Quicker Hot Water With a Hot Water Recirculating System
Over-the-water-heater: For this configuration, the pump is located above the water heater, and a check valve is located under the sink furthest away from the hot water heater. The pump pressurizes the hot side of the systems and, through the bypass valve under the sink, it pushes the hot water into the cold water system, creating a hot loop.

Re-circulating hot water without a pump - Charles Buell
Hot water is less dense than cold water, making it more buoyant. In this sense it will float on the cooler water. It will displace cooler water which then sinks—because it is denser. This can become an endless loop driven by the hot water in your water heater. All that is required for this loop
