The global Water Circulation market was valued at USD 17.51 billion in 2022 and expected to grow at a CAGR of 10.4% during the forecast period. Water circulation refers to the movement of water through a closed system or circuit, such as in a heating or cooling system, a swimming pool, or a hydroponic plant growing system. The purpose of water circulation is to maintain a consistent and desired temperature or to provide nutrients and oxygen to plants or aquatic life. In a heating or cooling system, water is circulated through a series of pipes and heat exchangers to transfer heat to or from a space. The water is typically heated or cooled by a boiler or chiller, and a pump is used to circulate the water through the system. This allows for efficient and consistent heating or cooling of a building or space.
