Abstract (en)
A procedure for improving the efficiency of a heating system, the heating system comprising one or several heater elements (7) inside which, in an enclosed space (2,5,6), is circulated a heat transfer fluid of which the pressure increases exponentially with increasing temperature. The object of the invention is to improve the efficiency of the heating system. This is carried out in the invention in that the temperature and pressure of the heat transfer fluid contained in the heater element (7) are varied by switching the heating of the heat transfer fluid alternatingly on and off.
