Good to see you admit to an honest mistake as many youtubers only talk about there triumphs and never admit to their errors. Many thanks for your very helpful video.
We actually have one, that's the "gas sniffer" I talked about near the end. They should be required on boats, really, but they're optional for some reason.
Turns out there are multiple types: smoke detectors, with or without heat sensors, heat sensors, Carbon Monoxide (CO) detectors, and LPG Gas Sniffers. And basically it's smoke detectors and heat sensors HIGH (generally the highest unobstructed point on the ceiling, or high on the walls. CO alarms at head height in most areas, bed height where you sleep. Gas sniffers low as can go, because LPG gas is the one that is much heavier than air and will pool down and displace breathable air. For that reason the sensor should actually be in the bilge of the boat, if at all possible. On a boat the only one that's really at all optional is the heat sensors, due to the small spaces and odds that smoke would build up first. And, except for the gas sniffer, they're all among the cheapest things you can add to the boat! M.
I did too until I really thought about it! It's those damned memories of dry ice experiments in chemistry class, coupled with an inconvenient propensity to forget about that extra oxygen! M.
CO is the same density as air so it doesn't naturally rise. However, as it's a product of combustion, it is usually warm and will, therefore, rise. All the points you make are correct although you shouldn't place it near an air vent for the same reason as a window. People should also be aware that the source of CO may we'll be outside the boat so a CO alarm in each "room" is highly desirable even if you have no appliances within the boat.
Wouldn't you want it "close to head height", but at the height your head is at *when sleeping*? [edit]: I should watch further before commenting :) You cover it for the bedroom
Invest in some hex head drill bits then. www.amazon.co.uk/Am-Tech-4-inch-Titanium-Coated-Drill/dp/B0031NCINK/ref=sr_1_1?rps=1&ie=UTF8&qid=1499445291&sr=8-1&keywords=hex+drill Besides having WAY better holding power in the chuck, it also has the advantage of not having to spin the chuck so much when going between two sizes (because the hex's are all the same size). Trust me. Get them. non metric: www.amazon.co.uk/Paor-Titanium-0-5-6-5mm-Builders-electricians/dp/B01K7MY0L0/ref=sr_1_20?ie=UTF8&qid=1499445620&sr=8-20&keywords=hex+drill
yeah just to mention that the test button only tests the batteries, not the actual CO sensor. these units have a lifespan of 6-7 years (check manufacturers advice) will need replacing as they get older.
Thank you for this video on CO detectors. I have has my head bitten off and deleted so many comments I have made due to abuse on this. In future I will point disbelievers here. :-)
Tell them to call the manufacturers; the instructions are very much aimed at residential home installations, and for boats and RVs there's -- obviously -- a lot of confusion, which is how we got it wrong, though I tried to read them precisely. The reality is it's people living in vehicles, and around other vehicles, where the risk is greatest, but there's no clear guidance for that particular situation. Glad this helps a little. M.
Love ya vids! Great to see some sensible advice for safety in the boat thank you, I also had same dilemma when replacing my detector! Keep on keeping on guys! And get ya self a makita drill driver and impact driver set lol 👍🏽👍🏽👍🏽😂
Oh no, they're all in front of me, I'm sure. We do have some idea where the wiring is -- I've disassembled the socket below to check -- albeit just some. M.
The thanks really goes to the technician at FireAngel (www.fireangel.co.uk) who was patient enough to explain it all to me on the phone! But you're welcome! M.
CO2 is not the problem, it is CO. I have expienced c02 when workng in a commercial greenhouse [a faint], and CO when [foolishly] using a marine gas stove as a heater on a cold night, better to shiver than to die!
Well, that's got a bit of a long answer: Oklahoma, by way of California, Saudi Arabia, Vancouver, Toronto, California again, a trip around the world, New Zealand, California one last time, and now the narrowboat Perserverance! M.
CO is lighter than air so it "pools" on the ceiling and follows the air flow in the house or boat, so in fact both your detectors were in the right place originally. the main point is fitted detectors work, which most don't.......atb
We tried to make that clear; CO is not lighter than air, it's the same molecular weight as N2, the largest component by a huge degree of air. At the same temperature as room air it's naturally going to move with convection currents and that's it. It will usually be hotter than your room air, because it's coming from a fire, but that's not necessarily true, especially if the CO is coming from your neighbor's badly maintained engine and you've a nice clean fire going in yours. But, yeah, the key point is ALWAYS have a long-life CO detector fitted, placed correctly, and tested occasionally. M.
Amazing the number of 'authoritative' videos here that say carbon monoxide pools towards the floor! Appreciate the info.
Indeed!
Good to see you admit to an honest mistake as many youtubers only talk about there triumphs and never admit to their errors. Many thanks for your very helpful video.
I feel like all I'm doing is showing people my errors! Thanks for watching! M.
Main point is you learn from mistakes, and we all make them, as we are only Human 👍😎✌️
I've been trying for human for 40+ years ... so far the costume is working! ;-) M.
An extremely useful video which is very helpful to all. Many thanks for explaining so well and sharing.

Hey guys enjoy the channel. Look into a lpg detector. There normal on US RV's.
We actually have one, that's the "gas sniffer" I talked about near the end. They should be required on boats, really, but they're optional for some reason.
Hi that has helped
Really useful info, thank you for checking and finding correct guidelines!
Always trying to get it right! Not always succeeding! M.
Oops, I thought they went near the floor. thanks for the info. and I didn't know there are two types either. thanks again. very helpful.
Turns out there are multiple types: smoke detectors, with or without heat sensors, heat sensors, Carbon Monoxide (CO) detectors, and LPG Gas Sniffers. And basically it's smoke detectors and heat sensors HIGH (generally the highest unobstructed point on the ceiling, or high on the walls.

Sorry old bean. I thought monoxide pooled as well. Boy is my face red.
I did too until I really thought about it! It's those damned memories of dry ice experiments in chemistry class, coupled with an inconvenient propensity to forget about that extra oxygen! M.
Ditto!
Good info. On a side note you have a great voice and keep expecting you to start singing "I'm only human". Bet you could as well :)
Jo has heard me singing. This is not a singing voice. ;-) M.

Very true on all counts, thank you!
Wouldn't you want it "close to head height", but at the height your head is at *when sleeping*?
[edit]: I should watch further before commenting :) You cover it for the bedroom
Patience never was your thing. ;-)
Nah.. ps. Speaking of patience... let the drill make its way back out, don't pull (and/or TIGHTEN the cheap chuck!)
It's a very cheap screwless chuck, that's as tight as it goes!

Turns out RUclips flagged this as "likely spam" ... plus their silly app won't let me follow links anyway!
yeah just to mention that the test button only tests the batteries, not the actual CO sensor. these units have a lifespan of 6-7 years (check manufacturers advice) will need replacing as they get older.
Yep, ours is a 10-year battery model... should be another 6 years before it needs replacing! M

When budget allows! M.
I half expected when you drilled into the side wall you would hit some wiring, but perhaps those mishaps are behind you now. lol
Oh no, they're all in front of me, I'm sure. We do have some idea where the wiring is -- I've disassembled the socket below to check -- albeit just some. M.
So happy you have it all sorted out now. :)
Yes! Thank you so much for commenting. It made us think twice! :)
Thanks for that good explanation of the right positions of the alarms, as on many boats they're fitted wrongly against the ceiling.
The thanks really goes to the technician at FireAngel (www.fireangel.co.uk) who was patient enough to explain it all to me on the phone! But you're welcome! M.
That's so good to share as I'd probably have made the same mistake. Thanks.
Glad it helps! Thanks for watching! M.
Very helpful, thanks. Ps I love your outtakes!
+Dulcie Barnes thank you!
One of the best boat vids on youtube because this one may well save a life. I hope the other boat tubers give it a shoutout.
Thank you! And I believe they already are! M.
Excellent advice. This is so frequently misunderstood. We have two CO2 detectors in our Airstream, just in case.
Realizing how often boats near us are running their engines in the night, I can't imagine not having them anymore. M.
CO2 is not the problem, it is CO.
I have expienced c02 when workng in a commercial greenhouse [a faint], and CO when [foolishly] using a marine gas stove as a heater on a cold night, better to shiver than to die!
Very good advice about the danger of CO.
Thanks! M
Need to move ours as well keep the videos coming !
Thanks and will do! M.
Nicely explained. Thank you.
You're welcome!
Good information. Thanks for sharing
Now, here's hoping they work!
great a life saver . thanks for making
+clive kibbler Glad you liked it! M
Michael, where are you from?
Well, that's got a bit of a long answer: Oklahoma, by way of California, Saudi Arabia, Vancouver, Toronto, California again, a trip around the world, New Zealand, California one last time, and now the narrowboat Perserverance! M.
cool shirt!
Thanks! My friend designed that one! www.littlebluestudios.com/
