COMFORT Filling Combi BA A24 DN 15 Heating Water Treatment Connection No. 6628.20.886

The FüllCombi BA A24 is designed for the automatic filling and refilling of central hot water heating systems in accordance with DIN EN 12828. It is permanently connected to the drinking water line as per DIN EN 1717. If the supply pressure drops below the heating system pressure during the filling process, the BA backflow preventer (approved for fluid category 4 and below) integrated into the FüllCombi prevents the backflow of heating water into the drinking water line. Even heating water with inhibitors (corrosion and antifreeze agents) can be permanently connected to the drinking water installation using the FüllCombi BA, eliminating the need for the previously common hose connection. For safety reasons, the FüllCombi BA's shut-off valve should be closed again after the filling process is complete. Direct connection option for heating water treatment via a double-hose system, meaning only one hose needs to be installed. The FüllCombi BA A24 consists of an inlet shut-off valve, an outlet maintenance shut-off valve for operation with an Allen key, a pressure reducer, a double pressure gauge, a BA backflow preventer, and a waste water connection. It thus contains all components for the standard-compliant filling of a heating system.
