The pH value and the salt Water heating systems as per DIN EN 12828 content also play a major role. - Page 49 NOTICE! Heat pump systems and components from REMKO must be filled and operated with deionised water (completely desalinated). We also recommend the use of the complete heating protection unit available from us. Full protection with glycol should be used in cooling systems. The system water should be tested each time the plant is serviced, but at least once a year.
