Default Help sourcing BK element power controller

I have a 10 gal BK with 220v 4500 watt heat element. Simple manual system no PIDS , pumps or HERMS. i need to source a device (rheostat?) with which i can dial down the amount of current to heater element to maintain a good rolling boil.
Looking for cost effective solution. My only thought is some sort of electric range element controller. Any help would greatly appreciated

Google "PWM". You'll need to get a 25 amp SSR (solid state relay) as well and a power source for the PWM. Usually an old cell phone charger will work.

Hack the cell phone charger to power the PWM. The PWM connects to the control side of the SSR. One leg of the 220v goes through the SSR then on to the element.

Since PWM's typically don't go 100% on or 100% off, unless you get one with a potentiometer with a power switch built in, you'll want to put in a switch for the element to ensure you don't dry fire it.
