Local Central Heating System Leak Detection & Repair Specialists in the UK

UK Central Heating Leak Detection

In order to evenly distribute heat throughout all areas of your house, the central heating system relies on pressurised water. However, a challenge arises when this pressure decreases significantly, causing the boiler to automatically shut down. Consequently, both heat and hot water become unavailable.

If you're frequently having to refill your boiler to maintain the proper pressure for the central heating system, it's likely that there is a leak that needs attention.

What Can Cause A Central Heating System Leak in the UK?


A central heating system, while intricate, can be simplified by recognising its core components that have the potential to develop leaks:

  • Radiators: Over time, leaks might arise in the valves, connections or the radiators themselves.
  • Boiler: Leaks can manifest in the heat exchanger or other internal sections of the boiler, leading to water seepage.
  • Pipework: The pipes responsible for conveying hot water from the boiler to radiators or other heating elements can develop leaks due to corrosion, damage or flawed connections.
  • Expansion Vessel: Integral for absorbing water expansion as it heats, a faulty expansion vessel or a burst bladder within it can result in water leakage.
  • Pressure Relief Valve: This safety component discharges excess boiler pressure. In some instances this valve can malfunction, causing water leakage.
  • Pump: Responsible for circulating water through the heating system, a damaged pump housing or seals can bring about water leakage.
  • Header Tank: Certain older central heating systems utilise a header tank to supply water. If this tank has cracks or faulty connections, it can lead to water leakage.

At SOS Leak Detection Ltd, we possess the expertise to address these potential leaks, ensuring the integrity of your central heating system.


Does Your Heating System Lose Pressure? Are You Experiencing Boiler Breakdowns in the UK?

Within enclosed systems like heating circuits and heating setups minuscule and unseen leaks, often referred to as Micro Leaks, can lead to a gradual yet consistent drop in system pressure without any apparent explanation. These Micro Leaks tend to be more frequent in heating circuits and hot water pipes.

Due to the higher temperature of the water, it evaporates rapidly, leaving minimal or no evidence behind. The continual pressure loss ultimately culminates in a boiler breakdown. At SOS Leak Detection Ltd, we excel in the identification, assessment and effective repair of these leaks. Our expertise ensures that your heating system remains dependable precisely when you require it the most.
