i think that the big buddy just has the fan and 2 propane tanks, also has a higher setting. my partner bought one of the portable buddies after he had a problem with his big buddiy last year and he had a problem with his portable buddiy doing the same thing at altitude, until he got mad and threw it out on the ice, then it has seemed to actually work after that.lucky7 said:Jamie:
Is there a major difference between the portable and the big Buddy?
I've used both buddy heaters and coleman heaters in high elevations, they might not be as efficient but they still work great.Reg said:If this is the one I'm thinking of, somebody told me last year that they don't work in high elevation.
The newer heaters have ODS sensors on them (oxygen depletion sensor) which causes them to shut off, this is a safety feature to prevent carbon monoxide poisoning. I am willing to bet this is what causing your heater to shut off at higher altitudes due to the lack of oxygen already.jamiehughes said:i definetely read the box, but still don't understand why it worked good for one day then not the next. the one i had last year worked the same way..
What happens is the molecular structure of the air at higher altitudes may cause the air-flow in the pilot to increase and blow the pilot flame off the thermocouple, causing the heater to automatically shut-off. Also, if you have a change in weather and the barometric pressure drops, this could also cause the heater to shut down prematurely.
