Heating valves
The BA-Filling-Combi 6628 automatically fills and refills central heating installations. It is permanently connected to the potable water pipe as stipulated by EN 1717. When the supply pressure falls below the pressure of the heating installation during the filling operation, the integral BA backflow preventer prevents the backflow of heating water into the potable water pipe. Even heating water with inhibitors (anti-corrosion products and antifreezer) can be permanently connected to the potable water system by means of the BA-Filling- Combi, which makes the laborious hose connection unnecessary. When the system is filled, the isolating valve of the BA-Filling-Combi should be closed again.
