Aquatuners - Some Clarification Needed

[bigun]

To start, this is base game, with no DLC.

So I'm objectively approaching the beginning of late-game or late stages of mid-game, depending on your stance on things. 

I have a steel Aquatuner at the top of the map with a steam engine and a gas pump to load the steam rocket engine (I don't know how much longer I'm going to need this as I almost have the hydrogen engine researched - I think anyway... stay with me).  I'm using polluted water cycling through the tuner through the entire colony to try to get heat back into check, while getting a bonus of getting some rocket missions done.

As I'm progressing, I was working on getting some steel made, and the ceramic pipe on the output of the Metal Refinery keeps popping open due to over heating.  So as I'm figuring that out I notice that some of my duplicants are starting to suffer from the "scalding" effect, I look over, and in another room (a few screens over) the temp was approaching ~60C (~140F).

Ok, so something isn't cooling the base.  I check my Aquatuner, and the temp sensor inside of the steam room to make sure the steel Aquatuner doesn't overheat has the tuner turned off (I had it set to 270F or 127C).  Then it hit me - are the Aquatuners just offsetting a much broader issue?  Yeah, I can crank the temp sensor close to the Aquatuner's limit.... then what?  Does the Steam Engine cool things down?  Maybe, but then *IT* overheats.  Again... we're kicking the can down the road.

I haven't tried it, but is a better/longer term solution to the heat issue is to use a water geyser to add fresh water and just pump the steam into space?  Or am I misunderstanding a key principle here with tuners and steam engines?

The way to do a cooling cell is pretty simple:
1. Aquatiner cools whatever you want cooled
2. Steam turbine cools aquatuner

But here it gets a bit tricky:
3. Aquatuner needs to cool steam turbine as well.
4. You may want to make sure liquid does not stay too long in the steam-room bypass pipes. If aquatuner is 100% up, add a 1% downtime via timer.

Here are some screenshots for the "cooling cell" I use, circuit for 1% downtime not included. Cooled areas left and right, not included.
Steam turbine feeds back to power grid.

1.This is an image of an oasis,If the surrounding heat isn't managed, the duplicants will quickly suffer from heatstroke or burns.

2.This is a steam engine and aquatuner module, capable of completely eliminating heat and generating power. In the image, the pipes direct heat away from the base, and they also cover the steam engine to keep it cool.

The aquatuner needs to be made of steel to withstand the heat damage threshold of 325°C.
