<p>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.</p> |
