At 11:20 I corrected the direction where the cooker faces to. The water is very warm, if I bathed/showered I might add a bit of cold water to it, so it's on the verge of being uncomfortable - for me.
Also it seems the water expanded? The metal of the keg should expand due to heat, which would be larger volume, but now the water flows out of the opening at the top. Gonna post pics later.
