Need advice on propane heaters

Should I permanently install a propane heater in my 2006 16 foot scamp? I can buy a new one from Scamp for about $400, but would still need to pay someone to install it? It's suburban nt-12se furnace.

I have been reading all the recent posts about heaters. I miss having a heater. I could get a portable one for much cheaper, but then have to leave windows open and worry about carbon monoxide buildup.

I would like to boondock more. It can get cold in the spring or fall, and having heat would be nice. If I put in a built in one, how much do I really have to worry about using up the battery? Is the suburban a good one, or should I look at another brand?

It would be so much easier to just use electric heaters, but we liKe to boondock, especially because of four dogs.

Thanks,

Ruth

I'd get the Atwood Everest #8012 with the lowest amp hour draw available today, 2 a/h.

The current used by the 8012 is about 2 amps (2A)... not "amp hour" or a/h (which would mean "amps per hour").

I agree that this Atwood is a good choice. It has lower-power fan because it is not for use with ducted systems; since our trailers typically use furnaces without ducting, there's no need for the higher power consumption (and more fan noise) of furnaces intended for use with ducting. I remember the 8012 spec at 1.8 A, but even if it is then "2" is close enough.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

I'm a catalytic heater user so have no personal experience in this department, but my observation as a member of several forums is that there's a general consensus that furnaces are indeed major limiters of boondocking time due to power draw from the battery. Most users report about three days of battery life in heating season, depending on usage of course, and on other demands in the system.

As Jim said, some furnaces are a little better than others, draw wise- the model you're looking at differs from the one he suggested by about 1 amp hr.

When a 12v " 2 amp draw" or "current used" item is listed, that means it takes 2 amps per hour to keep it operating, thus amp hour is an indicator when calculating your battery reserve which is measured in amp hours.

Which calculates to a 33% savings or you could say the other model draws 50% more than the Atwood.

Jim, please just leave that "per hour" out, and you would have it just right! The ampere (or just amp) is a rate unit - it already has the element of time in it. That's all I was suggesting - just use the units of measure of properly, to avoid confusing the information.

The corrected version of Jim's post would be:
When a 12v " 2 amp draw" or "current used" item is listed, that means it takes 2 amps to keep it operating, thus amp-hour is an indicator when calculating your battery reserve which is measured in amp-hours.
This problem comes up routinely, and greatly increases confusion compared to simply using the units of measure properly.

I guess my question would be, if the heater operated for 30 minutes avery hour, am I drawing 1 amp or 2 amps from my battery reserve every hour?

"that means 2 amps to keep it operating" but for how long???? clear as a bell to me now as to what the furnace he is recommened will use in a hour of use. Not!

2 amps for a half hour uses 1 amp-hour of power from the battery.

That is what I thought and if it ran for an hour, 2 amps. So when calculating your battery needs you need to time as well as draw. either way, I think Brian and I were saying the same thing, you say tomato and I say tomato

Yes, it is rate x time. Like MPH x hours = distance.

Thank you Tom for a much simpler explanation for those of use who are electrically challenged & little interest in changing that.

Slightly off center of topic, I'd like to have a repair manual or even a parts schematic for an Atwood 8012-11. Went up, up and away in a ballon and to the top of Everest and in my Burro but I can't find information on this furnace. The Atwood site PDF containing furnace info stop at p. 27 but according to its index the 8000 series info starts on p. 39. Some fun! Mine is out in the aisle right now. I'm going to blow out the squirrel cage to see if it's not throwing the sail switch but I may have to take to dealer. Chance to clean up Scotchlokbuttcon hell in there; apparently been out before for its annual checkup which is encouraging, I think? Atwood has the nerve to state that they can be serviced in place. Perhaps they mean a burner diagnostic from the front? A ferret with a stubby would have trouble servicing it in situ.
