Chimney Liner Warranties

What is in a chimney liner and what should a consumer look for when shopping for a chimney liner online? Well as you can see from the above chart, the majority of chimney liner brands have a “Chimney Sweep Install Only” warranty. This means by reading the fine print of these warranties reveals that these chimney liner companies advertise that they have a lifetime warranty, but in reality the only way the homeowner can benefit from that lifetime warranty is if a chimney sweep installs the liner for the homeowner. If a homeowner uses this chimney liner and does it themselves, the lifetime warranty would become void.

The only chimney liner brand that we found with a lifetime warranty for the do it yourself homeowner was the Flex King brands. They offer a lifetime chimney liner warranty that covers all chimney liner parts for the life of the liner, which is usually 5+ years and is transferable to the next homeowner. So whether a homeowner or a chimney sweep installs the chimney liner, the Flex King lifetime warranty covers you and will save you money from having a professional install one of the other flue liners.

What is 316Ti Mean and Why Should I Care About the Thickness of My Chimney Liner?

316Ti is the stainless steel quality of the alloy used for making a chimney liner and the “Ti” means titanium. As you can see from the graph, 316Ti is the standard alloy used to manufacture chimney and flue liners. Now what makes them different is the thickness of the liner.

As you can see the majority of the chimney liner manufacturers produce chimney flue liners ranging from 0.005-0.006 inches in thickness. The only chimney liner we found that gives you qualities of a rigid liner, but remains flexible was the Flex King Pro. When tested, the Flex King Pro chimney liner created 20% more draft and also had the only smooth wall interior. Having a smooth wall interior compared to rippled or corrugated interior means that there will be less creosote buildup and much easier cleaning. Also with the added thickness, Flex King Pro can withstand more heat over a longer period of time. Thus having a longer life span then the other chimney liners we tested.

What is the Chimney Liner Purchase Source?

The final criteria that we looked at was the purchase source. The reason this is important to the consumer is that when buying from a distributor rather then direct from the factory, you are not getting the lowest price possible. Buying from distributors means there are usually extra costs that are being passed on to the consumer. As you can see from the chart, the Flex King brands are manufactured and sold direct from the factory. Looking more closely, the Flex King chimney liner brands have the lowest overall prices compared to the other chimney flue liners. Also by dealing direct with the factory all of your questions and concerns about the product can be answered by the source rather then a third party or distributor.
