7) Thermal Imaging

Thermal Imaging

Thermal Imaging Cameras detect radiation in the infrared range of the electromagnetic spectrum and produce an image of that radiation called a thermogram. When there is a problem with an underfloor heating system, we use a thermal imaging camera to see which loops are receiving heat.

The most common problem is due to the fact that actuators have been wired to the wrong thermostat. In these circumstances, for example, the dining room stat will call for heat – and the actuator opens and allows warm water into the loop for the sitting room!

Other problems we have discovered when investigating sites on behalf of clients are installations with inadequate pump power, so warm water does not fully circulate around the system. And one case where the builder decided to relocate patio doors, so that our underfloor heating installation looped back underneath a section of an outside patio!

Examples of Thermal Images at different temperatures are illustrated below:
