John Thompson Gas Boiler Repairs in Crowthorne
John Thompson gas boiler repairs in Crowthorne. Locally manufactured industrial plant with strong local parts support.
John Thompson equipment we work on includes packaged steam and hot water boilers. Commonly replaced parts on this brand are level controls, burners, refractory, and we keep or source these against the unit's model and serial plate rather than by guesswork.
Gas boiler repairs concentrate on the ignition and flame supervision chain: gas train, solenoids, ignition transformer, electrode gap, flame rod or UV cell, and the air proving switch. Lockouts are a symptom; the fault is normally in gas pressure, air proving or a dirty sensing path.
Crowthorne 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. Crowthorne falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.
