Gas Boiler Not Igniting in Melrose Arch
The boiler attempts to start, clicks or purges, then locks out without lighting. This page covers how we diagnose and repair it on boilers in Melrose Arch.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Melrose Arch is a high-value residential pocket of Rosebank, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.

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.
