While many of the more traditional approaches to improving energy efficiency remain effective, some are choosing to utilise thermal imaging technology to gain a better understanding of their home's propensity to lose heat.
Thermal imaging cameras allow for users to inspect their home, highlighting hotspots and coldspots around the property. A hotspot indicates areas where heat is being retained, typically highlighted by brighter orange and red areas within a thermal image, while cooler coldspots are often outlined by darker blue, black and purple areas, suggesting heat may be escaping from these places.
Performing a thermographic inspection of the home allows occupants to take informed steps towards improving their energy efficiency by addressing the presence of coldspots. These areas may be improved by the considering additional insulation solutions, often as simple installing curtains or a draft excluder around windows and doors, or more invasive insulation options, such as those installed within roofs, walls or crawl spaces. Cat flaps and letter boxes may be improved by adding a brush to the entrance to ensure a tight seal, reducing heat loss. In many homes, bare floors can account for as much as 10% of heat loss, meaning that adding a rug can make a significant improvement. Some owners may choose to go further through the installation of air or ground source heat pumps.
