ABSTRACT:
In a hot water distribution system, the water oscillation in hot water supply line maintains hot water line in heated condition by ensuring heat transfer from the water heater to a hot water line executing regenerative heat transfer technique. Fulfillment of longitude water oscillations is ensured by installation of at least two flexible elements such as pressure air accumulators, wherein one is connected to water heater reservoir, and another is connected to hot water line in vicinity to most remote hot water fixture.This can be combined with one of pressure air accumulators initiator of water oscillations that is used for initiation and maintaining of the water oscillation. Heat spreads through the hot water line ensuring hot state of water near all fixtures of the line ensuring instantaneous hot water supply at moment of tap opening.
