Kya Sand is a high-value residential pocket of Randburg, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.

FAQs
Frequently asked questions
What causes boiler flame failure?
The usual causes are dirty or cracked flame rod, failed uv scanner, poor earth on the flame sensing circuit, incorrect air/fuel ratio. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Flame signal measurement in microamps; Earth continuity test; Combustion analysis through the firing range; Gas pressure under load. 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.
Do you attend this fault in Kya Sand?
