Propane vs kerosene warmness? I was thinking of getting a forced nouns heater for working contained...

I was thinking of getting a forced nouns heater for working contained by the garage. Between propane and kerosene heaters I was wondering if anyone would know which one would be cheaper to use fuel learned and which would be safer carbon monoxide wise. I know they both endow with off CO and it wants to be vented but I thought I hear somewhere that kerosene burns cleaner. I appreciate any input.
Answers:    I would say that both burn pretty verbs. The problem with propane is the gas is solid and if there is a trickle the gas flows along the floor and ignites. Kerosene have a slight odor to it. I think in attendance are kerosene heaters as big as VW's. Both produce very ample amounts of CO so be careful contained by a closed garage. If you can pick up a CO alarm and put it in a place within the garage to let you know its getting dodgy. I have used both and the propane seem to give me a splitting chief ache
better even so get a elect radiator if you have 220v contained by the garage, or even 110v, get a grease filled kiln for it,
