Sorry for trying to help.
With Proper air flow, a sunflower heater will do nothing more than keep you warm.
A buddy heater without air exchange will slowly build up toxic co gas but will shut off before being fatal. Use of vents and air exchange recommended.
I use a CO detector…I imagine spell check changed that to co2 for me. Just to clarify.
A lantern can also kill you without ventilation.
A buddy heater is producing the same co other heaters produce.
You can be a total idiot and not die using a buddy heater because it’ll shut off for you. Probably not a good idea to continually sniff the co, but I’m no Dr.
You can still be an idiot and not die with a sunflower if your smart enough to introduce significant air exchange… As suggested.
I’ve also mentioned that I’ve been THAT IDIOT without air exchange once, and will never make that mistake again… That mistake being air exchange… Not the sunflower.
To each their own solution.
I’m significantly more worried about my safety when driving on a highway than I am sleeping in my well ventilated shack where I am in control of my destiny. Not so much on the hwy with everyone else, many of which with their phone in their hand, tired, drunk, or just not observent.
