Why British hill conditions punish stoves

On a still, mild evening in a campsite, almost any stove will boil a pan of water. Take the same stove onto a Cairngorm plateau in February or a wet Lakeland col in a gusty October, and the differences show up fast. Three things do the damage: wind, which strips heat from the flame and the pot; cold, which saps the pressure out of gas cartridges and makes liquid fuels harder to light; and damp, which makes everything fiddly when your hands are numb and the light is going.

Add the practical reality of carrying fuel on your back, and the question stops being “which stove is best?” and becomes “which stove suits the trip I'm actually doing?” Here's how the main options behave in UK conditions.

Gas stoves: convenient, with cold-weather caveats

Gas is what most hillwalkers reach for, and rightly so for three-season use. A burner head weighs 70–100g, a 100g cartridge around 200g, and a 230g cartridge about 370g. Set-up takes seconds, the flame is instantly controllable, and there's no priming, no smell and no spillage.

The catch is the gas mix. Cheap butane-only cartridges, the sort sold for barbecues, stop performing below about 5°C and become useless well before freezing. Look for an isobutane and propane mix, typically around 70/30, which keeps enough pressure to work down to roughly -10°C if you're sensible. Butane boils at about -0.5°C, isobutane at about -12°C, propane at about -42°C, so the more propane in the mix, the better the cold performance.

Practical tricks matter as much as the blend. Keep the cartridge in your sleeping bag overnight so it starts warm. Stand the stove on a foam sit mat rather than frozen ground, because contact with cold rock chills the canister and drops the pressure. Hillwalkers using burner-on-top stoves in winter often switch to a remote-canister design with a hose, which lets you invert the cartridge and feed liquid gas to the burner, giving a much stronger flame in the cold. Inverted canisters need a little care on start-up and are best left to those who've practised with them.

Wind is gas's other weakness. The jets are easily blown about, so a foil or folding windshield makes a huge difference. Leave a gap between the windshield and the cartridge: trapping heat around a canister can over-pressurise it, which is genuinely dangerous. Remote-canister stoves are safer to shield than burner-on-top models.

Alcohol stoves: simple, light, patient

Methylated spirits burners are beautifully simple. There are no jets to clog, no O-rings to perish, no pressure to lose, and nothing to go wrong in the cold. A burner and pot stand can weigh as little as 100g, and the fuel is cheap and widely available from hardware shops and some village stores, though you shouldn't rely on finding it in a remote corner of the Highlands.

They are quiet, reliable and near-bombproof, which makes them a favourite for solo overnighters, summer trips and as a backup. The trade-off is speed and fuel weight. Meths has a much lower energy density than gas or petrol, so expect 8–12 minutes to boil a litre in still air, and considerably longer in wind. Roughly 25ml of meths boils a litre of water, but losses are high, so budget generously: a weekend can easily swallow 500ml of fuel, which is heavier than the equivalent gas cartridge.

Windshields and a decent pot stand are essential, not optional. Meths flames are almost invisible in daylight, so take care when lighting and refuelling. Carry fuel in a properly sealed bottle, and never top up a hot burner.

Multi-fuel and liquid fuel stoves

If you want one stove that works anywhere, in any temperature, this is it. Liquid-fuel stoves burn petrol, panel wipe, paraffin or kerosene, and will run on diesel at a push. They are unaffected by cold, produce serious heat, and fuel is available at almost any petrol station.

Against that: a stove, pump and bottle typically weigh 400–600g, they need priming (a splash of fuel in the preheat cup, lit, then wait for the jet to roar), they soot up pots, they smell, and they need occasional maintenance. Priming is best done outside the tent and away from anything flammable. Petrol must never be decanted near a naked flame, and never used in a stove designed for meths or gas.

For winter mountaineering, snow-melting trips, long remote routes, or cooking for a group of four, the reliability is worth the weight and fiddle.

Wind, cold and the small stuff that saves you

• Site the stove behind a boulder, in a hollow, or on the lee side of a wall, never on an exposed summit.
• Use a windshield with a gap around gas cartridges, and insulate the canister from cold ground.
• Keep a spare cartridge warm in your pack or sleeping bag.
• Always use a lid, choose a pot that matches the flame width, and don't overfill.
• Melting snow for water drinks fuel: on a winter trip, plan for two to three times your summer consumption.
• Carry a lighter plus matches in a dry bag as a backup.
• Never cook inside a closed tent. Use the porch with plenty of ventilation, because carbon monoxide kills quietly.

Matching the stove to the trip

For summer day walks and solo overnights, a small gas burner or a meths set is ideal: light, cheap and simple. For three-season backpacking and bothy trips, a gas stove with a 230g isobutane mix is the sensible default, and a windshield is the single best upgrade you can make. For winter, high and remote routes, or group cooking, choose liquid fuel or an inverted-canister gas stove with a winter mix. On longer trips, take a backup burner head or a second ignition source. A stove that fails 15km from the road turns a good day into a long, cold one.
