I discovered some models of propane wall-mounted heaters from Dickinson Marine such as the newport. it is super small and it also has a flame window. I first saw it on a youtube video for Tumbleweed tiny houses. It can work without electricity on the "low" setting which still puts out 5500 btu.
They've also got some great looking diesel heaters. I think that these may be great options for someone who wanted something small and manageable to live off-grid more full-time in a northern climate.

Regarding vent-free heaters: There is no free lunch. Don't use them in anything but fishing shacks or hunting cabins, and then only with adequate ventilation. Besides the noxious combustion by-products, they also generate water vapor, which can lead to mold formation. In residential structures, use only b-vent or direct vent heaters.

The sellers of vent-free heaters will tell you they are about 99% efficient with no off burn. That's like saying you have a drainless sink. I have a vent-free blue flame heater and fireplace logs that are both useless because of the fumes. Intend to install a vent thru-the wall heater that I can actually use.

we installed a HomComfort 21 (which I think was 21,000 btu) in our Alaska 16x20 cabin. A wood stove handles most of the heating but the propane unit is nice when you don't want a full-on fire or it's really cold when we arrive (we're in a couple of weekends a month) and you light everything you've got. It's vented out a 6" hole, with an intake pipe nested inside the exhaust pipe). Seems like a fair amount of heat goes outside, but no fumes at all, good heat inside, lights reliably. Ran us $600 or so, I think. We had an unvented unit. It was a death sentence in the making. Only issue that I may work on this year is a 20lb tank runs low on pressure fairly fast and the heater doesn't get up to full heat. Looking at bringing in a larger tank this winter.

Another nice thing about the NewPort propane heaters made for boats; is they have a fan. It draws very little power and runs on 12 volts. I low amp solar cell and single battery can run the fan and a few lights/ I love the heater.

I, like MtnDon, have one of the 18,000 BTU units he mentioned. It works great.
I knew little about propane before this, but I learned that you MUST have a regulator at the tank (20 lber) in addition to the one at the furnace.
If you have a hard time lighting it, wrap a blanket or bag around the external vent to block the draft, it usually is going the wrong way and blows the flame out before it can light. Then use a small butane torch through the window with the wing nuts and window removed, and it will light right up. Great heater.

I've had two of these heaters over the years. They are actually made by Empire. They are nice little units, but they have one noteworthy design flaw: The burner is not made of stainless steel or cast iron. It is ordinary mild steel, and prone to rust. If the wall vent and the inlet and exhaust pipes are not installed correctly, or if a prevailing wind allows rain, sleet, or snow to enter the burner chamber, the burner will rust, and the heater will eventually fail. If you live in a dry climate, and you are careful to give the inlet and exhaust pipes the correct slope during vent installation, you may get years of satisfactory service from this heater.
