Common Hot Water Faults We Fix
Losing your hot water is a major disruption — especially in winter. Most hot water faults in Woking homes come down to a failed immersion heater, a faulty thermostat, or a stuck motorised valve. The good news is these are all repairable on the same visit in most cases.
No hot water at all
Failed immersion heater element, tripped RCD, faulty cylinder thermostat, or failed motorised valve. We diagnose the cause and provide a fixed-price repair.
Hot water only runs lukewarm
Top immersion heater has failed and only the bottom element is working, or the thermostat is set too low. We test both elements and replace the failed one.
Hot water runs out too quickly
Degraded immersion element, thermostat issue, or cylinder sludge reducing capacity. We diagnose and restore full hot water capacity.
Immersion heater tripping electrics
A failed immersion element is shorting and tripping the RCD. We replace the element and restore safe, reliable hot water.
Cylinder thermostat failure
Thermostat not regulating temperature correctly — water too hot or too cold. We replace the thermostat and set it to the correct 60°C.
Motorised valve stuck or failed
Valve not directing hot water to the cylinder, or stuck mid-position. We replace the valve head or full valve body as needed.
Airlock in hot water pipework
Air trapped in the hot water system preventing flow. We clear the airlock and restore normal hot water circulation.
Leaking hot water cylinder
Corrosion or seal failure causing leaks. We assess whether repair or replacement is the right option and provide a clear quote.

Hot Water FAQs — Woking
Why do I have no hot water in Woking?
The most common causes are a failed immersion heater element, a faulty cylinder thermostat, a tripped RCD or blown fuse, a failed motorised valve, or an airlock in the hot water system. We diagnose the cause quickly and provide a fixed-price repair.

Can you fix my hot water the same day in Woking?

My hot water is lukewarm — what's wrong?
