Unless the reason for your chilly laundry room is cold air infiltrating the space through your existing dryer vent, this product won't do a thing for you. All it does is provide a more a more complete closure on the exterior vent termination (while the dryer is not in use) than whatever device you probably already have in place.

BTW, if you go ahead and install this particular device, be sure to check your dryer vent much more frequently for lint build-up and obstruction.

actually, that is the only place the cold air can be coming from. the house is pretty new and is well insulated. I can;t feel any cold air around the window in there either. I just wasn't sure if I was wasting time and money on something that people have tried that was just a gimmick.

i put those on my house. in theory it should work but mine froze up a couple times this winter.had to go up in the attic and bang on the pipe.
by the way you can get them at menards for 11 bucks.

We've had one for at least 20 years. It does provide warmth to the basement, but it's also providing humidity, which may or may not be good in your area. The basement also smells like fabric softener. They can't be used on any gas appliance.

Baymee,

The reference and link is to an outside vent termination. (the one with the ball seal) I think your assuming their bloging about inside heat savers.

OK, I didn't know about that type.
