"Thank you very much for installing the cowl on my chimney. I have now been using the woodburner with the cowl fitted for about 3 months.
1 The fire lights and draws much quicker than previously, particularly on cold windless days.
2 I used to use coal as a base in order to get a hotter fire and draw but now find this unnecessary.
3 The woodburner seems to burn hotter and appears to burn longer for the same amount of wood. A small but financial miracle!
I must say we are both delighted with cowl and it does not look unsightly or out of place on our period property chimney stack.
Thank you very much for the cowl and I wish you success with your product"
"“Having removed the seized up, so-called spinning cowl and replaced it with FlueCube we have notice there is less smoke, less down draft, burns cleaner and it now copes with wet and blustery weather, unlike the previous cowl when the house would have been smoked out! Excellent piece of kit.Thank you. "Ian & Caroline Russell

"It does exactly what it says on the tin. In fact it worked even better then I'd expected when I installed it for my Scan Wood Burning Stove. "Nik Antcliffe Old Flames of Beverley
Following advice from Mr. D. Higgins regarding problems with atmospheric conditions in the Angiddy Valley, Tintern, Monmouthshire I have recently purchased a new wood burning stove and installed as the manufactures instructions, chimney lined and insulated and fitted with bird guard on the top of the chimney. However, on lighting the said stove I was confronted with a room full of smoke as no draw was happening on the chimney, most dismayed at the situation I spoke to David Higgins who supplied me with a Flue Cube, I am delighted to say that since this have been fitted it makes no difference to what is happening in the valley outside, my house inside is free of smoke. I find that this helps greatly to the workings of my wood burner. If the weather is in the right direction I can close the damper and have moderate burning. I am sir, delighted with the performance of your cowl and would recommend this product to anyone with a wood burning stove.
"From Des Walker Chimney sweeps, Bristol.
We had customer with a new wood burning stove that was suffering from a poor draw and constantly blackening doors which, as the stove had large all surrounding glass windows was problematical for the owner.
We tried a number of the usual remedies to no avail and then decided to try the flue cube, somewhat sceptically I have to admit.
The fitting of the cube was fairly involved but the results have been very surprising for us: more heat generated, significantly improved draw, easier to light, less ash and a near total eradication of the door blackening.
We would certainly recommend this cowl if faced with this type of issue in the future.

"The main problem my dad was having with his Tiger stove was the smoke it was producing. The stove is in a single storey extension with flat roof and the neighbour was complaining the smoke was blowing into her kitchen! Even using wood that was purchased as "dry" it was smoking and also it didnt seem to be drawing properly and smoke was backing up through the vents into the room. As soon as the Cube was fitted we lit the stove to see if it had resolved any of the problems. It took about 4-5 minutes for the stove to warm up and then the smoke just vanished leaving only a heat shimmer visible..The smoke hasnt come back into the room either so hopefully this problem has stopped too.. My dad is more than happy with the cube and would happily recommend it/you to anyone"
You may remember we spoke by phone on 2/10/12 when you kindly offered to give me a Flue Cube so it could be trialled on a Tortoise firebox open fireplace.
Gary Evans installed it earlier this week and I'm pleased to say it has been successful.
We have an external redbrick chimney built around 1950/55. After fitting the firebox, from Ashtead Fireplaces, we were unable to light a fire without small puffs of smoke coming into the room every 30-60 seconds. It drew for 90-95% of the time but the smoke coming in made it unusable. Gary first thought it was a bird's nest and swept the chimney but found nothing.
After fitting the FlueCube, there were a few puffs of smoke at the first lighting for a couple of minutes but it soon started drawing without a problem. The second time of lighting the fire, there was no problem at all and I've even been able to close the Tortoise damper without causing the room to fill with smoke.
There was no real explanation before fitting the Flue Cube as to why it puffed smoke occasionally - theories being external downdrafts, a nearby tree, the nearby sky dish, etc. But the Flue Cube does appear to have made the difference from a marginally working chimney into a properly working one.
I hope these results are useful to you and thank you very much for the cube.
As you no the Fluecube was fitted Tuesday and good ole mother nature has obliged by throwing a mix of weather at us ever since! We’ve had sleet, snow, heavy rain and today it’s rather blustery not gale force but it would have made me think twice about lighting the fire with the previous cowl on there.
The first 2 noticeable differences since it was fitted is that there is no longer a draft coming from the fireplace into the room which I always had before and secondly on wet days you could always smell a damp sootiness in the room which could be quite strong and unpleasant now that has gone too! Brilliant.
The chimney sweep was curious to see how it performed so once fitted we lit the fire which hadn’t been lit for well over a week. The day was cold, dry & bright with a gentle breeze normally I would get smoke blow back until the chimney had warmed up and flames were roaring but this time the draw was instant, way better than ever before. I was obviously impressed as was the chimney sweep after I explained how it used to be, he said it was an excellent draw and wants to be kept updated on it’s performance as he thinks it would be good for some of his customers so I will be emailing him too.
Today I couldn’t wait to try it as it’s been quite windy and as I said before I probably would not have the lit the fire with the old cowl as I would have been smoked out! Well not today once again the draw was immediate it was like I was watching tennis as my head twitched from watching the wind outside back to how the fire was performing and it was again absolutely fine I am thrilled to bits it really does seem to be making a noticeable difference.
I will keep you informed of its performance in varying weather conditions especially when we get the really high winds. For now though I think it’s performance is just brilliant and would not hesitate to recommend this to anyone suffering issues with their open log fire and would happily speak to anyone to confirm this is a genuine testimonial regarding a test that is so far proving successful.
"..My own experience of the flue cubes have been hugely positive and they are a super piece of kit for problematic chimneys and I have experience of many different cowls and these are in another league.

"Just fitted my first FlueCube – Single story extension, twin wall 8” above a flat roof, house directly behind with high wall, front of the extension over looking an estuary. Customer has a wood burner his previous cowls have been, anti downdraft then spinning then box, all without success! After FlueCube installation, lit straight away, stove burnt clearly and no back draft. I am impressed and my customer is very happy
"Very happy with mine, Ive had to burn wetter wood than I wanted this season. The fluecube seems to get the exhaust up and away better. Last year our smoke drifted down and swirled around alot. So no worries about the neighbors. Plus I reckon you do get a better burn and airflow. Hard to prove without taking on and off and doing it in different weather conditions. I'd like to know more experiences, after all a collective effort will bring about better product development and usage."Goaty
""A customer of ours had a complaint, from a neighbour, of smoke from the chimney causing a nuisance. We installed the Flue Cube and the issue was, well, no longer an issue. Problem solved and both parties happy. Great product". "D Bucknall, Warm Knights Ltd, Worcestershire
"Very good results thus far the client is very happy with the improved burning and less down draft.
Many thanks for your help ,i look forward to fitting more cubes if it makes all my clients this happy !
"After installing a stove with a flue liner, the customer wasn’t happy with the look of the stove so quickly paid me to install another with the same output.
It was a ( new off the line direct air feed type of stove ), every time the door was opened when lit smoke would spill out into the room.
The manufacturer acknowledged there was an issue with this stove and even after the baffle was reduced twice the stove was still not functioning adequately for me to sign it off. At this point the customer’s house smelt like a bonfire so he was ready to remove it and put his old stove back in.
As a last resort we tried a Flue Cube, with instant results the stove pulled correctly even with the door open and the glass stayed clean. Within two weeks the customer’s house smelt fresh again.
I will definitely be using the cowl again in the future.
"“After installing a FlueCube we have noticed our wood consumption as gone down considerably
And it looks great – very state of the art –are we trend setters?”
"Just a brief note to say we had a FlueCube fitted. It has helped the fire start and draw much better.
It has also stopped the rain coming down the chimney.
"“My customer complained of the noise her chimney made in high winds. We tried a number of different cowls to overcome this noise issue to no avail.
We then fitted the FlueCube and the problem is now solved” "
"What was odd is the chimney was in perfect condition it should not have needed an atmospheric chimney cowl. For some reason we could not identify we had a massive downdraft problem. We tried the standard spinning cowl. This did not solve the problem. So we installed the FlueCube. Instant result; problem solved. The FlueCube is clearly a superior cowl. "Richard Ryder. FBS Flues & Stoves, Wincanton.
"I found the FlueCube easy to install an most importantly; it worked! "Steven Howard VP & Director of Training NACS
"Lincolnshire is very flat built on reclaimed marshland. My customer lived in the middle of the fen exposed from all sides. The main building was a lot taller than the smaller building with the chimney. The downdraft was created by the taller than normal roof of the taller building and the difficulty in getting the Hunter 24KW up to temperature. I tried the usual square anti down draft cowl then the spinning cowl. Both failed to solve the problem. On installing the FlueCube we knew instantly the dynamic in the stove had changed as we could tell the downdraft had gone before we even lit the stove! Needless to say on lighting the stove the problem was solved. I also fitted the FlueCube on my own home a bungalow the chimney was the correct length but every time a south easterly wind blew in from the sea across the flat terrain we would get a downdraft. Problem solved with the FlueCube. "John Booth Services.
"In October 2012, I purchased and had professionally installed a well known brand of inset multi-fuel stove. The main intention was to burn kiln dried wood with smokeless fuel as a
backup if the need arose. The stove burned very unsatisfactorily almost from the start and
my wife and I were very disappointed.
I spent many hours researching how to improve the performance of the stove and I came across the FLUECUBE cowl. On reading the information about this cowl it seemed to resolve the problems I had been experiencing. I then spoke to Mr. Martin from FLUECUBE who was very helpful and supportive in trying to resolve my problems. Mr. Martin suggested a local FLUECUBE fitter and I ordered the FLUECUBE the following day.
The first time we lit the stove after the FLUECUBE was fitted, the improvement in stove performance
was so obvious. The stove is now a pleasure to use. This improvement as been sustained over the
following months and I have no hesitation in recommending FLUECUBE to anyone who has a stove.
We are thrilled to bits with the new cowl - can't believe the difference it's made.
The room gets really warm now (hot, in fact). The stove ticks over just nicely, using less wood than before but giving out loads more heat
You don't have to keep jumping up to refuel, adjust the airwash, open/close door etc., like we did before.
I've taken your advice and keep a nice thick bed of ash now. Also, the floor vent is left uncovered all the time now - because the room is
so nice and warm, you don't notice any draught.
Since you fitted it we have had strong south/westerly wind, north/ westerly, no wind at all and heavy rain - none of which made any difference at all to the way the stove performed!
We're so glad you happened to have that fluecube on your van that day! Suggest you always carry one with you!
Thanks again for all your help and advice.
I'll give you a call in the Spring.
We have been using the Rayburn (on to which we fitted a Flue Cube in the summer) for a couple of months now.
There is a lot less smoke and it seems to be burning more efficiently. Obviously there are lots of variables and it is difficult to be quantitative, but our initial reaction is that it was a good investment.
"Hi. Registered last night with you & got trade details today thank you. I fitted my first one this evening in Hingham for Mr Bacon, I believe you have spoken to him. He has a brick chimney with clay liner that had been built on a new farmhouse. When I fitted the stove there was such a bad down draft it smoked the room out. I thought that the chimney was going to have to be doubled in height to get over the problem. We fitted the cube tonight and warmed the flue, put a smoke pellet in and pooff the smoke was gone!!!
I could not believe my eyes. We lite the fire and it blazed away.
I will defiantly be recommending these to my customers with problem chimneys.
The local chimney sweep fitted the flue cube in October 2013 and it has worked perfectly ever since. In the high winds we have had recently there was no back draught. Previously we would not have been able to light the fire. We are burning smokeless fuel on an open grate.
"Hi Ashley,just had to tell you what a great success the"Flue Cube" has been to us, we have gone from a non-drawing, smoking wood burner to a super efficient fire, we can`t thank you enough for your excellent service&help we will certainly be recommending the "Flue Cube" to all.Thank you."Edward&Diana Watson
"Hi Ashley, Good to speak to you the other day. I installed the 'Fluecube' last Saturday and lit the fire up Sunday evening during a very windy spell in the weather.
I didn't preheat the flue as I normally do to get rid of the column of cold air in the twin wall chimney. The fire lit first time and burned really well. No smoke entered the living room as is so often the case. The initial kindling timber instead of burning rapidly away burned in at a much slower pace seemingly undisturbed by the wind from outside. Normally the flames would be frantic inside the stove if it is windy outside.
Much less smoke is visible from the chimney since it has been fitted. Also the fuel seems to burn slower than before since the combustion is not being affected by the weather outside.
Yes it is a quality product really nicely made and 316 stainless steel is top notch stuff. It fitted really well and I have bolted it and strapped I to the existing flue arrangement.
I will keep you posted. But thanks again. So far so good. I have ready recommended it to a guy at the local builders merchants who lives in a bungalow with a short flue stack. I gave him your web address.
"Excellent:Great product when all others failed FlueCube delivered the fire is more controllable and blow back is a thing of the past we use less timber via being able to slow the burn rate since the down draft has been lessened. Product. Great product I would highly recommend. "Feefo - see more click on Feefo tab top of page

@FlueCubeUK in fairness the customer says the fire is burning loads better and is using less fuel since it was fitted. #itsa10fromLen

I just came in to see the fire blazing away merrily in one of the woodstoves. This was the stove that was a real horror to light, especially on a day like today when it’s wet and the wind is swirling around. Today (as always now) the fire lit first time with no smoke back into the room. When I open it up later to add logs, I won’t be kippered by having smoke coming back in. As you know, I was so impressed by the improvement that I ordered a second flue cube for the other less problematic stove, and it too now draws better. The design of the cubes definitely stops downdrafts, and the inverted cone shape inside increases the flow. I’m still not convinced that the description of how the design works is scientifically accurate, but the fact is the design works. Of course, part of this could be the extra height provided by the cubes, but whatever the reasons I now have two stoves that are easy to light, don’t smoke when opened or when down draughts occur, and that can be used even when the wind is from our problematic direction of North-North-East.
"There have been times recently when we would not even have been able to light the stove, Easterly winds for example it would have been impossible. Since we fitted the FlueCube on to our 8" twin wall it has been amazing transforming our stove experience. The stove now runs efficiently and yes saving on fuel it has performed just like you said it would. We are already telling our friends I hope you sell thousands. "Mr R Sharples Banbury.
"Being somewhat sceptical about claims made in advertising spoke to yourselves and subsequently ordered a Fluecube. This was easily fitted by our son and just over a week later the fire is working brilliantly, the most heat in the 12 years since it was installed, no cloud of smoke hovering throughout the house each time doors opened. During this week the only weather we haven't experienced is snow. Highly recommend this product.
"Hi Ashley - I've just lit the kitchen woodstove and the ease with which it lit reminded me that I hadn't reported back to you since the cube was fitted in the summer. We've had a much better experience with our stove this year - lighting has been much easier with far fewer of the problems associated with having a too-short flue (which as you know was due to the planners forcing apparently random changes on the building of the chimney). The cold down-draught seems to have virtually stopped, the fire burns cleanly and efficiently and lighting it has become far less fraught. Given the scale of the problems we had before I would not hesitate to recommend the cube to others, especially as its appearance is also far less noticeable than I thought it would be - we are very pleased indeed. Best wishes, Rosalind
"Hello Ashley,I would like to say that the result of fitting a FlueCube to my wood burner was immediate! The fire lit with no pre-warming of the chimney and had an amazing draw - I am so delighted after losing the will to live over the amount of smoke that was filling my room every time I tried to lite the fire. This FlueCube is fantastic and I have recommended it to my friends and the men who fitted it were very impressed and immediately rang one of their clients who was suffering the same as me with smoke filled room. I believe she has ordered one.
Thankyou once again Ashley from a very happy customer."
Just a short email to say the flue cube is a terrific success. The woodburning stove is drawing well and working cleanly for the first time for fifteen years. I have recommended it already to one other person and both the chimney fitter and the person who sweeps the chimneys are very impressed. I hope you get more orders as a result!
The Flue Cube arrived safely on schedule and has been fitted to the flue for our new wood burner which works perfectly - no blow back, good steady burn and everything it was claimed to be.
I recently fitted a FlueCube cowl to a customer’s problematic chimney which had been suffering from down draught problems and erratic burning for years. After a couple of weeks I received feedback that the stove lit easier with no back draught and burned at a controlled rate under various weather conditions. Problem solved!!. "
I went and had a word with the lady who had a FlueCube fitted on her Rayburn which was performing shall we say sadly.
But with the introduction of the FlueCube it has according to her "been a wise investment which has worked very well _ The Rayburn now works well and heats the water up to what it should do but the great advantage is that it now does not smoke.
So all in all she is very happy as she was sceptical at first but like she said It has been a wise investment and this Cowl actually works and does what it says in the small print.
"12 months ago I installed a Biomass wood pellet into a new build property near Devizes Wilts. Although the boiler worked well I was encountering real problems with smoke coming back down the flue, which also caused problems with flue temperature making the alarm go of on a regular basis. We tried rectifying the problem by adding height to the flue, installing a fan on the flue, and adjusting the settings on the boiler on many occasions, but nothing seemed to work. The boiler supplier was convinced that the problem was caused by atmospherics in the area, and suggested we try a new cowl on the market called FLUECUBE. We installed FlueCube three weeks ago, and it has transformed the problem. Since the FlueCube has been installed we have had no smoke problems what so ever, and also the temperature in the flue has decreased by a average of 30 degrees so the temp alarm has not gone off once since installation. I would thoroughly recommend the FlueCube if you are having similar problems.
": I have had a Aga for 6 years that has smoked every time we have a wind. I have fitted 4 different cowls all supposed to stop the downdraught but all with no success. I recently fitted a Flue Cube and this has fully solved the problem even in the highest gales. On the day I fitted the Flue cube the Aga was smoking bad but immediatly the Fluecube was fitted all smoke and smell ceased.
This has been a terrific investment and a reduction in fuel use is quite measurable.
Thank you for finally solving my problem.
