Clip-together insulated flue pipe is generally referred to as "twin wall". It is two skins of metal with about an inch of insulation (Rockwool usually) sandwiched in between. Twin wall pipe generally gets no hotter than a radiator and can be as close as 5cm to combustible materials without any fire risk. So when we refer to "twin wall" pipe, this is what we mean. Single skin vitreous pipe is metal flue pipe 1-2mm thick. This gets very hot indeed and can set fire to combustible materials if they get too close.
Because twin wall pipe has clip-on locking bands a chimney made only of twin wall (without vitreous pipe at all) is very strong structurally. Hence only one bracket is required. We often get asked if we can use vitreous pipe instead of the insulated twin wall for the first metre above the stove. We can. BUT the joint is weak (wobbly) and this can only be rectified by having two twin wall brackets instead of one. Also single skin vitreous pipe must be kept at least 15-18" away from any combustible materials. Let us know if this is a customisation you wish to make.
5" twin wall has a outer diameter of 192mm and 6" has a diameter of 217mm. Your hole diameter in the roof will be 300mm for 5" twin wall and 325mm for 6" twin wall. Add another 4cm to this hole size if passing through a boxed-in area (where heat might build up).
Because it is insulated the clip-together insulated flue pipe can be as close as 5cm to wood and is completely safe (7cm if the flue is boxed in). It typically gets no hotter than a radiator. For more info on combustible materials and hearths etc. see further down in this article.
NOTE: If fitting an Ekol Applepie stove, with their Applepie bespoke rear adaptor, we will need to add a sweep door to the lowest section. See "Customer's Also Bought".
Super easy to install - the chimney parts just clip together and the bottom of the chimney just inserts into the stove with a wrap of sticky-back fireproof stove pipe webbing (supplied). Ever heard of Meccano kits ? You get the picture.
If your stove has a 6" collar then choose a 6" connection and 6" flue.
If your stove has a 5" collar then choose a 5" connection and 6" flue.
If your stove collar is 5" AND your stove is DEFRA Smoke Exempt (DEFRA-approved) then you can also choose a 5" connection and 5" flue (looks less fat).
If your stove has a 4" collar then choose a 4" connection and 5" flue"
If your stove has a 4" collar AND is NOT DEFRA Smoke Exempt (DEFRA-approved) then choose a 4" connection and 6" flue.
Here we show the standard contents of a shed kit. The different lengths can be assembled in any order and no glue or sealants are required. We supply 2x 500 lengths in stead of a metre so lengths can be moved around to prevent a conflict between a joint and a bracket or roof flashing.
You can make changes to the kit if you require. See "Customers Also Bought" for "Shed Kit Customise". If you have a tiled roof (rather than a felt, metal or glass fibre roof) you will want to change the roof flashing shown for a aluminium or lead flashing. If you do not want the supplied wall bracket you chan change it for a roof/rafter support that can attached to rafters and sometimes even completely hidden.
Please take a look at the product "Shed Kit Customise" before ordering in case you spot something important.
Note that the roof flashing is not corrugated by default as in the picture. The silver flange is pliable and can be moulded to the shape of the roof and retains the shape you create.
This image shows a roof/rafter support that can be chosen to replace the usually-supplied wall bracket. See "Customers Also Bought" for "Shed Kit Customise".
Note that the graphic creators forget to put down a hearth ;-)
In this kit: 1x stove to twin wall adaptor, 2x 1000mm twin wall straights, 2x 500mm twin wall straights, 1x twin wall weathering cowl, 1x roof flashing EDPM ezi-seal, 1x ceiling finishing plate, 1x adjustable bracket 130-210mm, 5x narrow joint clamp (connects parts together), 1x fireproof webbing (for adding to snout of twin wall where enters stove). Some of the included items can be changed or upgraded (see Customers Also Bought: ALL SHED KIT OPTIONS).
The two flashings we sell are easy to install and leakage is zero when installed properly. Hole size should be diameter of pipe plus 50mm air gap all round for safety (70mm all round if pipe boxed in and not open to the air). So that's 100mm extra on the diameter or 140mm extra on the diameter if passing through a boxed in area. 5" twin wall has a outer diameter of 192mm and 6" has a diameter of 217mm. You can fill the air gap with Rockwool afterwards or just leave as "air".
Note that the roof flashing is not corrugated by default as in the picture. The silver flange is pliable and can be moulded to the shape of the roof (flat or corrugated) and retains the shape you create. This flashing comes with the shed kit as standard.
This is an EDPM flashing and is suitable for almost all non-tiled roofs (felt, glass fibre, rubber, EDPM, zinc, etc.) and will even work with corrugated roofs. Metal roofing screws (or wood screws into wood) are used. Screws are not supplied in our kit.
If screwing into felt/wood use wood screws. If screwing into a metal roof use roofing screws (Google metal roofing screws with rubber washers).
No Silicon required as this part has a flange that compresses when screwed down although some installers add a bead of Silicon anyway.
EDPM flashings are perfectly water tight.
If is possible to not use screws and just use Silicon. In this situation you would create a wood "pattern" to apply weight to the flange of the flashing whilst the silicon cures. Please request from us a different EDPM flashing for this purpose (NOT the Ezi-seal). Seach "conservatory" in the search button of this site for our "stove in a conservatory" article as this mentions a customer who added his EDPM flashing to glass with no screws or bolts.
This is an aluminium/rubber flashing suitable for tiled surfaces e.g. Slate roofs etc.). See "Customers Also Bought" for "Shed Kit Customise" to make sure your kit comes with this option - otherwise you will receive the Ezi seal EDPM.
It is perfectly feasible to DIY such a task although some may find it easier to get a roofer to complete this part of your stove install.
It is also possible, in our "Shed Kit Customise" product, to choose a lead/rubber flashing. This is considered by roofers to be superior to the aluminium version. It is though expensive and may be considered and unnecessary.
This twin wall adaptor is supplied with the kit and is the lowest part in the system and connects to the stove. The snout of this part can be cut shorter so it is all hidden within the stove collar. Wrap fireproof webbing (included with the shed kit) around the snout before sliding the snout snugly into the stove, No fire cement then required.
This part can slip into the female end of a length of vitreous (NOT the tapered end) OR directly into a stove if going "twin wall all the way".

NOTE: If fitting an Ekol Applepie stove, with their bespoke rear adaptor, we will need to add a sweep door to the lowest section. See "Customer's Also Bought".
This kit assumes you have a roof overhang of no more than 8.5cm. If your overhang is between 8.5cm and 15cm let us know the overhang dimension in the NOTES section of checkout (we can upgrade you to longer brackets at no extra cost). If overhang longer than 15cm you will require a bespoke twin wall chimney design.
With this same kit you can juggle the lengths around as required and therefore create three different configurations with this one kit: 2A, 2B or 2C and this should be the same whether your roof is flat or sloping. The simple diagrams below are for a 2.3m wall height with a 50cm high stove. The taller the first pipe placed on the stove, the better the performance so 2B or 2C are preferred (but do not over-worry this).
If your stove has a 6" collar then choose a 6" connection and 6" flue.
If your stove has a 5" collar then choose a 5" connection and 6" flue.
If your stove collar is 5" AND your stove is DEFRA Smoke Exempt (DEFRA-approved) then you can also choose a 5" connection and 5" flue (looks less fat).
If your stove has a 4" collar then choose a 4" connection and 5" flue"
If your stove has a 4" collar AND is NOT DEFRA Smoke Exempt (DEFRA-approved) then choose a 4" connection and 6" flue.

In this kit: 1x stove to twin wall adaptor, 1x 1000mm straights, 2x 500mm straights, 1x 250mm straight, 2x 45 degree elbows, 1x weathering cowl, 2x 45-degree finishing plates, 1x adjustable straight length for thru wall 380-585mm, 8x narrow joint clamp (connects parts together), 2x brackets 95-135mm, 2x 45 degree oval finishing plates, 1 metre fireproof webbing. Some of the included items can be changed or upgraded (see Customers Also Bought: ALL SHED KIT OPTIONS).
It is easy peasy - honestly. The two sealing plates we supply are easy to install and leakage is zero when installed properly. They are ideally applied to a flat surface with silicon sealant. Hole size will be an elipse (egg shape) and you can draw around the inside of the flashing to get you hole shape. But then you will need to make that elipse larger: plus 50mm air gap all round for safety (70mm all round if pipe is boxed in and not open to the air). So that's 100mm extra on the eclipse diameter or 140mm extra on the eclipse diameter if passing through a boxed in area. You can fill the air gap with Rockwool afterwards.
This twin wall adaptor is supplied with the kit and is the lowest part in the system and connects to the stove. The snout of this part can be cut shorter so it is all hidden within the stove collar.

See "CUSTOMISE SHED KIT" in "Customers Also Bought". Below are just a few of the options available - why not take a look?
If you do not wish to see a bracket in the shed or garage (or have no wall within reach) you can choose instead to fit a roof/rafter support that fits in the roof space or directly on the ceiling.
Note that this part may need "hiding" in the void of the roofspace or may be "on show" on a ceiling. You can box it in of course, as long as you ensure all distance to combustibles regulations are followed (7cm minimum air gap between twin wall and combustible material).
Distance to combustibles article
To add this bracket instead of the visible bracket please see "CUSTOMISE SHED KIT" in "Customers Also Bought".
You might wish to replace the bottom length of twin wall with a "removable" section so the stove can be removed as desired without dismantling the chimney. Building regs does state that a stove should be removable without dismantling a chimney so this can be wise. Our thoughts with such a short chimney are that the chimney is so easy to dismantle anyway this point is rather moot. Note also that Building Regulations are usually not relevant for properties not connected to a main dwelling and classed as non-habitable (don't take our word for it for every situation).
If you do choose to opt for this part it has its own built in adaptor to connect to the stove.
More about this part here including detailed images of the exploded part.
To add this part instead of a standard 500mm length please see please see "CUSTOMISE SHED KIT" in "Customers Also Bought".
Need to add any extra lengths? You can choose your items here. Do not forget that every extra length requires a narrow locking band as these are not included by default.
You can have up to 1.8 metres of unsupported flue (so 1.8 metres above the highest bracket or roof support). If more than 1.5 metres unsupported (but less than 2 metres) please add a "wide locking band" to the first joint above the highest bracket /roof support. Wide locking bands go around narrow locking bands (so both needed on same joint).
If like many people, your shed or garage is your refuge, then you want to make it as comfortable as possible. This means finding a way to keep it heated during the colder months.
A small wood burning stove is the perfect solution. It can completely transform a cold and unwelcoming shed or garage into a warm and cosy retreat.
Installation is probably a lot easier than you might think. With sheds, garages and garden rooms not attached to the main property no permissions or certificates are usually required. DIY wood stove install is not a difficult task as the chimney system is "clip-together" and because it is a shed we are not working at a great height.
For most small spaces, a small 4-5kW logburner is probably the right choice. You can use a calculator to check what heat output would be best (you can find out what size wood stove for your room here). This is based on the space inside your shed. However, unless you have a huge shed or garage, a 4kW or small 5kW stove is probably the right size for you. While small, it will produce a lovely cosy fire and plenty of heat. Or choose a smaller 5kW stove and put less wood in it!
Some stoves have integrated log storage which can be handy, as it will save you from going out in the cold when your stove needs topping up with combustibles.
Ultimately, it is a matter of preference. The best stove is one that fits in the space, and that you like the design of. Check out the small stoves on this page or view all of our wood burning stoves.
If you can, it is best to make sure that the flue of the stove will be more than 2.3m in length from the outer wall of your home. Flues closer than this have to be taller than your home. If it's beyond this distance, it only has to be 1m above the top of your shed's roofline.
For best results a minimum 3m of chimney height above the stove is required (higher the chimney the better the draw). Inside the shed or garage, the stove should be no closer than specified in the stove manual to the nearest combustible material. See our article Distance to Combustibles.
The video here is only six minutes long and explains the basics of chimney design (minimum height, 2.3m rule, allowed number of bends etc.).
Easy peasy! Okay there's a few things to think about - but it is not rocket science.
Any vertical combustible surfaces near your stove or flue pipe should be protected with a heat shield if they are within the distances to combustibles set by the manufacturer (search the Internet to find the "installation instructions" for your stove. A heat shield is made of a non-combustible material (usually steel but Hardiebacker board also works) that will protect the walls of your shed. Heat shields are made from non-combustible materials, and they are fitted with a small air gap between the wall and the shield.
Depending on the location of your stove, and the layout of your shed or garage, you may need shields at both the back and side of the stove.
How to find out more and how to create a heat shield? See our article Distance to Combustibles.
The 4kW Saltfire Scout has a supplied rear heat-shield and this ensures a very low distance to combustibles at the rear of the stove of just (100mm) 4").
If in a shed or outbuilding then building regulations are not applicable (if not habitable). But you still want to be safe. Choose a stove that is allowed to sit safely on a 12mm hearth (see each of our stove pages for this information as stoves are clearly labelled as "12mm hearth". Then find a slab for the stove to sit on (your new hearth). Builder's merchants outdoor-yards are perfect for this: slate, sandstone, concrete, granite are all fine examples. Just make sure it is 12mm thick minimum ideally 25mm+. Size should be bigger than the stove by 15cm all the way around but allow 30cm in front of the stove glass (in case a red-hot ember drops out). Note that Building Regs say hearth should me min 84cm x 84cm so if in a "habitable property" that is what you would do).
