Attachment (1) has a hollow body (3) with an inlet (4) and outlet (5) positioned on its lower and upper sides, respectively, for connection to radiator (2). A heating element (14) and a thermoregulator (15) are fitted in body (3). A heat protection relay (16) and a warning device (13) are also mounted. Devices (8 & 11) for the compensation of the expansion of the heat carrier are also connected to body (3).
