Central Heating Leak Detection in Devon

If your boiler pressure keeps dropping or you are forever topping it up, the most likely cause is a hidden leak somewhere in your heating system. We pinpoint the exact spot, in pipework, radiators, valves or the boiler itself, before anything is lifted or opened up.

What Is Central Heating Leak Detection?

A sealed central heating system should hold its pressure for months on end. When you find yourself reaching for the filling loop every few days, water is escaping somewhere, and that water has to be going into the fabric of your home. Central heating leak detection is the process of locating that escape precisely, so the right joint, valve or section of pipe can be repaired and nothing else is disturbed.

Heating leaks are often slow and easy to miss. The pipe runs are hidden beneath floors, buried in walls or sitting under screed, so the only clue is the pressure gauge creeping down or a faint patch of damp. Left alone, a small weep can rot floorboards, lift tiles and quietly raise your energy bills as the boiler works harder to reheat lost water. We use non-destructive equipment to confirm exactly where the problem lies, across Devon and lightly into neighbouring Cornwall, so you are not paying to chase a guess.

Signs Your Heating System Is Leaking

How We Find Central Heating Leaks

Thermal Imaging

Heating water is warm, so a leak leaves a heat signature. Thermal cameras map the warm pipe runs beneath floors and walls and reveal where hot water is escaping, often pinpointing the source without lifting a single board.

Pressure Testing

By isolating sections of the system and applying a controlled pressure, we can confirm whether a circuit is losing water and narrow the leak down to a specific zone. It is a reliable way to prove a leak and rule out healthy pipework.

Acoustic Detection

Water escaping under pressure makes a distinctive sound. Using sensitive acoustic equipment, we listen along pipe runs to trace that noise back to its source, ideal for confirming a leak hidden beneath solid floors and screed.

Central Heating Leak Detection FAQs

The most common cause is a leak somewhere in the sealed heating circuit. As water escapes from a pipe, joint, radiator valve or the boiler, the system loses pressure and you find yourself topping it up repeatedly. Pinpointing the leak lets you fix the actual fault rather than masking it.

In most cases, yes. We use thermal imaging, acoustic listening and pressure testing to locate the leak non-destructively before anything is opened up. This means any repair work is targeted to the exact spot, keeping disruption to your floors and decor to a minimum.

Sealant additives can be a short-term patch, but they often only mask a small weep and can clog valves and the boiler over time. Locating and repairing the actual leak is the lasting fix, it protects your home from ongoing water damage and avoids repeat top-ups.

We aim to offer same-week appointments often available. If your pressure is dropping fast or you can see active water damage, let us know when you call and we will do our best to prioritise your visit and get the leak traced promptly.

Our findings are documented in clear, insurance-approved reports that set out where the leak is and how it was located. Many home insurance policies cover the cost of tracing and accessing a leak, so a professional report helps support your claim.
