A catalytic heater would burn natural gas, LP, or propane just like a
furnace or stove burns it to generate heat. However, there is would be no
flame with a catalytic heater. Therefore the same applies as with
burning: gas + O2 -- CO2 + H2O.

I agree, Han.. but I'd think that the difference with a portable
heater is that the furnace or stove would most likely be venter to the
outside..
