Hmm, I agree totally with MI WRT the
general wisdom of un-vented propane heaters.
OTOH, GS has mitigated that risk to a great extent:
1. Leaky RV
2. CO detector
3. O2 sensor and auto shut-off if O2 dips
4. Leaves a small window vent open to outside
Not the route I would take(1), but GS is all grown up and has no minor children dependent on him.
As far as "It's the attitude you express to others..." I think MI is way off his meds.
MI's attitude is much more poisonous and likely to get one in trouble IRL than is GS's supposed insouciance, especially since, "...others who may not realize the dangerous of carbon monoxide that's the problem," would have to ignore every other post on this very thread speaking to the dangers of CO in addition to GS concrete steps addressing that risk.
Misanthropy trumps an elderly person's greater risk-insensitivity in destructive consequences every day of the week and twice on Sundays.
Anyways, this has been discussed on THR before and every time the risks associated with non-vented propane heaters has been brought up. Anyone who goes out and offs themselves with a heater like GS's after reading any one of those threads does so in the face of near-complete awareness of the risks involved.
(1) I'd vent to the outside anyways. I have minor children and my tolerance for risk where they are involved is lower than GS's toward his own self and his wife. Risk-sensitivity naturally fluctuates with age, life circumstances, and other factors. I'm not going to excoriate someone who makes an informed decision, looks at the bottom line, and comes to a different decision based on a different risk sensitivity.
