Default defying science (boiling point)

I have installed an very big heating element into a plastic fermenter.

Just did a test run - water reached 4 degrees above boiling point (at all points in the water) and I got gentle boil. It was violent over the element...but everywhere else was more of a relaxed boil.

Any ideas how I can fix this? Do i need another element?

Thanks

boiling point of water will vary depending on the amount of dissolved minerals/salts (more salts will elevate the BP) and of course your elevation.

Are you saying you want a more vigorous boil throughout? If so maybe another element would help.

i was led to believe that vigour was of importance when I advance from basic brewing?

Dissolved sugars will raise the boiling point of the solution, one half degree celsius for every 180 grams of sugar. Not sure what you want to do with that tidbit--I just found your question interesting and it sent me searching online!
It's not your altitude, unless you're brewing on a submarine.

I would suspect the thermomenter.

Cheap thermometers are notoriously inaccurate.
