As it gets colder and we look for ways to keep warm, bear in mind that using the oven or stove top for heat is not a good idea. There is no venting on the stove or oven and if you use it for long periods of time you will fill the living space with carbon monoxide. (This is not good)
The same with ventless propane heaters. They have an oxygen depletion sensor so they will shut down when the oxygen level falls below dangerous levels. (Again venting combustion products into your living space is not good)
Be careful with propane when trying to stay warm
