A residential water heater is 55 feet of developed pipe run from the farthest bathroom. Using standard practice, which change would most directly reduce the long wait for hot water without adding a recirculation pump?

The wait for hot water is driven by the volume of cooled water that must be cleared; using an appropriately smaller-diameter dedicated hot branch (within code sizing limits) reduces that stored volume and shortens the wait. Oversizing the pipe increases stored volume, lowering the thermostat delays useful temperature, and removing insulation increases heat loss.
