This is a method and means for maintaining a constant supply of a fluid with specific characteristics within a fluid supply conduit from a supply source of the fluid with specific characteristics at a point of service of the fluid with specific characteristics in which a first open end of a recirculation conduit is located within the fluid with specific characteristics supply conduit adjacent the point of service. A second end of the recirculation conduit is connected to pump means in such manner that a portion of the fluid with specific characteristics within the fluid with specific characteristics supply conduit adjacent the point of service is constantly circulated back. In an alternate embodiment a similar recirculation conduit is utilized in a manner to prevent freezing of conduits in a total fluid supply line which includes portions in relatively warm areas and in areas subject to freezing.

The invention claimed is: 1. A method for maintaining instantly available hot water at a hot water point of service comprising: inserting a recirculation conduit within a hot water supply conduit containing hot water and connected to a supply of hot water within an hot water tank in such manner that a first open end of the recirculation conduit is adjacent the point of service and within hot water; connecting a second end of the recirculation conduit to fluid pumping means; and activating said pumping means in a manner which causes constant circulation of hot water from the point of service to the hot water tank. 2. A method for preventing freezing of water in a water conduit circuit comprising: locating a water recirculation conduit within the water conduit extending from a first warm area to a second coldest area of the water circuit; connecting pumping means to said water recirculation conduit; and activating said pumping means so as to create a constant recirculation of water through the recirculation conduit from the first warm area to the second coldest area and from the second coldest area to the first warm area. 3. A method for maintaining instantly available fluid having constantly uniform characteristics at a fluid point of service comprising: inserting a recirculation conduit within a fluid supply conduit containing fluid with specific characteristics and connected to a supply of fluid with said specific characteristics within a supply of fluid with said specific characteristics in such manner that a first open end of the recirculation conduit is adjacent the point of service and within the fluid; connecting a second end of the recirculation conduit to fluid pumping means; and activating said pumping means in a manner which causes constant circulation of fluid with said specific characteristics from the point of service to the supply of fluid with said specific characteristics. 4. Apparatus for maintaining instantly available hot water at a point of serve comprising: recirculation conduit means within a hot water supply conduit leading from an hot water supply tank to a point of hot water service having a first open end adjacent the point of hot water service and a second end connected to fluid pumping means; and means cooperative with said pumping means to convey hot water from said recirculation conduit means to said hot water supply tank.
