It's my choice to be sure, but be sure and read the manual
. Installing it in a small egg camper
with the required clearances can be a challenge. If wall mounted and left uncovered then the life of the catalytic element may be shortened by contaminates (dirt). It requires fresh air and can produce unwanted combustion by-products if there is not sufficient oxygen
(but there is a O2 depletion shutoff also). And some people do not like that type of heat and prefer something more like the forced hot air they have at home.
On the plus side, its super efficient and requires no electrical
power (not even batteries).
