Boiler Not Producing Steam in Duxberry
The boiler fires but pressure will not build to the operating setpoint. This page covers how we diagnose and repair it on steam systems in Duxberry.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Duxberry 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. 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 boiler not producing steam?
The usual causes are burner not reaching high fire, excessive blowdown or a passing blowdown valve, feedwater temperature too low, scaled tubes reducing heat transfer. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Combustion analysis at high fire; Blowdown valve inspection for passing; Feedwater temperature logging; Fireside and waterside inspection. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
No — isolate the plant and call 069 268 0988. Running it in this condition risks further damage or an unsafe situation.
