Thanks every of your thoughts and opinions. I am interested in using kerosene as that is what we use to heat our house here in Minnesota. We keep it a nice 75-80F, even when it is -20F outside. :-). It is reasonably cheap compared to NG in our old house.

If you use K1 grade kerosene and keep the space heaters adjusted right and dry burned when needed, no stinky fumes. A little smell at start up and shut down.
