Abstract
The instant invention provides for a kit and method of raising inlet temperature of a water supply by utilizing thermodynamic properties associated with difference in temperatures across a gradient and friction. In particular a portion of an inlet supply pipe is disposed in a sewer line such that the opposing flow of waste water and related material interacts with the inlet piping by increasing the temperature thereof.
Claims7
A device for preheating an inlet of a hot water supply comprising,
- a first conduit sized and shaped to bypass or replace a portion of a sewer pipe, including a toilet flushing line upstream thereof, whereby said conduit has at least one wall defining an interior that directs sewage across an interior base thereof;
- a second conduit disposed within said first conduit traversing across a portion of said interior base, whereby said second conduit is capable of receiving an inlet water supply and preheating same prior to directing the supply to a heating source, whereby the placement of said second conduit does not increase a clogging potential in said sewer pipe and does not require cleaning due to said toilet flushing line;
- and,
- an inlet port and outlet port formed through wall of said first conduit that allows the inlet water supply to be received and directed by the second conduit.
