EDIT - After many different attempts, I've learned these bucket heaters definitely shut them self off when the water starts boiling (and turn back on when the water drops somewhat below boiling), unfortunately. IMO they are only useful for HERMS.
I purchased 3 of these bucket heaters to assist my induction stove boil wort.
The instructions state the following safety warnings:
- DO NOT COMPLETELY IMMERSE THIS PRODUCT IN WATER. The handle and power cord are not designed to withstand boiling water. Always keep the handle and power cord out of water.
With 2 of them, after 1 hour and 30 minutes, 6.5 gallons of water approached boiling but never got there. Once I attached a lid to the kettle, it began boiling (albeit not that much).
Here is how I attached a lid to it:
What I'm concerned about is that there is condensation forming on the handle/guard, with or without the lid. The lid simply concentrates the steam to the handle/guard.
Is this safe? I hope to just keep the lid on until it boils and then take it off. I've ordered a third to see if it will boil stronger.
