Why use a Chimney Balloon?

Why Look at the Chimney?
Homeowners spend millions each year caulking, replacing windows & doors, and weatherstripping to make their home more energy efficient. However, one of the biggest culprits of energy loss is not so easy to see, it is the fireplace damper. The damper is the metal flap in your chimney that acts as a fireplace plug when you are not using it. That damper gets warped and degrades over time. Often you cant tell it is not sealing because you cant look at it close, but you can feel the cold air. What you need is a more effective inflatable chimney stopper to eliminate the cold fireplace draft.

The GOOD functions of Chimneys: Chimneys act as a funnel and pump to take smoke and dangerous gasses away. This is good when there is a fire.

The BAD functions of Chimneys: Chimneys work hard even when there is no fire. So they are the easiest escape route for the warm air in your house. The symptom of heat escaping your chimney is cold air in your fireplace or powerful drafts from very small gaps in your windows or doors.

How Do Cold Drafts Happen In Your Home?

Cold air rushes in through the gaps in the floors, doors, windows, outlets, and down the chimney. We seal floors, replace and calk windows, plug outlets, but often neglect to take a closer look at the hole in the roof, the chimney. Cold air can't get in unless it is going out at the same speed. Often times your fireplace chimney is the culprit allowing the escape of warm air for the other drafts to rush in.

How Can You Stop Your Chimney From Releasing Air While Not In Use?

Is it hard to get a chimney to not do what it is designed to do? Here are a few unsuccessful methods.

  • Use the damper. This works great while the metal flapper is new, but over time it leaks because of repeated heating and cooling and warping. Some fireplaces have no damper or have cheap dampers that are not very functional when they are new.
  • Block your fireplace with bricks or boards: Then it looks ugly and you can't use your fire when you feel like it. and the cold air still comes through the cracks unless you mortar the bricks or boards. Also, the chimney will get damp because the bricks aren't breathing.
  • Stuff newspaper or fiberglass into the chimney throat: Newspaper is a bad insulator, flammable, and will blow around and move. Fiberglass is itchy and messy and leaves residue in the chimney.
  • Install a permanent seal cap on the top of the chimney: Do-it-yourself kits can be flimsy and professional grade caps are expensive. Furthermore, if your cap is permanent forget lighting pleasant fires again.
  • Install a chimney top damper: These work great to keep out air and debris. Unfortunatley hot air still rises into your chimney only to cool again and sink back down the chimney. This convection process can feel like a constant cool draft coming down the chimney. This is why it is important to seal your chimney as close to the hearth as you can to prevent this problem.
  • Inflate an ordinary balloon and stick it in the chimney:
    If you can manage to get it in without bursting, it will shrivel up within a day as ordinary balloons do.
