Heating water or hot water tank

Why should I have the feed water of my heating system or my hot water tank analyzed? The analysis makes it possible to know the aggressive and corrosive nature of the water. Aggressive water corrodes materials and facilitates degradation or even piercing of metallic elements.

Description of the analyzes carried out by the laboratory

pH : Used to control the acidity or alkalinity of a water. A low pH (acidic) may cause degradation of the metallic elements. A high (basic) pH promotes lime deposition

Conductivity : Information on the mineralization of water, the higher the value the more the water is loaded with mineral salts.

Alkalimetric Title - Complete Alkalimetric Title (TA-TAC) : Translate the carbonate alkalinity of a water. 

Equilibrium pH and TAC : Indicate the pH and TAC value so that the water is neither aggressive nor encrusting (chemically neutral water)

Total hardness (TH or hydrotimetric title) : Corresponds to the presence of calcium and magnesium in water. High hardness promotes scaling, low hardness promotes corrosion.

Chlorides : A high concentration of chlorides promotes corrosion of metal installations

Sulfates : A concentration higher than 300 mg / l accelerates the corrosion phenomena of metallic installations

Iron : A significant presence in water can come from the degradation of metallic elements. The red coloration shows a high concentration of iron

Suspended matter : Used to assess the sludge rate of the installation

Larson and Leroy indices : These indices make it possible to estimate a correctness compared to non-ferrous materials
