    As a service warranty and commissioning engineer for both Rayburn and Stanley cookers and stoves I think I’m experienced enough to state that a chimney liner is essential to the safe running of a solid fuel stove. A liner keeps the flue gases hot and therefore moisture in it from condensing in the chimney this is especially important when burning wood or as in Ireland turf. If installing in an old chimney that may already be full of tar from this kind of fuel then a liner avoids the big problem of a chimney fires and in the case of wood or turf tar deposits along with water that had condensed in the chimney running down. I’ve been to many houses in Ireland where tar was running out of the soot box.

First, for safety, you are much less likely to burn yourself in touching twin wall and second, twin wall is less likely to cause a fire as it passes through ceilings etc. hope this helps 👍

    Scandinavian cast Iron wood burners have a 370 year history at the very least. A recent study in Norway, showed that burners designed over 150 years ago burn as efficiently as many modern clean burn designs and would achieve clean burn status. Many house holders don't know enough about how to use their wood burner correctly. I noticed that your fire is not making much smoke at all and that is the real aim; burn all the fuel and there won't be much trouble with the chimney. I don't have a liner in my chimney and I have thought of re-lining in the way you described for concrete, but with clay (which has been done here in Norway for generations). Interesting post, thanks for sharing your thoughts.

    I give them a proper education and the time they deserve. I allow them to make a well educated decision of fitting a liner. And I only use premium liners that withstand the acids. I always insulate for optimal performance. I'd love to collaborate with you on an educational video in the future. I am a second generation specialist and I feel we have effective communication. This is because our family took the time to educate us well. To serve others well. Not all sweeps are blessed with a loving father to answer all our stupid questions.

    Nice explanation, I was unaware of the tar leakage or the acid problem (caused by sulphur in the coal making sulphuric acid).
    I believe that a standard vitreous clay liner will be unaffected by the problems above but but due to the large mass the cooling effect will cause condensation and tar/creosote formation.
    I have always installed liners with vermiculite loose fill to enable fast flue temperature rise and better air flow but was always concerned that I was losing some heating effect and heat recovery from the chimney breast and surrounding masonry that is very useful in providing background heat to upstairs areas.

    • @TheTortoise
      @TheTortoise  Год назад +2

      Yea that’s true. The issue clay liners have is that they crack in the event of a chimney fire.
      The loss of the chimney thermal mass is a reality when insulating liners, but it has its upsides too.

    i have an 11m high chimney, it used to be mild steel when i bought the place. it was almost impossible to get it to start drawing as the cold air was 'falling' down all the time. when you opened the stove before it was lit, it felt almost like a gale coming down there. OK i exaggerate, but you could feel the cold airflow on your face. I then replace it with a stainless steel lined chimney and the difference is unbelievable. it draws straight away. my vote is definitely for a lined chimney.

  • @woollywhippet9899
    @woollywhippet9899 Год назад +2

    I tried without a liner and after two weeks I started to get an acrid smell in my loft conversion room where the existing 9” brick flue went through. With the smell came the dampness too. It doesn’t matter how dry your fuel is, there will always be moisture in the air that contributes to the oxidation process. 9” brick flues were designed for open fires that have the opposite efficiency throughput and output. Many people get away with this because they have a unused loft space and don’t notice what is happening. The condensation process still occurs but is less noticeable because of the increased ventilation in the loft space.

  • @izzzzzz6
    @izzzzzz6 Год назад +1

    I'm considering getting a chimney liner because of the creosote that often drips down after (i assume) condensation forms from the upper parts of the chimney being so cold. Really, i want to knock the entire chimney down as it pulls so much cold into the house. It really needs around 3M of uninsulated flue pipe to help heat the house and then insulated flue pipe for the loft and outdoor section.
    I've had all sorts of blockages and burned all sorts of wood but i try to run a brush through it 2 or 3 times a year. Concrete block chimney from 2nd floor floor with a flue pipe down to the fire on the ground floor.
    My fast clean is to go to the roof and drop a rope and carabineer down till it pops out in the stove. I attach the brush close the door and all air vents into the stove then go back to the roof and pull it through. I do this 2 or 3 times and sweep all the crap out while wearing a mask and running a vacuum from outside with a long pipe to around the stove (trying to catch any fine dust that might be in the air from the process).
    Really. This video should be "why you want to 100% remove your chimney and replace it with stove pipe"

    my house was built in 1952 and a boiler was also set up in the basement to burn coal but the owners back then quickly realized that the chimney got clogged too often with tar, and so in 1953 a pumice liner was put in the chimney, the brand was isokern and in fact the new smaller pumice liner that got installed here in the mid 2000s to replace the old big liner is also from isokern!! the old liner worked fine but since the big old boiler was scrapped there was no need for a big chimney liner anymore as the new liner is much smaller at 160mm instead of 250mm as the old one most likely was

    Hi. We are thinking for next year of having a wood burner installed in our fireplace, and this video has given us food for thought! My main concern is looking at your fire set and ours would be actually in the fire place would not all the heat go up the chimney rather than warming the actual room it’s in? We can see with your setup you have a flue pipe in your room that would obviously get hot and give off quite a bit of heat! Whereas ours the heat would maybe go straight up the chimney!
    Great video and we did enjoy the whys and wherefores ! Thanks for sharing! 👍👍

    • @TheTortoise
      @TheTortoise  Год назад

      Modern stoves are superb at driving heat forward. Heat off the flue is fairly pathetic compared to the stove, but don’t forget that heat within the fireplace is not lost. That will build up thermal mass and will act as a heat sync warming more of the house. Definitely no problem in a fireplace! 👍

  • @djones-np8ik
    @djones-np8ik 27 дней назад

    Houses like mine built around 1910 had fireplaces in most rooms, even the ones that weren't used often you needed to clean as the mortar degraded. Soot from the coal fires contains acid which ate into the joints even more snd eventually caused damage to the chimney stacks which had to be repaired. After 50 years of use bricks were very loose. Liners were a must when replacing an open coal fire with a gas back boiler.

    standard Coal Fires never had Liners , they were introduced to allow gases from Gas Fires /Back Boilers to vent quicker using the cross wind to suck any gases into the atmosphere

    • @TheTortoise
      @TheTortoise  Год назад

      It depends what you mean by standard coal fires. Anything open (eg an open fire) would never normally have a liner (particularly not a metal flue). It may be worth watching the video, because there are very good reasons for when and when not to have a liner, but I believe you’re mistaken on the purpose of a liner. Closed appliances have fairly slow moving flue gases and a cross wind will only assist draw in certain situations (in other cases it can make draw far worse), it can also only suck out as fast as air is going into the appliance, so with closed appliances this will have hugely varied results.

      That’s sounds great. Officially with an existing installation, installing a liner is considered a repair and therefore isn’t subject to building regs. As long as the stove was installed legally when it was first put in? That’s a bit of a forgotten rule, but it may make your installation simpler.

    I put in a 6" double wall stainless liner and filled the remaining stone chimney voids with vermiculite - the results are most visibly seen when cleaning the chimney after a winter - the only condensed smoke tar is at the very top of the chimney at the pot and hat... this is in north of scotland where you can see orkney off shore. The fierce wind condenses the smoke on the wind/bird guard at chimney top - that's my more serious problem - the tar at the very top gets frozen by the icy winds and it clogs the wind guard - even blocked the entire chimney one january... never regret putting in the liner though.

    We fitted a woodburner in a coal fire grate which had an 8inch diameter terracota flue. We tried to save money by not fitting a liner but it was a false economy. The fire didn't draw well and we had huge problems with tarry condensate running down the flue and out the bottom of the fire making a pool of smelly water in the grate and staining everything. You wouldn't believe how much condensate there was. We now have a stainless steel liner fitted and its great. The fire burns well and there's no stinking water coming out.

    Great video. I certainly wouldn't want that liner shoving down MY throat!
    Back in the 90s when we got our first Clearview, we invested in an insulated concrete liner from Chimneycrete; the flue has three holes knocked in, one just above the lintel, one in the first floor and one in the loft space, and then a deflated sausage fed down and fixed to the register plate at the base of the flue, and inflated so it is pretty hard, Then, insulated concrete is gently pumped in through the bottom hole, and the mix carefully placed all the way around the sausage. This hole is then bricked up and the pump hose taken upstairs and the section between the bottom hole and middle one filled, making sure the sausage is kept central and the concrete fills all the spalling brickwork in the old flue. Same again from the loft space and then it's filled right up to the top of the chimney. The next day, the sausage is deflated and this leaves a smooth round flue, with a 100 year guarantee, which gives SO MUCH draw.
    When we moved in 2001 we took the Vision 500 with us, and bought a Pioneer 400 for the front room - and we got BOTH chimneys lined with Chimneycrete. Fabulous company, top notch product, we've had the stoves heating the house for over 20 years with no issues whatsoever. Recommended.

    In 1999 I had my gas fire and back boiler taken out and replaced with a combi boiler, so this left me with a open fire place. I put a small secondhand burner in which was fine at the time but after a year or so I noticed that tar was seeping through the bedroom wall. I decided to upgrade my woodburner with a new Charnwood 6 and put a liner in too. The difference it made was really good, I found by burning the wood a little bit hotter the soot and tar issues virtually stopped. Being in the tree business wood was never an issue, always the best wood going of course. When I moved house in 2007 I put a Jotul f100 in with the liner of course and never had a issue with soot and tar at all.

    Hi, back in the 1980s when i was young man we bought an old farm house near the sea in Ireland - seemed a good idea at the time - i spent a lot of money rectifying the old house - we removed all the old plaster throughout the house & had it re - roofed - re - wired & re - plastered -all looked great - a year or so later we arrived & started painting, it was quite cold in the empty house , my nephew said he would warm up the house by lighting a fire in the main sitting room - this he did, it soon warmed up & was quite cosy - my wife came & told us that she could smell smoke in other parts of the house where we had no fires - then my children said that smoke was coming out of the power outlets in the bedroom - we contacted the builder - he suggested that the main chimney should be cut open & the chimney lined with clay pots - I suggested a stainless steel liner - he said that the way the old chimney was built he would not be able to fit a steel liner - he would need to remove all the face of the wall up & out through the roof , cut out the irregular rock to make space for the clay pots & rebuild the chimney stack - as we thought that the house was finishes it came as quite a shock & quite a cost - but my wife loved the house so we went ahead with work - we now have a nice house & no smoke - it would of been so much easier just to put a steel liner in. Ed.

      I fitted my own Multifuel stove 10 years ago and didn't fit a SS liner.
      Because my chimney was sound and already lined with clay terracotta liners built in the late seventies.
      Made to BS EN 1457-1:2012 - Classification A1N2
      Clay flue liners have a proven durability, with an inherent resistance to corrosive acid attack and will last hundreds of years.
      Unlike ultra expensive stainless steel liners which only last a few decades.
      The reason SS liners are fitted is because most home owners don't know the durability and integrity of the flue/chimney they own and the SS liner is a belt and braces approach for the installer for insurance purposes.
      Of course the installer can test the integrity. But he doesn't trust those tests.
      And even if he did, the regulations won't allow it.
      A few years back a home owner sold their house and the new owner stripped the wall paper on the chimney breast exposing a crack. And combustion gases entered the room. I can't remember if anyone was affected.
      The regulators use these cases to tighten the regulations.
      As the SS liner method is part of the regulations now, the home owner pays the extra cost or just lives with their current open fire.
      If you employ a technician to test your current open fire flue and it passes all the tests . Fine and good.
      You can get a different installer/technician back the next day and tell him you want to fit a new stove.
      He will then inform you that your flue isn't fit for purpose and needs a SS liner. Without doing a single test.
      What he won't tell you is that the SS liner will eventually fail anyway.
      In Northern Ireland new builds have to comply with the fitment of SS liners.
      Anyone selling or installing stoves have to tow the SS liner line.
      A private individual like myself does not.
      Of course I will get accused of endangering my family and myself and making my home insurance void. Even though I don't have any insurance.
      But that is my choice and I still have the freedom to do just that.

    • @TheTortoise

      The fan and thermometer safe available on our website:
      thetortoise.net/
      The fan is about stirring the heat around your room. Stoves are mainly radiant heaters so getting air movement does improve their effectiveness. The thermometer is particularly useful to new users as this teaches you how hot to keep your stove when running it. This is important because like a car the temperature is key to things operating efficiently.
      With regard to maintenance, in the main this will be reviewed by your chimney sweep. These guys are looking closely at everything from the flue, to the spares and repairs needed to your stove, so they are the best people to ask this on their visit to you. Generally it is a good idea to have your stove swept before the cold months and then after Christmas, from there he can advise you how clean things are and whether you should continue sweeping regularly or switch to just 1 a year.

    I will add my experience. I contacted my local stove company and got a quote to supply and instal into the existing and modern 9inch flue. I did all the preparatory work creating the space. Every thing was perfect for the installation. The converter piece between stove flue and chimney just didn't fit. The installer overnight got another one made and that didn't,t fit. The option was to fit a liner which was done on a materials only cost. I am still a bit miffed that the stove firm and installer ,reputable, had not got a standard solution for a standard build. It does all work well but on still days when newly lit smoke inverts and doors and windows are opened to create a draught to get it going.

      Rather annoyingly lots of modern stoves will spill smoke into the room, particularly when they’re cold. If you watch my reviews in the “controls” section I will often mention whether it spills during re-loading for this reason.

    The standard thing here in Germany, at least in houses built in the 90s, seems to be a kind of liner inside the chimney, but constructed from square-section ceramic pipe in roughly 60cm lengths, forming a column inside the chimney. The pipe’s around 25cm square. The sections are sealed with one another with mortar, and the whole thing’s insulated with mineral wool. Anyone seen anything like this outside Germany?

    • @TheTortoise
      @TheTortoise  Год назад

      When building chimneys we have something similar, but depending on its diameter we will often put metal flues within those: Ceramic, Concrete, Pumice liners. We will tend to insulate those masonry liners with vermiculite, glass fibre wool etc is also commonly used.

      The advantage with a metal flue is it’s a quick and simple fix when it fails. The ceramic flue is almost certainly perfect as is, but when it fails it will be a nightmare, so lining with metal is a good answer. But this is perhaps me being a little particular, given that most people don’t live in 1 place for decades. In these cases the use of a metal flue simply benefits the next owner of the house.

    Depending on what you burn out of necessity, you will still get chimney fires inside the liner, at the chimney pot end, due to build up of tar/soot.

Just let your fire die down and get the chimney swept, the tar will burn itself out.

    Another thing I'm curious about is if these wood burners have air fed to them from outside? I know of at least one house that was specifically built with a flue that ran from outside to under the fire, with a damper of some kind. Having lived with open Coal fires for many years in the past, the horrendous draught that they cause wastes much of the heat they generate. We used to see the carpet rippling from the blast of air coming from under the door from the hall. It seems to me this ought to be addressed in every installation. After all, the air has to come from somewhere, and that shouldn't be through leaks into the house from poorly fitting doors and windows.

    • @TheTortoise
      @TheTortoise  Месяц назад

      Most houses do simply leak a bit, so the rule is that no extra air is required up to 5kw. Nowadays people are often fitting stoves with “direct air” meaning that the pipe of incoming air is directly attached to the stove, therefore causing no draughts.

  • @miketurner3964
    @miketurner3964 Год назад +5

    Not sure what’s happening here, most comments miss the major issue.
    Open fires, inherently have low flue temperatures- Stoves don’t.
    After a few hours running a stove can happily heat bricks to whatever temperature the stoves’ running at.
    This over time destroys the withey’s (which are only brick width) causing flue gases to get into the other flues in the stack, but the worse case scenario is where the chippy back in the day trimmed his joists into the 1st floor (and above) stack and generally couldn’t give a stuff how far they went in.
    An uncontrolled burn, stove door left open for example, turns the stack into a giant pocket warmer.
    The joint ends heat up, combust and there’s your bedroom or roof fire.
    The reason the roof goes regularly is that the top third of the chimney degrades fastest due to moisture and corrosion from when it was on open flue.
    Hot gases will also leak out of degraded mortar joints, again heating up anything they come into contact with.
    Get a liner, then you won’t be arguing with the loss adjuster about what RUclips said.

    All I will say is that I never had a liner when I had a wood burner. It went straight from the back of the burner into the chimney (with a fibreglass packing around a fireproof material). We used it every day as soon as the summer ended with no problems whatsoever - I mean none: no blow backs, no condensation of the chimney in the loft, nothing. It pulled the fumes brilliantly. We only took it out this year as we got fed up sourcing logs. If you want to get a liner, fine.

      I appreciate what you say, and all I can say is my experience. I'm a heating engineer, not a solid fuel engineer. I did inspect the flue before and after, and it was in for seven years with three cleans. I experienced no problems for having no liner.
      Our burner took the place of an open fire for decades before. I cannot see any difference the liner would make. I think if your flue didn't pull well, it would help, but that's about it. If I were doing it again, I wouldn't put a liner in.

      Probably worth watching the video, because the affect it has is precisely what the video is about. Some people believe that a liner is to make things work better. It may do that (as you say) in some cases, but that isn’t it’s purpose. The problem a liner solved is a bit like the mouth guard in a boxer, or the bumpers on a car, at some point you will wish you had it.
      I talk about this in the video, but the issue with stoves is (unlike an open fire) the flue gases move slowly (watch the video and it’ll make sense, I’m really not trying to sell them, it makes no odds to me).

      As I said, all I can do is tell you and others my experience...that not having a liner didn't cause any issues. I'm not saying people shouldn't have one, or that they are a waste of money. All I can go by is my own experience, and it's why I wouldn't have one again.

      Unfortunately it’s like asking how long your tyres last. 1 person will kill it in 5 minutes another could have it for decades. As I grew up we had 1 heat source (a wood burning central heating boiler stove), and it ran 24/7 for 7 months of the year and sporadically for the other 5 months. It was used like this for 30 years and then got pulled out, but only because my father was letting that property so brought it up to modern regs. 904 is not necessarily the best at all, the grade sadly has no bearing on life expectancy, it is all about use. My 316 liner lasted 30 years and was still going, but a 904 liner will suffer mortal in 1 hour at 1100°C, so it’s far from a simple answer.
      So generally liners last a very long time, but let’s say the stove ran for an average of 2 hours a day (every day), in a dry chimney, with dry fuel and a perfectly run stove. It seems plausible that the liner would last the life of a stove which is potentially decades and decades, in fact in those situations it would almost certainly outlive us all.

  • @glynluff2595
    @glynluff2595 Год назад

    Well look at how houses were constructed for hundreds of years and I have had all sorts of chimneys from 1700 or so. All buildings until post WWII were constructed from brick bonded with lime mortar which has the ability to flex slightly until intense heat causes it to shrink and allow penetration of smoke. A large chimney stack and the base has to be large to accommodate the mass of brick which can mount on top with other fire places. This mass becomes so cold it can take weeks of fires to warm it in a large house with only one fire in a stack of half a dozen flues. This can be reduced to a feasible value by inserting a flue liner and inserting an insulated jacket around it. This allowed the smoke to exhaust without deposition of tar because there was no thermal condensation. There is also the point that the liner life can be reduced by consuming coal which will rot the liner from the acids it contain. The liner needs to be swept annually to remove the ring of condensed tar which tends, still to build up on the chimney exit and to prove this a sweep will issue a certificate which insurance companies now require if there is a chimney fire claim.
    Is it a confidence trick? No it is basic engineering especially as old houses are no longer used in the way they once were.

    Since I've installed a pretty large stove, (~8 kW) I'm hoping (and this seems to be working in practice) that the volume is sufficiently small for the stove to be able to get the chimney to draw.

      My chimney guy wants to install one in my gas burning hot water heater and gas burning furnace line (chimney line) in Brooklyn NY 1901 Victorian house. $5000 I’m I being scammed? This guy in the video didn’t say anything other than wood burning stove line needs this liner? Help!

    Great content, appreciated. Can you explain what happens if a 'cowboy' home installer doesn't attach the liner to the top of the chimney pots but rather shoves it up.from the inside and as its the same diameter as the clay pots on the exit stack, leaves a gap for smoke and condensation to come back down. Am i correct in thinking that this could be a problem. This lad wants to do it his way. I suggested that the liner needs to go all the way to the exit point and be fastened securely.

      This is a tricky one. Honestly in my own home it wouldn’t necessarily panic me at all. Obviously there are rules in place and this wouldn’t comply and therefore you couldn’t sign it off, so none of this is potentially legal. This would obviously lead anyone to say “you can’t do this”. However regs have only been in force for 19 years and prior to this it wouldn’t have concerned me in the slightest.
      Obviously in your case the proper answer is to remove the pot. Secure the liner with a top plate and clamp, fit a new pot on top and then best practice is often to vent the stack by drilling through it with the drill on a slight upward lean so that air exchange is possible, but water cannot run in.
      The flip side is if you’re getting this signed off by a building inspector, I’m sure you’d get away with doing your original plan, but then you’ve got to live with it. Building inspectors will be exempt from prosecution in these cases so if the installation did harm someone, the installer would remain legally responsible (I believe).

    Hi Gabriel.. do you why we have we gone from 6 inch to 5 being the standard these days on average sized stove

    • @TheTortoise
      @TheTortoise  Месяц назад +1

      Yea it’s a strange one. Previously all anyone did was fit 6” because it was, and still is the best option in most cases. However in 2011 (from memory) DEFRA approved stoves were introduced, and with it, they banned the use of 5” with any stoves that weren’t DEFRA approved. This created unusual interest, as there was now a barrier to overcome. If someone bought a DEFRA stove, they would typically have paid more and they wanted the benefits including 5” flue. Now clearly 5” flue is not actually a benefit for anyone but the shop, because they cost less and are easier to install (there are some cases where smaller flues are an advantage, but that’s another subject), but the barrier, mixed with the sales patter of the industry caused a massive increase in 5” sales. Things like:
      It’s cheaper to buy
      It’s easier and cheaper to install
      You can have it if you buy the upgraded and more costly DEFRA version.
      Your chimney is short, so will benefit from a smaller flue.
      Your chimney is tight, so we may be forced to use a DEFRA stove and a 5” flue.
      It became a big talking point in shops, so sales went with it.
      I remain an advocate for 6” flues wherever possible, and suitable, but it is slightly more costly and trickier to install due to bigger weight, trickier to carry up a ladder and to shove down a chimney.

    Firstly thank you for such an informative video your videos are easy to follow and answer most of the questions I have on various aspects of buying a stove. When we brought our current home it had an old oil burner stove in the fireplace which was not in working order and so removed. My question is would the liner that is in the chimney that was for the old Efel oil stove be ok for a use with a multi fuel stove or would it be safer to remove it and put a new liner in?

    • @TheTortoise
      @TheTortoise  Год назад

      Sadly it will almost certainly need pulling out. Firstly there is probably a certification issue, and it may well not be appropriate to solid fuel.
      Does the current installation have any paperwork that details what was fitted and when?

      A good sign is always if it is drawing and working. Generally if it isn’t broken then you don’t need to fix it, but where you’re talking about masonry liners the best advice is fit a metal flue so you don’t break it.

    originally had a gas fire converted to an open fire we use in cold snaps so fairly often in winter.
    It’s swept professionally yearly.

    The chimney is lined with clay pots.
    Would I still need a liner?

      This may be true, but on the other hand you’ve had 2 stoves over a few years, this level of experience is simply not enough to form an argument from. It’s like saying driving at 150mph on the road is safe because I’ve done it, and I just change my tyres once a year.

    My first log burner was a small Queen stove. It has firebricks inside so could be used for wood or coal. It was out in the kitchen of our house in 1980. It made such a difference to the whole two up two down house! Fast forward some twenty years or so. While on holiday in France saw a lovely coal stove in an antique shop. The mica was broken in the doors, but apart from that it was fine. Got it for a good price. Green enamel and porcelain handles. I cleaned it up and bought new mica from a stove shops in Essex. It is not used now, just as a feature as it has been condemned by the sweep as there is no liner.
    In our house in France we have a Godin with a liner. It's been in about 16 years and is just used in the Winter for ambience. It has a new liner on installation. Can you give an idea of how long liners last?
    We are big fans of lightening stoves.

      Liners are like tyres on a car in that you could destroy them in a day. But I’ve known liners still be serviceable after 30 years.
      If you look after it, use it well etc, then I generally think that 20-30 years is more than possible.

      No need to worry too much. It should last a good while yet and the blacking at the top of the chimney is probably down to old tar etc. Your sweep is the person to ask, so if he hasn’t mentioned anything then I wouldn’t worry too much unless something changes with the draw, or the stove stops operating normally.

    I’ve always fitted liners. I’ve a Jotul 602 and my neighbour has one also. He has a board at the back of his, I can boil water or make the supper, his doesn’t! Another difference is the modern stoves are far more efficient with the smoke getting recirculated. We also have a Jotul 105 and after ignition, we can’t even see smoke it’s so clean. A liner is a necessity alright 👍

  • @markthomasson5077
    @markthomasson5077 Год назад

    One point he has missed altogether is that the air travelling up your chimney dries out the chimney stalk and chimney breast - particularly in the loft space. Fit a stainless steel liner and this no longer happens. So you get damp walls inside. Especially if you plug the chimney base to stop draughts
    Of course the issue with tar largely stems from the use of low quality house coal, which is no longer allowed, at least in most places.

    • @TheTortoise
      @TheTortoise  Год назад

      Good practice when installing liners is that you vent a chimney at both the base and the top, which will prevent the damp issues you’ve described. With regard to tar this has dozens of causes, and was never specific to coal, but one of the main causes is damp fuel. What a liner does is provide a small and smooth surface that tar can run back down into the stove. The other thing a liner corrects is that it heats up quickly meaning that any tar is much less likely to condense on it. A chimney on the other hand is larger and masonry so condensation on a chimney is not only more likely, but it will also cause a lot more due to the cooler temperatures.
