An electrical thermal imaging survey is a non-evasive and non-destructive procedure using infrared technology. The cameras are designed to perform a wide range of tasks including electrical inspections, detecting thermal patterns and identifying areas of heat loss. Here at ETR, we offer thermal imaging surveys for another in the UK or Ireland. Keep reading for what it is, how it works and the benefits. 

What are thermal imaging cameras?  

Did you know that thermal radiation was discovered by Sir William Herschel in 1800? His son Sir John Herschel went on to develop the revolutionary first thermal camera using carbon suspension in alcohol. Today, thermal imaging cameras are thermographic cameras that are used to render infrared radiation as visible light, allowing you to find differences in wave speeds and temperature. They can detect faults such as loose connections, overloaded circuits and transformer cooling faults and induced currents. 

How do thermal imaging surveys work?

Thermal imaging surveys are quick and easy methods to detect and rectify issues with electrical and mechanical equipment or moisture leaks and insulation deficiencies in your home or business. For example, thermal imaging of a wall could show dark spots, which are colder areas and indicate heat being transmitted outside. 

Benefits of Thermal Imaging Surveys

  1. With thermal imaging surveys, issues with poor connections can be identified. Often these would be missed by electrical testing and inspection. 
  2. There is no disruption to your business when you choose to have a thermal imaging survey carried out. Our team here at ETR will have it done quickly and safely. 
  3. The surveys give excellent insight into the operational effectiveness of equipment. This will enable the identification of opportunities to make energy savings and increase the operational life cycle of equipment. 
  4. You will notice a reduction in the cost of breakdowns, as a thermal imaging survey will identify faults before a breakdown happens. It is cheaper to pay for repairs rather than breakdowns!


Thermal imaging surveys are highly recommended and a commendable investment for any property owner to make. The implications of the results, in terms of finance, environmental integrity and safety, can be life changing! If you are keen to organise a thermal imaging survey, get in touch with us today. We will be happy to help.
