Chemicals
Chemicals for heating systems protect the piping and components against corrosion and deposits, or serve to flush the system before or after an intervention. Inhibitors (e.g. C1) extend the service life of the system, cleaners (C3, C7) remove deposits, and C4 is a liquid sealant for minor leaks.
