Abstract
The concepts relate to reducing energy loss associated with hot water systems. One example is manifest as a selective hot water isolation device that is configured to be connected in fluid flowing relation with a first water line and a second water line and where the selective hot water isolation device is configured to control water cross-over from the second water line into the first water line based upon water flow through the first water line.
Claims4
A selective hot water isolation device that is configured to be connected in fluid flowing relation with a first water line and a second water line and where the selective hot water isolation device is configured to delay water cross-over from the second water line into the first water line for a defined duration after cessation of water flow through the first water line, and further wherein the defined duration is defined, at least in part, by a relationship between a volume of the selective hot water isolation device and a dimension of a bleed hole within the selective hot water isolation device.
