THE HEATING FLUID
In case water is used as heating fluid, in order to limit corrosion phenomena on the external side of the tubes, the water itself shall have the following specifications: Ph degree <= 10,5 Hardness in French degrees <= 22° Free oxygen <= 800 micrograms / liter Copper <= 80 micrograms / liter The use of corrosion inhibitors or antifreeze fluids must be carried out in compliance with the prescriptions provided for by the manufacturer of such fluids. More strict limits may be imposed by the manufacturers of other components placed on the production circuit of the heating fluid.
