I use two 120v heatsticks to heat water and boil the wort in the basement.
I found that one is not enough and two gives a too vigorous boil. And so, I devised a regulator that controls one of them.
Every few years, I have had to replace one of them but they are easy to construct.
Also after brewing, as I am cooling the wort, I clean the stick to avoid any wort buildup on the elements.
Another advantage I found is that I can start heating the wort as I continue to sparge.
The only disadvantage I found was when I went from using a 5 gallon pot to a 10 gallon.
