A fluid network exchange system for efficiently exchanging fluid in a fluid network for prevention of hygiene risks. The system includes a source and a plurality of sinks. The system also includes flow meters for determining the flow rate at each of the sinks and automatic flushing devices for flushing fluid at each of the sinks. The system determines an order and a flushing time for the plurality of sinks to be flushed. The sinks are flushed starting with the sink with the highest flow rate and ending with the sink with the lowest flow rate. Flushing times are determined based on the length of different pathways corresponding to different sinks.

A heat exchanger that includes a portion for heat exchange with gray water, a portion for heat exchange with clean water, the heat exchanger being arranged to transfer heat between the gray water heat-exchange portion and the clean water heat-exchange portion during a distribution of water and thereby heat a feedwater to a first temperature, wherein the heat exchanger includes a first heating means arranged to achieve the heating of the feedwater, for heating the feedwater to a second temperature, and wherein the heat exchanger includes a second heating means arranged to keep the clean water heat-exchange portion at a temperature greater than or equal to the first temperature during a period without water distribution.

The present invention provides a method for measuring one or more parameters in a water flow in a device intended for recycling of water, said method including directing part of the water flow to a liquid-stagnant space where the measuring is performed. The present invention is also directed to a device intended for recycling of water, said device including a flow path for recycled water, a fresh water inlet, a recirculation water inlet and a recirculation water outlet, a user outlet, a heater and a filter, and wherein the device also includes an off-line bypass loop arrangement which includes a liquid-stagnant space and which off-line bypass loop arrangement also includes one or more sensors enabling measuring in the off-line bypass loop arrangement.

Device for recovering thermal energy from a flow of wastewater from a basin includes a plate heat exchanger traversed by two separate fluid flows and a bypass conduit providing a hydraulic connection. A first inlet of the heat exchanger is placed in a fluid communication with the wastewater outflow opening of the basin to provide a first flow passing through the heat exchanger between the first inlet and a first outlet of the heat exchanger connected to the sewer. A second inlet of the heat exchanger is placed in a fluid communication with a clean water conduit under a water supply network pressure to provide a second flow passing through the heat exchanger without mixing with the first flow, and between the second inlet and a second outlet of the heat exchanger. The bypass conduit provides a bypass between the first inlet of the heat exchanger and the sewer.
