I'm trying to convert my crude oil into heated crude oil, but there's no way to do so. I'm playing on HBM-NTM-[1.0.21_X5027].jar, MINECRAFT 1.7.10, the NEI mod shows no recipe for "OIL HEATER" and the "BOILER" mod doesn't allow any fluid other than water.
Any solution?

Oil heaters are disabled and their recipes were removed, use industrial boiler or regular one

The large copper boiler can have its input type set via fluid ID, the old oil heaters are deprecated and only spawn as decorative elements in some structures in the most recent versions.
