The highest radiator in my house (bathroom towel rail) keeps half filling with air. Any ideas why? - bathroom rails
It can be caused by an accumulation of mud on the bottom of the cooler, which inhibit the flow of water. It's a liquid withdrawal of sludge disposal. Add the liquid feed and expansion tank. Two days later, it will be necessary to drain and fill the system.
If the pipes are more serious, may result due to lack of water in the system, a leak or a design flaw somewhere in the pipeline. If the bleeding does not help radiators, the problem is more serious. Locate the pump and find the flow. Observe the body before a screwdriver to turn it very quickly seen for a couple of times. If this does not work, try to bleed the pump. The drain valve must be pumped in the upper body visible. Open and close very quickly with a screwdriver. When you hear the hiss of the air - were found at fault.

Bathroom Rails The Highest Radiator In My House (bathroom Towel Rail) Keeps Half Filling With Air. Any Ideas Why?

This system is in English? I have never seen how these systems with tanks in the attic, where I am here in the U.S..
But I saw an interesting case, "This Old House" I believe that in a closed system hot water with a similar problem, the highest in the cooler, two floors above the boiler in the basement where the collection of the air.
It was resolved by the pump on one side of the boiler to another. I was not very good logic, but I think the theory is that the bomb in front of the boiler to create a Vacumn was down and drag the water in the boiler. This draft Vacumn generated by the creation of a vacuum. The air, of course, reflected on the ridge.
By moving the pump was on the other side of the bomb "surge" of water, which Vacumn and solve the problem of air.
It was a rather technical theory, it can not be sure that for the same reason.
But good luck to him.
This is very common if your system is old, is caused by corrosion products of iron in the system and a chemical reaction between different metals to create hydrogen (but always as "air" to produce) known and seems to occur when a new boiler an old system provided. Sometimes a color that you will help (if you get water when soiled rad bleed, recommended a power flush, that the mud is present, and this leads to a gradual deterioration in the efficiency and) premature wear of system components. If the water is clean, if the bleeding rads, it is likely that Powerflush not necessary, although it is a good idea, an inhibitor feed and expansion tank placed in the attic
Does not bleed air for the boiler. Turn the boiler wait, 10 minutes, because rising air, then they will bleed. It is filled with air, because it is the highest in the radiator and the air will rise to the highest point. But check it must also rads for other air.
Your heater has fired through a valve air. Does near the top. There must be a method of bleeding air from the system.
