Fireplace Backdrafting

The neutral pressure plane, often known as the NPP, has a close connection to the stack effect. It takes place in locations where there is no change in pressure between the interior and exterior of the space. Its placement is decided not only by the total volume of air that escapes from the home but also by the area in which this air loss takes place. Because the home is a dynamic system, the position of the NPP shifts according on the temperature and wind speed of the surrounding environment (the drivers of the stack effect).

Fireplace dampers are a sort of backdraft stopper that are used in fireplaces. The same is true for stove dampers that are attached to appliances located in the basement. Even when they are closed, they will let roughly the same amount of air in as when they are open.

There are certain items that will aid your chimney downdraft appliances, such as your furnace or water heater, as well as your fireplace appliances. When it comes to fireplaces, the installation of a chimney damper cap (with sealant applied at the top of the chimney), creates a closure that is rather airtight. When installing these damper caps on vented gas fireplaces, extreme caution is required since there is a risk that they will be forgotten, which will result in the damper being closed while the gas log is burning, which creates a risk of carbon monoxide poisoning.

Consider installing a fireplace fresh air intake system in your basement if you’re seeking for a solution that will work for both backdrafting fireplaces in the basement and gas heating equipment.
In most cases, fresh air intake systems are unobtrusive, passive devices that bring outdoor air inside, where it is most desperately required. Some systems will clean and warm the air before bringing it into your house, while others will just clean the air. During a time of year when we’re trying to keep as much heat as possible, the idea of letting outdoor air into the home may sound appealing. However, it’s important to keep in mind that the house will get this air some other way or another, so why not just control what is already happening naturally?

In addition to bringing the Neutral Pressure Plane down, the use of a fresh air intake system has a number of other advantages. Sometimes the air within is just as harmful and stuffy as the air inside of an inner city industrial district. Intake systems for fresh air make it possible to control how much of this air is brought into your house and into your body. The majority of homeowners will not experience an increase in their power expenditures as a result of the reduction in pollution and humidity, and they will also appreciate leading a healthier lifestyle.

Placement of Windows and Doors Below the Neutral Pressure Plane
Windows in our negative pressure plane follow the same pattern as Example #1 in this respect. The true cause of an air leak is not the gaps and cracks themselves, but rather the pressure that exists in the area where the defect is located. Because lower levels of the home are experiencing lower air pressure (as a result of the stack effect and other sources of indoor air loss), air from the outdoors is leaking inside the home in an effort to relieve the air that is being lost to the same gaps that are located above the neutral pressure plane. If they are not excessive, these particular leaks assist us achieve our goal of lowering the neutral pressure plane and satisfy the requirement that our dwellings have for fresh air. Every single cubic foot of air that enters our basement in any other way except through the fireplace contributes to the efficiency of our backdrafting basement fireplace as well as all of the other venting appliances in our home.

When our chimney sweeps assist homeowners with fireplace backdrafting difficulties, we usually propose weather stripping windows and doors as well as closing gaps above the neutral pressure plane. This is not necessarily the case below the neutral pressure plane.
