An enclosed fluid-containment vessel (20) for use with a sealed central heating (CH) system and an unvented hot water (HW) system supplied with water from a regulated pressure source (16, 13) is internally divided into two chambers (21, 22) by a single disc-like partition (3) carrying a tube (6) opening into the respective header region of the chambers (21, 22). The single partition (3) is comparatively free to expand and contract within the vessel (20) when subjected to thermal cycling. |
