A furnace is only part of the solution though, you still need lots and lots of ventilation.

My Komfort 5er has an Atwood furnace that I used for several years at night with all the windows and vents closed.  No problems with moisture either.   I like the fact that it is controlled by a thermostat and not just "on" with no temperature control.   The big plus is the air inside the trailer has no moisture, as the moisture is vented outside the rig.
 
A RV furnace is the same as a S&B furnace.  All combustion gasses are expelled through exterior vents.  No ventilation required.  It recirculates the interior air around a clam shell that the flame is enclosed in.

I'm considering replacing the thermostat on my furnace with a timer. As I'm more conscious of battery usage than my own strict comfort zone, I really don't foresee any circumstances in which I would set the thermostat and leave it. As it is now, I leave the thermostat on its highest setting but with the unit off, and just flip it on when I want heat, then shut it off after ~15 mins when the van is warm. A timer would do the same job without the need to turn it off.
 
I set the thermostat to my comfort level and leave it there.  I turn it on when cool and turn it off when going to bed.  It may only cycle a couple of times before going to bed.  The ambient temperature plays a roll in how long it runs and cycles.  When I wake, reach out and turn it back on.  I don't have to be the thermostat when it has one built in.  

You could do both maybe.  Set the thermostat to a comfortable temp and run the timer too.  If it warms up before the timer goes off, the thermostat will shut it off and if you forget, the timer will shut it off until you reset the timer.

I thought about that too as I was typing out my post above. Add a timer rather than replace the thermostat with one. That's probably the best solution.

I don't think I'll ever just set the thermostat and leave it though. I think it would run every few minutes.

That all depends on how cold it is outside and how insulated / sealed your van is.  You never know until it is tried either.

I have a similar heater in my Dodge Caravan pop-up, not sure of the brand, I don't use it much, in fact I have never needed it so far but I have started it up a few times to see if it works, I think it is cool that it is thermostatically controlled, I am curious after you use it for awhile what you think of it, how much propane it used and how much power it draws,. Come back and give us an update, on how it is working for you


UPDATE on the furnace!

I've been running the furnace for 8 weeks now.
In the beginning, it wasn't all that cold, just got cold overnight.
The furnace is typically run with the thermostat set at 65 F when I am there, 60 F for sleeping at night, and while I'm away working during the day,
I leave it around 60 F as well.
So it's round the clock operation, I don't turn it "off".

I've been waiting for the colder weather to arrive, and it has! Unfortunately, I say, because I really don't like the cold!
As rvpopeye would say: I yam where I yam! haha

So with my Watt's Up meter connected( it's always connected) and outdoor temps of between 15 F last night, and 20 F daytime today, I recorded the power consumption.

Now, you gotta bear in mind that while I'm living in my cube van, it is a work in progress, and I still don't have an insulated back wall. It's just some OSB and a few studs cobbled together, so there are plenty of leaky areas, you can feel the drafts!
That simply means I am wasting heat, and using more than I should!

As for propane, I have 3 x 20# tanks and 2 x 40# tanks that I am using, but since I started on the propane shack a few weeks back, I've only been filling the 20#'ers because I need the 40#'s empty for ease of lifting etc, while I fit them in the shack.

A 20#'er typically has been lasting me 3-4 days at an average of 6$ per fill.
That is 2$ or less a day, perfectly acceptable to me, as even 3$ a day is still well within what I consider to be acceptable.Over the past few days I have been getting 2-3 days per 20# tank. I'm getting closer to 3$/day at this point.

I also have a powered roof vent that I run a fair bit in the evening, so I exhaust a lot of my heat during those times also.

********
Anyway, the current consumption was averaging 15-20 amps/day, and the last 24 hour period that had an average outdoor temp of 17 F, the furnace consumed 28 amps.
********

For me, as an urban van-dweller, my mobile abode is more of a one room apartment to me, I  don't consider it camping and I want all the amenities of home, just in a small footprint is all.
So this RV furnace is an absolute must for me, and at the current rates of usage/consumption, is still less than I was paying for heat in my former S&B place.
 
nice write up ahh_me2. lots of useful info from real world experience. highdesertranger
 
propane is cheap where you are!!! I was paying 6.00 dollars(sometimes as high as 10) to fill my 5 lb tanks in Ontario over the summer. Thanks for the update, good to know, I figured with my Dickenson P12000 I was averaging 28 hours on a 5lb tank so roughly the same amount not sure of the power consumption and no thermostat. If I had to stay the winter I would also invest in larger tanks good choice on the 40lb ers.

Appreciate the response!

Will write another update after the completion of the backwall, and colder temps in another month or so.

Well to be honest, I get my propane at Costco, and it's way cheaper than anywhere else.
Currently propane goes for 15-20$ for a 20# tank fill, but at Costco, it's only $7.49(Canadian).
Now the Costco I use, changed their propane system about a month ago and now they sell by the litre.
So they weigh your tank, input the Tare weight in the computer, as well as the certification date, bam! Computer fills it and spits out a bill!
So I average $6 a fill now as there is almost always a residual, especially in cold weather.

The 40#'ers will be good once I complete the propane shack, will run 2 of them, should last me at least a week in real cold weather!
 
dang you guys are getting 4.8 gallons of propane for 6 bucks. that's like 1.25 per gal. dang that's cheap. highdesertranger

Hmmm... not sure about that...

My receipt shows:13.435 litres at 0.42 cents a litre, for $5.64

That would be 3.5 gallons.

So...more like $1.54/gallon.

Ok, I guess it was close! lol

How much are you paying in your area?
 
we are paying about 3 bucks a gallon. not sure why but it just went up, last time I filled it was 2.56. but I am in kalifornia, you know we are saving the world here. highdesertranger

Wow, you guys have cheaper gas, but it seems like propane is way more expensive!
That's just plain crazy! Maybe my math is wrong! It's hard to believe we have cheaper propane than you guys.
 
well gas is about 2.50 a gallon here not really cheap compared to the rest of the country. highdesertranger
 
80 cents a litre here, so ...1 gallon US = 3.78 litres x 0.80 = 3.024 /gallon

And the price of gas locally is way below the national average.
 
Gasoline here in Osoyoos: $3.93 CDN/gal and auto propane: $2.80 CDN/gal and 'barbecue' tank propane: $5.40 CDN/gal ..Willy.
 
I think to be fair you have to say that's a very atypical price and in many places you'd pay double or more than that--if for no other reason that most of us aren't near Costcos. I'm a Costco member in the US it's pretty rare for me to be near them so I stock up big time when I am.
