The pipe connections (7,8,11,12) are on two adjoining sides of the radiator and the input and output connections (7,8) on the first side are joined by channel (9). Connections (11,12) are linked by channel (13), or alternatively one of the channels (9,13) can be closed off by plug (14) so when channel (9) and connections (11,12) are closed on the second side, the heating fluid comes in at connection (7) and flows from connection (11) into the pipework (1) and so out through connection (12). The plug (14) can have its own transfer channel (20) closed and opened by a separate plug (21) to flow part of the fluid past the radiator altogether. |
