VEVOR Metal Drum Heater, 800 Watt 7.75 inch Width, Pail Heating Band for 5 Gallon Barrel, 86-302℉ Adjustable Thermostat, High Efficiency Silicone Grease Keg Heater, FCC Listed Orange

This will work on an empty plastic bucket.

It will work on honey. The temperature should not be too high, it is recommended to be within 55 degrees

According to the product description, it has an adjustable thermostat with a range of 86℉-302℉. Customers consistently report that it heats well and maintains its temperature, but note that care must be taken when using it on plastic containers.

The product description states it is made of high-strength silicone rubber materials to ensure durability and long-lasting performance. Customers agree with many noting its durability. One review mentions it melted a plastic bucket when left on maximum heat, but this appears to be an isolated incident of improper use.

I did not find any reviews explicitly discussing the use of this product with flammable liquids. For safety regarding heating flammable materials, it would be best to consult the manufacturer or a qualified expert.
