A seal (30) for use in an electrically heated vessel comprising a container space for containing liquid and a heating element for supplying heat to the container space is intended to be used at a position inside the vessel for protecting a portion of the vessel which is present at a side of the heating element facing away from the container space from penetration of liquid from the container space. To this end, the seal (30) has an annular shape and comprises at least one resilient circumferential projection (31) extending outwardly. The projection (31) has at least one discontinuity (34) in its surface (35), whereby it is possible to stop scale particles from penetrating between the seal (30) and an inner surface of the vessel, which may otherwise occur and lead to leakage problems. |
