Question

I keep getting Overheat Red on my Alde Heating system control panel?

Answer

This is likely that you have a too strong ratio of the antifreeze or too weak. We recommend replacing the antifreeze well within its lifespan with Alde G13 antifreeze. If you leave it too long then the antifreeze will degrade resulting in overheating issues. Also, if you have mixed the antifreeze with water yourself and the ratio is more than 65% then this again will result in overheating issues.
