thermal leak detector

The gadget makers over at Black and Decker have just released a very cool new machine called a Thermal Leak Detector, which uses infrared sensors to pinpoint the source of cold spots in the house. It works by shining a light onto the wall around doors and windows. As you move the light, the device will sense the temperature of the surface it’s pointed at. As soon as it hits a cold spot, the light turns from red to blue, indicating where you might have to do some insulation repair.
Black and Decker says this handy device will help your family save 20% of your heating or cooling energy costs, which is pretty important these days, with families becoming more cost conscious and more energy efficient!
