Purchased this to replace the old barrel design plastic air vent on my central heating system that was leaking. It took considerably more effort to bleed and refill the system (and getting rid of the subsequent air locks), than to fit this. A couple of layers of white plumbers tape, and it fitted perfectly without any leaks. It is clearly better built than the plastic valve as well, and operates much better. Although it doesn't come with any instructions, if you download the Flamco manual it recommends that you loosen the cap before filling the system and tighten afterwards. The location of the valve is critical as well, it should be on the highest point of the system after the water pump to prevent air being drawn into the system. While not a "Silver bullet" for a central heating system with an airlock issue, the Flamco was not designed to be that. There are many reasons for airlocks occurring in a domestic CH scenario, and an airvent valve may or may not be the solution. If you purchase it as a replacement part with this in mind, you won't go wrong.

Instalé estos purgadores automáticos en la instalación de mi caldera de gasoil hace ya varios meses y la experiencia está siendo muy positiva. Desde el primer momento se veía que constructivamente eran de buena calidad, bien acabados y robustos. Con el paso del tiempo lo he podido confirmar: después de varios meses funcionando, siguen trabajando perfectamente, sin fallos ni pérdidas. Cumplen su función sin tener que preocuparse de nada. Producto fiable y recomendable.

Ich habe mir den Flamco Flexvent Schwimmerentlüfter R3/8 27750 gekauft, um meine Heizungsanlage von Luft zu befreien. Der Entlüfter lässt sich sehr einfach montieren und funktioniert einwandfrei. Der Entlüfter ist aus hochwertigen Materialien gefertigt und ist sehr robust. Er ist mit einem Schwimmerventil ausgestattet, das die Luft automatisch ablässt, wenn sich zu viel Luft im System angesammelt hat. Ich bin mit dem Flamco Flexvent sehr zufrieden und kann ihn uneingeschränkt weiterempfehlen. Positive Aspekte: Einfache Montage Funktioniert einwandfrei Hochwertige Materialien Robust Automatische Entlüftung Verbesserungsvorschläge: Keine Fazit: Der Flamco Flexvent Schwimmerentlüfter R3/8 27750 ist ein zuverlässiges und effektives Produkt, das sich für jede Heizungsanlage eignet.
