Calorifier Not Heating in Randfontein
The calorifier receives steam or hot water but the stored water stays cold. This page covers how we diagnose and repair it on hot water systems in Randfontein.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Mining and industrial sites with boiler plant and bulk hot water requirements. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.
