How does it work?

Keep the rad turned off? If you turn it on won't it just refill?

What am I missing?
It's going to be full of air... As the heating heats up, it compresses the air in the radiator and that takes the expanded water. It only lasts a week or so though.
 
So you keep the rad turned off? I'm still a bit lost on this one. How can it be used if it's full off? I understand it's full of air but the air is in the rad with both valves off so it can't go anywhere

Sorry if I'm still missing it!
 

I use these Bristan Bar Valve Wall Mount 10 Fixing Kit Chrome-Plated | Spares and Parts | NoLinkingToThis the fitting is actually this side of the tile – no need to worry about any leaks, cos it’s all soldered behind the tile.
