Thinking of buying this unit too. Has auto oxygen shutoff in contrast to
the Coleman versions. Anybody have experience with this gadget, good or
bad?

Greg,
I have the Mr. Heater Little Buddy on my boat. It works great.
Haven't had a problem with Carbon Monoxide. I've got Carbon Monoxide
detects onboard and they've never chirped once while running the heater
all day and night. I run mine off a 20 lb tank. Running it on high
when I get home from work until the next morning (about 14hrs) I get
about 4 days run time out of the tank. The manufacturer states that it
will give 50hrs run time on high and 100 hrs on low off a 20lb tank,
and I have found those figures to be pretty accurate.
I can tell you this, that one Mr Heater Little Buddy heats my boat
much better than my three built-in electric heaters on the boat. It
also helps take the dampness out of the air, which the electic heat
didn't touch.

The by product of burning propane is water. Your little buddy is
putting lots of water into the air.

Bought one to compliment the red dot heat my 25 footer has on it (dealer
didn't know it). Anyway, on a 38 degree night, my wife and I got it toasty,
turned it off and crawled into the cave (aft cabin). Was just fine all
night. Given that, I see no reason to leave it on all night. It does have
the oxygen shutoff but why chance it?

-Greg

You know, I thought about that when I first noticed last year that it
felt drier with the propane heat. Combustion creates water, but it
actually feels like a 'drier' heat. Its probably just because the
Little Buddy heats so much better that the relative humidity is less
even though there is physically more water in the air.

Is now a good time to point out that this detector does NOT detect the
presence of POISONOUS Carbon DIOXIDE this heater pours out as it consumes
all the OXYGEN required for life?

It's BURNING fuel, using oxygen from the air and pouring its crap into the
exhaust THAT EVERYONE IS BREATHING. Well, Duhh.....

Humans are too stupid to use UNVENTED heaters. They should be outlawed.
The LEAST they could do is put a button on the side of them you had to
press every 10 minutes or they would shut themselves off so stupid humans
couldn't SLEEP with the damned thing killing the innocent children.

You're mixing up two concepts here. CO2 is NOT poisonous. CO, on the other
hand is. However the absence of oxygen that may result from the creation of
CO2 can result in death if the O2 isn't replaced, just as the absence of
oxygen for any other reason can do the same.

Actually an excess of CO2 can be a problem, it's just a problem at a
higher concentration than CO is. The IDLH (immediately dangerous to
life and health) limit for CO2 is 40,000 ppm whereas CO has an IDLH
of 1200 ppm

CO2 is regarded as a simple asphixiant, just like an excess of
nitrogen or any other inert gas.

Matter of fact, O2 at high pressure and concentration is poisonous, leading
to convulsions and ultimately death..

Most of the time what happens with O2 in excess of 23.5% is that there
is so much danger of fire (asphalt becomes combustible in pure
oxygen).

I don't know what I'm talking about!

Given that:

I'm of the impression that Rosalie is wrong, ie. CO2 is not "poisonous".
I also think that Dave is wrong.
I don't think that I would survive on a mixture of 80% CO2 and 20% O2. The
process of living is not unlike combustion in that the body converts "food"
using O2 to produce energy with a byproduct of CO2. The body needs to
eliminate that byproduct through the lungs. If the partial pressure of CO2
is high, then the transfer of CO2 "out" can't happen (efficiently) and
consequently the transfer of O2 "in" won't happen (enough). I have no idea
what the ratios of partial pressure are that would result in problems are
but suspect that they are finite.

Please refer to the first sentence.

You're exhibiting the same confusion. The difference between CO2 and CO is
that CO2 may displace oxygen in the air, reducing the oxygen concentration
below the level required to sustain life. It is, as you say, an
asphixiant,
but is not a poison. I suspect that the assumption behind the figures you
quote is that the remaining gas other than the CO2 is air. Unless I'm
mistaken, you could live for an indefinite period breathing a mixture of
80%
CO2 and 20% O2, just as you could live for an indefinite period breathing
80% helium and 20% O2. CO2, being inert, doesn't combine with anything in
your blood's hemoglobin to block oxygen transport.

CO on the other hand, is a true poison in that even if there is enough
oxygen in the air to sustain life, the CO would prevent the blood from
transporting the oxygen from the lungs to the brain and other organs.

Matter of fact, O2 at high pressure and concentration is poisonous,
leading
to convulsions and ultimately death..

Most of the time what happens with O2 in excess of 23.5% is that there
is so much danger of fire (asphalt becomes combustible in pure
oxygen).

The context I'm familiar with is diving, where part of the decompression
process when you've been breathing helium oxygen mixture involves
switching
to pure O2 at the 60 ft. stop to reduce the partial pressure of the helium
and flush it out of your system. Can't switch at lower depths because of
the
risk of O2 poisoning at higher pressures.

I don't think this is quite right.
An excess of nitrogen displacing oxygen leads to loss of consciousness
- often without prior warning, while the cognitive response
deterioration is not detected.
An excess of CO2 however, leads to respiratory distress, possibly
panting i.e. we have a physiological , maybe evolved response to the
stuff.

? Have you tried a paper bag over the head
for CO2 enrichment?
