Boiler Not Producing Steam in Randburg
The boiler fires but pressure will not build to the operating setpoint. This page covers how we diagnose and repair it on steam systems in Randburg.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Large stock of 1970s–1990s homes with ageing 150–200 L geysers, plus a spread of small commercial and light industrial units along Malibongwe. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.

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.
