these are all great ideas for heating... I have studies a bit about diesel heating, as I would love to build a diesel expedition vehicle with all diesel appliances... but cost for cost, it's hard to beat what I have now.
I will look at the propane
'see the flame' heater... that sounds awesome, but I think that for me, the solution is to have an extra battery
, and maybe set them up as duel, if they are both the same age and power, etc. and have about a 1,000 watt generator
. After all, Alaska will be an adventure, but I seriously doubt if I will go too far from the beaten path.
I will be looking for an old gravity style furnace
though. Very interesting!!
While you're in Arizona, don't miss Bisbee & Douglas. My mother was born and raised in that area. Also, the area around Greer brings back memories. I haven't been back since I was a kid. One of my goals is to return!!!
Well okay, here are two more ideas, from opposite ends of the spectrum.
1) Seek out an older, gravity style RV furnace. These came in many of the 1970s campers (eggs, truck campers, pop-ups, etc.), and they use NO electrical power at all. No power draw, no fan noise. They are vented, so no condensation. And they don't suck up your oxygen. I have no idea why these are no longer made, as they work well. (I had a slightly larger one in a cabin.) Probable cost: Less than $200
2) A brand-new, shiny, I-can-see-the-cozy-flame, Sig P9000 propane marine cabin heater. Yes, it's $800, but heck, you were about to buy a special battery bank, fancy charger, and a generator! This has an *optional* fan. So you can run it with no fan (i.e. no power). Also, it's vented, so no condensation/oxygen worries.
Now, couple of factors:
1) It has a chimney. However it's flexible and there are ways to get around leakage (they are used on boats, normally). I believe it is possible to run it out a side wall as long as it still goes up (or, the roof, which is typical on a boat).
2) This would protrude from the wall a bit (I think about 9").
3) These are relatively new, so I have not used one. However, I have used a Sigmar diesel heater (on a boat), and the workmanship was quite good. It also had the cozy flame factor (not to be underestimated, in my opinion), and an optional (and virtually never used) fan.
