The water tank 18 and expansion vessel 28 device comprises an auxiliary reservoir 46 which is arranged under the expansion vessel 28, which is connected to the latter by an automatic valve 48 and which comprises a liquid entry endpiece 50 and a liquid exit endpiece 52, which can be connected onto a bypass 62 shortcircuiting a heat exchanger 10. A liquid flowing through the bypass 62 shortcircuiting the heat exchanger 10 can thus be degassed. <IMAGE>
