It measures surface temperature patterns
A thermal camera does not provide an X-ray view of a wall. It displays differences in surface temperature that may be influenced by pipework, moisture, heating and the surrounding environment. A striking colour patch is a clue, not a diagnosis.
The same pattern can have different causes
Insulation changes, draughts, reflections and normal heating routes may all affect an image. A cold patch does not automatically mean water is present, and a warm route may simply be a functioning hot pipe. The construction and operating conditions matter.
Use another test to answer the next question
Moisture mapping can help assess whether an area is unusually wet, and suitable system tests can investigate whether a circuit is losing water. The engineer uses complementary evidence to decide whether a plumbing escape is supported.
Useful reporting explains the image
If a thermal image forms part of the findings, its relevance should be explained in plain language. A homeowner or insurer needs to know what the image supports and what it cannot establish. The report should connect the observation to the investigation and access decisions.
