Hello. I live in arguably the part of the United States. During the summer, it is disappointing to have to wash your hands in hot water when it's 122F degrees outside. We're having a home built, and the rental we are staying in had the hot water heater, located inside, turned off when we moved in. When we turned on the hot water, it came out cold. unfortnately, I had to have hot water, so I turned the water heater on. Has anyone heard of a cold water chiller? I'm thinking that I could store a large tank of some kind inside where it's air conditioned and hook it up to the cold water line. Any ideas from anyone other then relocate? Ever heard of any commerical product other than a small water dispenser? Your thoughts would be appreciated.
