The HERMS coil is about 1-2 inches above the element and not resting on it. The coil with (or without) the fittings installed is very rigid, it does not bend easily. Once you tighten down the fittings it stays in place and feels very firm. The weak link would be the sidewall of whatever you are installing it into. It is pretty heavy so I definately wouldn't try to mount it this way to a cooler or a thinner vessel.

Crap I had forgotton how expensive that stuff was.
It is a 50ft 1/2" OD SS immersion chiller. I ordered it and a 12" false bottom from midwest supplies.
EDIT: Just realized I ignored your second question Gab. I had no intention of putting valves on the outputs of the herms coil. The way I will be using it I do not think it will be necessary. I DO plan to put valves on both sides of my pump. During a brew session I will never remove the clamps from the input or output of the coil. The only thing that I will be switching is the input to the pump. During mash recirculation the input of the pump will be from the output of the mash tun. When I sparge I will switch the input of the pump from the mash tun to the output of the HLT. I'll use the water in the HLT for sparging. I am sure this would be more clear with an illustration but I hope you get the idea.
If you can think of a function for the valves on the coil please let me know, I may have overlooked something.
