Large oil/steam jacketed boiler questions

[Malthead247]

Hello! I am looking to upgrade my equipment and would love the ability to distill on the grain.
I am looking at importing something like this:

The thing I am not certain about is the ability to run these as oil jacketed boilers. They are 'steam jacketed', but does this just mean that it is an double walled vessel that is heated with immersion elements? So it would be possible to run oil?

Any advice, thoughts, and suggestions around this specific equipment is hugely appreciated!
