i read in an earlier answer that radiators shouldnt really be bled often, is that right??? would the pressure would be low in a sealed system if there is air in the system instead of water??
The point is that rads shouldn't need to be bled often.
The cause of gas in rads can be one (or both) of three things:
1. Air being drawn down the vent (on an open-vented system);
2. Air bring drawn in at a poorly sealed joint;
3. Hydrogen being generated by electrolytical corrosion.
Pressurised systems tend not to be subject to the second type, but the generation of Hydrogen will result in loss of pressure, because it will compress more than water.
