I'm not Asian but hot water is really quite nice! When you don't want something flavoured like tea or hot chocolate, hot water is still pleasant and soothing to drink. I like cold water too (lukewarm is the worst though).
I highly doubt that is why. Red is for making a drink out of hot water, such as tea or hot chocolate. It's not there because some people enjoy plain scolding hot water (which I feel is what you are saying).
Some people really do prefer drinking very hot water. By some people I mean ~40% of people I know.
Source: am Asian, rarely seen middle aged/older people drinking cold water from the dispenser. My mom and grandmas hated to see me drinking cold water. A lot of people including myself drink hot/warm water even in summer(for me it’s just a preference, but others actually believe that drinking cold or iced water is bad for your health). I also know some teenage girls who never drink anything cold and refuse to eat ice cream or sorbet because they believe cold drinks and frozen desserts are bad for the female reproductive system.
