I guess it’s cultural. Afaik Americans drink very cold water while Europeans like me are fine with lukewarm water. Pretty sure hot water can be preferred as well.
Also: tea has to be hot, otherwise the water won’t take all the flavors or it would take much longer depending on the tea. You can still drink it when it’s cold and I think some people prefer some kinds of tea cold, or mixed beverages based on tea like ice tea. There is also iced tea which is tea but old, I think it’s common in Japan.
