At the other end of the scale, I have a 19kg propane bottle, and have done 4 x 90 minute boils (23l finished volume) so far from it. It appears to be a bit over 3/4 full still, although with no gauge it's difficult to tell. I am judging by looking at the level that the condensation stops forming on the bottle when it's in use and using that as the liquid level.
If that is the case, then if we said it was 80% full, I'd expect to get 20 x 90 minute boils from a 19Kg bottle, and the refill price is £37 - so about £1.85 per boil in gas. Or about a kilo of propane per boil
I only use one burner compared to Aleman's 2, and I run my regulator at 1 bar as opposed to his 2 bar - so that accounts for a 4X difference in gas used.
