Assessing cold/hot spots in your house December 23, 2009

Last winter I was frustrated by what felt like pockets of cold air in various parts of my house.  Sometimes it was easy to confirm (like if there was a breeze), other times it might have been my mind going crazy.   This year I ordered the kintrex infrared thermometer instead of going to the psychologist and boy has it made a difference.

Use Case #1:  Take the closet in an older part of our house where the exterior wall is brick. The closet is always cold, some of which i attributed to being cut-off from heat vents.  After shooting the wall and seeing that its temperature was 15 degrees colder than an insulated wall in a different closet I immediately picked up some rigid insulation.  With the rigid installed over the brick closet wall the temp was 10 degrees warmer.

Use Case #2: a long, long duct run in my basement supplies heat to our great room.  Shooting the duct near the furnace showed the metal was around 90 degrees,  however 35 feet down the run toward the great room the duct metal was only 72 degrees.   So clearly i’m able to quantify the heat loss from the long run in the colder basement and thus this is motivating me to insulate the duct.   I’ll post the update after i do the project, but the point is that i would never have known the heat loss was so great without this device.  (see pic below)

kintrex If you’re paranoid about energy efficiency in your house and need to validate your paranoia for yourself or a loved one this is the tool. Runs about $50.
