According to my so far limited research, a radiator can reach up to 200-230F or 110C. Spending 8 hours outside in 100F heat can give you heat stroke so surely this method would cause death via heat stroke in a few hours? I realise that heat stroke isn’t the nicest way to go but if you could fall asleep then it would be relatively painless yes? Also would having the radiator on this high cause a fire? If I was going to do it I’d probably put the heat up to 50 or 60C so it wouldn’t be that unbearable.
Any comments about this method would be appreciated.
