Gear talk: fitting the Edelrid Hexon stove to the Trangia Stormcooker

In addition to producing the lightweight Hexon stove, Edelrid sold the Tradapter, a simple folding support that enables the multi-fuel Hexon to be fitted in the Trangia Stormcooker.

The two piece Swedish made Trangia Stormcookers comes as small (27) and large (25) two-piece windshields that support a burner whilst also protecting it from wind, while also allowing ventilation. The size of cooker you have usually depends on how many in your party, small size 27 for 1-2, large size 25 for 3-4. Following a change that Trangia made to the bottom section, both sizes were designed to have the standard Trangia alcohol based fuel burner (B25) installed or a gas burner (GB74) installed. Trangia more recently added a gel or solid fuel burner to their product range. There are a number of third party burners that can be fitted into a Stormcooker. Amongst these, Optimus produced a Trangia adapter (8016303) to enable an Optimus Nova or Nova + to be fitted in the Stormcooker (which also fits the Primus Omnifuel). In addition, Trangia sell their Multifuel burner that can slot straight in, burning either liquid petroleum based fuels, or from gas canisters via its EN417 lindal valve connector. The Tradapter was an ‘official’ Edelrid product designed to fit to their Hexon Multi-fuel stove enabling that burner to be installed in the Trangia Stormcooker windshield.

It really is easy to fit the Edelrid Hexon to the Stormcooker. It requires no tools, just the purpose built Edelrid Tradapter. The Hexon stove has three sprung titanium legs. These are simply pulled out of the holes in which they swivel, leaving the body with burner inside. This is fed up through the hole in the centre of the base/bottom half of the Stormcooker and the opened Tradapter closed and clipped around it, the lugs on the Tradapter hooking into and under the slots in the side of the Hexon stove body. The fuel hose is then fed through the larger hole in the side of the base/bottom half of the Stormcooker. This can be attached to either gas canister or to the Hexon pump, screwed into a fuel bottle. The Hexon has an easily accessible valve control attached to the fuel supply end of the hose and there is no need to access and control underneath or beside the burner. Then it is simply light the gas, or if using a liquid fuel, prime in the standard manner. This can be done either before or following the top half of the Stormcooker being fitted. Lighting afterward will give a little more wind protection at this time.

Removing the three support legs from the Hexon reduces the weight a little, from 224g to 192g. The Tradapter itself weighs 15g. It is almost pointless discussing this as a way of keeping things lightweight as the two-part Trangia windshield is no lightweight. Trangia have produced their cooker sets in various materials over the years, mine is the large size Ultralight Anodised Aluminium. The lower aluminium windshield section weighs 120g and upper section 201g, 321g in total. The coated non-stick versions are heavier. The windshield is pretty bulky too. The Trangia Stormcooker was designed to get every last BTU out of the Trangia burner, which uses a relatively inefficient fuel.

What the combination of Trangia windshield and Hexon multi-fuel stove offers is an incredibly stable and windproof set up with efficient adjustable flame control. Long burning and suitable for ‘proper’ cooking, rather than simply water boiling. I wouldn’t want this set up for lightweight backpacking at all as it is a bulky heavy rig, however, combined with the smaller 27 Stormcooker, with more than just a solo camper in the party, in harsh winter conditions, and it could be a viable option.

The Edelrid Hexon burns hot. It knocks out a lot of BTUs. I have never felt the need to run it on full bore, instead keeping it tweaked down. I am never in that much of a hurry! I have not experienced any warping or detrimental effects with the Stormcooker when using this burner in it, but do wonder if prolonged full bore use might cause issues. But it was made for it, so who knows!

In common with the Edelrid Hexon stove, the Tradapter has been discontinued by Edelrid but at the time of writing, again in common with the Hexon, can still be purchased from a handful of dealers holding old stock. Though how long that will remain the case is uncertain.

  1. Wanted to do this for years however the price of Trangia’s own burner is so expensive.
    My Trangia is over 30+ years old and still going strong and would love to add multi-fuel to it.
    The review of this stove is coming up as a 404 error by the way.

    • There are a number of options for fitting some multi-fuel burners to the Trangia. Fashioning your own support brackets is always an option, not something I would like to do however. I should have sorted the review post now, try again
