I've just set up my first well, and for some reason it doesn't produce any thermal water (https://imgur.com/RpU8xmn). The well is powered and expected production is 3/sec but nothing is happening. Am I doing something wrong? (The ring of pipes is just to see if there was output anywhere).

When I place the well, the 4 inputs appear which seems strange.

I'm running a LOT of mods including Angels and Bobs, but I haven't encountered any other conflicts, and it would seem odd for something to conflict with geothermal vents as it is entirely new.

Any ideas?

mlmshannon, there is an option for the mod under Options -> Mod Settings -> Startup tab for making Geothermal wells require water input to give an output. I don't know if it's on by default, but by the looks of yours having input feeds, I would say this option is on for you.

Yes! That was exactly the problem, just needed water.
I didn't think to check for mod settings. :/
Thank you.
