Gary said:Let us know how you get on Nigel - I havent tried the ali set with greenheat so it would be good to know.
Also one tip - I usually build a small twig base, like a mini temperate fire lay, and place the windshield over this
Well my findings are:
Swedish Army Trangia Ali Set
1 sachet of Greenheat
1/2 pint of cold tap water in the smaller pot (equal to a mug of tea)
Temperate fire lay of about 2cm in height (to raise sachet nearer pot and as Gary says, insulate it from the ground)
Time taken to a good rolling boil 11min 30sec
This might be improved on by raising the platform higher so the flame could be a little nearer the pot. There was about 7min of usefull life left in the sachet - easliy enough for a brew or some simple cooking e.g noodles/pasta
Just for fun I timed the meths burner:
Time taken to a good rolling boil 7min 30sec
This was from a cold start, only its second light and about half full of fuel.
So IMHO the Greenheat sachets are pretty good stuff. It saves you the trouble of carrying meths (with the attatched risk of spillage in your pack) and the burner. It has quite a pleasent smell, unlike hexamine which I believe is also toxic and is harder to light. Another small bonus is that it dosent leave gunk on the bottom of the pan - so pretty clean. Just the stuff for a potter in the woods or a lightweight weekend away :biggthump
