In a bid to cool people, not rooms, engineers made a printable fabric that turns body motion into electrical signals that switch on cooling and heating when you need it.
Remember water which isn’t sterile (and manipulated in a glove box under sterile circumstances) accumulates mold, bacteria, assorted nasty protists etc.
Depends on what you do with it, but yeah. Got an aquarium so aware of some of the things water can like doing if neglected. But for a bucket cooling reservoir you could also just add chemicals to keep it clean enough or replace it periodically.
