Thermal imaging

Find out where your home is leaking heat

With support from

What is thermal imaging?

Thermal imaging can vividly reveal where your home is leaking heat.    The cameras are sensitive to infra-red and make ‘temperature map’ images .    This can show problems with insulation, draughts, damp and more –  useful in older homes, but also for revealing defects in new-builds. The images are easiest to decipher when it’s at least 10°C warmer inside than out, so this is mainly a winter activity.

Some of the problems shown are easy for householders to fix, like draught-proofing, and some, like faulty insulation, may need professional help. Significant improvements in comfort, energy bills and carbon emissions are often made as a result. More in this 2-page report.

Training & camera loan scheme

Come to a short training session to learn how to use our thermal cameras and interpret their images – then you can borrow a camera for free (donations welcome) to survey your home, those of friends or family and (we hope) others in your neighbourhood. It’s great see weaknesses in insulation, draughts, heating system problems in your home. It give good information and motivation to fix the problems that are revealed.

Thank you for your donations, which were invaluable recently:
On Friday 13th January CCF’s oldest thermal Camera, a Fluke TiR in use since 2010, was run over by a car when the borrower’s bike pannier fell off ! – our first camera loss. The insurance pay-out didn’t fully cover the cost of a modern replacement, but thanks to your support we could quickly buy a second Flir C5 and get it on-loan as the new Camera 1 within 2 weeks.

We’d like to loan more cameras to meet the welcome, unprecedented demand. Any support for this is very welcome.
