Gas Boiler Not Igniting in Atholl Gardens
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 Atholl Gardens.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Atholl Gardens sits within the Sandton belt, with larger stands, long hot water runs and frequent pool heating. Static pressure and dead-leg length are checked as part of any hot water complaint here. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
