@@SStarlight9614 I would imagine Linus would leave the Home Assistant related stuff in the house if they were to move out. It would be a pain to reset and reconfigure the devices for the next house, and leaving a fulling functional system installed is a massive value add for the sale price

Also by the time linus sells the house most of the stuff will probably be outdated.
Linus is just using the channel at this point to get the manpower to build his dream house and file it as a business expense while making the sponsors pay the labor-costs. That's the real galaxy brain move here xD
Energy companies won't hate this. Steady income from the electric pumps that will constantly be cycling the fluid through the system on top of the energy from the pool heater (that he's still going to need.) :P
@@WhiteG60 At night? And is he making the CNG for his heater on it's own? He is an engergy slave as most others too. Never understood the gas heater in the first place in that house. There should have been a heat pump. That would make the climate unit not needed and in the winter would produce a lot of cooling to chill the computers. This system he is building is getting more complex the more gets added to it. Making it nightmare to maintain at a certain point.
It's hard to even be mad about it at this point because it's so insane that as a viewer, you can't help but want to watch it no matter whether it succeeds or fails. AND, nobody else is insane enough to try it!
As an HVAC engineer and an energy engineer, this is one of the best videos I've seen in awhile. Great application of a heat exchanger. Large data centers use this tech for exchanging heat via a "water-side economizer" (i.e. running the evaporative cooling tower via the condensing water loop) when the chillers are off and the outside air temperature (usually controlled via a wet bulb temp enable setpoint) is favorable. Good stuff.
Why did you need to tell us your an engineer. I swear every engineer starts their sentence with something like, "As an ".." engineer.." its really making you all look like the vegans of workers.
Especially since he’s definitely taking all of the computers and servers with him. “Why do I have a heat exchanger loop that goes from the swimming pool to the empty basement!?”
Linus, I just want to thank you. I showed my wife this video and she thinks that my home improvement ideas are way less crazy now. You are a true hero and have saved my marriage.
I really don’t know what type of women you guys marry, but if she didn’t support me with my ideas that I really burn for I wouldn’t have married her and vice versa! I support my wife’s ideas just the same. Matter of fact, she had watercooling and an RTX card before I had any of those things. Also she has two old inline 6 BMWs which I really love! Her hobby’s are also her horses which I totally support and help her in the stable and we go out riding trails all the time, she on her horse, me on my mountainbike (oh she also bought a specialized after realizing how much fun Bombing trails on two wheels is besides the usual 4 hooves). I couldn’t be happier with my with and I never have picked one that I have to beg for realizing my ideas. I’d rather stay single than being enslaved.
Not sure if you plan to do this, but if you are already planning on cooling the solar panels, you might want to look at heating them during the winter as well with the server rack. This way when it snows, the heat from the cooling loop can melt the snow off the solar panels and continue to give some power.
Being a contractor for Linus must be a surreal experience. I can see the morning meetings in front of my very own eyes "you know he's fucking crazy right, well, boss says he pays well so he gets to do whatever he wants"

@@diablalexfull My family works in electrical. No one is interesting in doing something dope and different because that means things go wrong which eats up time and money and causes stress.
As an engineer, the issue isn't coming up with ideas, it's about making them simple enough that maintenance isn't a pain. If something fails during Canada's cold winter... well, we're going to get a good video!
Not dissimilar to an outdoor furnace which uses glycol in very very cold environments. I’m sure it will be fine. May involve some extra maintenance and that’s it.
This exact words came to mind, man if one of those pumps/valves/seals/sensors goes bad is gonna be a pain to troubleshoot and fix the problem in any reasonable amount of time, also spare parts, he probably need at least 1 of each of those components for spares. There`s also something called diminishing returns, the Solar Panels alone already add so much more complexity, I imagined that this will last for maybe a year, until it breaks once and Linus do a workaround to get it working and will stay that way forever.
You know what’s kind of amazing about this series? Whenever in the future that this house has new owners, if they need to do any repairs or upgrades to its infrastructure or design, they’ll have an entire series of videos that meticulously lays out all the details they’ll need to know. It would also be kind of amazing to give the new owners a flash drive of all the videos, plans, layouts, and other info that the owners and any contractor would need to make changes.

If there's one thing home buyers hate its a bunch of DIY modifications that they have to learn because no company exists that will service them for a reasonable price.

@@mtb8300 agreed. I love what Linus is doing to his house with all the tech upgrades.

Thx for the shout out my bro , technically having underfloor heating incased within a shotcrete pool shell may work , the geographic area , shotcrete mix , reactive soil composition and ground movement all plays a part in the decision process.
@@UnabashedOops If the plumbing has been installed correctly the return pipe x 2 ( midway and deep in the pool will run through the heating coils heating the water.

Volume of water ( A ) Water Flow ( B ) Heat condenser power ( C ) Time to correct temp ( D ) = Happy days. Etc etc.
The heat exchangers also work with air conditioning, you can shut the fan on the condenser off and pump the hot refrigerant to the heat exchanger, heating the pool and making the air conditioning more efficient. You know, just in case you want to add more heating elements to your pool.
from what i understand the gas in the ac condenser is about 60C so you could put a chiller in your PC loop and the ac condenser into your hot water service (tank).
@@ianoconnor1515 not quite. For 410a/HFC On a really hot day you will see anywhere between 380-400 PSI on the liquid line. Around 40 - 44°C. In the condenser coil the refrigerant is going from a saturated vapor to a liquid under force. There’s a product out there to heat pools/water. They are called heat pumps. Just like a normal AC but have a series of reversing valves so the condenser coil can act as the evaporator.
Remember to take account temp gradient of around 10C over fluids and please use a industrial grade pump and maybe double it with auto switching. Install pump after servers for minimum operation pressure for server cooling loop. I do heat recovery systems for work.
I wonder what pool water temperature they are expecting, and what server room temperature he wants. Keeping the server room at 20C or so in the summer is going to be a struggle I think, the radiator won't be able to dump much heat once the air temperature is above 15C.
I was a little concerned about the mixed reviews, but I used it last year and hooked it up again this year and it was great th-cam.com/users/postUgkx-izdrK3eF-HMvjzeBOxToD6Fx-4ulJUh . I couldn't get my 10' Intex pool above 76 degrees the year prior and last year I got it to 90 and had to put ice in it. This worked so well! I have just 1 mat hooked up to a 1,000 GPH Intex pump and it makes a significant reduction in the flow rate coming back into the pool, but that is to be expected with how far the water has to travel through the mat.

Look up heat pump water heaters. They have heat pumps on top of hot water tanks now that very efficiently take heat from a room and use it to heat the water. His hot water heating bill would be next to nothing. I've seen some cases where people were spending like $100 a year to provide all their hot water heating needs.

This is incredible. I think maintenance is going to be the the biggest issue over the years - but man, the exchanging and sharing of heating and cooling here is pretty damn awesome.
That won't be an issue at all. The floor heating systems that they plan on using for it don't need any maintenance for decades and when an electrical part does fail, they can just grab a standard part from some random hardware store.
@@SmartassX1 I think the bigger issue is if one of those hoses ever gets clogged and/or breaks, it's going to be "fun" to either cut through the rebar to get to it, or to push a new sections all the way through.
@@TheGodExperiments with proper, treated distilled water, they won't clog, and they won't break either.

They're surprisingly robust.

This is cool, the principle of it kinda reminds me of the heating/cooling system in Norway's New National Museum, which opened last week and I was an HVAC engineer on. Combining several heating and cooling sources and controling them to achieve a given temperature set point in any given area is quite a job :D If this is going to work properly, Jake's got some work cut out for him to program this. I love the solution here :D Remember to fit a frequenzy regulated pump, so that you can have the system flow regulated, so not to need shunts to regulate the heat running in the system. It seems like your pool contractor is quite old school tho, because using flow heat exchangers is quite common in newer pools connected to heat pumps and server rooms. I was just recently involved in a project where they used server room heat to heat the warm water in an office building and ventilation heating in conjunction with a sea water heat pump to control the heating and cooling in the building. In the winter you can also run the heat from the server room through your roof panels to aid snow melting. Also, to make the system more efficient, a heat pump between the pool and server room, is a good idea. ;)
Well, the temperature control seemed fine when I visited the museum this weekend. But I also got the impression that certain rooms added fragrances to the air, like you can do in some luxury cars, forgot to ask the staff though...
@@cdoex1 Good to hear. It'd better, because we had five levels of testing all the systems for indoor climate control in all areas with and without artificial heat, cold and moisture generation to ensure the art is stored safely. -Quite a fun experience to be a part of. I don't know about the fragrances tho. Did you look for the secret door in the men's room?
I think there are several problems to tackle, that should be considered, for this to work properly. 1)The main issue I see, is the "conflict of interest". The Water to the Hardware should be as cold as possible and the water to the pool should be as hot, as possible. 2)The pool probably isn't always filled 3)the low temperature difference between optimal hardware temperature and desired pool heating makes a direct loop basically useless for the heating part (and the plumbing has to be very thoroughly insulated; which it always should be...) 4)the contoll technology has to be very sophisticated (in this configuration) for this to work, even a bit I think, if you install 1)a buffer storage (a large high one, or even two for different temperature niveaus) you can minimize the controll tasks 2) a water/water heat pump would get rid of problem 1 and 4, but would obviously be very pricy Finally, if you get a buffer storage, you could also connect the floor heating, which is in ideal temperature niveau for the pc cooling as well something like that and some hydraulic switching and you're going to do just fine; but it would be a shame for it not to work efficiently; not worth the hassle at all, if it's not done correctly I hope you do read this, all the best
While dealing with heat pumps is definitely becoming more common in commercial systems, until fairly recently it was typically far more region dependent and anything involving a server room is not too typical in most residential housing. Dealing with server rooms is definitely far more common in the price range that Linus' house occupies but there's only so many pools that can be built for high end homes and almost none in the commercial space where such things would be more common. Unless a pool company operates in an especially affluent area or over an incredibly large area you're not going to find pool companies specializing in high end pool construction. Even then, most high end pools tend to spend their pool budget on things like decor, slides and waterfalls not whole home water cooling. Most pool companies I've encountered operate in a relatively small local area which means most pools they're building are going to be the bare bones basics.
Someday he finds out that water actually takes a lot of heat. Then he needs more hardware to heat the pool. This leads to more videos. And so on. Genius!

TLDR: Watch your cooling loop fluid levels carefully and take whatever action needed quickly. Good luck 👍 This is a fantastic idea, I do have concerns because I’ve been a part of pool building and plumbing since I was 5 years old. If in the future you have issues and you start to notice ‘coolant (or whatever fluid you are going to use in this loop)’ loss; cut your losses on whatever is under the pool and do the same concept on whatever the most accessible side of the pool / deck is. I say this because I’ve seen olympic size pools either sink into or lift out of the ground from leaks that put hydraulic forces under the pool, lifting it up (cracking the deck & expanding the rebar) or slowly hollowing out a void under the pool until it sinks bit by bit (sometimes taking the corner of a house with it on the slow journey) I love this idea though, mad props, hope it works for years to come!

@@bobgraton854 "waste of energy" they are literally using waste energy as the heat source, it doesn't matter if the efficiency is suboptimal, heating the pool is secondary to cooling the equipment.

For those curious, fluid heat exchangers are how nuclear reactors can make ridiculously hot water and steam without putting radiation into the steam used to spin the power generators. The radioactive coolant stays in tubes and they shove them into big boiler tanks to boil that water to steam. Source: been a nuclear systems mechanic for 6 years
thats funny, because as soon as he mentioned the problems of chlorine and gunk my first thought was - hey whatabout a loop like nuclear reactors use? Source: nerd
Dammit I just posted before reading this comment. It is basically the primary and secondary system. Hell a good number of them use canals and large bodies of water as the heat sink.
Great fun video. In Sweden and the rest of Europe there is a great deal of pressure to reuse server heat in multi MW data centers, EcoDataCenter use the heat for local town and making wood pellets!
It is a really cool project indeed Linus. But I've studied this kind of water cooling system for energy efficiency in school (I'm a renewable energy engineer), and my concern is that maybe the energy required to actually move around all that water and the control system (valves, etc.) is actually much more than the energy (heat) that is generated from your mechanical room and your solar panels (these ones don't generate that much heat, I've studied that, and you will lose a ton of heat in the transport of the water). And, to heat so much water like in your pool you need too much energy. So you will end up heating just 1 or 2 degrees in your pool :/ My advice is maybe first to calculate roughly how much heat you're going to generate from solar panels and mechanical room, and then compare it to how much you need to actually heat all that water in your pool. You'll see that you need so much more heat. And that can kind of heat can be achieved (sustainably) with solar heaters for pools. These systems are very reliable and cheap. I suggest you look into these pool solar heaters systems, and maybe implement a heat exchanger there (at the inlet of the solar pool heater). It would be cheaper and surely it would maintain your pool warm :D Sorry for my bad English haha. Greetings from México! If somebody sees this, pls like it so that Linus sees my thought :)
Are you sure that it's cheaper to use that sistem plus air conditioning the server room to protect the computers from overheating? Because that was the point of all this.
@@marcosurresti yep the point was getting any free heating for water pool and protect computers. Even at 1 or 2 point celsius more, pool would be better to swim at.
I agree it is a fun project. But I think you misunderstood the point that his intent is to cool the server stack, not heat the entire pool. Adding minimal heat to the pool or its enclosure in the process of cooling the server stack is just a minor benefit. I would think the pool will also be heated for off-season enjoyment but by an actual heater.
They're basically wanting to use the pool as a giant radiator. I think this could work and use less energy than using an air conditioner to do it, but I think the flow rate and pressure required to keep the watercooling loop working and the flow rate and pressure required to efficiently dissipate heat will be very different and this will create enough loss that no heat makes it to the pool and they're just spreading the heat across the house instead. They need a passive heat exchanger that will let them run the loops independently at different rates and pressures.
As a automation engineering student this project makes me so excited and I'm curious to see how well you're capable to implement your idea in the whole sistem
As automaation engineer from Finland this is gonna be cringe jorney 😅. We have done heat recovery around 30 years. Best idea would have been geothermal heating and cooling (heat pump) and then just dumb all extra heat to the pool. Example. There is risk that those panels from the roof is going to boil and explode if pool dont Want any more heat. There should Always be Flow with those panels. Hope Linus Team find it out. :)
not to mention the cost in materials which will probably reach the end of their life span before they have paid for themselves, how much does it cost to put in a window? ( I do realize the youtube video will probably pay for all this and the pool itself)
@@chrisharris1522 the overall materials are not that expensive. Heat exchanging tubes are like 2€ per 1 meter. Copper tubes are also relatively cheap, around 10€ or so per 1 meter. But the check valves, automatized valves, electronics and the last most expensive thing, the whole work, workers do not work for nothing, they don't live for nothing they need something... 15€/ hour in slovakia and that is one of the cheaper options.. this could potentially end up really quick when they find out what it takes to make this thing working... 🤷 and the last thing, the " snake " under the pool is too short to exchange acceptable ammount of heat, you pouring in to the tube like 80 degrees celsius, while it travels through the pipe befor the pool, it loose some of the energy and incomming water temp will be like 70 degrees but the tube is too short to exchange the rest of the energy, they are not made from copper, basic plastic PVC tubes, plastic is very good insulator but not another. The incomming water from the pool to the system will be like 35 degrees celsius and that's not good.. you need atleast 30 or less.. room temperature is best to avoid condensation as well
@@chrisharris1522 For that they can simply look up hydronics maintenance costs. And as hydronics are used by people, those costs are fine. As Linus himself had said "we don't reinventing the wheel here, this is the same old wheel people already invented".
Considering the size of the pool and the thermal mass it represents, I would just run the computers' heat through the pool 24/7. You will barely even scratch a degrees of difference in the pool water.
This is what I was thinking too. It'd be interesting to see calculations on thermal exchange for this system and relative impact on the pool water. What does the actual math say about this?
I also want to see someone calculate this xd i mean what's the wattage of a standard 24/7 pool heater? The computers are propably at a capacity of like 3 to 10 kilowatts
I'm feeling like eventually since the server room is at the bottom of the loop it will inevitably catastrophically fail in the most Linus way possible and flood the rack.
Agreed. As any plumber will surely attest, there is no way such a large system will actually be totally enclosed and without leaks. I'd say, some sort of catastrophic failure is bound to happen in less than a year.
Disagree, I AM a plumber and dont get why it inevitably would leak? Yes, ofc within 200 years sure, maybe Do it right and the risks are minimum.. Then again, i see some sharkbites* and other meh stuff in the video that make me wonder about the quality in murica/canada
@@MutsFire I used to be a plumber apprentice in Spain a few summers, we did full buildings and the new build warranty is around 10 years. In 48 apartment blocks, we would barely have 1 leak or 2, and that was while going at full speed installing/soldering/etc. Totally agree with you, if well done, unlikely to fail for a very long time.
I thought of this too when he talked about the indoor heating. Not sure if that's worth the even higher added complexity, but definitely worth thinking about it
in-floor systems use "normal" water for heating. he does all this additional work at with the cooling system, so that he still can use dedicated distiled colling fluids for the server. mixing it with the in-floor system would make all this work useless. also in-floor systems work normaly with ~40C° warm water( wich is way too high for cooling the servers), if you bypass the traditional heating system and use a heat excanger for the server and the temp sensors in the rooms ask for additional heat up, your in-floor system would also heat up the cooling water for your servers . the thermal output of this servers isnt enough for heating up the house so you still have to use the "traditional" heating source...
@@georgwarhead2801 40c coolant is probably still fine for the servers, the latent heat capability of water is HUGE afterall, that's still like a 50c temperature differential vs the max component temps you want, i've had a GPU loop which was quite warm to the touch, not burning hot but also uncomfortable to keep your hand on so i'm sure definitely above 40C, maybe around 50C and the highest the GPU ever got was 77C in the peak of summer with radiators that hadn't been cleaned in 12 months lol enough to maintain the max overclock i ever got out of the card 24/7 no sweat (1200MHz on an R9 290 that used to run around 800MHz on air since it would max out to 95C on the stock air cooler).
@@RWoody1995 40c on the hot end vs 40c on the cold end makes a huge difference. You are cooling 1 gpu, he wants to cool a system with several gpus + cpus. Normal cooling loops reach 40c max on the hot side
You already have the server room insulated, just use a heat pump (AC) from the server room into a submerged radiator in the pool. With the differential of hot server room and pool-cooled radiator, it will be the most effective and efficient heat pump ever. Running those giant water loops are going to take quite bit of power and the efficiency of both heating the pool and cooling the server room will be poor.
That's a very cool idea and I'm looking forward to see the final result in action. Just hope it's not getting too cold outside at your region and the waterloop will not freeze inside the pipes
You could probably use coolant instead of water if thats a problem. Cars solved that problem a long time ago. Ethylene Glycol has a much lower freeze point.
There in Vancouver Canada(or at least In that area since that's where the office's are) so it definitely does get cold enough to freeze water but that's what antifreeze coolant is for.
@@cody2930 the problem with coolant is it becomes corrosive and reactive with mixed metals... thats why standard AIO coolers use mostly distilled water.. Linus even mentions it at the beginning of the video
i think it can't freeze unless the water flow stops or the servers etc shut down. the decisive factor is definitely the length of the lines and accordingly a well-adapted flow rate! the question is rather whether the pool temperature actually reaches the desired level as desired or expected. you can calculate it roughly, but the deviation is very high due to the strong fluctuations caused by external influences
As a marine engineer... this baffles my head. You made this way too complicated. All you need is a plate heat exchanger on the outlet of your pool pump. Companies like Alfa Laval make small ones that are not expensive and made from a titanium alloy. Just make sure you have an alternative way of cooling if you stop the pool pump.
But then the pool pump would have to be on all the time, the external radiator is necessary as backup since the primary objective is not heating the pool, but cooling the server. That is a two part loop already, adding the panels and the boiler onto that is certainly possible but its just as easy to make another two part loop. Heat exchangers vs the in floor system probably comes down to cost, the pool floor is not finished, so the only extra work is to lay the pipes + material cost vor some PVC tubing.
FINALLY someone is, like me, thinking about building their own house and running it as effecient as possible! Sadly I don`t have the money to actually let my dream come to live. So I enjoy watching Linus doing all of that for me almost the way I would have tried to do it...
@@filip9564 We have to guess how large the pool is, and how much heat (power) the servers are producing, but let me try. Assuming the pool holds 70m^3 of water and the servers use 2 kW of power continously it would take 40 h to warm the pool up by 1°C.
@@anonb315 That's assuming very idealized conditions where the servers, pool water and plumbing together are an isolated system. In reality of course all of them constantly lose heat to the environment.
You see, using your pool as an AIO is ingenious. A free cooling system for your PC, a personal heater, and a hot tub. This is a truly humongous brain moment
This is what I came here to say. Pumping the water all the way through the concrete seems really inefficient compared to just putting a heat exchanger inline with the filter system or on a separate loop.
These smart house videos have been some of the coolest videos LMG has made. I hope and pray that jake can make a writeup about the parts and meathods of making it all work! Im sure he would take the overtime pay 😂😂
Then once you find out how little heat you are removing from that space, get yourself a heat pump water heater. 2 birds, 1 stone scenario. Heats water you will use year-round and will actively cool the area (when active).
That was honestly my first thought there. Since the main problem I've heard for heat pump water heaters is cooling down the room they're in too much that they don't work as well.
Yup.. while this idea seems like a good idea it's not close to being the most efficient use of excess heat. The hot water heat pumps are the much better option. They are around 7x more efficient than gas and 3.5 times more efficient than straight electric.
@@Bartimayus He has a mini-boiler for the floor heating and a ~50-60 gal tank water heater for domestic water [replace this]. The tank water heater would change to a heat pump (hybrid) option.
This doesn’t give the result expected. I’ve had a small pool (211 ft3) that uses a dedicated 3000 watt heater. During the night it was a able to maintain the temperature and sometimes increase it slightly. With this size of pool, the heat of those few servers will (which is probably far less than 3000 Watt) will not really help. I have also built a solar heater for this pool, that was much more effective.
Kinda genius how much we are helping Linus finance his awesome house and the mods by watching videos on how awesome he is making it in a kinda awesome way too…. Hahaha
I love how they needed a mechanical engineer or a power engineer for all of Linus' zany ideas, they aren't really crazy, they're just more or less what you would expect to see in a large industrial plant.

Great concept, but before doing all this you should do some overall calculations and see if the overall heat output of the room is even enough to make any difference in such a large pool. Love your videos and love how year after year you evolve into crazier and cooler ideas!

@@SStarlight9614 I would imagine Linus would leave the Home Assistant related stuff in the house if they were to move out. It would be a pain to reset and reconfigure the devices for the next house, and leaving a fulling functional system installed is a massive value add for the sale price
@@amdkillaplays If it was a full system all installed by a single company with an easy to use user guide for the whole house then maybe it would add to the sale price, if its a custom job with lots of different brands, set up on something like home assistant I dont think it would add any value, especially becuase the new owners might not care much for iot stuff and if it has all been set up by linus, it might be quite difficult for someone not so tech savvy to make a change or learn how to use it. Also by the time linus sells the house most of the stuff will probably be outdated.

As an HVAC engineer and an energy engineer, this is one of the best videos I've seen in awhile. Great application of a heat exchanger. Large data centers use this tech for exchanging heat via a "water-side economizer" (i.e. running the evaporative cooling tower via the condensing water loop) when the chillers are off and the outside air temperature (usually controlled via a wet bulb temp enable setpoint) is favorable. Good stuff.

Not sure if you plan to do this, but if you are already planning on cooling the solar panels, you might want to look at heating them during the winter as well with the server rack. This way when it snows, the heat from the cooling loop can melt the snow off the solar panels and continue to give some power.

As an engineer, the issue isn't coming up with ideas, it's about making them simple enough that maintenance isn't a pain. If something fails during Canada's cold winter... well, we're going to get a good video!
At least it’s Vancouver. It doesn’t get nearly as cold there.
Not dissimilar to an outdoor furnace which uses glycol in very very cold environments. I’m sure it will be fine. May involve some extra maintenance and that’s it.
This exact words came to mind, man if one of those pumps/valves/seals/sensors goes bad is gonna be a pain to troubleshoot and fix the problem in any reasonable amount of time, also spare parts, he probably need at least 1 of each of those components for spares. There`s also something called diminishing returns, the Solar Panels alone already add so much more complexity, I imagined that this will last for maybe a year, until it breaks once and Linus do a workaround to get it working and will stay that way forever.
Yeah it's turn the valve off and abandon the project. Lol.

You know what’s kind of amazing about this series?

It would also be kind of amazing to give the new owners a flash drive of all the videos, plans, layouts, and other info that the owners and any contractor would need to make changes.

im glad someone like you is out there doing projects like this.
Thx for the shout out my bro , technically having underfloor heating incased within a shotcrete pool shell may work , the geographic area , shotcrete mix , reactive soil composition and ground movement all plays a part in the decision process.
Won’t a lot of the heat go into the ground instead of the pool?
@@UnabashedOops If the plumbing has been installed correctly the return pipe x 2 ( midway and deep in the pool will run through the heating coils heating the water.
Leaving the heat coils under the concrete will heat the concrete but not the water as effectively thus requiring a disproportionate
draw on electrical power to achieve the desired heat.
Volume of water ( A ) Water Flow ( B ) Heat condenser power ( C ) Time to correct temp ( D ) = Happy days. Etc etc.
The heat exchangers also work with air conditioning, you can shut the fan on the condenser off and pump the hot refrigerant to the heat exchanger, heating the pool and making the air conditioning more efficient. You know, just in case you want to add more heating elements to your pool.
Buy a system from the crypto miners. I think they will be selling off a few heat exchangers cheap.
boil the pool during summer.
from what i understand the gas in the ac condenser is about 60C so you could put a chiller in your PC loop and the ac condenser into your hot water service (tank).
Lol wonder if his cost savings go out the window from refilling pool due to rapidly evaporating water
@@ianoconnor1515 not quite. For 410a/HFC On a really hot day you will see anywhere between 380-400 PSI on the liquid line. Around 40 - 44°C. In the condenser coil the refrigerant is going from a saturated vapor to a liquid under force. There’s a product out there to heat pools/water. They are called heat pumps. Just like a normal AC but have a series of reversing valves so the condenser coil can act as the evaporator.
Linus really decided to use a nuclear cooling solution for his server rack.
I like this one
I was about to say... Like, yeah. Very much a nuclear heat exchange system. Just needs a big concrete evaporation tower now.
heat makes water boil makes turbine go brrr
Linus needs a nuclear reactor just to power his server rack.
Well any power generation based on combustion also works like this. Coal, oil, etc
Remember to take account temp gradient of around 10C over fluids and please use a industrial grade pump and maybe double it with auto switching. Install pump after servers for minimum operation pressure for server cooling loop. I do heat recovery systems for work.
@Mingyao Liu Don't let Linus see this comment. He'll get "ideas"
This guy pumps
++++
I wonder what pool water temperature they are expecting, and what server room temperature he wants. Keeping the server room at 20C or so in the summer is going to be a struggle I think, the radiator won't be able to dump much heat once the air temperature is above 15C.
I was a little concerned about the mixed reviews, but I used it last year and hooked it up again this year and it was great th-cam.com/users/postUgkx-izdrK3eF-HMvjzeBOxToD6Fx-4ulJUh . I couldn't get my 10' Intex pool above 76 degrees the year prior and last year I got it to 90 and had to put ice in it. This worked so well! I have just 1 mat hooked up to a 1,000 GPH Intex pump and it makes a significant reduction in the flow rate coming back into the pool, but that is to be expected with how far the water has to travel through the mat.

every person(2) that I've talked to that have that sort of system never use it due to cost.
@@justbob333 the reason why they dont use it is cos it costs them electricity to heat up the pavement, this system uses alredy made heat from the server electricity and reroutes it to the pavement effectively for free
Look up heat pump water heaters. They have heat pumps on top of hot water tanks now that very efficiently take heat from a room and use it to heat the water. His hot water heating bill would be next to nothing. I've seen some cases where people were spending like $100 a year to provide all their hot water heating needs.
best cheap snow melting system called "shovel", just couple of hours and you body heat would melt everything around .... with help of shovel....or ice breaker and salt with sand
It’s becoming such an overengineered house…and I love it 😅
Linus, remember the 1st LTT house and the whole room water cooling: Don’t forget to put filters into your return pipes, as soon as they enter the house, and also before each servers cold water feed, to avoid clogging all cooling blocks again 😄

I hope they dont make the mistake of mixing aluminum and copper again, that is what mainly caused it last time, also no anti-bacterial in the water
@@FishFind3000 not really the only thing that could break in this setup that would be very difficult to fix would be the pipes in the walls in the floor of the pool and it is incredibly incredibly unlikely they would have a failure there in which case you just you know stop using those lines.

@@TheGodExperiments with proper, treated distilled water, they won't clog, and they won't break either.

Technology connections is having a stroke that he’s just invented the heat pump
This is cool, the principle of it kinda reminds me of the heating/cooling system in Norway's New National Museum, which opened last week and I was an HVAC engineer on. Combining several heating and cooling sources and controling them to achieve a given temperature set point in any given area is quite a job :D If this is going to work properly, Jake's got some work cut out for him to program this. I love the solution here :D
Remember to fit a frequenzy regulated pump, so that you can have the system flow regulated, so not to need shunts to regulate the heat running in the system.
It seems like your pool contractor is quite old school tho, because using flow heat exchangers is quite common in newer pools connected to heat pumps and server rooms. I was just recently involved in a project where they used server room heat to heat the warm water in an office building and ventilation heating in conjunction with a sea water heat pump to control the heating and cooling in the building.
In the winter you can also run the heat from the server room through your roof panels to aid snow melting.
Also, to make the system more efficient, a heat pump between the pool and server room, is a good idea. ;)
Well, the temperature control seemed fine when I visited the museum this weekend. But I also got the impression that certain rooms added fragrances to the air, like you can do in some luxury cars, forgot to ask the staff though...
@@cdoex1 Good to hear. It'd better, because we had five levels of testing all the systems for indoor climate control in all areas with and without artificial heat, cold and moisture generation to ensure the art is stored safely.
-Quite a fun experience to be a part of.
I don't know about the fragrances tho. Did you look for the secret door in the men's room?
No, unfortunately I was not aware of that being something to look for.
I think there are several problems to tackle, that should be considered, for this to work properly.
1)The main issue I see, is the "conflict of interest".
The Water to the Hardware should be as cold as possible and the water to the pool should be as hot, as possible.
2)The pool probably isn't always filled
3)the low temperature difference between optimal hardware temperature and desired pool heating makes a direct loop basically useless for the heating part (and the plumbing has to be very thoroughly insulated; which it always should be...)
4)the contoll technology has to be very sophisticated (in this configuration) for this to work, even a bit
I think, if you install 1)a buffer storage (a large high one, or even two for different temperature niveaus) you can minimize the controll tasks
2) a water/water heat pump would get rid of problem 1 and 4, but would obviously be very pricy
Finally, if you get a buffer storage, you could also connect the floor heating, which is in ideal temperature niveau for the pc cooling as well
something like that and some hydraulic switching and you're going to do just fine; but it would be a shame for it not to work efficiently; not worth the hassle at all, if it's not done correctly
I hope you do read this, all the best
While dealing with heat pumps is definitely becoming more common in commercial systems, until fairly recently it was typically far more region dependent and anything involving a server room is not too typical in most residential housing. Dealing with server rooms is definitely far more common in the price range that Linus' house occupies but there's only so many pools that can be built for high end homes and almost none in the commercial space where such things would be more common. Unless a pool company operates in an especially affluent area or over an incredibly large area you're not going to find pool companies specializing in high end pool construction. Even then, most high end pools tend to spend their pool budget on things like decor, slides and waterfalls not whole home water cooling. Most pool companies I've encountered operate in a relatively small local area which means most pools they're building are going to be the bare bones basics.
this has to be the biggest brain moment i have ever seen, why buy a hot tub when you can make one while cooling your rig at the same time

TLDR: Watch your cooling loop fluid levels carefully and take whatever action needed quickly. Good luck 👍
This is a fantastic idea, I do have concerns because I’ve been a part of pool building and plumbing since I was 5 years old. If in the future you have issues and you start to notice ‘coolant (or whatever fluid you are going to use in this loop)’ loss; cut your losses on whatever is under the pool and do the same concept on whatever the most accessible side of the pool / deck is.
I say this because I’ve seen olympic size pools either sink into or lift out of the ground from leaks that put hydraulic forces under the pool, lifting it up (cracking the deck & expanding the rebar) or slowly hollowing out a void under the pool until it sinks bit by bit (sometimes taking the corner of a house with it on the slow journey)
I love this idea though, mad props, hope it works for years to come!
2:30 AND if you ever got a leak, you could drain the entire pool into your server room!
"We don't want to loose thermal energy to the environment around us"
Linus going above and beyond for a suboptimal heatspreader, so yes they told you right
Well on a really hot day you wouldn't want the heat spreader to turn into a heat collector.
Heating the pool walls is a waste of energy. Use it on the pool floor only it will be a lot more efficient.
@@bobgraton854 "waste of energy" implying the runoff heat is being used for literally anything else and not just lost to the air otherwise
@@bobgraton854 "waste of energy" they are literally using waste energy as the heat source, it doesn't matter if the efficiency is suboptimal, heating the pool is secondary to cooling the equipment.
😂 it would be dumb to waste 2000w for 5000w cooling
But hyper efficient water pumps are a tested technology and they probably could run with 200w

@@TimUnknown-h5q He got the idea from someone in discord.
For those curious, fluid heat exchangers are how nuclear reactors can make ridiculously hot water and steam without putting radiation into the steam used to spin the power generators. The radioactive coolant stays in tubes and they shove them into big boiler tanks to boil that water to steam.
Source: been a nuclear systems mechanic for 6 years
be careful, soon Linus may ask you to build a reactor under his house
thats funny, because as soon as he mentioned the problems of chlorine and gunk my first thought was - hey whatabout a loop like nuclear reactors use? Source: nerd
"Yeah but why be safe like that when You can pump radioactive water around for the hell of it?" -Russian engineers
also reminds me of old timy machine guns.
Dammit I just posted before reading this comment. It is basically the primary and secondary system. Hell a good number of them use canals and large bodies of water as the heat sink.
Great fun video. In Sweden and the rest of Europe there is a great deal of pressure to reuse server heat in multi MW data centers, EcoDataCenter use the heat for local town and making wood pellets!
It is a really cool project indeed Linus. But I've studied this kind of water cooling system for energy efficiency in school (I'm a renewable energy engineer), and my concern is that maybe the energy required to actually move around all that water and the control system (valves, etc.) is actually much more than the energy (heat) that is generated from your mechanical room and your solar panels (these ones don't generate that much heat, I've studied that, and you will lose a ton of heat in the transport of the water). And, to heat so much water like in your pool you need too much energy. So you will end up heating just 1 or 2 degrees in your pool :/
My advice is maybe first to calculate roughly how much heat you're going to generate from solar panels and mechanical room, and then compare it to how much you need to actually heat all that water in your pool. You'll see that you need so much more heat. And that can kind of heat can be achieved (sustainably) with solar heaters for pools. These systems are very reliable and cheap.
I suggest you look into these pool solar heaters systems, and maybe implement a heat exchanger there (at the inlet of the solar pool heater). It would be cheaper and surely it would maintain your pool warm :D
Sorry for my bad English haha. Greetings from México!
If somebody sees this, pls like it so that Linus sees my thought :)
Are you sure that it's cheaper to use that sistem plus air conditioning the server room to protect the computers from overheating? Because that was the point of all this.
The point of this system is cooling the server room, not heating the pool.
@@marcosurresti yep the point was getting any free heating for water pool and protect computers. Even at 1 or 2 point celsius more, pool would be better to swim at.
I agree it is a fun project. But I think you misunderstood the point that his intent is to cool the server stack, not heat the entire pool. Adding minimal heat to the pool or its enclosure in the process of cooling the server stack is just a minor benefit. I would think the pool will also be heated for off-season enjoyment but by an actual heater.
They're basically wanting to use the pool as a giant radiator. I think this could work and use less energy than using an air conditioner to do it, but I think the flow rate and pressure required to keep the watercooling loop working and the flow rate and pressure required to efficiently dissipate heat will be very different and this will create enough loss that no heat makes it to the pool and they're just spreading the heat across the house instead. They need a passive heat exchanger that will let them run the loops independently at different rates and pressures.
As a automation engineering student this project makes me so excited and I'm curious to see how well you're capable to implement your idea in the whole sistem
I bet you make some crazy shit on factorio and/or Dyson sphere program, huh?
sistem
As automaation engineer from Finland this is gonna be cringe jorney 😅. We have done heat recovery around 30 years. Best idea would have been geothermal heating and cooling (heat pump) and then just dumb all extra heat to the pool.
Example. There is risk that those panels from the roof is going to boil and explode if pool dont Want any more heat. There should Always be Flow with those panels. Hope Linus Team find it out. :)
@@jarso Do all automation engineers have horrible spelling and grammar? xD .. No jk jk, not a grammar nazi, but I couldn't help myself.

I love jake just sitting at the side of the pool looking overwhelmed when linus is talking about how complicated this is going to be lol
This is a pretty brilliant idea. Every apartment complex with a pool should also have a colocation facility next door to keep the pool warm.
Linus has finally done it. After years of " air cooling is better" and "liquid cooling is better" he's actually using both now
As a software architect, watching them diagram this system I can’t help but think “but the maintenance costs…”
Good luck, Linus!
LTTStore.com
not to mention the cost in materials which will probably reach the end of their life span before they have paid for themselves, how much does it cost to put in a window? ( I do realize the youtube video will probably pay for all this and the pool itself)
@@chrisharris1522 the overall materials are not that expensive. Heat exchanging tubes are like 2€ per 1 meter. Copper tubes are also relatively cheap, around 10€ or so per 1 meter. But the check valves, automatized valves, electronics and the last most expensive thing, the whole work, workers do not work for nothing, they don't live for nothing they need something... 15€/ hour in slovakia and that is one of the cheaper options.. this could potentially end up really quick when they find out what it takes to make this thing working... 🤷 and the last thing, the " snake " under the pool is too short to exchange acceptable ammount of heat, you pouring in to the tube like 80 degrees celsius, while it travels through the pipe befor the pool, it loose some of the energy and incomming water temp will be like 70 degrees but the tube is too short to exchange the rest of the energy, they are not made from copper, basic plastic PVC tubes, plastic is very good insulator but not another. The incomming water from the pool to the system will be like 35 degrees celsius and that's not good.. you need atleast 30 or less.. room temperature is best to avoid condensation as well
@@chrisharris1522 For that they can simply look up hydronics maintenance costs. And as hydronics are used by people, those costs are fine.

From watching what this channel used to be to where Linus is now, good for you man, you are living your dream!
Such a cool concept! I'm excited to see these videos roll out!
Considering the size of the pool and the thermal mass it represents, I would just run the computers' heat through the pool 24/7. You will barely even scratch a degrees of difference in the pool water.
This is what I was thinking too. It'd be interesting to see calculations on thermal exchange for this system and relative impact on the pool water. What does the actual math say about this?
@@shponglefan the math says Linus probably wants server room cool, pool hot is not the main goal.
@@shponglefan im too woozy to do the math, hopefully someone else replies to this comment with actualy calculations

As a pool boy and PC enthusiast, this is by far the most satisfying video you've ever made for me. The recycling of energy is enough to get me!
I'm feeling like eventually since the server room is at the bottom of the loop it will inevitably catastrophically fail in the most Linus way possible and flood the rack.
Agreed.
As any plumber will surely attest, there is no way such a large system will actually be totally enclosed and without leaks.
I'd say, some sort of catastrophic failure is bound to happen in less than a year.
And it will be glorious

Disagree, I AM a plumber and dont get why it inevitably would leak? Yes, ofc within 200 years sure, maybe
Do it right and the risks are minimum..
Then again, i see some sharkbites* and other meh stuff in the video that make me wonder about the quality in murica/canada
@@MutsFire I used to be a plumber apprentice in Spain a few summers, we did full buildings and the new build warranty is around 10 years. In 48 apartment blocks, we would barely have 1 leak or 2, and that was while going at full speed installing/soldering/etc. Totally agree with you, if well done, unlikely to fail for a very long time.
You should ALSO add a connection to the in-floor system so if it's winter you can dump the heat into the floor instead of the radiator outside.
I thought of this too when he talked about the indoor heating. Not sure if that's worth the even higher added complexity, but definitely worth thinking about it
in-floor systems use "normal" water for heating. he does all this additional work at with the cooling system, so that he still can use dedicated distiled colling fluids for the server. mixing it with the in-floor system would make all this work useless. also in-floor systems work normaly with ~40C° warm water( wich is way too high for cooling the servers), if you bypass the traditional heating system and use a heat excanger for the server and the temp sensors in the rooms ask for additional heat up, your in-floor system would also heat up the cooling water for your servers . the thermal output of this servers isnt enough for heating up the house so you still have to use the "traditional" heating source...
A heated pool in the winter is awesome
@@georgwarhead2801 40c coolant is probably still fine for the servers, the latent heat capability of water is HUGE afterall, that's still like a 50c temperature differential vs the max component temps you want, i've had a GPU loop which was quite warm to the touch, not burning hot but also uncomfortable to keep your hand on so i'm sure definitely above 40C, maybe around 50C and the highest the GPU ever got was 77C in the peak of summer with radiators that hadn't been cleaned in 12 months lol enough to maintain the max overclock i ever got out of the card 24/7 no sweat (1200MHz on an R9 290 that used to run around 800MHz on air since it would max out to 95C on the stock air cooler).
@@RWoody1995 40c on the hot end vs 40c on the cold end makes a huge difference. You are cooling 1 gpu, he wants to cool a system with several gpus + cpus. Normal cooling loops reach 40c max on the hot side
All these ideas in this series make me think that Jake eventually will need his brain water-cooled just to keep up with Linus's craziness
0:53
WELL DAMN I MEAN WHEN YOU PUT IT LIKE THAT
You already have the server room insulated, just use a heat pump (AC) from the server room into a submerged radiator in the pool. With the differential of hot server room and pool-cooled radiator, it will be the most effective and efficient heat pump ever.
Running those giant water loops are going to take quite bit of power and the efficiency of both heating the pool and cooling the server room will be poor.
Yeah, I was wondering if they had any reasons behind not using heatpumps.
I think by the time we see a video like this, it's way too late for any good advice.
Literally thought about the same thing
I was amazed too he's not using an air to water heat pump to cool the room and heat the pool.
Agree, heat pump is the way to for sure.
This project makes me so happy lol.

@@TheNerdBird_ you just stole a top comment😂
@@twizl4 Unashamed 😂 💕
That's a very cool idea and I'm looking forward to see the final result in action. Just hope it's not getting too cold outside at your region and the waterloop will not freeze inside the pipes
You could probably use coolant instead of water if thats a problem. Cars solved that problem a long time ago. Ethylene Glycol has a much lower freeze point.
There in Vancouver Canada(or at least In that area since that's where the office's are) so it definitely does get cold enough to freeze water but that's what antifreeze coolant is for.
@@cody2930 the problem with coolant is it becomes corrosive and reactive with mixed metals... thats why standard AIO coolers use mostly distilled water.. Linus even mentions it at the beginning of the video
@@mannys4539 The lines would need to be buried or well insulated, then, but the longer the lines, the greater the risk in the winter.
i think it can't freeze unless the water flow stops or the servers etc shut down. the decisive factor is definitely the length of the lines and accordingly a well-adapted flow rate! the question is rather whether the pool temperature actually reaches the desired level as desired or expected. you can calculate it roughly, but the deviation is very high due to the strong fluctuations caused by external influences
Me: I will sleep early tonight so i'm not late for work
Also me at 3am: Watching linus heat a freakin pool using heat from his servers
As a marine engineer... this baffles my head. You made this way too complicated.
All you need is a plate heat exchanger on the outlet of your pool pump.
Companies like Alfa Laval make small ones that are not expensive and made from a titanium alloy.
Just make sure you have an alternative way of cooling if you stop the pool pump.
dude i always wanted to be a engineer and im looking at this like im not a engineer and i can tell you this is complicated beyond reason.
Right, I hope they are doing more engineering than the doodles on the steel panel.
Would titanium be overkill? 316 stainless steel should be enough?
But then the pool pump would have to be on all the time, the external radiator is necessary as backup since the primary objective is not heating the pool, but cooling the server.
That is a two part loop already, adding the panels and the boiler onto that is certainly possible but its just as easy to make another two part loop.
Heat exchangers vs the in floor system probably comes down to cost, the pool floor is not finished, so the only extra work is to lay the pipes + material cost vor some PVC tubing.
Maybe the pool pump doesn't run continuously??
There are a lot of different ways to manage a pool.
@@petejones6827 It seems kind of simple to me...Also not an engineer.

Same here
No worries. The heat gained in the pool is less than 0,5 degree C. So i doubt it would feel any different. But getting the basement cold. Sure!
@@AntimatePcCustom estimate or guesstimate?
@@filip9564 We have to guess how large the pool is, and how much heat (power) the servers are producing, but let me try. Assuming the pool holds 70m^3 of water and the servers use 2 kW of power continously it would take 40 h to warm the pool up by 1°C.
@@anonb315 That's assuming very idealized conditions where the servers, pool water and plumbing together are an isolated system. In reality of course all of them constantly lose heat to the environment.
06:28 The moment you realize that first Jake, then the Gremlin and then YOU laugh maniacly. xD
You see, using your pool as an AIO is ingenious. A free cooling system for your PC, a personal heater, and a hot tub. This is a truly humongous brain moment

2:23 just grab a marine heat exchanger, they are great for this exact thing. You don't even need them attached to your filter loop.
This is what I came here to say. Pumping the water all the way through the concrete seems really inefficient compared to just putting a heat exchanger inline with the filter system or on a separate loop.

Then once you find out how little heat you are removing from that space, get yourself a heat pump water heater. 2 birds, 1 stone scenario. Heats water you will use year-round and will actively cool the area (when active).
That was honestly my first thought there. Since the main problem I've heard for heat pump water heaters is cooling down the room they're in too much that they don't work as well.
He's already got a water heater in there though for the underfloor heating.
I don’t see this heating a decent sized pool to much, maybe an inflatable Intex a couple degrees but not a 20,000 gallon pool…
Yup.. while this idea seems like a good idea it's not close to being the most efficient use of excess heat. The hot water heat pumps are the much better option. They are around 7x more efficient than gas and 3.5 times more efficient than straight electric.
@@Bartimayus He has a mini-boiler for the floor heating and a ~50-60 gal tank water heater for domestic water [replace this]. The tank water heater would change to a heat pump (hybrid) option.

Every house Linus lives in becomes another attempt at the "Whole Room Water Cooling Project".
8:28 - That's a nice Renault shirt
Ikr
Only Linus would figure out how to make his pool a business write-off...
This doesn’t give the result expected. I’ve had a small pool (211 ft3) that uses a dedicated 3000 watt heater. During the night it was a able to maintain the temperature and sometimes increase it slightly. With this size of pool, the heat of those few servers will (which is probably far less than 3000 Watt) will not really help. I have also built a solar heater for this pool, that was much more effective.
The point of the loop is more to cool the servers not heat the pool. He is also using solar heat and electric if needed.
Kinda genius how much we are helping Linus finance his awesome house and the mods by watching videos on how awesome he is making it in a kinda awesome way too…. Hahaha
