Abstract

Provided is a method of controlling a supply of heated water from a source including a heating appliance (301) to a plurality of water outlets (302, 303) remote from the heating appliance, the method comprising: detecting a demand for water from a first water outlet (302), identifying the demand as likely to be associated with the first water outlet (302) and setting to a first target water temperature value, associated with the first outlet, a target water temperature for the temperature at which water is supplied; detecting a demand for water from a second water outlet (303), identifying the demand as likely to be associated with the second water outlet, and resetting to a second target water temperature value, associated with the second outlet, the target water temperature at which water is supplied; wherein the demand is associated with an outlet based on a detected flow characteristic. Also provided is a hot-water supply installation having a plurality of controllable outlets, the installation including: a source of hot-water with an outlet having a controllable outflow temperature; a flow measurement device to provide data on water flow between the source and the plurality of controllable outlets; a temperature sensor to detect the outflow temperature; a memory storing parameters linking flow data to outlet identity, and associating each of the plurality of controllable outlets with a respective target temperature; a processor operatively connected to the memory, the flow measurement device, and the first temperature sensor; the processor being configured: in the event that one of the plurality of controllable outlets is opened, to determine based on a detected flow characteristic which of the plurality of controllable outlets has been opened, and then based on that determination to control the outflow temperature of the source, in accordance with stored parameters for the determined one of the controllable outlets; and in the event that another of the plurality of controllable outlets is opened, to determine which another of the plurality of controllable outlets has been opened, and then based on that determination to control the outflow temperature of the source, in accordance with stored parameters for the determined another of the controllable outlets.
