I tried this the other week in the shed while i was messing about with coke can meths burner,put it inside my gas bottle burner and was suprised at the amount of heat it gave off,even the can stove on it's own warms the shed up quite quickly,i also tried the alchol jel you get for sterilising your hands in hospitals etc, that woks quite well.

IIRC, each tea light is giving off between 25 watts and 80 watts so you could have

7 X 80 = 560 Watts heat output from that thing.

Not a massive 3KW heater, but not bad for

7 X 2p = £0:14 worth of candles

(if you get Asda's cheap tea lights)

You could probably fit at least 20 tea lights into this heater by adding a piece of flat plate inside for them to sit on, but I think that's probably taking things a tad too far :mrgreen: The 7 tealights I used ended up burning for around 2 hours, making the top of the gas bottle too hot to touch, but all things considered I think I'll stick with alcohol as the main fuel.

Great post, thanks for sharing, its always great to see how we adapt things we find or have lying aroung to become functional pieces of survival equipment. Well done, but as mentioned perhaps buy a CO detector if burning such fuels and in containers not ment for this purpose.

Burning alcohol based fuels produces a minimum amount of CO2. If you have a gas fire fitted, or used to have, and you still have your wall ventilators, fumes of any kind won't be a problem. As long as you make sure to remove all paint/glue residues from the gas bottle and your alcohol container and only replace them with paints that are rated to cope with temperatures up to 500 C you should be ok. A paraffin heater produces much more in the way of unpleasant gasses, along with soot particles and the smell of paraffin. Personally I don't mind the smell of burning parrafin, but there you go :mrgreen: Of course, our American friends take alcohol burning to a different level, adding essential oils to the alcohol gel, or small amounts of vegetable oil or salt to make the flame spit and crackle slightly for the full open fire effect :) I did a search online for alcohol burning stoves and some of the commercially available items are pretty spectacular, but they also come with a spectacular price...

That's why mine is made from a cheap chimnea from a budget shop for about £30 and three 1/2 L bioethanol burning tins which cost £20 for six making the complete assembly only £50, and it doesn't look too bad (for those who care about that sort of thing).

CO2, Carbon Dioxide, isn't so bad. You'll notice its presence long before it gets to lethal levels (after all, your breathing reflex is caused by CO2 build up not lack of oxygen)

CO, Carbon Monoxide, on the other hand is poisonous (starting around 30 ppm, I think) and cannot be detected by the human body.


Alcohol is a safer indoor fuel, however if you're going to burn anything inside anywhere get yourself a CO detector.

This is the one I bought http://www.lloydspharmacy.com/en/lifesa ... larm-35503

At 11 quid delivered and good for seven years why wouldn't you ?

Superb post, thanks for that.

The gel fuel pots are called 'chafing fuel' if I remember rightly, used to keep food on buffets warm.
