How a Circulating Pump Works | DoItYourself.com

Hot Water Recycling. One of the most common purposes of home use circulating pumps is to eliminate the wait for water to heat once a tap is turned on. In a typical hot water system, hot water is produced by the heater and flows through the pipes and then to the taps. Once the taps are turned off, the hot water in the pipes cools off.

Troubleshooting a Circulator Pump | DoItYourself.com

A boiler's circulator pump is used to remove hot water from the boiler, and then pass it into heating devices such as the radiator or a convection pipe system. The power of the pump is enough to cause the water to travel right back up to the boiler from the pipework. Using a circulation pump is a great way of keeping water traveling throughout the system.

Circulating Water - an overview | ScienceDirect Topics

The process of circulating water through tubes embedded in a LCG is referred to as 'convective cooling' (Burton and Collier, 1964; Flouris and Cheung, 2006), and also as 'conductive cooling' (Nunneley, 1970; Xu et al., 1999). Figure 12.1 shows the heat-exchange processes that may take place in a water-perfusion garment (WPG) or in a liquid-cooling garment (LCG).
