A circulating pump works by pumping or circulating liquids, gases or slurries in a loop or closed circuit. Their most common application is circulating water in a hydronic cooling or heating system. Since the materials that they pump move around in closed circuits, they do not expend lot of energy. For example, when water is initially pumped upwards, it circulates around a system and eventually returns to its original position. From this point, a pump only needs enough power to counteract the drag or inertia in pipes to propel the water forward efficiently. This process is repeated over and over again.

 

Since they require little energy to function, circulating pumps designed for homes are small enough to fit alongside plumbing systems.
