Hops Additions Method

In my old system, I made a hop sock from a 4"-3" PVC Adapter, a hose clamp, a hops bag and an 18" piece of 1/2" copper tube resting across the rim of the keggle... I would put a weight in it to keep it open so I could add hops...

I just set all that up and am waiting for the wort to boil down to the right level before I start my hops additions (because I misremembered how fast the wort boils off)...

Then it hit me that the whole reason I did this was to keep the hops bag from getting scorched or a hole in it by getting too close to the bottom of the keggle where the flame was...

But since I have now switched to an electric element with a false bottom (>1/2" clearance between element and false bottom), I'm wondering if this is even necessary now...

Would I run into trouble if I just put the hops in a hops bag, tied the top in a knot and threw it in the keggle without a weight or anything? I'd need three hops bags instead of one, but it sure would be easy...

I don't have any first hand experience with what you propose but I would be concerned with the bag of hops resting on the element thus preventing wort from contacting and extracting heat from the element. If that occurred a hot spot would develop and burn through the bag. You could always do a test with water and a bag filled with something that simulates hops so you can visualize. Perhaps if the boil is aggressive the hop bag will move around enough so this won't be an issue?
