I recently purchased the Black & Decker TLD100 Thermal Leak Detector from after feeling a draft in our new house.  We moved in to our new place about 7 months ago, in the middle of the Spring and it’s always felt perfectly insulated.  The house is brand new and its energy-efficiency was one of the selling points.  It’s solar, septic, well water and uses a natural soy insulation along with thermal windows that all do an amazing job of keeping the joint at the perfect temperature.

A thermal leak detector helps homeowners track down power-draining drafts by using infrared sensors to measure surface temperatures.

Now that we’ve entered the cold of Autumn and we have the fireplace roaring, I’ve started feeling a draft running through the house.  I couldn’t quite tell where it was coming from, so I figured I would use that as justification to buy a new toy…I mean a new tool :) .  After researching several different thermal draft detectors for a few days (I research obsessively before every purchase), I decided to go with the Black & Decker TLD100 that I purchased from Amazon.

During my research, I found a few mixed reviews, but overwhelmingly, the consensus was that the bang for the buck on this thing is amazing…with 4.5 stars on Amazon and more that 200 reviews…other leak detectors can g for $100.00 and more.

Once leaks and losses are narrowed down, then a trip to the hardware store to get some caulk, weather stripping, and limited insulation for hopefully less than one hundred dollars will go a long way to spending less on heating and cooling.”

Two days later, my B&D Thermal Leak Detector arrived and I did what any man would do….I tore the box open, made sure it had a fresh 9 volt battery, bypassed the instructions, and started aiming it at everything in sight…at least for about 2 minutes, then it dies.  I was confused.  I checked the owners manual, went through the trouble shooting, and changed the batteries, but I couldn’t get this fun tool working again.

I reported the defect to Amazon and they had a new one on its way to me before I even hung up the phone.  The Black & Decker TLD100 Thermal Leak Detector arrived the next day and worked flawlessly. A slight inconvenience but no big deal.

Here’s how this thing works.  You set the temperature discrepancy you want it to report on, 1 degree, 5 degrees of 10+ degrees.  You point it at a surface as your reference temperature, usually an interior wall and the TLD100 uses that as your base temperature.  Every surface you scan after that will use that base temperature and tell you if the surface is within range hotter or colder than the reference temperature.

When you point the Black & Decker Thermal Leak Detector at a surface and pull the trigger, it shows one of three colored circles on the surface, green which means that surface temp is within range; red which means that surface temp is hotter than range, or blue which means the surface tem is colder than the acceptable range you selected.

It doesn’t get any easier.

Within five minutes I found the source of my leak at our front door.  I opened our door and low and behold, there was a piece of weather strip missing.  A quick trip to Home Depot, picked up a new strip and all was good again.

Overall, I’m happy with my purchase of the Black & Decker TLD100 Thermal Leak Detector.
