Condensation shouldn't be an issue as long as you're not cooling below the current dew point.
However, after experiencing one of these underfloor cooling systems once, I can say that the biggest issue is that cold air tends to be heavier and thus stay down. So in order to cool the entire room, not just the layer of air right above the floor, you need something to move the air, which is probably why they're providing fans. Either that or you can just lie on the floor all the time...
Floor heating works because warm air rises. I never understood why 'floor' cooling wasn't piped through the ceiling, instead. There are probably some engineering or heat transfer issues there, though.
What is your brewing setup? I've used your grain quantities in BeerSmith with a Braumeister 20L setup for the out of the box efficiency (without stirring the malt during mashing or a finer grind or extra boiling) and it gave me a post-boil of 1.042, which seems to fit with your result so I'd guess you had an efficiency issue. How did the mashing go?
I've noticed that when boiling for the standard 1 hour, I get about a 10% increase in gravity (for the digits after the 1 - that is, pre-boil of 1.064 leads to post-boil of 1.070 ish), so in your case 1.037 to 1.041 would check out for me.
For my brewing setup, 30 minutes at 63C doesn't really cut it, I've tried it and noticed 60 minutes or even 90 minutes work way better. But then I mostly use kveik and the indication seems to be for longer mash times (something about it being unable to digest sugars made of 3+ units).
I'm not sure I get your last point. If your FG is higher than expected, you should reasonably have more sugars left over from fermentation, so more residual sweetness.
Regardless, I'd suggest RDWHAHB, and see what you get out of this. Do share your final results, I am curious what it's like.
Out of lazyness, I just let all my beers sit in the fermenter for 2 weeks and that seems to work out just fine. Some finish bubbling after 2 days, some after 12.
Edited to add: just noticed from your yeast link, you also use an all-in-one system, does it suffer from the same low efficiency issues as the Braumeister, I wonder?
The software calculated efficiency for the Braumeister is spot on for me if just using it like set it and forget it, so about 65%. I can up that with stopping the pump during mashing, opening the thing and stirring the mash about once every 30 minutes in my 90 min mash. Also by milling the malt a bit finer. But too fine, and I get a stuck mash. With this, I managed around 75, or how much the software sets as standard for pot and cooler method, so I'm happy with that.
I also start the brew with 23ish liters of strike water, dump 6 kg of malt in there and sparge with 5-6 liters at 80C. Boil 1 hr and end up with 18-19 liters in the fermenter with the rest full of trub in the Braumeister (2-3 liters maybe?) I never measured how much is left and I can sparge with 4 or 6L. I just eyeball it according to how much wort is in when I lift the malt pipe.
In your case, I'd say maybe the mash did not go very well.
I wouldn't be too worried about the body. It could be that your fermentation just stopped a bit higher because all that's left is longer sugars, unfermentable, but good for the body. One way to find out...
add to that that google turned to crap nowadays and just pushes meaningless bot generated content in the top pages... it's getting almost impossible to use it to find stuff. not sure about other engines because I only started recently being search-engine-curious, so no idea how they were like before
Also adding to the list of nice things - a picture of the current dictator on all public offices and classrooms. Work and school weeks from Monday to Saturday and a Sunday in which you had to do mandatory free time activities, like go to communist youth clubs, participate in parades for the glory of the state, or plant flowers or do random maintenance work in the park.
I've noticed the arguments tend to center around the notion that 'that wasn't true communism' and that the notions presented by Marx et al. were not properly implemented.
Fair enough, I can agree with that, but I'd wonder what makes us think that we would do it better next time? How do you actually prevent consolidation of power in the hands of the select few (in any system, for that matter, not just the ideal communism)?
Obligatory capitalism is bad too (but at least I'm in less danger of getting vanned in the middle of the night for insulting random great leader - attemtping to undermine the social order or whatever they called thoughtcrimes).
