Suggestion 1: We all know about how
COOL the ice can be but its not cool to have it melt or freeze so fast!
Assuming we have a 7/7 water tile which corresponds to approximation of 27 cubic meters (
taken from NW_Kohaku suggestion).
We are stuck with 27,000 kg of water (or 27,000,000g) that cools (or warms up) over surface of 6 m2 (top or bottom of the tile)
Knowing that underground water starts at 10015U the water has to drop 15Urists in temperature or 8.3K
Amount of water in the tile would need to loose 900,590,670 kJ of energy to freeze over...
...sigh i wish i knew physics but if i am not mistaken only Fourier equation revolves around time although i am not sure what to substitute as thickness of a barrier...or just treat the entire layer of water as barrier and wait until temperature under it reaches 1000 Urists?. I, however, still not sure, that such amount of water can freeze so goddamn fast (i will edit my post as soon as i find more proper equation.
Assuming TU equals 72 seconds...i think its possible to give water a counter...
Due to water teleportation the first exposed tile probably gonna freeze first...which would cause problems...Although having outflow sealed would stop the spread of water and consecutive ice walls will follow - this might create a a nice phenomena of: more pressure = more water leaks out before cooling = bigger surrounding area under ice
(think of the water traps that spray goblins with water = directional attacks)
its probably also possible to have freeze counters significantly shorter in tiles with 2/7 water (1/7 can turn into ice floor at leisure - it wont impede water flow) therefore under high pressure water leaves at speeds way above cooling time and reaches 7/7 level in no time. When water reaches certain area, pressure lowers to the point where water cannot contain high wave and collapses forming 1/7 - 6/7 poodles. 2/7 with very low counter would freeze first encapsulating the water within.

Suggestion 2:I would like to see something similar towards water melting as well, although this can be offset by:
Suggestion 3:Warm tiles should really be
WARM No matter how sturdy the creature is but walking, 3 m of rock (that is if we assume that difference between z=levels has same thickness) away from
!!MAGMA!!, barefoot is not a good past time.
Same with water.
I fail to see how rock ceiling can lower the temperature from 1111 C (magma) into measly 42 C (warm rock).
It should be high enough to boil the water at least, or scald dorfs without socks.
