Constantia Kloof · Priority
Calorifier Not Heating in Constantia Kloof
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 Constantia Kloof.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Constantia Kloof sits within the Randburg belt, with larger stands, long hot water runs and frequent pool heating. Static pressure and dead-leg length are checked as part of any hot water complaint here. 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 Constantia Kloof?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Constantia Kloof visits carry heat pump and geyser spares together, since both are commonly installed on the same property.
