Heat is expressed in BTU's a quantitative measure of heat.
If an oil pan in still air of 0 deg. F. loses 5,000 BTU's / hr., and the same oil pan, in the same 0 deg. F. air loses 10,000 BTU's / hr. because of it being exposed to wind, then yes, the one in the wind is losing twice as much heat as the one in the calm air is.
In fact you could say the heat is LOOSE because the wind is blowing it away. ;-)
BTW, oil heaters, be they adhesive, magnetic or immersion are widely available and reasonably inexpensive. Why run 0 deg. F. oil through a 140 or 150 F. deg. engine and cool it back down, the goal is heat, not cooling.
