I've followed like six tutorials and for some reason, it just is not turning on. I've tried building in creative mode, and there just is no luck. I've:

- added the four solar panels to the top
- left the top open
- switched the pumps to pull (they won't enter the valves though)
- made it both 18 blocks tall (and 4 blocks tall)

I just have no clue what I'm doing wrong. The picture below has it extended into the ground just to hide it. This one is in my creative world cause I'm just troubleshooting.

I made one that was six blocks high. Temperature went up to 304K, fine. I then put a resistive heater next to it, powered it, temperature still 304K. Changed the amount of power used at best to 1kRF, but the temperature in the TEP stayed at 304K even after I had waited for the heater to heat up. Tried changing the placement of the heater and using the conductive things, nothing. Had an extreme reactors reactor, so power generation wasn't a problem. I also changed the TEP's controller's position to be as high as possible, nothing changed.

Plenty of water in the plant too.

Only thing that made a difference in brine generation was the height of the plant, with generation being 0.06mb/t at 3 blocks high and going up by 0.02mb/t per every layer added.

I'm playing in 1.12.2, no particular modpack.

Playing on ATM 9 TTS and using it to produce brine but i feel like it's not enough, how to max the output of this thing?

How does this even work? I've increased the height of it, which according to the wiki should increase the max temperature. But I have 2 plants next to each other, with different heights, and they're at max temperature, and it's the same for both of them. 3.02k degrees C.

The controller is detecting the extra height, but the max temperature isn't rising. The wiki also mentions a "multiplier" but I can't see it anywhere. I'm in a canyon from biomes o plenty if that makes a difference.

I'm heating them up with resistive heaters attached to the valves, because it seems to be the only way to keep production going at night and making solar panels is expensive. But I was having the same problem with solar panels attached.

What temperature do I need to produce enough brine/lithium to keep a fusion reactor running? And how many evaporation plants?

I just built the simple one for my first time and while trying to figure out how to use it found out that you can make an advanced one, but honestly it'd take an incredibly large amount of time for me to move it and set it up on the surface, so can you build the advanced Evaporation plant underground?
