Can you use an oil lantern inside of a wood stove for all night heat?
Can you place a lit kerosene lantern in a wood stove that has a chimney? In a relatively small room such as a truck camper, would you be exposed to carbon dioxide or would it go out the chimney as if burning wood?
Generally speaking, it’s a bad idea to use fuels in things not meant for them. I don’t know of a lamp would produce enough heat to push CO /CO2 out the chimney- but it’s very likely the lantern is not going to be adequate for all night heat.
It’s also a bad idea to leave lanterns running unattended- though depending on the stove this may be mitigated, it’s not particularly safe.
IMO? If it’s a matter of staying warm, you’ll be better off with plenty of warm blankets or sleeping bags - remember to layer them on top and bottom.
It helps keep your feet warm for a little while, but honestly? The water bottle is most useful for something to drink when you wake up- keeping it from being totally frozen.
I'm sure a purpose made item has been invented by now, but I've had good results filling a large steel canteen with boiling water then putting it inside two or three thick wool socks and having it still steamy when I open it in the morning.
They make little pillows filled with seeds or cherry pits. You can microwave 'em to get them hot. Love those things. Would recommend the seed filled ones over the cherry pit ones. The cherry pits feel coarse.
