glycol in mixture with water can slightly change
above values..
Avec If the energy / heat flow carrier is oil, it is necessary to
compensate with the ratio of the two products Water / Oil.
