Water and heat waste reduction techniques

摘要

A hardware system that performs new energy- and water-saving, restorative tasks upon use is provided. In some aspects of the invention, energy-saving hot water recapturing techniques are provided. In a preferred embodiment, the system may push hot water back to a water tank, and halt such pushing after capturing all such hot water. In other aspects, specialized energy-saving pipes further assist the system, and a user's behavior may also assist the system in implementing additional energy and water-saving options and settings, including, but not limited to, a “Final Rinse” option and the timing of ending water service.;In still other aspects, a user's ending use of water service a plumbing may also trigger an ending spray of handled parts of those fixtures and, optionally, a soap or antiseptic spray or other secretion. The same technology may be applied to other handles and fixtures, like door handles or elevator buttons.

主权项

1. A system for controlling hot water consumption, comprising:
a hot water service pipe connected to both a point of service and to a hot water tank of a hot water heater; a control subsystem; a button or other sensor configured to aid in generating a lead time, said lead time occuring after input from said button or other sensor and prior to the termination of hot water delivery at said point of service; wherein said lead time is based at least in part on user behavior and calculations by said control subsystem; and wherein the system is configured to use said lead time to deliver, with a water replacement valve a colder fluid into said hot water service pipe to move hot water present in said hot water service pipe.
