He carried what was the state of the art gear for the time - a flint and some dried mushrooms for kindling. To be fair to Otzi, he lived and died about 5300 years ago, but he wasn’t the last to get caught out in such a way. In more recent times when my friends the twins Willie and Damian Benegas made the first ascent of the well named Crystal Snake on Nuptse in Nepal in 2003, they climbed about a dozen steep ice pitches only to discover on their bivvy ledge that their stove didn’t work. After a cold and thirsty night, the next day they had no choice but to retreat back down their route and across the Western Cwm to Everest’s Camp 2, pick up another stove and re-climb the route to the summit! A reliable stove is an essential. The development of stoves that could be carried whilst climbing enabled most of the more challenging mountains of the world to be ascended. The first such stove used pressurised paraffin (also known as kerosene) and was invented in 1892 by a Swede called Hans Wilhelm Lindquist. His stoves became the famous and still cutting edge brand Primus. Their iconic brass tanked marvels were used on everything, everywhere until the 1970s. I have still got a couple in my cellar used in the Himalaya in 1979 and I bet in no time I could get them fired up again. Apparently they are now collector’s items. These days we are lucky in that we can choose from a vast range of stoves that have been specifically designed for different outdoor uses. The choice is however also a part of the problem. Which one from the dazzling array is the most suitable for the type of thing we do? Asking the following questions can help to narrow down the choices: • How will you use it? Will it be just for melting snow and making brews or other fluid, or will you be cooking meals on it? And how many people will it need to provide for? • What type or types of fuel will it need? There can be as many availability problems with some fuels between the UK and France as there might be in Mongolia or Kyrgyzstan. You can’t take any fuels on aeroplanes, not even empty used MSR fuel bottles nor can it be sent by regular UK post or courier. Freighting gas canisters to another country is a nightmare and is unnecessary. • Where will you use it? High altitude and extreme cold make a big difference to performance - where at sea level it could take you a single minute to boil a pot of water, at 3000m in the Alps the same pot would take four times as long and at 6000m in the Himalaya a staggering 15 times as long. • Will it be used in a hut, a tent a bivvy or out in the open? • Will you have to carry it? • What other gadgets are worth their weight in adding performance? Irritatingly, quite often the answer to all these questions might be yes. You need a stove that will do everything from frying the bacon on the campsite in Llanberis to melting some snow for a much needed brew on an alpine bivvy. Often but not always - something that attempts to do everything does nothing that well. This frustration and the desire to reduce the number of people who died from altitude related problems, often caused or made worse by dehydration lead to another giant design leap forward in stove design. The metaphorical leap was made by a Seattle based mountaineer and engineer called Larry Penberthy (1916-2001). Amongst much else in a very full life he created the organisation Mountain Safety Research (known today as MSR), made new stronger ice axes and a stove that was specifically designed to work in the cold and at altitude. The man was a genius. This page: Tim Emmett resting after climbing 800m through the night at the start of the first ascent of the East Face of Kedar Dome (6831m) in India.

Here are my thoughts on a selection of both new and classic stoves that I have used in a variety of conditions over the years. It is worth remembering that all these stoves and their fuel are potentially dangerous: at the very least, having your tent burn down at night in the middle of nowhere is not a good start to a climb. the recent arrival of the OmniLite (BELOW) is even more compact and lightweight, and I’ve been very impressed with it. On the other hand for superlight backpacking their new tiny semi multi fuel stove the Lander which uses gas cartridges or Coleman fuel might be the state of the art! Multi fuel pressurised liquid stoves Trangias are to these types of stoves like Hoovers are to vacuum cleaners. They have become the generic term for them. They are another Swedish invention and a major part of their appeal is their simplicity. Each is a contained unit of pots, stove and windbreak that burns what we in the UK call methylated spirits. This fuel is known by other names in many countries and is not available at all in some. There is a useful chart on the Trangia web site to help you to ask for and find suppliers of what you need to run the stove on your travels. The stoves are fairly light, provide a stable system and a good windbreak. They require little maintenance and are unbreakable, pretty much. They do have some disadvantages however. The heat is difficult to control and they are a bit on the bulky side for some uses. The burning of the methylated spirits also blackens the pans with soot and more significantly it is possible to spill fuel which could cause a fire. Even more than any other stove, they should definitely not be used inside an inner tent or refilled when lit. Of the wide range of Trangia stoves available I favour the small 27 model with non stick pans or for a bigger group the 25 with non stick pans. It is also possible to get a Trangia conversion kit that enables you to burn propane/butane cartridges or even transforms it into a multi fuel stove along the lines described above. These are the latest incarnation of the work started by Primus and subsequently developed by MSR. They are great because they are very fuel efficient as they burn vapour and they can be used with a variety of fuels, depending on what is available. They are also relatively stable and lightweight. Some of them are designed purely for expedition use to produce a fierce heat for melting snow but lack the fine control needed for cooking. They consist of a burner head with pan supports that is linked by a semi rigid or flexible pipe to a separate fuel bottle. They can usually be stripped down easily to clean or maintain. The first of these was produced by MSR and their latest version of it is the iconic XGK EX (BELOW). It can boil a litre of water in about 3 minutes using kerosene and less using petrol or white gas (Coleman Fuel) and a bit more on diesel. It is easy to clean using a shaker jet cleaner and is more stable than any of the previous versions I have owned since 1980. It is however not very easy to use for gentle heating and cooking but turns snow to boiling water a treat. MSR also produce both lighter and less ferocious stoves based on the same idea. The Whisperlite Multifuel is very lightweight and great for general camping as the flame can be easily adjusted and controlled. As its name implies it is less of a beast that the XGK. The Dragonfly is an attempt to compromise between the other two, and a good all-rounder for many people. When you buy one of these stoves you must buy a separate MSR fuel bottle. The bottles look a bit like a standard Sigg drinking bottle, but it is dangerous to use one of these as they are not strong enough and could easily explode with the pressure. Primus came relatively late to this type of multifuel stove, but I thought their Omnifuel stove was a winner the first time I used one in western Mongolia a few years ago. It can even use propane/ butane gas canisters and comes supplied with the correct liquid fuel bottle. As if that wasn’t enough Liquid Fuel Burning Stoves Stoves that use Gas Canisters There are two types of gas canister that are used in lightweight stoves. The original and still a strong brand in France is the Camping Gaz Bluet, or ‘Bluey’. They were good in their day, but only contain Butane gas which gives pretty poor performance in cold conditions and they do not attach to the stove directly with a screw valve, but need to be punctured to attach. This means you can’t detach them until they are empty and even then there is always some excess gas in the canister. Never do this in a tent for obvious reasons. Go Systems make a useful adaptor that enables you to use these canisters on stoves that use screw on ones. The most widely available canisters these days are screw on and are filled with a mixture of butane and propane, and are far better. The propane mix gives a better performance in cold conditions. The Primus ETA Power (TOP) is a windshield and non stick pan system, a bit like the Trangia but due to the design features of the pan (having a heat exchanger on the bottom) and the stove burner, they are incredibly efficient. On Peak Lenin in 2009, we only used about half of the gas supply we had calculated that we would need. The system is big enough for three or as we did in Scotland this summer four people at a squeeze. As with any stove, don’t rely 100% on the ignition system not letting you down - take matches or a lighter! The Edelrid Stormy Evo: for years the name Stormy when referring to a stove meant a particular super efficient stove that could be hung from a tent or off a belay on a bivvy ledge. This new version from Edelrid is exactly that, although it also stands solidly on the ground too. It improves on the original in that the pan is a sensible size for scooping in and melting snow and has handles that you can grip without needing gloves. It is however not just a blast furnace, but is quite adjustable for cooking too. My tip for use is to have the burner head permanently assembled in the windshield, rather than packed up inside, which makes for a bit less faff when you are trying to get sorted at the end of a long day. Tower Stoves Jetboils are really superb bivvy stoves. They have many great features including the fact that the pot 62 w w w. c l i m b m ag a z i n e . c o m MARC H 2012 76928_60-63_GEARING UP_pP.indd 62 24/01/2012 15:32 and Stoves Food is safely clipped onto the stove and it is contained in an insulated sleeve so you can hold it in your hands or between your knees. You can also hang them or stand them on the ground. I came a bit late to Jetboils, and used them for the first time on Everest in 2005. These days there are four different models of the original as well as a group system. The Zip is the basic original version, the Flash (LOWER) lives up to its name with an ignition system and heat warning panels on the insulated pot jacket and the Sol which is made with either Aluminium or Titanium and has ‘a Thermo Regulator system’. In other words, it works better at altitude and in the cold. If you use small size gas canisters the whole thing can be stored inside the pot/mug on all models. My recommendation for using Jetboils if there are two of you is to take two pots, then all you have to debate is who gets the first brew. The MSR Reactor (RIGHT) is strange, brilliant, and unlike any other stove discussed here. It should be more popular than I think it is. It is perhaps the most fuel efficient stove in the world and works well in wind, cold and high altitude conditions. It is supplied with a big pot with a see through lid to check how things are going without letting out precious heat. The radiant burner has a heat exchanger but doesn’t have any flames. It is clever and it works. It’s not cheap, but you not only get what you pay for, you will over time reclaim the cost against saved fuel. Personally I would like the pot to be attached to the stove in the same way as on the Jetboils, but overall it is a minor quibble with this superb stove. Super lightweights The MSR Pocket Rocket is one of those products whose name tells you all you need to know. Use it with a small gas canister and a windshield or in some other sheltered place. The Soto Micro Regulator is another tiny fold up stove but despite is minimal weight and small size is also fitted with a regulator, an ignition system and big easy to use control. The regulator means it keeps working well in low temperatures, which makes a big difference on a cold bivvy. Sometimes it is possible to go too far. I have known people who are so determined to minimise weight that they cut back on everything too much. I have heard of people taking a super cheap solid fuel stove on the mountains on the basis that they are enough with which to make a brew and only cost about £4. These stoves are really inefficient, don’t cope with even a breeze very well, and the fuel blocks themselves are quite heavy. Additional things that can help Aluminium foil windshields were first developed by MSR and are available separately for use with any stove. Coghlans also make something along the same lines. MSR’s Heat Exchanger is essentially a bit of corrugated metal that wraps round a pan, channelling heat from the stove onto the sides of the pan. It saves fuel, but has some weight and bulk itself. Jetboil Fluxring Pan and the ETA Power Pan are both sold separately and are great for use with groups and are easier to fill and stir than the standard Jetboil pot. It has a heat exchanger on the base that drastically improves performance and saves fuel. A base plate under any stove can help its performance in snow. MSR make a light folding one called the Trilium, but a thin bit of plywood or a small chopping board will help to stop the stove melting itself into the snow and becoming unstable. Food Food is a very personal thing. One thing is for sure though that in the mountains we need to fend off dehydration and replace the calories burned. If weight isn’t too much of an issue or sometimes for the first night of a multi day trip I favour Wayfarers boil in the bag food. It is real food. Sure it’s not particularly light, but it really does the trick, and you can eat it out of the bag. There are plenty of veggie options and puddings in the range too. Of the wide range of dried foods that are about, my favourite is the Kudrati vegetarian curries. They are best shared with others so you can have two or three varieties. Instead of rice or chapatis, try couscous and pitta breads. For breakfast my favourites these days are from supermarkets. The instant porridges in a pot that just require hot water and a stir do the trick. If you are a coffee addict or just use the caffeine blast to get going on an early start in the mountains, you could do no better than Growers Cup (ABOVE). It is real coffee in a brown paper bag/coffee filter. You just open the top, pour in hot water and pour it out of the spout at the side. Voila! Alternatively Jetboil make a coffee press that works with their pots, but it makes a lot more mess. If I’m out with a group I also always carry a few energy gels to get people going when collapse approaches and sometimes for a treat shove a Clif Bar in my pack too - but don’t carry one as emergency rations, since you’ll have eaten it long before you need it. Kendal Mint Cake, for this reason, could be a good item to carry for emergencies, since it will still be there when you really need it! n this page top: The Primus ETA Power in action on Peak Lenin (7134m), the second-highest mountains in the Pamirs in Gorno-Badakhshan on the border of Tajikistan and Kyrgyzstan.
