Water quality
As a water heater is constantly flushed with fresh water, there are restrictions to the
maximum flow temperature related to the hardness of the water. The following table indicates
the maximum flow temperatures for different water hardness values. Not respecting these
values can lead to damage of the heat exchanger.

Hot water production
The following table shows the sanitary hot water tapping volumes which can be achieved
with a THISION-L/R40 water heater, based on a cold water inlet temperature of 10ºC.
