We put heaters in the oil pans and hydraulic tanks of heavy equipment on a regular basis, the general rule was no more than 10 watts per square inch of heating element. High wattage units made for water will cook the oil. More info here, https://www.warrenelectriccorp.com/a...rs/default.asp

I siliconed the Moroso heater to the bottom of my aluminum pan worked great, but would leave it on for only about 30-45 minutes.

Thanks for that information Jim. If my math is correct, this heater has 63.69 watts per sq. in. I guess I'll send both of them back. The heating probe is 4" long and .5" in diameter with 400 watts.

I tried a stick on pad but when I saw smoke coming out of the diaper after a few minutes, I took it off.

Some have used a plumbers pad, available at Lowes, to protect their diaper. Pad has to be sealed around the edhes to the pan if it peels it will burn itself up.
