Abstract
A radiator for domestic heating with a heat-transfer fluid operating in two-phase form includes a reservoir of the heat-transfer fluid; a hot source, intended to raise the temperature of the heat-transfer fluid to a temperature such that it causes said fluid to undergo a change of phase; and a heater, at which the heat transfer with ambient air takes place, having n channels, communicating in a lower zone with the reservoir, it being possible for n to be equal to 1. The heat-transfer fluid is a mixture of at least two different heat-transfer liquids, the heat-transfer liquids having between them boiling points differing by at least ten degrees Celsius, and the liquid with the lowest boiling point representing 70% to 95% of the volume of the mixture for a mixture temperature of about 20° C.
