| Sep 19, 2015 at 15:00 | comment | added | Sebastian Riese | Wow, a candle really outputs 80 W, that's more than I would have expected (after all, that is about the power a human can output when doing continuous work). Another analogy: A camping stove has (depending on the model) around $4\,\mathrm{kW}$ of power. (But you will see, the answer depends on a lot of factors – the flame of a camping stove is a lot smaller than the flames of a 20 or so candles). | |

As is to be expected, output varies substantially with what is done with the heat produced - and an open fire is said to be say 5%-15% efficient while an enclosed wood-burner with pelletised wood can exceed 90%. | |

Put in a quantity of water and time how long it takes to boil. Now imagine it was a regular kettle and think about how big of a fire you would need underneath it to boil the same water in the same time. | |
