Hi, all graduates and experts here. Being a civil engineer, I was about to create the plan for my new home in Ontario. When I consulted with my fellow engineers, they suggested having carbon monoxide detectors, inside my house as a part of increasing the security. I have already decided to place some home monitoring devices in my home so that I can monitor the safety even if I am away. I really doubt, what is the actual need of placing a carbon monoxide detector. Where does this much amount of CO come from my home? Edit by mod: Deleted link to blog. I read this informative blog suggested by an engineer. Initially, I had a misconception that the source of CO is only the smoke from the vehicles. But I realized that the woodstoves and fireplaces, charcoal grills, gas stoves, gas dryers, fuel-fired furnaces, and gas water heaters in our homes also release CO, which will be inhaled by us. So, I have decided to place a CO detector in my house and can you please help me finding a good one? How do this work and In which all places I can place it? Thanks in advance.
