I am glad that I bought this Heizkörperentlüfter. It works flawlessly. Since, also most likely collects the air in the radiators that are located at the highest point in the house, I did it first with this air vent. I then observed, in which radiators then still collect air and then converted them. It has to be refurbished each radiator in a family house in my opinion not necessary. The set of 5 is in my house have been sufficient to eliminate the problem. The installation takes about 10 minutes per radiator. Heizungsthermostat completely turn the radiators - turn return of the radiator - radiator completely vent until no more water comes (the water may be hot!) - Unscrew the old breather - screw the automatic air vent - the thermostat and return open - finished. The prerequisite for this simple assembly that the radiator of the pros and return can be shut off! Tools needed: A cup for the water - a rag - a 19er wrench for the automatic air vent - a wrench for the old breather (22er with me) - an Allen key for the return valve (with me 6 mm) - a water pump pliers to the cover of the To remove the return valve
I highly recommend this product. No cluck in the heating and the more annoying vent now also falls away.
