BUILDING REGULATION COMPLIANT—includes sweep access, ability to remove stove without dismantling chimney, wall-lined with sleeve and no 'connection between parts' in wall. All building regulation requirements often ignored by other sellers.

Creating a clip together chimney for a wood burning stove is not difficult but there are quite a few possible "design scenarios" for different building types. But going out through a wall is almost always the same for everybody. The idea of our "easy peasy" kits is to start you off with the key parts. You just add straights to gain height, a bracket or two and a cowl (from the "you may also need" section on this page).

We strongly recommend you watch the six minute video on this page that explains Chimney design rules and regulations.

Black is the silver powder coated on top of surface. Twin wall is stainless steel professional Silvacore PRO manufactured by Duraflue. We have chosen this as it does not rust, fade or yellow. Julian, author of the Stovefitter's Manual, has a Silvacore PRO twin wall chimney on his own home (since 2014).

More information on  chimney design on our quick links page.
More information on self-installing in a habitable property

Note: Best performance is realised by attaching a flue to the top, rather than the rear of the stove. This is because smoke likes to rise. 

 

"Easy peasy chimney design"

Julian Patrick, site owner and author of The Stovefitter's Manual.

This kit includes a superbly designed part called the 135 degree T with prolonged adjustable snout. The long snout extends or retracts like a trombone so you can adapt it to the wall thickness. It also allows you to sweep most of your chimney outside the property.

You might ask "Can I not just have an elbow on the outside of the building—instead of this more expensive part?". The answer is yes, you can use an elbow instead (see a different kit)—but only if your complete flue only requires two changes of direction. For example, on a gable end with no roof overhang you do not need further bends than the one inside the house and the one outside. But if you wish to add two more bends (max. is 4 in total), then you have to have the 135 degree T with its "building regulation legal" soot/sweep access door.

To keep it simple—if you desire to use four bends then you need this part with its soot door (theb 135 T counts as two of the four bend limit and allows you to add two more). Just two bends in total and you can save some money by replacing it with a straight length through the wall and an elbow. 

We recommend you watch the video (below) on chimney design.

Excellent Customer Service, Thoroughly Recommended. (Order no: 20764)

Having spent most of the previous year researching a small stove for our garden log cabin it was such a relief to find Stovefitters Warehouse, just wish I found them a lot sooner. Their website is easy to navigate and they have a wealth of information and videos available. We had previously been quoted rediculous prices to install a stove but after studying Stovefitters info we decided to do this ourselves. Communication was very efficient, by text and phone calls, and all our queries and questions were answered. So good to have 'real people' to contact. We orderred the Salamander Hobbit stove and the shed fitting kit. The stove is awesome and kicks out a lot of heat for its size, we returned a couple of items from the fitting kit and orderred others, all straight forward and simple. We have recommended Stovefitters to several friends already and will continue to do so. Would definitely use them again, excellent company to deal with.

Twin wall for extension

I would Recommend Stovefitters warehouse, overall very straightforward process, Ray is friendly and the design system works well. Also worth mentioning that he was right and I was wrong when I thought lower height would be Ok so I do now have almost 2m out of a pitched roof near main house. My only gripe is that I should have had a final xtra wide locking band on the last join (I have one on the first ext joint) I’ll find out how strong it is when the storm hits this pm. very good quality this Duraflue

Brilliant Customer Service

Ordered on Monday, delivered by day of our choosing which was Thursday of same week. Absolutely Brill Service. When unpacking we noticed an item missing (genuine mistake) and on contacting company missing part was delivered next day. Couldn’t fault service at all. We also contacted company a number of weeks later with a query which was promptly answered with information and links to appropriate websites. 😀

New woodburner in single storey Somerset barn, ref 18258

With the cold snap, I realised that the electric underfloor heating was getting expensive. Having a wood burner in the main house, I thought a small wood burner in the front barn would be an added attraction as well as a cost saving.
I initially approached a local installer who quoted for the installation of flue but not the stove. The total costs were sufficiently daunting for me that I looked around the internet and arrived at the Stovefitters site, They seemed to supply all the information required and I was not daunted to take on the task of a DIY installation. I was very impressed by the prompt delivery of Fire and flue and the return of a bracket was very simple and straight forward wirth a local branch of Dura Flue.
I am very happy with the 5KW stove recommended and saved a considerable amount of money on initial quotes elsewhere. Thank you and Jackie for your help. Martin Dunsford

Saltire Peanut 5

My garden office was heated by oil filled electric radiators. On the first of December we came off a fixed rate tariff which effectively doubled the cost of heating my office. I had been looking at woodburning stoves options for a couple of months and found the Stovefitter Warehouse website which provided me with everything I needed to undertake the fitting myself. I ordered the stove and flue pack which was delivered on time to the hour! So between Christmas and New Year I completed the fitting of the stove and am sitting in my warm office typing this review! I am so impressed with the service and products that I am looking at fitting a stove in our lounge to replace the open fireplace - but I will be getting a professional installer to do that one.

Excellent quality, amazing service

I had already ordered a stove from the wonderful folks at Stovefitters Warehouse (knowledgeable experts who are happy to share their knowledge) and took up the offer of the free design for the flue. I had various queries and these were always answered promptly and clearly. The quality of the materials is amazing, my stove is now fitted with its wonderful flue, the visuals on the roof of the outbuilding where it is installed are very appealing, and the stove draws beautifully with the smoke coming cleanly up and away from my flue. I am very happy indeed with the quality of the products, the amazing service, and the value for money. I would recommend the company without hesitation.

Hobbit Stove and Flue Kit

The stove was really simple to self install and the duraflue clip together kit made the whole process even easier. I installed this kit into a converted horse lorry and the size and Kw is spot on for the project. The Stovefitter's Warehouse website was really useful, with a heap of advice and guidance for fitting.
I needed to contact the company as I'd ordered a couple of parts I didn't need and they were really helpful, taking returns and sorting refund really quickly. Definitely use this company if you want a stress free purchase and decent advice.

Great flue kit for my cabin

Many thanks Stovefitters for the kit and general guide on your website. Delivery was quick and the kit is of high quality. I ordered an extra flue to get more height with the advice of additional belt. I also took on a do it yourself the ‘air shield’ suggestion as well, fitted mostly myself with some assistance from my son for a second pair of hands. Highly recommended and so far the heat is being contained my the flue/shield to protect the cabin wood. Highly recommended!

Twin wall external flue

Order number: 16210
I wanted to install my own wood burning stove and when I got I touch I was given so much great advice. Ray designed my twin wall external flue in accordance with the latest regulations and Julian provided me with excellent advice as to which stove brands to look at. Delivery was fast and arranged conveniently for when I could be at home. Then the after sales has been second to none. I have been in touch pestering the life out of them for advice and every question has been answered quickly and expertly. I cannot rate this company highly enough.
Thank you.

DIK GEURTS DG IVAR 8 (16215)

We have had our Ivar 8 stove fitted for just over a week.
We are very pleased with the product both aesthetically and build quality wise.
It is our first wood burner so it is difficult for us to gauge the Ivar 8 against any other brand ,what we can say is that it certainly exceeds our expectations.
It is very easy to use and a pleasure to sit in front off .
Our purchase was made so much easier by the very helpful advice given by Julian and Ray .
The web site is brilliantly put together and is a mine of information that puts the consumer very much at ease with the knowledge it provides.
We have been very pleased with Stove Fitters and although we did have some logistical problems, we understand that it is an exceptionally busy time in the industry. Julian did everything in his power to rectify any issues and has a fantastic customer service ethos.
We would highly recommend them as a first stop for all your wood burner needs

Would use again

Bought the shed kit, with some modifications. Overall, the information on the site was accurate and very useful, whether to do with design, regulations or choosing parts.

I found that the silicon flashing supplied with the shed kit was barely big enough after I’d allowed 70mm all around the 5” TwinWall Flue as it went through the shed roof. I wish I’d opted for the larger flashing, as if you are more than a couple of mm out in your positioning of the roof-hole, the edges of the standard flashing can’t be fixed to the roof. This could be made more prominent on the website.

At the end of the day the job was completed quickly and easily - I wouldn’t have dared attempt it if it weren’t for the excellent site.

Prices were excellent and delivery was very quick.
Another thing I liked was the owner or manager is always willing to give advice on the phone.

Complete Set of Log Cabin Flue Kit

Great packages for all things related to wood burning stoves and flue systems. With the procedures clearly laid out on Stovefitter Warehouse, I was able to order and install a wood burning stove in my log cabin.
Due to placing my wood burner further away from the walls, I needed a longer adjustable bracket. Julian helped immensely in sorting the challenge with prompt response to return of the short bracket and appropriate longer one.

All in all, I have bought excellent products here & received superb customer services. Will gladly use Stovefitter Warehouse again!

Shed kit fitted and cosy in a day

When i first started on the idea of fitting a log burner plus flue inti my summer house i was nervous to say the least.
The summer house was 4 grand and i didnt fancy reducing it to a pile of ash.
Then I found the Stove fitters website.
What a wealth of information and the best thing, Its all free!.
I gathered all the information I could and contacted the team at stovefitters for some final details.
What a great service. I ordered the shed kit and the team were straight on it, sorting delivery and in a couple if days it was here.
The quality of all the parts were exceptional. Built to last unlike some of the flues ive looked at.
Armed with my new knowledge we had the flue and stove fitted in a day and its now wonderful and cosy.
Its rare i recommend a company, but the team at stove fitters were A1 at their game. If I ever need anything else or more of that free information, they will be my first port of call.
Thank you.

Cabin/Shed twin wall chimney kit (easy peasy clip-together)

Having looked online at numerous sites for a twin wall chimney for my small wood burner in my cabin, the Stovefitter's Warehouse had not only what I was looking for at the best price, but also a wealth of help and advise on their site.

I used their guides to create a metal heat shield, hearth and also to install the twin wall chimney kit I purchased from them. The guidance online is really helpful and to say the installation is easy, is an understatement.
The overall service from Stovefitter’s Warehouse was excellent from start to finish and my 6’’ Twin Wall Wood burning stove in a shed chimney kit is perfect and looks superb in my cabin.
I wish I had looked at their site before purchasing my stove from another provider as they do some great deals when you buy both a stove and chimney from them.
You can buy from these guys with confidence.

Wood Burning Stove in a Shed Chimney Kit

Order # 13123 Described as 'easy peasy clip together' and that's exactly what it was! Great communications on the order meant that I was able to customise the kit to include the roof flashing and wall bracket that I needed. It came with everything that I needed to install my log burner into my log cabin and everything seems to be of excellent quality and looks great. I would highly recommend Stovefitter's Warehouse shed chimney kit to anyone looking for a similar installation.
