Thermography has become a widely used diagnostic tool in the heating sector, offering significant time and cost savings for engineers. Testo thermal imagers are particularly valuable for detecting issues like locating heating pipes and identifying leaks, especially when pipes are hidden under tiled or concrete floors. By using a thermal imager, engineers can quickly trace the path of pipework, reducing the inspection area and minimizing property damage. For example, thermal images can reveal heat patterns from heating pipes and identify irregular hot spots, which often signal leaks. This targeted approach allows heating engineers to address issues efficiently, expanding their service offerings with minimal disruption to customers' properties.
