I am building my rig for all grain and have been thinking of adding some electric water heater elements to my boil pot and hlt, i would like to use a pid controller as a thermostat but would not mind an on/off switch depending on the cost and difficulty. i am mainly looking to cut down on bringing to boil times so on/off is is ok in my book i can add a controller later. can you add an element to a gas fired keggle? i plan on two 5500w elements per pot + the existing 170,000 btu burners. the elements will be parallel to each other about 6 in apart coupled in from the back of the keggle i have commercial three phase power to my house and shop so i can run all at once if i need to, though i dont think i will need to. I want to leave the gas burners in place mainly for portability reasons, it seems electric is more efficient and cheaper to run and if i have to turn the gas on to speed things up I have that option. i dont have much experience with the electric stuff so i thought id ask you guys before i start experimenting.
