I am using camco 5500w elements and keggles for my HLT and boil kettle. I was doing a test run of my system with just water since I recently finished putting it all together. I noticed when the water is heating up there are tons of little bubbles all over the elements. As the water gets hotter, these bubbles get bigger. I assume this isn't good for the element as those bubbles are obviously air pockets and would not allow the element to transfer heat effectively thus heating up more than it should.
Are my elements working as intended or should I try some new elements?
