No hot water at the taps although the geyser has power and water. This page covers how we diagnose and repair it on hot water systems in Sandton.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
High concentration of hotels, corporate towers, gyms and cluster developments running commercial heat pump banks on shared storage. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.

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.
