Accelerated hot water delivery system

A plumbing system comprising:

• a hot water source;
• conduit means, in fluid communication with said hot water source and at least one plumbing fixture, for enabling circulation of hot water from said hot water source to said plumbing fixture and return to said hot water source;
• pump means for circulating hot water through the conduit means;
• flow switch means for generating a signal in response to water flow in said conduit means;
• control means for causing said pump means to circulate hot water through the conduit means in response to the flow switch means signal and for stopping said pump means, said control means including timing means for causing said control means to stop the pump means after a selected period of time;
• temperature sensor means for generating a signal in response to sensing a selected water temperature in said conduit means, said control means being responsive to said temperature sensor means signal for stopping said pump means;
• said sensor means being disposed along said conduit and adjacent to said plumbing fixture;
• a draw pipe connected between each plumbing fixture and the conduit means and wherein said conduit means comprises a conduit pipe having a substantial larger diameter than said draw pipe;
• one-way valve means, disposed proximate said plumbing fixture, for enabling cold water to pass from a cold water line into said conduit means;
• and
• hot water recovery means for drawing hot water from said conduit means into said hot water source subsequent to withdrawal of hot water from said plumbing fixture, hot water withdrawn from said conduit being replaced by cold water passing through said one-way valve means.
