A B S T R A C T An unsaturated, air-absorbing condition of boiler- liquid may be reached, even at the highest point in a heating system, in that the boiler-liquid is placed intermittently under high pressure and alternately at least below atmospheric pressure and is de-aerated during the lower pressure phase, while no boiler water enters the circulating system. The boiler water is raised to the high pressure of the system, after the de-aerating phase, before being connected to the circulating system.
