Heaters are improving and the Penn-Plax is among the worst design-wise. Just knowing Ebo-Jager, I would expect better and I can see from the outside some good points. The design of the top of your heater looks good. If you spill water on your heater it is likely to run off the edges. The brown cover on the Pen-Plax is a cup where the adjustment sets. Any water spilled on it will set in the cup and eventually find it's way along the screw and inside. I know we are not supposed to get water on them but that is like telling a five year old not to get wet when it rains. Just happens!
