How efficient is a typical "LPG heater"?

I presume they must vent the exhaust outdoors, so what's a reasonable
number for the percentage of BTUs in the gas that actually heats the
workspace?

Does it vary significantly with the design (and era of manufacture) of
the LPG heater?

I expect that electric heat must be near 100% efficient, huh?

My inquiring mind wants to know...
