Water flows into the top of the rad and is sucked in the lower hose. Another import trick on stats is to drill a small (1/16) hole in the flange allowing any trapped air behind the stat to escape and not create a air bubble. This allows the stat to open easier without a temp surge to get it done. Reduces thermal shocks to the system as well.
