Older homes have a tendency to have all kinds of drafty areas and sealing them up tends to be a nightmare. However, if you want to bring down your heating bill it becomes necessary to take care of the problem. Installing new windows can help, but finding the specific problem areas would make things a lot easier. Well this Black & Decker Thermal Leak Detector can help you with exactly that.
To use it, point it at a wall for a reference temperature, then go to the areas you think might be letting in the cold air. The gadget will then turn either red or blue depending on if it has found a cold or a hot spot. I’m sure you can guess which color indicates which. It only changes color when it detects a temperature change of 1, 5, or 10 degrees Fahrenheit (it can be switched to Celsius). It will also display the temperature on the LCD screen. To go with the detector is a guide on how to insulate and seal up your home. You will be able to purchase it on Black & Decker’s site for $39.99. As of now though, it’s still classified as coming soon, so no word on when it will actually be released.
