<p>A central heating installation using radiation through which flows a heating medium, circulates the medium at periodic repeated intervals, the time period of the circulation interval depending upon the temperature in the place or places to be heated, with respect to a desired temperature. The time periods of circulation, at a temperature equal to the desired temperature, are an average equal to a half period, and are longer or shorter for temperature difference below or above the desired temperature. The system has a generator which activates periodically a device which controls the circulation of the heating medium, and which itself is controlled by elements sensitive to temperature.</p> |
