Hi,

I just tried boiling 500ml of water with my pocket Esbit stove. I have detailed statistics, but the executive summary is that it took 40 minutes and 5 tablets.

The weather was warm and sunny, but quite windy. Ambient temperature about 20°C, and we are pretty much at sea level here. I was impressed at how the Esbit tablet remained lit even as the wind caught it. I will repeat the test in the garage, where there will be draughts but no wind.

Also, the fuel makes a sooty deposit on the pan, which is annoying and will make everything it touches black.

I made a cup of tea (500ml) with the boiling water, which was quite nice after waiting for 40 minutes.
