Been reading up on diesel heaters and they have some good advantages over propane heaters: produces a lot of heat, dry heat, they don’t use a lot of fuel, and they aren’t that expensive.
They require a power source to ignite and pump the fuel as well as to run the fan. I think that it would be a great addition for ice camping but am not sure how big (amp hours) a lithium battery I would need to run it for 24 hours. Anyone have an idea?
