I bit the bullet, in no small part to Lane End's donation. Attachment: Screenshot_20211016-152052_Amazon Shopping.jpg I sent LaneEnd an analyzing, desulfating charger, to help him keep the batteries he is keeping maintained, and recover any new ones he might get so he can use them.

I have an Espar Diesel heater in my van. I've been told that an insulated @R5 van of 90 sq.ft. will burn about a gallon of diesel a day on a 20°F day, so these heaters are sippers. They don't use much electrical power at all, only when igniting and once lit, will raise and lower the fan to maintain temperature. The cheap Chinese $150 versions should have similar controls. I kicked on on today, while working inside the van. Nice dry, well moderated heat.
The other big point, which you already mentioned is the moisture issue with a propane heater, unless you go for the higher end units that vent outside, but they are $6-800.

EDIT: Oops, too late, but diesel was the right choice.

Why is a wood stove a problem? I have a free horse trailer that the fiancee and i are converting into a camper this summer. I was figuring on a rocket stove kind of a thing, and i was tossing around throwing a water jacket around it so i can get a more even transfer of heat(when burning let it thermal-siphon) . I'm not going off of anyone's plans or ideas, just the first thing that came to my mind.
The simplest solution would be a pony keg wood stove inside a water filled stainless keg jacket, a little bulky compaired to what i was going to do, but you could pipe that heat all over, and aside from some stainless welds it is pretty simple to build.

shaggy wrote: Why is a wood stove a problem? Fuel supply. Burn time. 1 lb wood = 7,870 BTU 1lb propane = 21,500 BTU 1lb diesel = 19,857 1 gallon diesel = 7 lbs. = 139K BTU (139K/7=19,857) So, you need 2-3x more wood, per lb, than other fuels. Also, diesel heaters and catalytic propane heaters are insanely efficient in terms of how much fuel goes to producing heat. Wood burning stoves are pretty inefficient and you lose a ton of heat through the chimney.

I’ve never heard of diesel heaters exploding. Just saying…

Going off the first thing that comes to your mind is not the best way to make decisions, especially if someone else is counting on you…

Amazing innovations are bred from people looking outside the box and trying things out. Don’t listen to the hate shaggy…. You do you.

We have propane (and a heat pump) HVAC FWIW, the energy density is great IMHO. Really clean. Diesel is a bit messier, just as a point. Both - as a liquid, and mostly oxidized in combustion.

Was just suggesting a little research wouldn’t hurt, especially if someone is counting on you out alone in the cold…

Was just suggesting a little research wouldn’t hurt, especially if someone is counting on you out alone in the cold… It's good advice from both of you, I havent bent the first nail on this yet, just spitballing which is why i was asking. I hadn't considered weight of fuel, i like being able to scavenge fuel also wood will never fail on you. Oh also, i'm a toolmaker, worked on $1m+ street rods and have a pretty wide set of fabrication and engineering experience, so it i'm taking on my project with good knowledge of how to design and build stuff

If you're planning to live in the woods... Get a wood stove...
They do make wood pellet stoves with automatic hoppers if you want to go all night without having to stoke it...
The problem with wood stoves in small spaces is multi-fold.
The stove either has to be small, in which case you won't have enough space to keep a long burning log... or it's too large, and will burn you out of your space...
If you think of a buddy heater... which puts out 9K BTU on high.....a 20lb propane tank, FULL, weighs about 37 lbs..and fits in an area of... what, 12x16?
So, we know that propane is 21,500 BTU per lb, and * 20 lb (It's actually around 4.75 gallons) = ~430,000 BTU
So, on high....which I've used to heat an uninsulated box that was 20x8x7.... that means you'll get (430,000 / 9,000) 47.777~ hours....and on low, which I wanna say is 3K BTU.... = ~143 hours
So, on low, I have enough fuel to run heat for about 6 days. How much space would 6 days of wood take up?
You can make a small wood stove out of an ammo can, for emergencies... which is what I plan to do.... :D

An old timer once told me, wood heats you twice, once when you cut it and the second time when you burn it
