: Such a system causes no difficulties, only pluses for quick hot water, and losses can be prevented by good pipe insulation. There is a check valve in the line to prevent cold water backflow.
If a cold water valve would be opened in the summer, would the water end up being luke warm at times due to the recirculation of hot through the cold line?
