A+ for putting the reference shots up front. SUPER helpful.

I remember when I first started playing oni and was super intimidated by them. Definitely a good tutorial for newer players, even more seasoned can learn new things too.

You can't make a perfect tutorial in 12 seconds. Echo: hold my teacup

I have nearly 1000 hours and you’ve solved a mystery for me. I leave my aqua tuner on during filling. This means I get a 50-50 cooling as an extra blob always hits the bypass bridge.

If you have enough of the liquid available that you use as coolant, you can instead of the buffer tank have one cooling loop if you use a liquid reservoir and put the liquid pipe thermosensor right after it in the loop. That way, you can have the aquatuner run when the reservoir contents is too hot. The 14-degree cooler blobs will flow into the reservoir first and equalize with the rest of its contents. You can then set the thermosensor to any temperature (that the liquid supports) you like to have the room cooled at exactly.

I struggled to get my head around the liquid bypass but thank you very much for explaining it just waiting the holidays to play ONI.

I finally managed to do this! Thank you! Thank you! Thank you! Don't think I'd ever have gotten this far without your help!

Tell me a nerd without telling me you're a nerd: "Wait, that was 27 minutes?? Another, another!" :'D For real though, the aquatuner is such a game changer. It opens up so many possibilities, the late game would be almost impossible without it. This was such a thorough tutorial, but that's a good thing when it comes to such a critical piece of equipment. A+, and thank you.

Freaking crap where have you and this video been the last 300 hours. So much help! Thank you!!!

I do really like your tutorials. Frankly I just like how you go through things. Chill and focused, great combo. Ps easier content, between series?

The term transferring chill is absolutely killing me. The laws of thermodynamics say hot travels to cold always. You have heat transfer. Always heat transfer. End rant, thanks, great vid 👍

Loved it, I really enjoy your tutorials, because we can apply those to different seeds! Keep up the great work!

I honest watched a lot of videos of oni, I’m always exploring new builds and lots more. There’s always something new and something undiscovered. This is by far one of the best video and explanation I’ve seen. Please don’t stop ! Best of luck and I hope to see more

Brilliant videos bro! Without these I dont know if I would ever have broken into mid game. Thanks!

I'm so glad I found this gem of a channel. So much useful information, and the challenge videos are also pretty cool

I watched all your tutorial in 1 month and i can say one thing " THANK YOU" you really saved most of my problems and confusion that i had.

Fantastic format for this video! Thank you for placing the schematics in the beginning!

This is SO helpful! Thanks very much for this!

About the bridge issue: The intake of the bridge, the box with the arrow, acts like a IF-THEN-ELSE decider. Its not a crossing (anymore). If you just connect pipes to different directions, the stuff will be split up. But if you have "an arrow box", then its like FIRST go inside whatever the box directing the stuff to go to and only if its not possible, go the other way (if possible). It took me a while to understand that. (Kudos to ERG for the always amazing content.)

Gotta love that Thermo aquatuner. So many uses... Nice video!

youre my favorite ONI explainer. thanks for your videos!

27:11 don't you dare say sorry, it was a very entertaining tutorial.

Wow thanks for this. Seeing it all in steps like that really helped.

This has been very helpful! I forgot about the liquid bridging - such a good tip

I watched more than 15 seconds but you still got a like. I love the cute little notes you put in there. 😀

Thank you for the clear and detailed explanation, this helped a lot. I'm a lot more confident now that I can pull of this build on my own

Omg this tutorial is GOD TIER, it shows hot he started the aquatuner setup, and explained everything perfectly, love it

Thank you Thank you A lot of videos assume players know the trick and how game mechanic works. Yours are the first one I found that explain why mixing polluted water and water together.

Umm... whoever designed the fluid mechanics of this game, should be introduced to 3 way valves and proper temperature control loop designs. Instead we have the magic liquid bridge and its bugging mechanic became the missing feature of the 3 way valve. Great :)

Awesome tutorial! Thanks a bunch! :)

In simple terms, Aquatuner moves heat Steam turbine destroys the heat and makes power(less than the aquatuner tho) So we use aqua to move heat to the turbine

Very good guide, thank you for your work. :)

Insanly good content. Thank you good sir!

Thanks! The exact tutorial I needed!

Beaultiful tutorial, thank you so much!

Adding comment because the first 15 seconds was helpful - have a great day!

This helped a lot, thanks!

I would avoid using polluted water in the tuner room. When it turns to steam, polluted water leaves a little dirt, and if that gets hot enough, it will turn into a solid block which can short circuit your cooling. If you have some oil or petroleum I think that will work fine with water.

Exceptionally helpful. I just built a Rodriguez in my base, but the water temp is over 100, so while my dupes can breathe again my plants can't. There was some poor planning when sweeping out materials from the surrounding biomes. This will certainly help with that and with keeping the temp down to begin with. Now to farm some shiny Dreks to get the plastic necessary to build the turbine. Fortunately, you have another amazing tutorial about that too! Thanks!

Great stuff. Cheers

Very well done! BUUUUUUT getting super coolant is another monster lol

Don't be sorry for talking that long... trust me it helps people understand wtf to do when utilizing these things. I've been stuck at this mid-game point forever trying to understand exactly how to get the right flow going to get this up and running and I finally get it. Thank you

Great tutorial! - pro tip with 2 liquids instead of vacuuming the room - very space efficient setup - material usage explanation... nice! Also, I thought that bridge is a mistake, but after some playing around it turns out you NEED to have different length bypass vs aqua tuner path. The reason - The aqua tuner can store 10kg of water and while disabled, it doesn't process the water. So as soon as a warm packet of liquid starts traveling towards the sensor, the aqua tuner turns on and starts processing the liquid inside it. That detail makes the whole liquid packet logic a bit confusing, but .ong story short - it works!

Love it!

Awesome explanation! Found your video randomly.

Thank you! I'm, for the first time ever, over five hundred cycles and these things intimidate me lol. I'm going to do it though. I'm making it to space soon.

I use lead conductive wire to act as a fuse. If the lead wire melts, the aquatuner is already overheating.

This info was so juicy I need an thermo for myself.

Simple and cool

thank you

Aquatuners are so messy but so worth it

Amazing video about these handy things, Sadly my dupes are already dying left and right before I could build these

This video was the most didactic video about aquatuners that I have ever seen

Checking in.

tnx!

It will be better if you put your liquid bridge below the aqua tuner inside the insulated tiles . It will pick up less heat from the steam box . And do make it out of some insulated material will help too.

Learning this game is really hard. All my systems break and fail lol. I'm trying to get into the correct frame of mind to make sure I follow all the logical requirements instead of just trying to memorize the builds.

Sleet wheat farm - I'm not using an AT/turbine to cool mine, although I might switch to that in the future. Instead it's cooled by the output from a cool salt slush geyser, run through a small tepidizer to go up to 2C, desalinated, and then feeds into the sleet wheat farm. In the future overflow will go to the bristle berry farm just beneath, that pipe will be warmed just a bit more for the bristle berries. The sand I get from crushing the salt goes to my cool slush geyser's offgassing chamber where I make cold oxygen and clay for ceramics. I will add a grubfruit farm when I can to make mixed berry pie, one sulfur geyser is more than enough and I got two of those.

With the Spaced Out DLC, my current starting planetoid is rich in metal, arbor trees, and pockets of ethanol. The clean water pockets are limited so clean water is kind of scarce, and there's only a few pockets of polluted water near the initial starting biome. There are no reed fibers, or oil on this planet either. So I'm currently without my atmosuits. I can however ranch dreckos for their coats to make my fibers but I need the cool water to produce oxygen. Power isn't a major issue, but oxygen is. There is however a cool steam vent that isn't too far from my starting base with a big pocket of water, however it was about 165 - 175 degrees in F while dormant. The cool steam vent puts out at about 195 - 205 degrees F, not quite hot enough to boil the water. After analyzing it, I built a set of mesh tiles off to the right of the geyser so that the water it generates can flow down. Then I built a chamber with a set of flood gates to bring about 6 tiles worth of water 2 high by 3 wide into it feeding into another flood gate. This chamber is 12 tiles 2 high by 6 wide. And these two are the lower half of the entire chamber. Above the first chamber right after the pool of water from the cool steam vent I have another room that is the same size as the first chamber and this room becomes sealed off with air locks, and the last chamber is open with mesh tiles for my dupes to walk across and build or adjust things if needed. Yes without my atmosuits they suffered scalding and a few of them even got heat strokes in the initial build. The reason I had the separate room above the first flood gate and and the second chamber being opened is that I had to put gas pumps in there to create a vacuum to suck out all of that hot air (oxygen-co2)... so that it wouldn't add heat back into the water. I had the pump as far as possible from the main pool. I only have copper, iron and aluminum to work with. Now to cool this water. I have the aquatuner but I don't have the steam engine as I have not done any material science yet. I need the cool water now because the amount of algae is very low and I was using up the slime fast to turn it into algae. So I didn't have time to do the material science. So how did I cool this water? I used two aquatuners in series one right after another being cooled by 32 - 40 degree ethanol. Just to the right of this tamed steam vent and the chambers I built and up above were two pools of ethanol one right above the other. So I build a big tank chamber to catch all of this ethanol by gravity. I then pumped the water from the cooler chamber which was about 165 about 2 degrees below the pumps capacity before being damaged into the two aquatuners. Then I used radiant pipes going through the cold ethanol into a storage tank. I was also pumping out this ethanol into another building into another storage tank that's feeding two petroleum burners with a carbon skimmer and water sieve setup. Now as for the chilled water in the tank I was sending this out and splitting it two ways. The first was going through a long series of conduction panels under the two chambers within the insulated tiles (igneous rock) and them coming back around still through another series of conduction panels just below the first through insulted tiles (granite) and this feeds back into the aquatuners. The other split of the water is feeding into an electrolyzer build (self powering once running) to give me oxygen. I'm not using any automation on my aquatuners as I didn't have the room for it. However, the water feeding my electrolyzer is about a stable 68 degrees, and Now, this isn't a "permanent" set up and it won't last forever since the heat of the aquatuners and my usage of the radiant pipes is heating up the ethanol near the tuners to about 100 degrees in about 100 cycles, the other side of the ethanol reservoir is about 55-70 degrees. It won't stay cool long and I'm burning so my current use of the acquatuners won't last long, but this was needed for that desperate oxygen. Yeah try doing a build with limited resources and not all technologies unlocked where an aquatuner is a must. This was a challenge. I have 12 dupes, I'm at cycle 224 and finally got enough oxygen to fill the place, but it won't last, but should give me enough time to get some other needed things done. I do have another way to cool the hot water once I break into it and analyze it. There is a cool salt geyser in a cold biome. Not sure if it's producing salt water or brine, but I can pump that and the hot water directly into the same reservoir together then extract the salt out of it. Yeah, it's been a fun build and I really like this colony. I think they'll strive once I can get a few more things automated. Oh and they're still currently living off of meal lice... but I should now be able to get my arbor tree farm - power production going, and I should be able to start to set up some ranches along with getting my material science started. Yeah trying to do an aquatuner build without steam engines and gold is a challenge. I can already transport to the second planetoid through the teleporter, but I want this colony to be "stable" before I send anyone over. I need to get my farms and ranches up and running and I need to get my bathrooms and kitchen(s) built. So yeah, the aquatuners are fun to work with, but can definitely be a nuisance with their heat output. I'd say that my current starting planetoid is about 60-70% dug out already. I have about 3 or 4 isolated cold biomes that I haven't tapped into yet, I haven't broken through the top section but I can see space on the far top left corner and I'm dug down to the lava zone on the bottom right corner. Other colonies, I would have had my farms and ranches up and running at around cycle 50-100... Oh and I had to analyze a tame - close off 2 minor volcanoes too before they started to spill out magma. I love this game!!! ... Now as for the author of this video, your content, tips and explanations of how to build and use them is really good advice to build off of.

Another good way to cool one of these is to use the polluted water from the bathrooms and send the hot Pwater into a peppernut farm. Or just skip the middleman and stick the aquatuner in the peppernut farm directly. Putting it in a bath of ethanol at the bottom of the farm works good because it will spread the heat much better than air when it evaporates. Also, putting a thermo sensor in the chill reservoir like a block of ethanol or brine surrounded by the ice. It makes piping a little simpler and does the same thing. One last thing, using a flow valve at max flow will allow you to make an uninterruptable loop for the aquatuner. I generally stick it outside the steam chamber to save steel, but as long as both input and output pathways are made the same length, it doesn't matter.

I'm sure I'm not the first to point it out, but a lot of mystery would be cleared up if people remembered that "chill" is just a lack of heat. -273C is 0 Kelvin. Supercoolant cannot freeze because there is no more heat left in the fluid for the aquatuner to remove. Heat capacity is the amount of heat required to change a material's temperature. The aquatuner reduces temperature by 14 degrees, which is a different amount of heat depending on the working fluid's heat capacity. Heat is a measurement of energy. Temperature is a measurement of potential the energey - heat - moves from high to low potential - temperature. Temperature does not move, and temperature is not conducted. Heat does.

I just put a buffer gate on the aquatuner thermo sensor and set it to 0.5s. This way, the liquid pack currently in the tuner input pipe segment has moved on, but the one in the thermo sensor is just moving in. Also, for loops with nuclear waste, always put a valve after the sensor (buffer gate applies here too) and put the automation in it. Otherwise, if the tuner turns off with nuclear waste inside, you'll get "corrosive element damage" and lose said coolant to the environment.

Great to see how to set one up. I always have to redo it because it doesn’t work right the first time

there was at one point a long time ago an exploit with ethanol instead of water, and no turbine. the system worked based on the difference in heat capacity of the gas and liquid versions of ethanol. i don't know if it still works or not. i saw it being used once on a livestream of the asteroid oassis. also, one could place an aquatuner near space if they don't have plastic for the turbine. have a water line drip some of the water from a geyser as sacrifice.

i started to paly this game about a month ago I know every thing u are saying here yet I stayed, I loved the way your video is short and on point

You made the best video on aquatuner mate! I'm having a problem tho.. my loop stopped.. do you know why? And what I could do to fix it?

I think I’m too dumb to every think of setting this up, I really appreciate the steps nonetheless

I been looking at your tutorials and they are the best I found. I am personally having a hard time with water purification if you decide to make a tutorial about that.

Can you do a general temperature management tutorial? Particularly in the early to mid game?

thank you to stephanie wisheropp for bullying echo into making more tutorials.

Thanks for the great tutorial! One question though: I built the aquatuner setup just as shown, but the liquid bridge bypass doesn't work. If the liquid gets too cold, the loop just stops. Any ideas why that's the case? Thanks again!

With all of my appreciation of sharing this knowledge, what i do not really like is that those lessons are made in debug mode. The problem with metal refineries in real game is that you are always limited in ore, meaning you are not able to use it most of the time, meaning it would not be that hot enough, meaning you will have not enough energy to run aquatuner constantly, and its own heat is not enough to produce energy... So what you really have to have is the source of EXTREME heat like magma volcano, or source of gas like hydrogen or nature gas vent to be able to produce constant amount energy (pretty limited with gas vents by the way) as an alternative solar panels can be used as well. The rest of other things are pretty limited and resource consumable.

How do you send the liquid back through the aquatuner if it's not cold enough? Do I need to set up a second thermal sensor with a liquid shutoff?

i watched the whole video cuz im a rebel.

I don't like using polluted water in my steam rooms, polluted water has a evaporation point much higher than regular water, which means while you're busy getting the room up to temperature the polluted water has an opportunity to emit polluted oxygen which is lighter than steam and interferes with the function of the turbine. I'd use brine or saltwater instead.

Where/how to i tap off the cooled liqud to cool down a room ? I cant figure out how to tap off the cooled liquid, loop into a room, and then put the liquid back into the system. 😅

I think one dtu is roughly equal to one joule, although I may be wrong.

Every video showing this uses doors and vacuum pressure are there ways to do this without that?

I appreciated this tutorial very much! As a player who takes his sweet time to enjoy watching the progression, I stopped playing ONI couple years back because I could not prevent a heat death. ONI is a game about stressing to survive, true, but this inevitable doom put me off the game entirely - hoping to change that. I'm still worried about heat and slime-lung (Not sure how far I need to progress to get materials for a viable Aquatuner setup to cool my colony). Not sure if I need to go through (or into) slime biome for viable materials, but never figured out how to decontaminate it (haven't played since they added suits, is that what people are using for it nowadays?)

I'm frequently hearing about the "chill" but actually its always the heat moving around :) You're pulling heat out of something and not injecting "chill".

Very nice tutorial! Is there a special reason to cool water into ice and have the chill transferred to metal tiles instead of looping the coolant through the metal tiles directly and skip the two water/ice tiles? Is the high heat capacity of the ice important to keep the temperature stable?

oh my god...... my gameplay has always stopped at steel production bc i cant keep my freaking smelteries cool enough!! ive been using wheeseworts, ice, radiant pipes and thermonullifiers so far but my pipes always crack and it isnt efficient enough. my god.... i have been blind. i didnt know you could keep the water moving with water bridges like that!!! i didnt realize they could be used like that!! oh my god! this is the new industrial age of my oni gameplay!! maybe i can finally build a rocket after years of on and off playing :D

relly didentt need tis video but grait stuff

In the past I had the dirt leftover from the polluted water solidify into a tile, which breaks it. I guess the mistake was both to much polluted water and to high temperature? It can probably only form the tile with enough kilos of dirt?

Hello, I follow this setup but I don't know why but my water is just not hot enough for the steam vent not sure what i am doing wrong

I was wondering why my aquatuner kept breaking I use gold for it and not steel thinking it'll be sufficuent

ONI is the game smart people play to torture themselves. If you aren’t an engineer the only way to have fun is to accept the inevitability of failure and laugh about it. Anyways I have about 100 hours clocked in and I’m still trying to get to space travel.

I did the polluted water and normal water stack and it worked great until the polluted water made dirt which then turned to solid sand breaking the whole thing

so i am playing in creative mode or sandbox mode just to play and learn the things. i literally followed this exactly but the tuner will not heat up thus not heating the water which wont make steam. the tuner wont even over heat either. please advise

Cooling resin to make a solid, hmm sounds like someones doing hash production in oni

I always had a hard time getting my head around temp management until I looked at it the opposite way to everyone else, once I saw that you are just moving heat it made more sense to me, instead of injecting chill, I am moving heat out of the water, through the aquatuner which is moving the heat into the steam room and the steam turbine then deletes it... maybe I am just strange... My mum always said I was backwards

after 2 1/2 years I finally know wha DTU is OMG hahahahhha

Hi, does anyone know why after building it according to the video the output vent of the Aquatuner seems to break sometimes due to cold damage?

Off topic, but why not cool the metal tiles directly instead of making the ice tiles?

If I'm understanding correctly the choice to use a layer of pwater below the water was so you wouldn't need so much of either since ONI forces them to stack? But does the pwater turn into steam or does it stay there after the water does? If it stays, wouldn't it off-gas? If it turns into steam is it psteam? Why is this perplexing me lol. One other question, why do your designs vary from just 2 tiles high for the steam chamber to much larger?

It was tough to like this video, since it had 222 likes. But I did it! 🙃

Is there a way to run aquatuner without steam turbine, before material study terminal?

My ceramic insulated pipes broke like -10c water and 89c enviroment in the steam room what should I do?

I'm having the issue where my insulated pipe that is connected directly to the aquatuner output, is getting damaged no matter what I make it out of. Any tips?

It's a heat pump... No heat created or deleted. It pumps heat from one place to another place. Heat pump 😉.
