John Thompson Gas Boiler Maintenance in Alexandra
John Thompson gas boiler maintenance in Alexandra. 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 maintenance keeps combustion inside the manufacturer's stated band and proves the gas train is tight. On condensing plant it also keeps the condensate path and secondary heat exchanger clear, which is where efficiency is usually lost first.
Dense residential area with electric geysers and community hot water installations. Fast attendance from the nearby Sandton and Wynberg areas. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.
