Hot water underfloor heating collector and distributor box - has two shells welded to partition and internally threaded connectors welded on

摘要

The combined supply distributor and return flow collector (1) for a hot water under floor heating system is the shape of an elongated rectangular box made from steel sheet. It has two compartments (3,4) divided by a partition (2) secured between the out-turned flanges (7,8) of a trough shaped base and top (5,6). These are welded together. Sets of connections for water distributor tubes are formed by internally threaded collars (15,16) secured in openings in the ends and sides. These collars have rings projecting from one end, used for welding in the respective openings.
