<p>An apparatus is shown for attachment to a plumbing system for the rapid on-demand delivery of hot water through the plumbing system to an ultimate point of use. The apparatus includes a diverter valve located in a hot water supply line upstream of the point of use. The diverter valve is actuated for a predetermined interval by a user to initially purge cold water from the hot water line to a drain. After the preset interval, the valve automatically closes. The initial diversion of cold water standing in the water supply line causes rapid delivery of hot water to the point of use once the diverter valve has completed its cycle.</p> |
