Wall-mounted boiler`s e.g. gas boiler, base for heating e.g. small commercial installation, has membranes connecting branches to adjunct ends, where one membrane is removed for allowing liquid passage between one adjunct end and branch

摘要

The base has an inlet end (2) for receiving a hot liquid from a heating body of a boiler, where the body receives a cold liquid from an outlet end (5). Another outlet end (3) delivers the hot liquid to a central heating plant that provides cold liquid to another inlet end (4). Ducts (6, 7) are extended from respective inlets to outlets, and membranes (17-20) connect branches (15, 16) to adjunct ends (21-24). One of the membranes is removed for allowing liquid passage between one adjunct end and branch.
