| Our Liner Safety Rating
Guide
#1- BEST: HomeSaver Brand Stainless Steel Liner with a direct connection to the appliance. This is the absolute safest way to connect a wood stove to a liner. It is also easier to clean, so you will save on chimney cleaning costs since the stove does not need to be removed for cleaning. Less creosote will accumulate, too. Lifetime warranty. #2- BEST: Guardian Poured liner system. This is a ceramic replacement liner for tile, however it is tested to U.L. 1777, and is the most durable liner we have found. We remove existing tiles, then insert an inflatable bladder and pour the mix around the bladder. We return the next day to remove the bladder, and a round ceramic flue is left. Note: can't be poured in very cold weather. Lifetime warranty. Click HERE for more information on this liner. #3- GOOD: Custom-made Stainless Steel Liner with installation to top of smoke chamber. We will probably also parge your smoke chamber. We only use this application when it is impossible to reline with #1 above, or if the homeowner might remove the stove later. 10-year warranty. #4- NO GOOD: Tile. We do not recommend installing a wood stove or insert with connection to an existing tile liner. Tile liners are sized for fireplaces and are TOO LARGE for wood stoves, which usually require a 6" - 8" pipe. The larger tile liner will not draft properly and creosote will accumulate on the flue walls. 90% of the relining we do is due to a chimney fire caused by this application. Don't Do It! No manufacturer guarantees tile liners.
#1a- Best: Guardian Poured liner system. This is a ceramic replacement liner for tile, however it is tested to U.L. 1777, and is the most durable liner we have found. We remove existing tiles, then insert an inflatable bladder and pour the mix around the bladder. We return the next day to remove the bladder, and a round ceramic flue is left. Note: can't be poured in very cold weather. Lifetime warranty. Click HERE for more information on this liner. Note: a direct connection must be made to this liner from the stove take-off. #1b- Very Good: Custom Steel. Accumulates less creosote and withstands higher temperatures than tile. 10-year limited warranty. Click HERE for more information on this liner. Note: a direct connection must be made to this liner from the stove take-off. #2- OK: Tile. This is what builders install as a liner when the fireplace is built originally because it is cheaper than steel, and currently is still acceptable to code. However, tile cracks under extreme heat (chimney fire), which will make it unsafe to use. The NFPA 211 Standards and local codes usually always require that the liner be replaced when it is cracked. Another problem with tile is that there are mortar joints every two feet, and these deteriorate over time. However, if the homeowner is diligent about getting an annual evaluation by a qualified chimney sweep, installs a chimney cover to keep rain out of the flue, and uses the fireplace PROPERLY, this method should be ok. No Warranty.
#1 - Best: Guardian Poured liner system. See above for more info. Note: can't be poured in very cold weather. Lifetime warranty. #2 - Good: Ventinox or HomeSaver brand Stainless steel liner system. These insulated sturdy steel U.L. listed liners are very good, and have lifetime warranties. #3 - Good: Flexiliner Aluminum liner system. We install a lot of the Flexiliner gas flue liners. They are less expensive than steel, but the installer must be careful not to rip them during installation. Lifetime warranty. #4 - Ok - Tile. Utility flues serving gas furnaces, boilers, and hot water heaters always produce gasses that contain water, which condense on the flue walls. Over time, the corrosive effects of the flue gasses erode tile liner joints and deteriorate the flue tiles. For these reasons, this method is not as good as the other options above and will eventually have problems. No manufacturer guarantees tile liners.
#1 - Best: Class A type stainless steel chimney is used when a stove needs a chimney to vent through the roof. Double wall stainless steel, 24 guage inner wall, 28 gauge outer wall, 1-inch thick insulation between the steel walls. 25-year warranty. Tested to 2100°. Note: ALL of the above methods require an annual inspection by a Certified Chimney Sweep, and cleaning as necessary. All liners accumulate creosote! Warranty applies only if annual inspection is completed by us or another Certified Chimney Sweep. |
