That's mighty fancy...I understand how a GF type device works...with a basic pot system and no pump what do users do to shift the liquids about etc?

My typical modus operandi:
Electric boiler in kitchen on worktop next to coolbox mashtun which is on 6 inches lower level worktop.
20litrs strike water from cold filtered tap into 25ltr plastic wine fermenter, walk over and empty into boiler. This is the only 'big lift' since cold water (low risk).
15-20ltr strike water at 74-75C from boiler to to mash tun using 3ltr plastic jug.
Refill boiler with another 15-20ltrs cold water to heat for sparge.
Drain wort from mash tun via gravity though wide bore silcon tube to 25ltr fermenting bucket. 1st run about 10ltrs, 2nd runnings approx 6ltrs. Pour last sparge water (10ltrs )into mash tun.
Move boiler outside and set up for boil.....carefully walk out kitchen with 15lts warm wort and empty into boiler (which is set up on a low kids table).
Drain 3rd runnings into bucket and walk out and empty into boiler.
After boil and cooling, drain wort from tap into 25ltr wine fermenter in 3 lots of approx 7-8ltrs (used to shake to oxygenate but don't bother now) - empty into SS Brewtech fermenter..so only moving 7-8kg at a time.
Done.
