Use Blichmann's Low Level Float Switch along with your electric Tower of Power control modules to automatically cut the power to your Blichmann BoilCoil heater. It mounts to the sidewall of your pot to keep the element dry and avoid any scorching, and will shut off automatically if the water level dips below the required amount. Choose the 'Blichmann Hole Punch for Float Switch' upgrade option to have Blichmann punch the hole in your BoilerMaker kettle to allow for installation of the float switch.
