Hot water heat recycling

Hot water heat recycling is when hot water that has been used in your home is re-used to heat the water in your home. It works by capturing the heat that is normally lost when you use hot water for things like washing dishes or taking a shower. This captured heat is then stored in a tank, and when new cool water comes into the home, the stored heat is used to warm up the new water. This is one way that people can save energy in their home and make their water bills lower.
