Negative Air Pressure

When you have a fire in the fireplace, does the smoke enter the rest of your home?
Most of the time, problems with the draft are to blame for a smokey fireplace. It is essential to have a fundamental understanding of the notion of chimney draft before digging into the myriad of different forms of draft problems.

The smoke is drawn upward and out of the chimney thanks to the negative pressure that exists inside the chimney, which is referred to as “draft.” A draft is formed when the air moving through a space has a slighter greater negative pressure than the air around it. This disparity in negativity is denoted by a very small negative number that is expressed in terms of units that are referred to as “water columns.” When operating at peak efficiency, the chimney allows the hot air to escape upwards and out of the top. You presumably learnt in elementary school that hot air rises and cold air descends; nevertheless, this theory does not always hold true and can be broken in certain situations.

When there is really somewhat less air located inside of the residence than there is outside of it, negative air pressure might develop. This results in the air movement actually traveling down the chimney rather than up the chimney. This is something that should be kept in mind, particularly during the warmer summer months. Thankfully, there are a few different approaches that may be taken to solve this issue.

In the short term, you can try opening a window in order to better balance the air pressure. Newer homes sometimes have the issue of being too efficient in terms of keeping the outside air out, which results in the air traveling down the chimney. If you want a solution that will last for a longer period of time, make sure that the fire damper is closed whenever the fireplace is not being used. However, even little damage or improper installation can still result in issues with negative pressure, so be careful. A glass fire screen placed in front of the fireplace can act as an additional barrier, preventing the buildup of even more negative air pressure. Last but not least, ventilation for fresh air from the outside can be added to other combustion appliances such as stoves.

Put an end to those revolting smells coming from the chimney.
The accumulation of creosote and leaves are two of the most prominent factors that contribute to the stench coming from a chimney. Animals are known to leave behind a wide variety of waste products, including dead insects and other gruesome remains that have a putrid odor.

Moisture may make all of these problems much worse, as well as generate new ones. For example, if your home has a negative air pressure, then all of this scent will be pushed directly into your home. The principal contributors to these odors come from a variety of different places, but the problem can often be solved by ensuring that the chimney is regularly cleaned out and maintained as required.

In support of knowing these essential information, it is for the best that you also have a company you can count on to help you with Chimney Cleaning Rescue and repairing like Local Chimney Sweep Cleaning.
