Important Information – Water Treatment / Corrosion Inhibitor
To keep your radiator working efficiently and to maintain your guarantee, we recommend that all heating systems are properly cleaned and treated before installation. This means flushing the system with a cleaning agent and then adding a central heating inhibitor.
This step is especially important if the radiator is being fitted to an older or existing system, as it helps prevent corrosion and ensures long-term performance.
Please note: not following these steps may affect the radiator’s guarantee
