I recently saw on an episode how they used a heat pump connected to the water heater to heat the water to save energy. I am wondering if there is a reverse process. we live in Arizona and have well water. during the summer we do not have any cold water because the water is heated in the storage tanks on top of our aquifer of water is hot, making it very difficult sometimes. we have to run bath water for our two year old and let it sit until it cools down enough to give her a bath. we are trying to find a solution. please help!!!
