My mother had the instant hot water unit for many years and loved it. When we remodeled our kitchen I talked my husband into putting one in. He did with reluctance, but, once he used it for his coffee in the morning he was hooked. He said why didn't we do this years ago? Now he too can't live without it. We use it for hot cereal, coffee, hot water for cooking vegies poached eggs, jello, literally anything that you would use hot water for and we don't waste water anymore.
