PA24, I installed heating elements in my tank and it certainly boils water. Only complaint is it only boils about 8" worth on each end. You don't have this issue? I'm probably going to swap the elements for longer ones.
gunmaker,
You can put longer elements in your tank or just add two small additional elements low on each side. Do a little homework on what elements are available, there are quite a few out there. When it is boiling,
all the water is boiling, just not all bubbling at once, this has no negative effect on how nice the barrels blue/black. The longer it runs the more aggressive the boiling bubbles will become.
In fact my tanks bubble too aggressively and I shut down one element to slow the bubbling and alternate off/on from end to end during my rusting cycles to maintain an even water temperature.
Hope this helps.
Best Regards,
