Abstract
A central heating product comprises a vessel for plumbing between a boiler (7A) of a central heating system and one or more radiator circuits (7I) of the central heating system. The vessel comprises a boiler flow tapping (4A) at the top of the vessel for flow into the vessel from the boiler (7A), one or more boiler return tappings (2A, 3A) for return flow to the boiler (7A) from the vessel, and radiator tappings (1A,1B,1C,1D) for fluid connection with the one or more radiator circuits (7I). The vessel further comprises means for collecting gas/air for expulsion from the central heating system in the form of a bubble catchment area (5D) that is defined by an upper part of the vessel and provided under the boiler flow tapping (4A).
