Parkmore · Priority
Calorifier Not Heating in Parkmore
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 Parkmore.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Parkmore is a high-value residential pocket of Sandton, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.

FAQs
Frequently asked questions
What causes calorifier not heating?
The usual causes are failed steam control valve or actuator, steam trap failed closed flooding the coil, scaled or perforated coil, blocked strainer ahead of the valve. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Valve stroke and actuator test; Trap condition test; Coil hydraulic pressure test; Strainer inspection and temperature survey. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
Usually yes, for a short period, but efficiency and component life are both being lost while the fault persists.
Do you attend this fault in Parkmore?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Parkmore falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs.
