MQ, does your pot have a tap?
And kidding aside, I'd be interested in the running cost differences between elements vs domestic hob vs propane cylinder.
Apparently it costs about 2.5p to boil a full kettle (say 1.5l to keep the math simple).
So, in theory, a 30l boil is 20 X the amount + 2 X the elements = £1.
But it takes a lot longer to get to the boil than the kettle, and it's kept going for a lot longer too. Does maintaining the boil use less electricity than it takes to get there? Sounds logical but then the elements stay at the same temperature, don't they..?
Gas is cheaper but takes a lot longer and from what everyone has said the time goes up exponentially the greater the volume of liquid.
I know cost isn't the primary concern but it might be worth considering if one method were significantly dearer, especially if someone brews frequently.
