Why insulate your stainless steel chimney liner?


Basically you need insulation for safety and performance.  The safety issue is a no brainer.  Keep the extremely high temperatures that can reach 2100 degrees away from your home and prevent a house fire.

The second reason, performance, is a more difficult one to understand for some.  Here is a picture of a cap from a customer who did not use insulation around the stainless steel chimney liner.  The smoke cools down too much and creates creosote.  The screen was almost completely blocked on this rain cap.

Why buy a Chimney Liner now?

First, it can be very dangerous to wait.  The chimney may appear to be in good condition on the outside but the inside could be a different story.  Chimneys deteriorate from the inside out.  So even though the outside looks good the inside, the flues, could be cracked and allowing poisonous gasses into your home.

Second, prices are going up.  As you can see, we are the cheapest online because we are the manufacture of the chimney liner.  But our prices will increase soon.  So buy now to save money and keep your family safe.

Terra-Cotta Top Plate

When you have a terra-cotta flue that extends out of the chimney, a terra-cotta top plate is suggested.  The top plate will wrap around the sides of the terra-cotta and secure to the outsides of the flue using 4 bolts that are adjusted tight to the flue.  Using this top plate is recommended when the terra-cotta is extending above the chimney because many times if you try to break the flue, it may crack the crown. terra-cotta top plate, chimney liner top plate  Terra-cotta top plates are available for all common flue sizes.

When would you use a Rigid Chimney Liner?

You would use a rigid chimney liner when you want the BEST.  You would also want use rigid when you are using it for a solid burning appliance (wood, coal, pellet) that is your main source of heat.  One requirement is that your chimney be straight, free from bends.

What benefits does a Rigid Chimney Liner have?

A rigid chimney liner is strong.  You have the peace of mind that you have the best chimney liner on the market inside your chimney protecting you and your family from harmful fumes and a chimney fire that can be contained inside the liner.  Also, when you have a wood stove you want the best draft possible with as little creosote build up.

The rigid is a perfectly smooth inner wall.  Click HERE to learn how a smooth inner wall benefits you.  Rigid chimney liners can take a very aggressive cleaning, which means when you are done cleaning there should be absolutely nothing left in terms of creosote.

When would you use a Flex Chimney Liner?

You would use a flex chimney liner when your chimney has bends in it.  The flex is your only option in this case.  But there are a few styles of flex liners available.  This page will describe the difference between two of them.  If you have a gas furnace, this will not create creosote, so a flex liner may be sufficient in your case.

What benefits does a Flex Chimney Liner have?

Flex King Vs. Flex King Pro

Categories: Tags:

Flex King Vs. Flex King Pro

Many people see our Flex King and Flex King Pro chimney liners and wonder what chimney liner is best for their application.  There is no one answer that fits all.  Lets talk about when you would use a Flex King or a Flex King Pro first for a wood stove, then an oil furnace and finally a gas furnace.  You can clearly see the differences between the Flex King (on the left) and the smooth inner wall Flex King Pro (on the right).

flex king, chimey liner interiorflex king pro, chimney liner interior, smooth wall chimney liner

Flex King Pro for Wood stoves

Generally we will say Flex King Pro is the best liner for wood stoves.  This is because it has a smooth inner wall.  That smooth wall creates for better draft and less creosote build up.  So if you plan on using your wood stove for more than just the occasional fire, the Flex King Liner is what you want.  If you are not going to burn your stove regularly, possibly just here and there on weekends, the Flex King will work just fine for you.  One thing you need to use, no matter what liner you install for your wood stove, is insulation.  Click here to learn why it is required.

So the verdict is if you burn more than here and there, install the Flex King Pro for your wood stove.

Flex King or Flex King Pro for Oil

Oil furnaces can go either way.  Sometimes it is recommended to use a Flex King Pro and other times a Flex King.  This is mainly determined on how well the furnace burns.  Sometimes an oil burner can be sensitive to draft, especially when the chimney is shorter than normal.  Sometimes the oil burner does not burn very clean and creates a thick soot in the chimney.  This can lead to a blocked chimney.  We highly suggest hiring a furnace specialist to clean and adjust the furnace immediately.  So if you have no issues with draft, your chimney is plenty tall enough and the furnace burns clean you can use the Flex King chimney liner.

Flex King for Gas Furnaces

The modern gas furnaces burn fairly clean.  When there is perfect combustion water is one of the by-products.  This is not just any water, it has acids within it.  This is no good for masonry chimneys.  The masonry will soak in the water and the acids will quickly eat away at the terra cotta flues and the bricks or blocks.  To prevent this damage you need to install a Flex King chimney Liner.  Some high efficient furnaces have cooler exhaust temperatures so the water condenses quickly inside the chimney.  In rare cases the water condenses at such high rates inside a cold chimney, water can be seen leaking out of the bottom of the chimney.  If you have this problem, you will need to insulate the chimney liner to keep that water inside the chimney as a steam.  This will prevent it from condensing and causing more problems.

If you have further questions, please contact us. We will help you decide what Flex King Liner will be best for you.

Why do you need a chimney liner?

Why do you need a chimney liner?

You may ask, “Why do you need a chimney liner?”.  You may think that your chimney has been there for almost a hundred years and as far as you know it is safe.  So why is my chimney sweep telling me I need to install a chimney liner now?

Chimney liners are designed to keep the harmful gases of your furnace or creosote from the stove inside the chimney and keep them from entering your home. Many homes have a chimney with very old technology. They have terra cotta (clay) flue liners. They were designed to work with coal, they still do work for coal. But now very few people burn coal as a main heating source.

Why do you need a chimney liner if you are burning gas, oil or wood?

Today many people burn natural gas and home heating oil. The terra cotta flues were not designed to withstand the acids inside the exhaust. Wood burning stoves create creosote, that when hot, is a flammable liquid. This creosote can be seen in the picture leaking into the home.  This is an extremely dangerous chimney.  As you can see the flammable creosote is now entering into the home and can easily ignite, catching the home on fire.  With gas and oil burning appliances, eventually the terra cotta deteriorates, creating he possibility of the chimney flues falling over inside the chimney.  This will creat a blocked chimney, a very dangerous situation for your family.
Why do you need a chimney liner
You need a stainless steel chimney liner, it is what will stand up to the harsh exhaust from a modern furnace and the dangerous creosote from a wood stove.

Burning wood in your chimney


Here is a nice video which talks about seasoned firewood. It’s not good to burn wet wood. It will create creosote build-up. Creosote build-up is not good. It can lead to a chimney fire if left unattended. If you have a stainless steel chimney liner in your chimney you still need to clean your wood burning chimney regularly. If you have a corrugated chimney liner the build-up can be more extensive.

Wet wood will burn. It will just burn poorly. It will produce a lot of smoke, and won’t produce as much heat as it should. Many people like to turn dampers down at night so that the fire doesn’t go out while they sleep. This is really a bad idea if you want to keep creosote build-up down.



Did your heating season start late?


This year across much of the North East the cold weather/heating season started a little late. Last years heating season was also relatively mild. This caused many homeowners to use their heating systems a lot less. This meant them believing that they did not need to have their chimneys serviced.

Despite how much you use your chimney during a season, you should have it inspected/cleaned yearly. Over the summer months many different things can happen.

You may have decided this year to install a wood burning insert or pellet stove as many homeowners have. Did you know that you are required by the manufactures and national codes to install a chimney liner with each wood burning insert, no matter what condition your chimney is in.

Chimney Liner Depot has the best selection of chimney liners on the market. Call us today to speak with a technician who can help you with your chimney liner installation.

Rigid Chimney Liner for wood stove


If you are thinking about relining your chimney with a stainless steel chimney liner, you should seriously consider lining it with a rigid chimney liner. A rigid chimney liner is nothing more than a stainless steel pipe. It is not flexible and comes in sections that you connect during installation. It provides a glass smooth chimney liner that will make it very difficult for creosote to build up if you are burning wood. Creosote build-up is bad, but unavoidable. If you reline your chimney, you can keep the creosote build-up to a minimum. Call us today to find out how affordable a diy rigid chimney liner installation is.

Chimney Liners Love Cold Weather

    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If there is a terra cotta clay flue liner, does it protrude out of
    the top of the chimney at least 2 inches? If there are at least 2
    inches and the terra cotta clay is in good condition, you will use
    our stainless steel, terra cotta top plate that has a 1 1⁄2inch edge
    that goes all the way around (like a shoebox lid).

    *If your terra cotta clay flue is in bad shape at the top, you may
    need to just take a hammer and tap all around that terra cotta,
    taking it away to make the surface flat at the top of your chimney.
    In that case, you will simply use the flat top plate that comes with
    our liner kit.

    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If it is on the back of the stove, is it parallel with the back of the stove or is it at an angle, like 45 degrees?

    *If it is at an angle you will use an insert stove adaptor (an insert liner kit) rather than a two-part tee with cleanout cap.

    Usually pellet stoves have an exhaust hole id of 3 inches. However, if you are going up more than 15 feet to the top of your chimney you need to use a pipe and/or flex liner that is 4 inches diameter.

    If you are only venting a hot water heater then the exhaust hole diameter is probably 3 inch diameter. If it is 3 inch diameter and you are going up more than 15 feet to the top of your chimney, you must use a 4 inch diameter flexible liner or ridged pipe for proper draft. We also suggest to go ahead and use a 4 inch diameter flexible liner or ridged pipe even if the total length is 15 feet or less.

    Not the depth or any other dimension inside your fireplace.

    Most gas log fireplaces require an 8 inch liner kit or rigid kit. But do not assume that is the case for the gas log fireplace kit you are installing. Obey the requirements for that specific unit that are in your installation/instruction manual.
