Even at the highest point of a heating installation system it is possible, in the case of the liquid originating from the boiler, to obtain a nonsaturation state ensuring the absorption of air by subjecting the liquid from the boiler intermittently to a high pressure and at least to atmospheric pressure and by deaerating it during the stage of action of the atmospheric pressure, during which the liquid from the boiler cannot enter the circulation system, the liquid from the boiler being, after the deaeration stage, subjected to the same high negative pressure as the system before being placed in communication with the closed-circuit circulation system. <IMAGE>
