Abstract: A hot water unit fluid supply control system for a hot water unit is disclosed. The hot water unit has a heating system that is operable in a heating cycle to heat up water in at least a first region of the water unit, and a sensor arrangement for sensing a temperature of water of the hot water unit. The control system comprises a control unit configured to: receive operational data relating to an operation of the heating system; receive temperature data from the sensor arrangement; and allow for a volume of water from the first region to be released from the hot water unit as treated water or usable water based on: the operational data, and the temperature data from the sensor arrangement.

Abstract: A method of detecting and locating a fluid leakage in a fluid pipeline network comprising a plurality of sensors for acquiring acoustic or vibration measurement in an area of the pipeline network. The data, recorded by the sensors, are transformed from a time domain to a frequency domain. A leakage condition is determined by comparing, within a predetermined frequency range, measured frequency values of the data with a predetermined threshold value for a corresponding frequency, computing a sum of the measured frequency values within a predetermined frequency range and associating the sum value with a corresponding sensor of the plurality of sensors. Location of the leakage is identified by determining the sensor closest to the source of the fluid leakage, based on comparing the sum values associated with the plurality of sensors in the area of the pipeline network over a period of time..
