Hot Water Repair FAQs

Why do I have no hot water but my heating works fine?

This could be due to several issues: a faulty diverter valve in combi boilers, problems with the hot water cylinder in conventional systems, thermostat issues, or pump failures. Our technicians can diagnose the specific cause.

How long does it typically take to fix hot water problems?

Most hot water issues can be diagnosed and repaired within 1-2 hours. However, if parts need to be ordered or if there's a complex underlying issue, it may take longer. We'll always provide a timeframe estimate after diagnosis.

Can you repair my immersion heater?

Yes, we repair and replace immersion heaters in hot water cylinders. Common issues include faulty thermostats, failed heating elements, or wiring problems, all of which we can fix.

Why is my hot water running cold after a few minutes?

This is often caused by a build-up of limescale in your system, a faulty thermostat, problems with the diverter valve, or insufficient hot water storage. We can identify and resolve the specific cause.

Is it worth repairing my hot water cylinder or should I replace it?

This depends on the cylinder's age, condition, and the nature of the problem. We'll provide honest advice on whether repair or replacement offers better value. Generally, cylinders over 10-15 years old with significant issues may be more economical to replace.
