to heat 50 gallons of wvo in a 55 gallon steel drum- would a 115 volt immersible element heater from a hot water tank do the job? the oil has to be heated to 130 degrees f. I wonder how long that would take with that setup?
2n2222 manages to pooh-pooh every idea that comes on here. Relax, or at least, research.
Here's one that uses a home hot water heater.
The first person did the math, you might want to insulate the 55 gallon drum to speed things up.
Here's a drum heater, pricey but proves 480W will do the job.
