I was thinking a computer wouldn't need too big a loop to sink its own heat. Copper is definitely the wrong material for that, did this guy just put it in the forms on his own without consulting any of his contractors? Or was this entirely DIY.

Arrath posted:Huh. I was thinking a computer wouldn't need too big a loop to sink its own heat. Maybe not if it was in a different media - like forced air (with fins on the copper) or a water to water exchanger. The calculations are easy and readily available because they're the same things you'd be using for radiant heat in the slab. 6 meters/yards of 1/2" copper isn't gonna do poo poo. I'm not sure there's any way to ever make this work properly because you need to control the incoming water temperature between something like 85 to 120 or you'll do damage to floor finishing and the circulator pump itself. Plus what's the point? If you wanted to recycle that waste heat there are better ways to do it (indirect fired water heater tank) and let's pretend the system could be made to be efficient: you're still heating up the drat room you tried to get the heat out of in the first place so now you need to over-air condition that one room in the summer. This is an "idea" that wasn't even thought 1/4 of the way through by someone who has zero experience with anything relevant to what they are doing yet no awareness of that and a complete lack of imagination that it just might be more complicated that it looks.

LOL I didn't look that close the first time and it's like 20 feet of pipe? In the time he took to make it he could have installed 500' of pex in a nice long loop throughout the entire footprint of the house.

Goddamn that pisses me off. In a condo I was working on, the owner put control valves and the shower head on opposite sides of the shower. It opened my eyes up that with just a little extra piping you can make it feel so luxurious because you don't get sprayed with the water while you adjust it. (the downside to me is that it takes longer for the temp change to register on the other end) And that's all they had to do here! Just route the shower head to the proper wall. It's one pipe!

Motronic posted:Maybe not if it was in a different media - like forced air (with fins on the copper) or a water to water exchanger. It reminds me of the awful idea Linus Tech Tips had. When his channel was based in a house he wanted all of the editors he stuck in one of the bedrooms with 5 high end PCs to be able to hook up to a room spanning copper line that would take the hot water from their CPU and GPU loops and send it to radiators mounted outside the window. He didn't use a larger automotive radiator or anything, he just strapped a bunch of computer radiators together because he's a clown. Anyway, after doing apparently no research, they spent a lot of time putting it together; even getting one of the guy's dads to help because he was a plumber. Then they just filled it up with tap water and it stopped working pretty quickly because stuff grew in the loop since there was no prevention done. I remember following to see them double down later and add a filter and a UV aquarium filter inline, but eventually they scrapped it and just moved to a new office. They basically had the critical thinking of "I know how to build a PC, so everything must work like that" except that they didn't even take what they should've known about water cooling PCs into account, nor the history of water cooling PCs that started with automotive heater cores when there were no computer specific water cooling parts. It was one of several projects they clearly just did with no foresight or thought into how to actually make it work. It made me realize that the whole LTT channel is really more about teenager youtube clicks than useful information. I hesitate to link it because they don't deserve views, but he's got millions of views anyway so here's part 1 if anyone's morbidly curious.

Mind you, they have sort of developed as a channel over the last 7 years - both Linus himself and the other staff seem more realistic about what can and can't be done with watercooling now than back then. Though I conceptually love the idea of "just hook your PC into the cooling supply".

That reminds me of how old factories would, instead of electrical power, have rotating axles that spanned the length of the factory floor, and each tool would have a belt or whatever that connected it to that axle to get power.

It's a poorly executed flex. I don't know what the head is on his pump, but it's probably not a stock PC unit as even a short run of 1/2" copper would be too much for it. , If he's using an actual circulation pump then his run is hilariously short for heat dissipation. Nothing makes sense in that picture if he actually thought things through. There's a reason why nearly every PC cooling system on the market uses grills getting as much air surface area as possible and not just a copper tube.

fralbjabar posted:Some in-floor heat crappy construction: I'll say you'll still be heating the ground, your floor will just be colder. I'd look into if it's possible to run a liner or something through your existing pipes. Or radiators over forced air. Heat pumps work with hydronic heating too, it's more common for them to work like that here than direct to air.

I've never done tile, but I've seen a few episodes of Holmes and This Old House. Pretty sure if the floor is a slab you just throw some thin set down and place your tile...

Because usually it means they are covering up a major fuckup. On some rare occasions it's a sub who does great work but has terrible business sense. But way more often than not, it's a problem.

PremiumSupport posted:I've never done tile, but I've seen a few episodes of Holmes and This Old House. Yeah, exactly this. You may need to do some leveling or crack repair but uh probably not 3 inches of concrete. My guess is the guy screwed up the plumbing/toilet flange and his solution was to put another on top of it and raise the floor.

I'm think they were going for a curbless shower (if you open the op's imgur album there's a couple additional photos) but didn't want to have to break out the slab to install the drain????

That was gonna be my guess. My shower tray ended up being on a riser to lift it despite (or possibly because) being low profile because it was the only way to get sufficient height to align the drain with the actual pipe which couldn't be changed without changing the height of the joint to the stack and why both with that when you can just lift the tray by 2 inches and wrap it in a bit of plastic trim?

I would not be surprised if they were installed straight and the added weight caused the roof to sag. EDIT: It's nearly impossible to predict exactly where the solar panels will line up once installed.

The entire facade is just ridiculous and useless. I assume it's to ape some kind of swank covered parking/loading zone but nothing about that house justifies it. It's something you'd see at a golf club or an actual mansion but it's so high and narrow basically any rain would get past it. I know that's obvious and the house would actually look somehow more dismal the way everything is set up but poo poo. E: gently caress beaten
