Propane v. Natural Gas

I just moved to a home where there is natural gas being piped into the garage for a garage heater. I was thinking of re-tooling my burners with jet/orifices that can handle the lower pressure of the natural gas v. the propane tank hook ups I use now.

Does natural gas have more or less BTUs than the propane? Would you expect a longer or shorter "time to boil" if I switch over?

If I'm reading these figures correctly, Natural Gas contains 23,000 BTUs/Lb. vs Propane's 21,000 BTUs/Lb. How the propane council baka references comes up with their numbers likely has more to do with marketing spin (measuring energy density by volume, not mass) than science, I suspect. How effectively you can utilize that and what it's going to cost you is another thing entirely, but as far as I can tell, Natural Gas is more energy dense by weight than Propane.

It looks like propane is more than twice as energy dense as natural gas.

I do not know if that means a 100kBTU burner would be a less-than 50kBTU burner when using the different fuel, though.
