ABSTRACT:
A water circulation unit (120) for reducing bacteria growth in a water supply system includes elements for controlling temperature and flow (133) which is arranged to provide a dynamically controlled flow of water from both a hot water pipe (140) and a cold water pipe (150) to at least one return water pipe (160) such that the water from the hot water pipe is above the temperature region in which dangerous bacteria growth may occur, and the water from the cold water pipe (150).
