Hi. Do any of you recommend a particular brand and model of CO
detector? I bought one last fall, but now I hear that the kind I bought
is not that good. I was going to buy a few more anyway, and I will
replace the one I have. Any suggestions?
Dont know which country you're in but you want 1 with long term
stability of CO cell; many don't.
The HSE (UK Govn't body} only found 2 satisfactory.
1 was "SF" brand, 1 "Kidde"; latter available both sides of pond.
Hi. Thanks for your reply. I'm in the United States. The brand I bought
is a Kidde, but apparently Kidde makes many different models. The one I
bought is a combined carbon monoxide and smoke detector. Now I hear
that it is not advisable to have the two combined in one device.
Supposedly, the carbon monoxide detectors should be intalled at a much
lower level than the smoke detectors. The smoke detectors should be
installed on a ceiling, whereas the CO detectors should be at about the
level of an electrical outlet or not more than five feet above the
floor. I was told that CO may not rise as high as the ceiling fast
enough to be detected. By the time the CO reaches the ceiling-mounted
detector, a person will have breathed in a substantial amount while
lying in a bed that is much closer to the floor. The one I bought is
only battery operated. I hear that they make CO detectors that can be
plugged into an electrical outlet but they have battery backups in the
event that there is a power failure.
You have very good detectors Co spreads out , your unit will detect it.
I use a Nighthawk Co- Ng leak detector digital display, 120- battery
backup. The nice thing about digital display is the memory high level
function, it allows you to monitor low level peaks that won`t alarm the
system but are a danger sign that something is going wrong. What you
have works. Low levels that don`t alarm will indicate Co from cracked
exchangers, blocked chimneys etc . You can get headaches from low level
even though it won`t alarm.
I have heard this one both ways. While I would think that most sources
of CO will be be heat producing sources and as such the warm air would force
the CO to rise quickly. CO is lighter than air and will tend to rise.
I have had one personal encounter with CO. In that case the CO
concentrations were decently greater at five feet than at four feet and
greater at four feet than one foot. We had a number of people. Many
sleeping on the floor, some sitting upright, some standing. Those standing
where first to be effected and suffered the most during the next few days.
Those sitting also experienced problems, but not as severe. The first
couple who were sitting stood up and were quickly effected. The others
seeing that did not stand up but got to their hands and knees and were less
effected and were able to help the others and alert those sleeping. In the
end there were no lasting injuries.
I have mine mounted about five foot up just outside the bed room area on
the second floor and another mounted at outlet height on the first floor.
BTW the one upstairs is of a new design and can record and display
levels that are too low to set off the alarm, but may be a good early
.. but this is not. The density of air is 1.29 grams/liter; that of CO, 1.25.
This is not a significant difference: the density of nitrogen is *also* 1.25
grams/liter, and air doesn't separate with nitrogen at the top, and oxygen
(1.4 g/l) at the bottom.
Undoubtedly because it was warmer than the air, and hence less dense.
Glad nobody suffered any permanent ill effects.

Hi. Thanks for your help. After looking at a number of different CO
detector models, it appears as if the differences in price amoung them
tend to reflect how sensitive the detectors are at detecting lower
I understand that some posters here think I'm merely responding to
advertising, but this past winter alone, I've heard of several
instances of local residents dying when animals took up residence in
their chimneys, which prevented CO from escaping. I need to put a
wildlife cover on the chimney, but I've been told the chimney needs to
be repaired first. Drilling into it now will probably cause it to
crumble. A few years ago, the co-worker of a friend of mine died from
CO poisoning while flying in his airplane. These things happen. While
they may happen with much lower frequency than other accidents, like
automobile accidents, I would rather be safe than sorry.
look. you are being duped into buying things you dont need. if you keep
researching it you will eventually be convinced you need 30 different types
of CO detectors for your house to cover any and all 'possible' scenareos,
plus one you wear around with you everywhere.
buy any CO detector, or better yet since you already have one, dont buy
anything. install it as per the instructions that came with it, maintain it
as per instructions, and get on with your life.
sure. all the propaganda you need to scare the hell out of you in one
if you bother to read those references you will come to two conclusions:
1) you need one in the garage far more than in your house.
2) some people are just too stupid to stay alive.
look, im not saying you shouldnt have a co detector in your house. i have
one. but in the greater scheme of things, the risk is far overrated. why?
because it sells product. same as burglar alarms, hand sanitizing wipes,
and flu shots.
yeah, maybe one would be. a simple comment. hmm.. how bout a comment
like the one i made... or was it too obtuse for you? you need me to tell
you what obtuse means?
is this my old english teacher or something? you still mad because i dont
believe in punctuation either?
ok ok, im jumping your ass, but i dont need a net nanny. if you have
something to say, say it. if you dont like what i said, or how i said it,
restate it in your own reply. you're pissing in my kool aid.
I agree with Xronger, don't buy stuff you don't need....
It is pretty common here to see people who installed CO
detectors in the all electric houses! Why? stupid TV shows
that scare people into thinking they need CO detectors.
Don't take my word for it... Buy detector, run furnace
set your detector 2 feet away and look at the reading.
If it reads "0" return detector back and save your money
for the furnace inspection every one - two years.
Xronger, Co is not an over rated problem, one instance of several I have
seen was my 80 yr old neighbor kept complaining of headaches, I smelled
nothing and was fine as were other people, I brought my Co detector over
and it read 50 only when the furnace ran, she got out a repairman and
found only because he took the furnace apart 3 -9" splits in the
exchanger. It would have only gotten worse, but even her illness could
have been avoided. Ive had 3 other instances that allowed me to make
equipment replacements or repairs before anything serious happened , Im
no hvac pro just a home owner and have seen the benefits. Ng leak
detectors are not a waste especialy for elderly that do not smell well.
My parents recently did not notice the stove was on and not burning when
I arrived, or sewer gas from a dry trap that stunk up the house so bad I
opened the windows. Yes I got them 2, Co. Ng. detectors. Leaks are
common and houses do blow up. The real point is for 50$ you have
insurance, ten-20 years ago it would have cost thousands.

Hi mRansley. Can you tell me more about the sewer gas problem? A few
weeks ago, I noticed a foul, sulfur-like odor coming from the
downstairs bathroom, which I rarely use. I couldn't pinpoint exactly
where in the bathroom the odor was coming from. I just knew it was from
the bathroom. I flushed the toilet several times because I thought the
water might have been stagnant because, as I said, I rarely use that
bathroom. I have not noticed the odor since that time. Could that have
been a sewer gas problem? I tend to doubt it because I tend to think
that if it were sewer gas, the problem would have persisted in spite of
my flushing the toilet. Would the sewer gas smell like rotten eggs?
Is there a bathtub? Every few weeks you need to let some water into the
drain to keep the trap filled. Same with the sink. Traps under sinks and
tubs stop gasses from the sewer only if there is water in them.
