Central Heating Leak Detection

The experts we send to investigate hidden, or hard-to-find leaks in a central heating system are all Gas Safe registered. They have years of experience working on central heating system installs, repairs and servicing.

This means that as soon as a central heating leak is found, they can begin the repair work straightaway. They’re qualified to work on any part of a central heating system; boilers, hot water cylinders, radiators, pipework and underfloor water-fed systems.

In addition to central heating leak detection and repairs, we provide a full reinstatement service too. All the information needed for a successful insurance claim is provided in a detailed investigation report.

Our service is available 24/7 and we don’t charge extra for an emergency attendance, when we aim to be on-site within an hour.

WATCH: Finding leaks in central heating systems

This video shows some of the non-invasive techniques used for finding a leak in a central heating systems.

Every investigation is different. Our leak detection experts follow a methodical “trace and access” approach. They decide on the tests to use based on the evidence available to them and the results they get.

Leaks In Central Heating Systems

Central heating boiler losing pressure

A water fed central heating system is sealed. It should maintain pressure if there are no issues. However, pressure within the system will increase and decrease slightly as it heats up and cools down again. If the system pressure drops regularly and needs to be topped up with water, this is a clear sign of a problem.

If a boiler is regularly losing pressure, a leak in the central heating system shouldn’t be assumed automatically. A Gas Safe registered engineer can first check for faults, such as a damaged expansion vessel, or pressure release valve. Both of these issues can result in the loss of pressure.

Checking for exposed water leaks

If boiler checks don’t reveal a problem, simple checks for leaks in the exposed parts of a central heating system are the first stage of the investigation process. Tiny amounts of water may be escaping from pinhole leaks in radiator panels, corroded pipes or damaged valves and seals.

The “trace and access” investigation to find a central heating system leak will then be carried out. A series of non-invasive prevent floors from being lifted to expose pipework. Once the position of a leak is suspected to within a few centimetres, it’s exposed for visual confirmation and repair.

Non-invasive detection methods

The majority of tests we carry out are completely non-invasive. The location of a leak can usually be pinpointed to within a few centimetres without needing to expose central heating pipes.

Commonly, there are no visible signs of water damage when we investigate central heating leaks. This means two specific tests are vital to an investigation.

Thermal Imaging

Cameras are used to highlight where hot water pipes are located behind/under floors and walls. Temperature gradients between hot water pipes and the space around them are clearly visible.

Sometimes, if a leak is large enough, the hot water pooling beneath a leak will be revealed on the camera. Cool areas detected on the camera can also be an indication of a water leak.

Tracer Gas

The central heating system will need to be drained and filled with a harmless, odourless gas. A sensitive probe is used to detect the gas as it escapes from a leak in the system.The gas is lighter than air and is able to penetrate most floor coverings, including wood, tiles, laminate and carpet. It can even penetrate concrete floors. The detector alerts to where the gas is escaping.

Acoustic Test

When water that’s under pressure escapes from a pipe, it causes tiny vibrations. Our central heating leak detection experts are equipped with highly sensitive acoustic tests that amplify these vibrations into sound. The position of a leak can be pinpointed by assessing changes in sound along the pipe.

Insurance companies usually insist on the approach we take in finding a leak when they’re processing a claim. Every investigation carried out by our experts comes with a detailed report. This can be used to support an “escape of water” insurance claim.

Some of our accreditations

We're fully trade accredited. Aspect is registered with Gas Safe and the National Association of Drainage Contractors (NADC). All our leak investigation experts are vetted and trade accredited. In addition, the Aspect Guarantee covers our tradespeople's workmanship for up to 12 months.

When you book and Aspect leak detection expert you can count on getting the professional expertise you're looking for.

Insurance claim reinstatement

When a central heating system leak has been detected, exposed and repaired, reinstatement work is usually needed to restore things back to how they were. Reinstatement work is usually covered on an insurance policy, but check your policy or ask your insurer.

Our trade experts can provide a full scope of work and fixed price estimate for damage reinstatement. We’ll return the damaged area to its original condition.

We’re always happy to help answer any questions your insurance provider might have. This could relate to any part of the investigation, repair or refurbishment work.
