Why Your Oil or Gas Heating Appliance Needs a High-Performance Chimney Liner

A chimney liner is one of the most important components of your fireplace and chimney system because of its functions. A high-performance chimney liner will protect your home from extremely high temperatures igniting a fire within your woodwork, protect your masonry chimney from the toxic byproducts of combustion, and provide a correctly-sized flue to your heating appliance to improve the draft. Particularly if you have an oil or gas heating appliance, you need a durable stainless steel chimney liner due to the acidic properties of the combustion gases. Many times All Seasons Chimney will see problems with cracks and gaps in older clay tile flue liners when we inspect chimneys of oil and gas heating appliances. These cracks and gaps can be hazardous as they can allow poisonous gases like carbon monoxide to enter your home. We have also seen problems with the flue sizes being too large for these types of appliances. We would like to tell you more about why your oil or gas heating appliance needs a high-performance chimney liner by sharing with you some information from the Chimney Safety Institute of America (CSIA).

Why is the flue size such an issue for oil and gas heating appliances?

The newer oil and gas heating appliances require smaller flue sizes than the older units did. Typically, there will be about a 60% reduction in the flue size. Additionally, these newer appliances have lower flue gas temperatures, and this can add to the problem of the flue being too large for the appliance. Draft can be drastically reduced because the cooler the gases become, the slower they move up the flue. This can cause your oil and gas heating appliance to work ineffectively and to use more fuel to provide sufficient heat. Flue gases remaining inside the flue for too long can also be hazardous as it increases the risk for leaks. Another major problem that can occur with an improperly-sized flue is the condensation of water vapor. The moisture that results can be absorbed into the chimney and transferred through the walls of your home. This can cause your paint and wallpaper to peel. Even worse, the masonry materials of your chimney can be severely damaged during the freeze/thaw cycles of winter, and you can have spalled bricks, eroded mortar joints, and water leaks at the bottom of your chimney.

How can All Seasons Chimney solve this flue sizing problem?

The best way we can solve this issue is to retrofit your chimney with a properly sized and installed UL Listed stainless steel chimney lining system. This will help your draft by keeping the flue gases from expanding and cooling more than they should. Condensation within the venting system will also be reduced with a properly sized high-performance chimney liner. We will guarantee that your liner system is watertight so that any condensation that should form will remain contained within the liner to avoid further damage to the masonry from the freeze/thaw cycles and corrosion from the extremely acidic condensate.
