How the method contributes
A thermal image is a map of surface temperatures. The useful part is its relationship with the heating system, the construction and other findings. An engineer considers recent heating use, insulation and environmental conditions before treating a pattern as evidence. Further checks help establish whether a pipe leak is involved.
Where it can be useful
- Water-based underfloor heating
- Concealed heating pipework
- Comparing affected walls and floors
Its practical limitations
Part of an investigation, not a guess
The engineer chooses the methods that can usefully test a possibility. Results are compared with the property layout and symptoms before access is proposed. See the full investigation and repair process.

When this method may be part of your visit
Tell us the symptoms, previous findings and any restrictions on water isolation. The engineer considers this method alongside the system layout and other available evidence. A test result must be interpreted before choosing an opening or repair.
