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!

You leaveit on, you just don't bleed the air out of 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.

Power flushing does NOT increase the pressure, only the flow
