We don’t own any heaters and never need such things. Any outdoor cooking has any smoke and fumes going away from the house as we are all very sensitive.
It turns out my D has a CO detector in her apt. According to her, it talks annoyingly.
Some CO detectors have a display of the amount of CO detected. This can be useful for noticing a non-zero CO level that is not high enough to trigger the alarm. Noticing such a thing could allow for repairing a defective device before the problem gets bad enough to cause a situation dangerous enough to raise the alarm.
I am in the process of selling a house, and just today had the town fire chief inspect the new required CO2 and smoke detectors that I installed last weekend. You can’t sell a house in MA without that inspection certificate and they now require the 10 year sealed battery smoke detectors and CO2 detectors on every level of the house. We also have one in each bedroom in our home.
^^Ditto in WA. I think CO detectors (not CO2!!) need not be hard wired, but smoke detectors do.
HA! @BunsenBurner Guess it’s obvious that I’m not the chemistry major in this family! LOL
If the button you push still beeps on the smoke detectors does that mean they still work? Or do you try putting a candle underneath them? Mine are more than 10 years old.
Ours was 15(?) years old and went flaky. We bought a new one and ran them both for a while just to make sure the old one’s alerts were false alarms.
