The thermal pump description says it can pump out lava, but I'm not able to place it on volcanic terrain, is this a bug?
I think there is no lava liquid in this game
I thought it'll pump out slag from there
It just pump a bit more water with more power
No, the thermal pump simply produces power from being on top of lava tiles. That's all. The only way to get slag is to melt scrap using the melter.
