When designing my rig I had gravity in mind for most processes except the HEX... as in HLT to MT = Gravity, MT to Kettle = Gravity, Kettle to Cube = Gravity..
still waiting for the power outage that makes it all worthwhile :lol:
I brew in a 2400w urn, but one of my very best purchases of all time was:
I've been impressed by the speed, but not the cost, of gas setups I've seen at brew days. A hand held element gets you pretty close for strike water, ramping up and bringing to the boil.
Edit: re last post, an average of under a dollar a brew could have something to do with it.
Seriously, though, it's plug and flick as opposed to swapping bottles at the servo, running out mid boil and other irritating chores.
Electric here, but if I lived in India I'd probably use dried cow dung, or even run tests on using human dried dung as there's plenty lying around for free. There could be a problem with the second option however if the moisture to solid content of loose stools in the mix were excessively high making the collection & drying process much too involved, messy, & inefficient too be worthwhile. It would be interesting to know though which if any of the dried products burns hotter or more efficiently. With all the chilli in the human diet over there one would think the human dried dung would burn hotter. As anyone who has partaken of a particularly hot curry for diner can confirm the human digestive tract doesn't extract all the heat from the meal by screaming from the often painful arse ring burning during their early morning bowel evacuation the next day! As I have no intention of going to India these burning questions will sadly have to go unanswered for a while at least .
What I have found for doing a single batch on my old gas rig used 4.5kg LPG which these days is about $14 (from memory) vs my new rig with a 2200w + 1500w BIAB which costs about $3 a brew.
I normally do around 14 brews a year so my new electric system costs $42 a year vs $196 so saving around $150 a year on running costs.
