Not sure about the beer but yeasy will be dead. Could be bad fusels before they conked out. Anyway sounds as if your plugs into the contoller were reversed. Its trying to cool, but heater plugged into cooler port so keeps getting hotter.
If this is all you had in 20 to 23 litres you are short around 1kg of fermentables, hence the sg of 1.031. The steeped grains will add a bit, but not a lot. Their base kit is 1.7kg lager plus "body blend" which is 1kg of fermentables (or close to) to get into the 1.04+ range.
Used this in a 10L experimental batch - full packet at 1.040 and went down to 1.007 - kegged it. Added pineapple & passionfruit at end (or near end) fermentation. Certainly brings a nice tartness to it, but not a full on sour - so makes a great summer quencher. Don't have a pH meter but used...
Got one in the last batch available late last year. Does catch a lot and forms a nice "trub cake" on it. Shall take a pic next time. So it works.
Also it has a couple of lift points but do need to give it a bend to extract past the malt pipe supports. So for cleaning usually lay the guten on...
There is chlorine and chloramine which water authorities use. Chlorine can dissipate with boiling or leaving exposed for a period of time before using (like overnight) or by filtering. Chloramine is harder to get rid of. SMB or campden tablets will do it as will ascorbic acid (vitamin C). I use...
I believe the brezilla has the distillation option with the alcoengine (kegland), not the the guten. I have the guten and did consider distillation so looked at the bz at the time but realised I didn't need that much extra alcohol at home.
Your yeast starter has a specific gravity of around 1.037, so you slightly diluted the wort of 1.07. As such to calculate the ABV of your finished beer you need to use 1.062 as that is the sg of your total wort that is to be fermented.
Just get them to bring the ingredients around and have them stay and do the brew with you. Can ferment at your place as you have the room, then get them to help/do the bottling. They may then leave you some bottles as a thank you for helping/teaching them to brew and borrowing your equipment..
You would likely need a reverse spunding valve or something to relieve the negative pressure (open PRV) as the wort cools, or you will buckle the kegs if sealed tightly. Both these methods will let oxygen in though, unless you hook it up to CO2 in some fashion. Have you seen the shapes of the...
