Trangia Cooking Stove Buying Guide 2026: 25 vs 27 vs Mini, Spirit vs Gas

A Trangia cooking stove buys you something most modern backpacking stoves deliberately don’t: the ability to actually cook. Rice, pasta, a fry-up, a stew left to simmer, in wind and rain, on fuel you can pick up from a Halfords on the drive to the trailhead. The design has barely shifted since the 25-series entered production in Ödeshög, Sweden in 1925 — Trangia’s own history page, trangia.se/about, dates it — because the nested aluminium windshield and the maintenance-free spirit burner solve a problem that faster stoves simply ignore.

This guide is compiled from Trangia’s published specifications (trangia.se product and spec pages), UK retailer listings, and owner consensus from Reddit’s r/ultralight and the UKHillwalking forum. No testing is claimed anywhere in it. What follows is which of the current models suits which trip, what the suffix codes on each box actually mean, and the arithmetic behind spirit versus gas running costs — the number most buyers never work out until they’ve owned the stove for a season.

Quick picks

If you want the short answer: buy the 27-2 UL unless you regularly cook for more than two people, in which case buy the 25-2 UL.

Why the Trangia cooking stove still makes sense in 2026

Almost every stove on the market is competing to boil water faster. The Trangia isn’t. It’s competing to let you cook a real meal using fuel that is cheap, widely stocked and carries no pressure.

Trangia’s own product guidance makes the case plainly. The spirit burner needs no cleaning and no maintenance, has no parts that can break, and runs quietly — because there is nothing to pump and no jet to clog. There is no valve to seize, no O-ring to perish, no piezoelectric igniter to fail. A metal cup, a fuel, and a flame.

Trangia is equally honest about the trade-offs. The company lists slightly longer cooking times, reduced output in cold weather, and fuel that “can soot depending on quality”. Anyone who tells you a spirit Trangia is as quick as a canister stove is selling you something.

That combination — slow, silent, unbreakable, cheap to run — is why the Trangia remains the default for Duke of Edinburgh’s Award expeditions, Scout groups and long-distance walkers, and why it can feel heavy in the hand next to a modern canister stove. This is a cooking system, not a water boiler, and you should buy it knowing the difference. If you want the fastest possible litre of hot water, a canister stove wins. If you want dinner, the Trangia is still the more capable tool.

How the Trangia system works

The windshield does the work

The Trangia’s real invention isn’t the burner — it’s the nested windshield. A lower aluminium half holds the burner; an upper aluminium half carries the pan supports and shields the flame from every direction. Because the flame is enclosed, wind has almost nothing to bite on, which is why a Trangia keeps working in conditions that blow out an open canister burner.

Pots and the frying pan then nest inside the whole assembly, and the frying pan doubles as the lid. The complete unit effectively becomes its own container, which is why a two-person Trangia packs down to roughly the size of a large lunchbox. Nothing here is clever in a marketing sense. It’s simply very hard to break.

Two burners, one stove

The choice of burner matters more than any other decision you’ll make, and Trangia’s own guide sets it out clearly.

The spirit burner runs on alcohol-based fuel — methylated spirit or bioethanol. Trangia lists the advantages as no cleaning, no maintenance, no breakable parts, quiet operation and easy use, plus the fact that it is the climate-friendlier option of the two. Against that: longer cooking times, reduced output in cold weather, and fuel that can soot depending on its quality. Trangia also instructs users to let the burner cool before refilling it, and warns about spillage — alcohol flames are near-invisible in daylight, so a spill you can’t see is a spill you can’t react to.

The gas burner is fast, easily adjustable, keeps pans soot-free, and uses an international standard connection for canister fuel. Fuel is easy to find and soot is minimal — but it burns a fossil fuel, and canisters cost more per meal than a bottle of methylated spirit.

The critical compatibility detail: both burners sit in exactly the same place in the lower windshield half. You are not buying a different stove when you choose gas; you are buying a different burner for the same chassis. That is what makes the GB suffix a genuine option rather than a fork in the road.

The simmer ring and the snuffer lid

The simmer ring — Trangia’s official name for it, used in the manufacturer’s instructions — slides over the burner to reduce the flame. This is the mechanism that makes actual cooking possible rather than just boiling: choke the flame down and you can hold a pot at a gentle bubble instead of a rolling one, which is the difference between pasta that cooks and pasta that welds itself to the base. It is included with every complete stove set, and sold separately for roughly £5 if you lose one.

The snuffer lid extinguishes the flame. Trangia’s instructions are specific on two points: do not blow the flame out, and do not refill the burner while it is hot. Both rules exist for the same reason — alcohol vapour ignites readily, and a burner you think is out may not be.

Fuel shopping in the UK

Methylated spirit is one of the great practical advantages of this stove in Britain. It is reliably stocked at Halfords (nationwide), Toolstation and Screwfix, typically at around £3–£4 per litre. Bioethanol is the cleaner-burning alcohol alternative and is stocked by outdoor retailers, though it costs slightly more.

The variant decoder: what UL, Duossal, -1, -2, -3 and GB actually mean

Trangia’s naming is unforgiving if you don’t know the code, and buying the wrong suffix is the most common mistake in this category. Every model number is a set of instructions:

UL means the pans are hard-anodised aluminium. Anodising hardens the surface of the aluminium, which makes it far more resistant to the scratches that metal spoons and pack abrasion inflict — and it does so at a fraction of the weight of steel. Duossal takes the opposite approach to the cooking surface: a stainless-steel base bonded to aluminium sides, so the part your spoon scrapes is steel while the walls stay light. Choose UL for weight, Duossal if you cook hard and often and want the base to take punishment.

-1 versus -2 is simply whether a kettle is in the box. -3 swaps the standard frying pan for a non-stick one, which matters if you fry eggs rather than boil water. GB means Trangia has put a gas burner in the box rather than the spirit burner — the stove body, windshield and pans are the same.

How to choose a Trangia

Work through four questions in order.

First, size. The 25 is the large model, built around 220 mm pans and aimed at three to four people; the 27 is the small one, for one to two people. This is the decision that affects everything else — a 27 is genuinely compact, but you will not be feeding four people from it comfortably.

Second, burner. Spirit if you want the lowest running costs, silent operation, no maintenance and fuel you can buy at a motorist’s shop; gas if you want speed, precise adjustment and soot-free pans. If you’re genuinely torn, a GB model plus a separately purchased spirit burner (typically around £30–£40 for the gas upgrade, around £20–£25 for a standalone spirit burner from Trangia direct or Cotswold Outdoor) gives you both burners for the same chassis.

Third, kettle or not. The kettle is convenient for a brew without dirtying a pan, and unnecessary if you already carry a lightweight kettle or only boil in pans.

Fourth, pan material. UL for light, Duossal for hard-wearing, -3 for non-stick.

Verify every weight figure against Trangia’s own spec chart on trangia.se rather than retailer pages — listings in the UK frequently quote shipping weights or omit the burner, and the discrepancy between two “official” weights for the same stove is one of the most common sources of confusion in forum threads.

Running costs: spirit versus gas, with the arithmetic

This is the part of Trangia ownership that rarely gets explained, and it’s where the spirit burner quietly wins.

The numbers behind that table: Trangia’s burner spec page rates the spirit burner at approximately 700 W output. Third-party burn testing and owner measurements circulating on r/ultralight put approximate spirit consumption at around 17 ml per 10 minutes at full output — treat that as an approximate figure rather than a laboratory constant, because it varies with the fuel and the conditions. At around £3–£4 per litre, 17 ml of methylated spirit costs roughly 5–7p.

Presented the same way, spirit works out at roughly 0.4–0.5p per gram of fuel consumed, against roughly 2–3p per gram for canister gas. The gap is large and it compounds over a season of weekends. What the table cannot tell you is cost per meal, because that depends on how long you cook — and Trangia publishes no boil-time or gas-consumption figures, so any precise “cost per boil” you see quoted elsewhere is somebody’s estimate, not a manufacturer guarantee.

Fuel weight: the multi-day trade-off

Running cost is only half the calculation. The other half is what the fuel weighs in your pack, and here the comparison flips depending on trip length.

Methylated spirit has a density of approximately 0.79 kg per litre, so 500 ml of fuel weighs about 395 g. A 230 g gas canister contains 230 g of gas but its steel body adds roughly 100 g, so the canister as carried weighs about 330 g in total.

Compare like with like. On a short trip, the canister’s convenience is nearly free: 330 g of gas against 395 g of spirit, and the canister is faster. But you cannot half-fill a canister to match a two-day trip, and you cannot top one up from a bottle. Spirit is decanted to exactly what you need — 200 ml, 300 ml, whatever the itinerary demands — and the bottle can be refilled for the next trip.

That is why for trips longer than about three days, the spirit system’s total weight typically becomes competitive. The canister stove carries a fixed penalty of roughly 100 g of steel per canister, and if you need more than one canister for a long outing, you pay it more than once. The spirit bottle is re-usable and its weight is fuel plus a thin container. Do the arithmetic for your own trip length before assuming gas is the lighter answer, because below three days it usually is and above it often isn’t.

Cold weather: an honest limit

Neither burner is a winter mountaineering solution, and Trangia doesn’t pretend otherwise.

Spirit burner output drops noticeably below roughly 5 °C. Trangia publishes no exact threshold figure for this — the company’s guidance acknowledges that output becomes difficult in cold degrees, but no precise temperature is stated, and we’re not going to invent one. Plan for a meaningful drop in performance in anything approaching freezing.

Gas has its own problem. Standard butane/propane mixes degrade below 0 °C, because the pressure inside the canister falls away and the burner starves. Isobutane canisters — the type sold by Primus and MSR — perform better in the cold than plain butane, but they still degrade as temperatures fall. A canister you can warm in your jacket will keep going longer than a cold one, but that is management, not a fix.

The honest conclusion for UK buyers: a Trangia is a superb three-season cooking system and a compromise in deep winter, whichever burner you fit.

The models reviewed

Trangia 27-2 UL

Best for: the majority of buyers — one or two people on three-season trips.

The 27 is the small Trangia, and the -2 UL is the configuration most people should buy. You get the complete system: the lower windshield half that holds the burner, the upper windshield half with its pan supports, the spirit burner, the frying pan that doubles as the lid, the simmer ring and the snuffer lid — and no kettle, which keeps the box (and the price) down. The pans are hard-anodised aluminium, so they shrug off spoon scrapes while staying light. Because the whole assembly nests, it packs to roughly the size of a large lunchbox and carries itself.

The standout strength is that combination of completeness and indestructibility. There is no maintenance schedule, no cleaning routine, no jet to clear, and nothing that fails on a cold morning. The honest caveat is speed and cold-weather output: at approximately 700 W the burner is not fast, and output drops noticeably below around 5 °C. Pack accordingly.

Verdict: the default Trangia, and the right first stove for most people.

Where to buy: typically stocked by Cotswold Outdoor and Ellis Brigham at around £70–£80.

Trangia 27-1 UL

Best for: solo or duo cooks who want a brew without dirtying a pan.

The 27-1 UL is the identical 27-size UL system with one addition: a kettle. Everything else — the two windshield halves, spirit burner, pan supports, frying pan/lid, simmer ring and snuffer lid — is the same, so it cooks exactly like the 27-2 UL and suffers exactly the same cold-weather limitation.

For some buyers the kettle is the difference between a good trip and a great one: you can have coffee while the porridge pan stays clean, and you avoid rinsing a pan just to make a hot drink. For others it is dead weight and one more thing to nest around. That’s the entire decision.

Verdict: buy it if a morning brew matters to you; otherwise the kettle-less 27-2 UL is the leaner choice.

Where to buy: look for it alongside the 27-2 UL at Cotswold Outdoor and Ellis Brigham. Trangia does not set UK shop prices itself, so check current listings rather than assuming a fixed figure.

Trangia 27-2 UL GB

Best for: anyone who wants speed and adjustability, or who camps where spirit is hard to buy.

The GB suffix means Trangia has supplied the gas burner instead of the spirit burner. Everything else in the box is the 27-2 UL package. Because both burners sit in exactly the same place in the lower windshield half, this is a bolt-in substitution, not a different stove: the windshield, pan supports, pans and frying pan/lid all remain.

The standout strength is controllability. Gas is fast, adjusts instantly from a roar to a whisper, keeps pans soot-free, and uses an international standard canister connection — so canisters are easy to find. The caveats are real too: canister gas is a fossil fuel, costs more per gram than methylated spirit, and standard butane/propane mixes degrade below 0 °C. It’s also worth noting the trading position — a GB set costs more than the spirit version, and you’re paying for the burner rather than the chassis.

Verdict: the right call for impatient cooks and cold mornings; the wrong call if running cost and silence are your priorities.

Where to buy: stocked by the same UK outdoor retailers as the spirit models. Expect a premium over the spirit equivalent, and check Cotswold Outdoor and Ellis Brigham listings for the current figure.

Trangia 25-2 UL

Best for: families, groups of three to four, and anyone cooking proper meals in volume.

The 25 is the large Trangia, built around 220 mm pans with genuine capacity for three to four people. The -2 UL is the kettle-less configuration in hard-anodised aluminium, and everything about the system is the same as the 27 — lower windshield half holding the burner, upper half with pan supports, frying pan as lid, simmer ring, snuffer lid — just scaled up.

The strength is that it stops being a compromise. Cooking for four out of a 27 means boiling in batches and eating in shifts; cooking for four out of a 25 means one pot of pasta and one pan of sauce, both at once, in the wind. The caveat is bulk and weight: the 25 is a larger package in your pack, and it is not the stove you buy for solo weekends. Verify the packed weight against Trangia’s own spec chart on trangia.se rather than trusting a retailer listing, which often quotes a shipping figure.

Verdict: the group stove — buy it if you routinely feed three or more.

Where to buy: typically around £85–£95 from Cotswold Outdoor and Ellis Brigham.

Trangia 25-1 UL

Best for: groups that want hot drinks on demand without a second pot.

The 25-1 UL is the 25-size UL system with a kettle added — the large pans, the spirit burner, the two windshield halves, pan supports, frying pan/lid, simmer ring and snuffer lid, plus the kettle for brews and for topping up dehydrated meals.

For a group, the kettle argument is stronger than it is for a solo walker: four people wanting tea without stewing the dinner pan is a genuine logistical problem, and a kettle solves it in one move. The trade-off is the same as on the 27 — an extra item to nest and an extra item to carry.

Verdict: a sensible upgrade for groups; optional for pairs.

Where to buy: alongside the 25-2 UL at Cotswold Outdoor and Ellis Brigham. Check current listings for pricing, since Trangia’s UK prices are set by the retailer rather than published centrally.

Trangia 25-2 UL GB

Best for: larger groups who want speed, or who want to cook on gas at scale.

This is the 25-size UL package — 220 mm pans, no kettle — with the gas burner in place of the spirit burner. The chassis, windshield, pan supports and frying pan/lid are unchanged; the burner simply drops into the same seat in the lower half.

For a group, gas makes a particularly strong case. When you’re boiling two litres of water for pasta and then simmering a sauce, a burner you can turn down precisely and that responds instantly is worth real time, and soot-free pans matter more when there are more of them to wash. The counterweight is cost: canister gas works out at roughly 2–3p per gram against roughly 0.4–0.5p per gram for methylated spirit, which adds up quickly when you’re boiling large volumes. Add that butane/propane mixes degrade below 0 °C.

Verdict: the group go-anywhere option for three-season trips; the spirit version remains the value choice for cost-conscious groups.

Where to buy: the usual UK outdoor retailers, priced above the spirit 25-2 UL. Check Cotswold Outdoor and Ellis Brigham listings for the current figure.

Trangia Mini 28-T

Best for: solo walkers, bikepackers and anyone counting grams.

The Mini 28-T is the small, self-contained end of the range: a compact single-person unit that Trangia’s own published chart lists at 350 g and which packs to Ø150 × 67 mm. That is small enough to disappear into a rucksack side pocket — roughly the footprint of a large tin — and light enough that it stops being the reason you left the stove at home.

The strength is that it delivers the two things the Trangia name promises in the smallest possible package: a wind-shielded flame and a simmer ring, so you can actually reduce the heat rather than merely boil. The caveat is capacity — this is a one-person pot, so it is not the stove for a shared meal, and it gives up the nesting frying pan and multi-pan flexibility of the 27 system. It’s a boiling and simple-cooking tool rather than a kitchen.

Verdict: the right Trangia for a solo ultralight kit; the wrong one if you ever cook for two.

Where to buy: typically around £35–£45 from UK outdoor retailers, the same shops that stock the 25 and 27 sets.

What the Trangia isn’t: two rival benchmarks

It’s worth being clear about the competition, because the Trangia’s weaknesses are other stoves’ strengths.

Jetboil Flash

Jetboil’s Flash is the archetypal integrated canister system, and jetboil.com states a manufacturer system weight of 371 g. That figure is in the same territory as a small Trangia — the difference isn’t weight, it’s purpose and fuel. The Flash is built to boil water fast in an integrated pot; the Trangia is built to hold a simmer in the wind. Note also that canister fuel is additional on any canister stove, so the honest comparison adds a 230 g canister (roughly 330 g as carried, including steel) to the Flash’s side of the scales.

MSR PocketRocket Deluxe

The PocketRocket Deluxe is at the opposite extreme: msrgear.com lists it at 73 g for the stove alone. Nothing in the Trangia range competes with that bare weight, and nothing in the MSR’s design shields a flame or holds a simmer the way the Trangia’s windshield and simmer ring do. Again, add fuel separately — a 230 g canister brings the Deluxe to roughly 400 g as carried. That’s the genuine trade: an ultra-light open burner that you shelter with your body, against a heavier enclosed system that shelters itself.

UK practicalities: fuel, travel and group kit rules

Fuel availability. Methylated spirit is the reason this stove works so well in Britain. It is reliably stocked at Halfords nationwide, plus Toolstation and Screwfix, typically at around £3–£4 per litre. Bioethanol, the cleaner-burning alternative, is stocked by outdoor retailers at a slightly higher price. You are never far from fuel.

Air travel. Methylated spirit cannot be carried on aircraft. State that plainly to yourself before you plan a trip: you fly, you buy fuel at the other end, or you use a gas burner with a canister sourced locally. Don’t turn up at security with a fuel bottle.

Group and award schemes. The Trangia’s reputation in youth expedition work is long-standing. If you’re buying for a Duke of Edinburgh’s Award expedition, check the current kit guidance on dofe.org directly — their equipment list is the authoritative document and it changes. The Scout Association publishes its own kit policy along similar lines. Both are worth reading before you buy, because a group’s rules can override your personal preference on burner type.

Where to buy in person. Cotswold Outdoor and Ellis Brigham are the two primary bricks-and-mortar retailers stocking Trangia in the UK, which matters if you want to handle the nesting assembly before committing — the physical size difference between a 25 and a 27 is much more obvious in the hand than in a spec table.

FAQ

Can I use a gas burner and a spirit burner in the same Trangia? Yes. Both burners sit in exactly the same place in the lower windshield half, which is what the GB suffix is really telling you — it’s a burner substitution, not a different stove. A separately purchased spirit burner typically costs around £20–£25 from Trangia direct or Cotswold Outdoor, and a gas burner upgrade is typically around £30–£40, so owning both for one chassis is straightforward.

Can I take a Trangia cooking stove on a plane? The stove itself travels fine as hold luggage, but the fuel does not: methylated spirit cannot be carried on aircraft at all, full stop. The practical approach is to fly with an empty, thoroughly aired burner and buy spirit or a canister at your destination — which is easier in the UK than almost anywhere, given how widely Halfords, Toolstation and Screwfix stock the fuel.

Is a Trangia suitable for Duke of Edinburgh’s Award expeditions? The Trangia has been the archetypal DofE stove for decades, but don’t take our word for it — check the current equipment list on dofe.org, which is the authoritative source and is updated periodically. The Scout Association publishes a similar kit policy. Both can specify burner type, and a group’s rules take priority over individual preference, so read the guidance before spending.

Do I need the kettle version, the -1 model? The -1 suffix means a kettle is in the box; -2 means it isn’t. A kettle lets you make hot drinks without dirtying a pan, which matters more for groups than for solo walkers, and it costs you an extra item to nest and carry. If you already carry a lightweight kettle, buy the -2.

How much does it cost to run a Trangia — spirit or gas? Methylated spirit at around £3–£4 per litre (Halfords, Toolstation) works out at roughly 5–7p per 10 minutes of full-output burning, based on approximate consumption of 17 ml per 10 minutes. Canister gas, at around £5–£7 for a 230 g Primus or MSR canister, works out at roughly 2–3p per gram of fuel — several times dearer per gram than spirit. Trangia publishes no gas consumption rate, so there is no manufacturer cost-per-boil figure for either fuel.

Will a Trangia work below freezing? Only with caveats. Spirit burner output drops noticeably below roughly 5 °C, and Trangia publishes no exact threshold — the company simply acknowledges reduced effectiveness in cold degrees. Gas burners using standard butane/propane mixes degrade below 0 °C, and even isobutane canisters from Primus and MSR lose performance as it gets colder. Neither is a winter mountaineering solution.

What’s the difference between UL and Duossal pans? UL means hard-anodised aluminium, where the surface treatment hardens the metal so it resists scratching while staying light. Duossal uses a stainless-steel base bonded to aluminium sides — steel where your spoon scrapes, aluminium for the walls. Choose UL for weight, Duossal if you want the cooking surface to take years of abuse.
