Winter is here and although yesterday was a pretty nice day (where I live) the temperature has gone back down today and the heater goes on as with many other homes. The thing is though a lot of us are using more heat then necessary due to either old windows, old heating systems or simply because of thermal leaks. Well Black & Decker has made a Thermal Leak Detector to fix those problems.

What this device does is by simply pointing and clicking at a certain area, around a window for example, the device will read the temperature and will show changes as small as 1 degree. If the temperature change is significantly different from that of your home then that is a place you need to patch up because the air is leaking through.

This device is only $40 and Black & Deckers states that it can save you up to 20 percent in energy costs by pointing out all the thermal leaks in your house. This device simply finds the leaks for you though, it’s up to you to patch them up. If you are interested you can buy one of these are your local hardware store starting at the begging of next year.
