The Flamco XStream Vent ensures that air in the installation is separated quickly and efficiently. The result: more comfort, less corrosion, less noise and more efficiency of the heating system. The Xstream Vent has a unique ECO/ MAX mode. In the ECO mode a part of the system water (partial flow) is led through the Flamco XStream. In the MAX mode all the system water is led through the Flamco XStream. Up to 15% less energy consumption of the heating system.* Up to 6% more efficiency of the heating system.* The unit is 360 degree rotatable for ease of installation. No account needs to be taken of the flow direction of the installation. This prevents installation errors. Insulation is an integral part of the design of the Flamco XStream. This reduces heat losses to a minimum. The intergrated service indicator indicates when the system was last flushed/vented in the MAX mode. * Calculated according to the Hysopt method in a system with a gas boiler and manually operated radiator valves
