I was wondering about the various BTU output of fuels. Here you go:

Wood: 6,500 BTU (assumes 25% moisture in wood)
Coal: 8,500-15,500 BTU
Kerosene: 135,000 BTU
Gasoline: 125,000 BTU
Diesel: 138,000 BTU
Fuel oil: 140,000 BTU
LPG (propane): 91,500 BTU
LPG (butane): 103,000 BTU
Natural gas: 100,000 BTU
Alcohol: 65,000 BTU
Charcoal: 12,600 BTU

Its cheap, stable, long lasting and throws out a goodly amount of heat..all hail kerosene!
