Our Megaflo cylinder was making strange noises and the hot water kept running out. The engineer replaced the immersion heater and descaled the system. Now we have plenty of hot water again and it's much quieter too!

Common hot water cylinder issues include faulty immersion heaters, thermostat failures, leaking cylinders, pressure relief valve problems, and expansion vessel faults. Our engineers can diagnose and fix these issues efficiently.
This could be due to a faulty immersion heater, thermostat issues, limescale build-up reducing cylinder capacity, or problems with the boiler's ability to heat the cylinder. Our engineers will identify the specific cause and recommend the appropriate solution.
Minor leaks from connections or valves can often be repaired. However, if the cylinder itself is leaking from the main body, replacement is usually necessary as repairs are rarely effective long-term. We'll provide honest advice based on the specific situation.
Most hot water cylinder repairs can be completed within 1-2 hours once we've diagnosed the issue. Replacing components like immersion heaters or thermostats is relatively straightforward. Full cylinder replacements typically take 4-6 hours.
This depends on the cylinder's age, condition, and the nature of the fault. For cylinders under 10 years old, repairs are usually worthwhile. For older cylinders with significant issues, replacement might offer better value, especially as newer models provide better insulation and efficiency.
