Boiler Not Producing Steam in Douglasdale Ext

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 Douglasdale Ext.

This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.

Douglasdale Ext is an extension of Fourways with a mix of original and renovated housing, so geyser positions, pressure control and pipework standards vary stand to stand. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.

How do you diagnose it?

Combustion analysis at high fire; Blowdown valve inspection for passing; Feedwater temperature logging; Fireside and waterside inspection. The readings are recorded so the repair decision is based on data.

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.
