Calorifier Not Heating in Beaulieu
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 Beaulieu.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Beaulieu is a high-value residential pocket of Midrand, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.

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 Beaulieu?
Yes. Midrand and Centurion sit between the Johannesburg and Pretoria routes, so attendance windows are usually the shortest of any area. Beaulieu falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs.
