Thermal imaging camera shows where heat leaks from home


CONCORD- The bitter cold really hits you when you're outside, but once you get inside how can you be sure all of that heat you're paying for is actually staying inside your home.

NH1 News rented a thermal imaging camera and when we pointed it at the front door of a Concord home, we could see areas in blue which are the coldest spots.

Well those might as well be green because that's your money getting thrown out the window. The area where the door meets the floor is one of the coldest spots we found in this particular home, but it might be one of the easiest fixes for you to do yourself.

It can be as simple as putting a towel down. The camera went a dark blue reading which shows the coldest air, to no blue, the towel blocks the leak.

But it's only temporary.

An experiment with an open refrigerator shows how accurate the camera is and how well some glass can act as insulation.

According to Alec O'Meara of Unitil, older windows like the ones in the Concord home we tested in are typically problem areas for losing heat.

"So you really want to look around the edges of windows make sure you don't have any gaps that are letting your heat out. Because if you lose heat through the window, your who house gets cold," O'Meara said.

Newer windows like the ones at our NH1 studios keep the cold out.

"That's where the glass is meeting the house. So this here is where you would lose heat. Not through the physical glass, the center of the glass no. It's the edges it's the seams," O'Meara said.

O'Meara says there's a number of fixes you can do yourself. If you make the investment, you could save hundreds of dollars a year.

"But it also is a quality of life issue. If your home has a lot of drafts it's always cold, your house is just cooler and you're just not as comfortable. So not only could you save a lot of money but you can also just be more comfortable and enjoy the winter months a little bit more," O'Meara said.

You can rent a thermal imaging camera at Home Depot and do this all yourself or you can contact Unitil and they'll check your home for free and give you suggestions on the best and most affordable ways to keep your home warm this winter.
