Hi-Therm® System Refill
What to do if you need to top up after having Hi-Therm® installed?
If you have had Hi-Therm® installed in your central heating system, you have the comfort of knowing that your system is both protected from corrosion, operating in a cost-efficient manner and reducing your homes carbon footprint.
To maintain that protection and efficiency it is important that Hi-Therm® concentration does not dilute by more than one litre, i.e. do not dilute by the inclusion of additional water or any form of inhibitors.
To protect your system and your warranty we recommend that you call our helpline (01562 540040) prior to modifying, maintaining, or servicing your heating system.
