Thanks for responding. I’m planning on buying some chemical hand/body warmers. Would putting a canister near one of them help heat it up? How safe would this be, considering that you’re supposed to keep them away from heat?
I expect the temperature to be around 10-20F during a snowstorm, maybe below 10.
How would you store them if you were in an apartment? All of the safety notices I read say not to store propane tanks inside.
