Long burn alcohol stove?

[sam_uk]

Hi this is my first post here, reading the threads it seems like there is a good pool of knowledge on Alcohol stoves!

I'm looking for a alcohol stove that:

1, Is unpressurised
2, Has a burn time of at least 5 hours
3, Is no more than 19cm in diameter

My third criteria rules out
The heatmate

And the Origo
http://www.elyboatchandlers.com/origo-hobs-and-burners/origo-1500-spirit-hob

My extensive googling has turned up this AB-13 Folding Alcohol Stove with external tank.
http://www.tripleatripleo.com/stoves/

So is the AB-13 the only external tank unpressurised alcohol stove on the market? Or are there others?

Thanks

Sam

Hi Sam, welcome aboard

I'm not familiar with the first two, the third can be obtained from Mat at UKhammocks

Considering the criteria, in what situation do you envisage using the stove? Why the five hours burn time?

After a point, gas is more efficient for the weight.

If it's a small, lightweight stove then minbull designs have loads of stuff.

Yeah I immediately though of Tinny and minibull design - who has plenty of external feed models (muchos videos on youtube). You would probably need an external tank wth connecting feed pipe. I've never seen one with a large tank attached (as in a coleman petrol ones), but I'm assuming that would have a heat sink/cooling effect to it's detriment. 19cm (190mm?) seems pretty wide for a maximum diameter. I am also intrigued by the 5 hour burn time...is someone makin' sourmash??!!!

Blimey mate have you found a source of cheap meths? Oh welcome to the forum by the way. Paul

Welcome to the community. I too am intrigued to know what you intend to cook for 5 hours. Or are you building a central heating system for your tent? :-P

lmao here! :happy-clapping:

There isnt really much point in trying to use a meths stove for 5 hours. The whole point of a meths stove is light/compact. To keep a stove going for that long you would need allot of meths which would just defeat the whole purpose of having stove in first place.

You would be much better off getting a gas stove and if its weight as your main concern get something like the Crux Weekend HD or if you want something little bigger I would recomend one of the Trangia Cooksets with Gas attachment.

Or alternatively just build a fire ;)

Isn't Meths half the calorific value of other liquid fuels? Therefore, 5 hrs of meths burning = 10 of say, Petrol/Coleman Fuel/Paraffin etc

Hi all thanks for the replies :)

I am indeed building central heating, but for a boat not a tent :)

It will primarily be a woodstove with external flue. I'd just like something I can stick in there as a backup in case there is no wood about.

Gas / petrol / pressurised fuel etc make me nervous on a boat. Hence the meths..

Also considering a paraffin backup, but apart from greenhouse heaters I don't think there are any unpressurised?

Will check out minibull design, thanks

Thanks

Would have thought diesel was the way to go on a boat sam, thats safer than spirit. Espacher make diesel marine heaters that normally run off the main fuel tank.
Not trying to urinate on your pyrotechnics but not sure the insurance man would be to happy either,I know when i had boats the boat safety certificate people where very touchy about any liquid fuel. Paul

Thanks Paul,

I know of Espacher etc, there are also some nice (but very expensive) drip diesel units such as taylors.

I mainly want a very small woodstove that I am designing to my requirements. But just want a backup in case wood is unavailable.

Origo stoves (in my first post) are pretty safe I think, I am certainly much happier with my origo stove than the old butane one.

The other solution is that I could just make the stove 3cm wider and it would take the origo cartridge with circa 8hours burn time. But 230mm square stainless box section is not widely available, whereas 200mm is..

Thanks

Now having second thoughts about alcohol and considering diesel.

Seems like I could use these with a 1.5l tank: http://www.campmor.com/primus-1-5-l-fuel-bottle.shtml

Two questions:

1. How often do you have to pump these stoves to keep them going? every 10mins? 20? half hour? Longer?

2. Can you get a longer fuel line for these stoves, the supplied ones seem quite short

Thanks
