What the method does
A thermal camera makes surface temperature differences visible. It can help an engineer interpret a heating route or an unusual pattern, but the image is a clue that needs context. Recent heating use, sunlight, insulation and surface materials can all influence what appears.
Temperature is evidence, not a view through the floor
Useful observations are compared with the suspected pipe route, moisture readings and system checks. A warm area may reflect normal heat transfer rather than a defect. A cold area may be influenced by evaporation, a draught or the building fabric. The value lies in joining these observations to the rest of the investigation.
Where it may be useful
- Water-based underfloor heating loops
- Concealed hot-water and heating routes
- Comparing affected and unaffected surfaces
What it cannot establish on its own
A thermal camera does not see through concrete or prove a leak on its own. Some faults create little useful surface contrast.
Before the visit
Tell us when the heating was last used. Follow any system-specific advice given before the appointment, rather than changing temperatures simply to create an image.
An investigation, not an equipment checklist
The most useful method is the one that answers the next question about your plumbing. A visit may combine observations and tests, or find that another specialist is needed. We explain the findings and proposed access before the agreed repair. Our package is defined by its scope, not by using every instrument.
