As to the water from your RO unit being cold, you 'can' run a combination of hot and cold water on the inlet of the ro unit to get your water up to about 80F. IME that is the best way to get rated output of an RO system and is even more effective than running a booster pump. The downside is that you can easily cook your RO membrane and DI unit if you go too much above 110F water and you have a much higher copper and TDS from the water heater than the cold water line.
