To get instant hot water, you need to have a loop in the piping system that circulates hot water back to the water heater. Water circulating pumps move the hot water through this loop to maintain the temperature. Circulating pumps are often used to circulate hot water so that a faucet will provide hot water instantly upon demand.
Pumps located at the water heater are suitable for installations with a pre-installed hot water return line. Pumps located at a point of use, like under a sink, do not require or use a dedicated hot water return line. A timer and thermostat design maintains hot water in the home's interior plumbing during the time that a timer on the device is set to do so.
Hot water circulating pumps increase heat in the piping system, which in turn increases system pressure. Heat loss through the piping will be greater as a result of the increased heat passing through it. However, thousands of gallons of water a year could be saved by installing a hot water recirculation pump. The pump makes hot water more quickly available everywhere in the home, reducing the wait for hot water and not letting cold water go down the drain while waiting for hot water.
