Heating system protection

This category includes chemical products for the long-term protection of closed heating circuits - boilers, radiators, underfloor heating and heat exchangers. Cetamin and ISOFT powder chemicals reduce corrosion of the system's metal parts, limit sludge and limescale formation, and maintain optimal chemical stability of the heat-transfer fluid.

The products are dosed directly into the heating water when filling or topping up the system, or during regular maintenance. The choice of product type (e.g. F300 vs. F360, OB vs. NB) depends on the pipe and appliance materials in the circuit, the hardness of the fill water and the boiler manufacturer's recommendation.

Frequently asked questions

• Why protect a heating system chemically? Without water treatment, a closed circuit suffers corrosion of metal parts and sludge formation, which reduces boiler efficiency, clogs heat exchangers and shortens the service life of circulation pumps.
• When is the product dosed? Most often when the system is first filled, or after it has been drained and refilled; periodic concentration checks are recommended for long-term operation.
• Is there a difference between the F300 and F360 variants? They differ in the concentration of active substances and the recommended dosing ratio according to system volume - the exact ratio is given in the technical data sheet of the specific product.
• Can the chemicals also be used in systems with aluminium parts? Yes, both ISOFT and Cetamin products are suitable for multi-material systems including aluminium, copper and steel - check the specific compatibility in the technical data sheet.
