Professional diagnosis for Heat Tech geysers that will not ignite, shut down, produce unstable water temperature, leak, display errors or fail to heat. Repairs and installations are available across Gauteng.
Heat Tech units can develop faults related to ignition, gas supply, water flow, batteries, sensors, burners, heat exchangers, thermostats, elements, pressure valves or installation conditions. The symptom alone does not prove which component has failed, so professional testing is preferable to replacing parts by guesswork.
Possible causes include depleted batteries, insufficient water flow, low gas pressure, a closed valve, ignition electrode faults, blocked burners, damaged wiring or sensor problems. Stop using the system and request assistance if you smell gas or see abnormal flame behaviour.
Temperature fluctuation may be caused by mixer-tap behaviour, changing water flow, incorrect gas regulation, scale, an undersized unit, sensor faults or a system installed outside its operating requirements.
We assess flame detection, exhaust and ventilation, water-flow stability, temperature protection, gas delivery and model-specific controls. Repeated reset attempts should not replace a safe diagnosis.
Our service includes fault finding, approved component replacement where available, burner and ignition inspection, water-flow checks, temperature testing, safe installation and applicable compliance documentation. We also advise when age, corrosion or unavailable parts make replacement more economical.
