Anyone know how much draw or power the furnace, and more importantly the blower fan use when you run on battery? We are going for a few nights over thanksgiving and expect the night time temp to dip below 10 degrees celcius. So it will likely run, but there are five of us breathing in there!
Thanks
To clarify the furnace will mainly run on propane , like the fridge , but will need power for the igniter and fan

The fan uses plenty of power. Because of all the variations in usage, it is not possible to get a real accurate battery life. Plan on only one day for each battery you have. Might be time for a small generator.

I used to dry camp all the time and found that the heater would run for a day or two depending on how cold it was. Bought a small generator and run it during the night to charge the batteries. As lynnmor suggested, time to get a small generator and your problem goes away.
You can find some pretty inexpensive units at Harbor Freight.

Thanks all! My friend lent me a powerg 1200. I was hoping to get by on just battery, so that sucks! But it is just the one weekend we made it all summer trips running on battery only, we don't use ac or microwave. We just heat the beans over the fire!

Yes, the furnace is a certified battery killer. One battery may or may not get you thru the night. I am going to go out on a limb here and predict that two fully charged group 27 deep cycle batteries will get you thru the night.
And lets not forget the LP/CO alarms that will go off when the battery voltage drops, usually around 3 AM so you have strong motivation to keep those batteries charged up.

After some research I think I'll get a catalytic heater and use that. This one seems to get good reviews:

A byproduct of combustion is water vapor. |

Doh! Back to my wet mattresses problem!! Thanks. It's not often we go when we would need the heater. But that is good to know.
