Flue Tiles and Fire

Chimney flue tiles are not made to withstand sudden increases in heat. A chimney fire will definitely crack a tile, but watch what happens when even a small fire occurs in a brand new clay tile.

Great demonstration but with poured concrete surrounding the tile it would be protected as the heat would sink through the tile into the surrounding concrete. Even better line the flue with steel pipe

Interesting demonstration! Thanks. I would like to add, the method of how you burn and the design of the stove also can mitigate any creosote problems. When burned properly, a stove designed to burn hot and clean (masonry heater) Including burning ALL the fuel, even the smoke, leaves little remaining in the flue gasses to condense on the relatively cooler flue tiles. Thereby reducing or even eliminating the risk entirely. That is why shutting down an old school stove to smolder all night is the worst practice because it produces the most smoke and the coolest temperatures for all of that to condense on the flue tiles. A stove design with an insulated firebox keeps the fire hot to burn clean. Extract the heat from the fluegases downstream of the fire to heat your home. The now clean and hot fluegases can be routed through a heat exchanger such as a masonry bench to store the energy for slow emission into your dwelling over time.

Good video, crazy because my clay flu tile that's at the very top sticking out of the crown had two cracks and I could see the residue on the outside from seeping through. Old 1976 home, I just replaced the top flu tile since I was pouring a new concrete crown and will be installing a stainless liner for my wood insert.

I’ve always used lots of kindling to get my stove up to temperature as quickly as possible. I’ll sometimes get my single wall flue pipe from 60 to 400 degrees in 5 minutes which now makes me wonder if the tiles outside in the chimney have been heated too quickly. Will find out after the next inspection I guess.

Great information. Thanks.

good reaSon never to use a chimney service

We're did you you go to school Terra catta tile flue pipes are the most safest when they are are in a chimney they repell creosote and handle the heat better than any steel or stainless steel flue pipe and last a lot longer

[@brucedeleskey8540]

Good test good info thanks

[@beaumontmichaels3575]

I bet he installs ALOT of stainless steel inserts!

[@MrSprintcat]

How about an insulated liner how would that work out? Thanks for the video

[@richardkenworthy9312]

Can that be repaired,and if so is it a big process. And is it a expense fix?

[@mr.redneck2715]

When the chimney explodes does it level the house?

[@alexlindekugel8727]

i can only evor get chreasolt to make a light powdery build up get alot of it. but not the thick tar type

[@3172bees]

Very informative. So if you find cracked ones in the middle of the chimney what do you do? Are they removable?

[@brucedeleskey8540]

Have UT cleaned and put in a stainless steel lining in and its done
