Short answer: A thermal imaging camera can help you locate cold spots in a house by showing differences across walls, windows, doors, floors, ceiling edges and accessible pipe routes. The useful result is a better inspection question, with the picture saved beside your notes. This camera shows a white-hot image, saves BMP files to 8 GB of built-in storage or an SD card, and runs on a rechargeable lithium battery. Compare surfaces and record the conditions before you decide whether a building professional is needed.
Read a cold spot as a starting point
A cold spot may be associated with an external corner, a window reveal, a door threshold, a floor edge, a ceiling junction or a room with different heating. The camera shows the surface pattern under the conditions at that moment. Save the wider scene and the close area, and write down the heating, the weather and what you plan to check next.
The white-hot palette can make a broad warm-versus-cool comparison easier to view. Use it consistently, save the wider scene as well as the close area and write down what you were investigating. That simple discipline keeps the image tied to the house rather than detached from it.
| Cold-spot location | Useful comparison | Limit |
|---|---|---|
| Window reveal | Compare frame, sill and nearby wall | A colder edge still needs a closer look |
| External corner | Compare with a central wall and another room | Pair the picture with a moisture check |
| Floor or skirting line | Compare along the same wall | A cold patch is a place to inspect |
| Ceiling or loft edge | Compare adjoining ceiling areas | Keep the image with your notes |
Prepare the house before scanning
Choose a room where the cold spot is noticeable and note recent heating, sunlight, ventilation and furniture placement. Avoid turning an unusual one-off condition into a permanent conclusion. A scan after direct sun or immediately after a heater has changed the surface can be difficult to compare with another day.
A rechargeable lithium battery and the handheld body suit moving between rooms. Charge it before you start, because a runtime figure is not part of the published details. The SD card slot, 8 GB of built-in storage and BMP saving are there when you want to keep a sequence of images for later review.
Make the cold-spot check repeatable
A small log is more useful than a large pile of unexplained files. Use the same order in each room and keep the room name in the file notes. If a pattern repeats, it becomes a better reason to investigate; if it disappears when the conditions change, that is also useful information.
- Record the room, surface, date, heating state and relevant weather or sunlight.
- Capture a wide image of the wall or opening before moving closer to the cold spot.
- Repeat the same view in a comparison room or on an adjoining surface.
- Use the pattern to choose a seal check, ventilation review, insulation inspection or professional assessment.
Do not over-read the colour
GOV.UK guidance treats damp and mould as conditions that need causes and remedies addressed. A thermal image may support the conversation, but it does not prove damp, mould source, structural failure or a hidden leak. If there is persistent mould, visible water damage or a dispute about a property condition, use the appropriate building method and competent advice.
At £232.85 with VAT included, it can be a reasonable camera for repeated visual checks around a home or a small maintenance round. The published details cover the white-hot image, BMP saving, the SD card slot, 8 GB of built-in storage, IP55 and a 1 m drop test. Keep the pictures with your notes when you hand the question to the next inspection.
