Hey steino, I took a crack at updating this mod for 0.15.

The only major change to get this working is adding the gas_flow set of sprites from the storage tank to the stone-waterwell entity.

gas_flow =
{
filename = "base/graphics/entity/pipe/steam.png",
priority = "extra-high",
line_length = 10,
width = 24,
height = 15,
frame_count = 60,
axially_symmetrical = false,
direction_count = 1,
animation_speed = 0.25,
hr_version =
{
filename = "base/graphics/entity/pipe/hr-steam.png",
priority = "extra-high",
line_length = 10,
width = 48,
height = 30,
frame_count = 60,
axially_symmetrical = false,
animation_speed = 0.25,
direction_count = 1
}
}

At least that's all that was necessary to get my copy working.

The amount of water it produces will probably need adjusting as well with the new fluid changes.

Thank you very much for the hint.

I only edited the info.json to quick check, saw the crash and had no time to dive into it so far.

I also changed the refill function to add 10 instead of 1 water per tick.

Thanks, steinio.
