<p>1. A method of controlling the flow of a fluid circulating in a central heating system, particularly at the radiators (2) in order to balance their radiation, characterised in that it consists in successively setting up or determining the flow of fluid at all points of the pipework (4) in the system adjacent to the radiators (2) by measuring in a manner known per se the pressure differential between one region and another of a selected nozzle (9) disposed in the pipework at all of said points, and then actuating a throttle (5) adjacent each nozzle (9) until the desired value of fluid flow is obtained.</p> |
