From what I have been reading up on, the hot stove (yeah, punny huh

) is one called the Partner Stove.

They are expensive, but many use these that go on expeditions and white water rafting guides.
Myself, I like the Colemans, white gas or propane, but as stated earlier, proopane is my preference.
