Geyser Thermostat Replacement in Randburg

One of our customers in Northcliff had the opposite problem. Their geyser was boiling nonstop. We opened the panel, and sure enough, the thermostat had failed in the "on" position. The element was red hot, the water was scalding, and their electricity bill had doubled. We replaced the thermostat, reset the temperature, and things were back to normal.

A faulty thermostat doesn't just waste power — it can be dangerous. We sort it out quickly, safely, and properly.

The thermostat is the brain of your geyser. It tells the element when to heat and when to stop. If it sticks, burns out, or misreads the temperature, you get:

• No hot water
• Water that's too hot
• Water that runs hot then cold
• Geyser that keeps tripping the power

We test the thermostat, inspect the element, and check the thermal cut-out switch too. If one part is faulty, we replace it. If multiple parts are worn or scorched, we'll quote for both. No surprises.

We carry the most common thermostats and elements in our vans. That means most repairs are done on the spot — same day. We work on Kwikot, Heat Tech, Franke, and other local brands.

If your geyser is safe to open, we'll test the thermostat in place. If not, we isolate the unit, drain what's needed, and work cleanly and carefully.

In Fairland, one client's geyser tripped the DB board every night. The thermostat insulation had burned through and was shorting against the tank. Replacing it fixed the issue completely.

We don't leave until we're happy with the heat levels, safety, and shut-off points.

Sometimes the thermostat is just part of the problem. If your geyser is:

• Leaking from the overflow or pressure valve
• Making strange popping sounds
• Not holding temperature

…it might need more than a thermostat. We handle full geyser repairs across Randburg, including pipework, valves, elements, and electrical faults.

If the geyser is old or unsafe, we'll explain the risks and give you options. One Northcliff home had a geyser with exposed wiring in the roof. We didn't just fix the thermostat — we rewired the whole panel and made it safe.

We don't patch and run. We fix things properly.

Some geysers aren't worth saving. If the tank is rusted or leaking, or if the repairs cost more than a new unit, we'll say so. We can supply and install a new geyser same day.

We install:

• High-pressure and low-pressure units
• Inside ceiling or outside wall brackets
• 100L, 150L, and 200L tanks
• Proper drip trays, valves, and supports

Our installations follow SANS standards — no shortcuts.

We've replaced geysers all across Randburg — from Fairland double-storeys to modern Northcliff clusters. We do neat work, clean up after ourselves, and test everything before we go.

Randburg is full of homes from different eras — old council houses, new builds, and everything in between. Geysers in older homes often have outdated thermostats and elements. Some don't even have drip trays or shutoff valves.

We know what to expect in Fairland homes — long pipe runs, older insulation, and low roof space. In Northcliff, it's often electric faults or bad workmanship from previous repairs.

We're local. We've seen these problems before. We know how to solve them without drama.
