Q on carbon monoxide detector & tank heater

In addition to replace them per the manufacturer suggestion, we all should test it regularly. Not that I practice what I preach...

I don't know of any battery powered propane detectors.

I'd recommend the Xintex (I said Xantrex in a previous post, duh, brain fart) cause I'm used to it on boats. It has a sniffer that you can put in the best place, plus a readout gauge that you can put in a different place (no stooping down to see it). I don't believe they expire, but you do need to keep greasy sprays and the like off the sniffer (not necessarily hard, I just mention it). Since I don't have an electric solenoid on my propane, I'd use this one:

(Later models of Chinook may have an electric solenoid; there is a different model for that).

Not as cheap as the RV ones, which I think are around $60?

For CO, this is what I bought. I imagine there are many equivalent ones. It's about $20.

By the way, when I looked this up I noticed I purchased the one I have now just about 5 years ago. I haven't looked to see if there is an expiration date, but someone in the reviews said it has an "end of life" beeping signal. Maybe it depends on how often it reads CO (more would make it die sooner?).

I am looking for battery-only LP detector too, but so far, I don't think it can be found. I think it has to do with the power consumption. No engineer has come up with one that can run on regular battery for extended amount of time, so it has to be wired. I think some has battery-backup feature, so that may be a plus, but it would be useless if the battery-low alarm goes off after a week when you store the rig, and completely dead when you take it out for a trip.

As for the location of the CO detector, I do not think up high is a bad location. Maybe somewhere closer to the sleeping area, instead near the closet, but CO is lighter than air (~10% lighter), so it will rise so you want to have it mounted high. The LP gas is heavier, due to the larger molecule (compare to N2 and O2 in air), so it is mounted very close to the floor.
