Hi,

I've just fitted a couple of cast iron radiators, picture of which can be
seen here - http://img292.imageshack.us/img292/8771/dsc00222ax9.jpg.

They warm up OK but only the bottom half of the radiators. I'm guessing
there's air at the top which is causing the problem. However, the only
valve fitted is a few inches above the outlet (you can see it sticking out
on the picture). There's no valve at the top of the radiator.

Is this normal? Is hot air gathering at the top causing them not to heat
up? If I open the valve, then water just comes out.


IANAP......But.....Perhaps you lay the rad on its side and fill with the
bleed hole open to expel air then mount upright
