I need to replace my propane alarm.
Some models now are 2-in-1. Propone/CO (carbon monoxide).
I think CO is formed when fossil fuels, like propane or natural gas, are not burned completely. I think.
Is there a need for a CO alarm in my unit if I use propane for heat, stove, and sometime fridge?
Or just propane alarm is sufficient?
The biggest CO hazard in your trailer is your furnace
. When functioning correctly it encloses and contains the combustion product in the heat exchanger and vents them outside, but hot combustion gasses are corrosive, bouncing down the freeway causes mechanical stress, and either of these two things can damage the exchanger so it leaks
combustion gasses into your trailer's interior.
Is it likely . . . no . . . would I spend the extra $20 or whatever on a fire/CO detector? Yes, already have.
