I would suggest that you do a little research on the enemy (CO) to learn the character traits and properties of this deadly gas at various temperatures. Someone please correct me if I'm wrong, but I believe CO is typically more dense than air, thus creating a sinking gas that accumulates at the floor level and builds from that point. Usually you would want to place a detector near the floor, to alert you of the danger prior to the a high level reaching your bed elevation or second floor. I would hate to see someone doing the right thing with purchasing a detector and then installing in the wrong location beside a smoke detector on teh ceiling. Good luck and stay safe.
BoozeHunter, You are incorrect.
Carbon Monoxide is not heavier than air. Carbon Monoxide has a weight almost the same as air.
Thus, it will rise and circulate throughout your home with the warmer air.
Please follow the recommended manufacturers instructions on the proper placement of your CO detector.
Here is a link with some additional information:
My home, I have 2 CO detectors.
I also have an oil furnace as my primary heat source in my basement with forced hot water baseboard throughout my home.
I have 1 CO detector mounted on the ceiling in my basement at the very bottom of the stairway.
The 2nd. is located on my 2nd. floor. It is mounted to the ceiling in the hallway in front of the bedrooms.
