Heater/Furnace Dry camping

Hello Everyone! I am wondering if I can use my heater with no shore power. I have 2 battery's now. Will not use TV, minimal lights. All I need battery is for fridge, heater, and water pump. Going to Big Bear, Ca and it drops to mid 30's!! Thanks again!!

To view 12V items that should continue to work while NO shore power is available, see 12V diagram items within:

Your furnace will work well on 12V, but be aware that it will not work for long without recharging. There are a lot of variables, like where you set your thermostat, and how cold it actually is. In 30 degree temps one or possibly two nights would be your limit without recharging.

Nice to see you back Clossan! We have used our heater over two nights off shore power once. Have fun at Big Bear. We've only been there to play in the snow in winter. It would be nice to take a Summer trip there sometime

My experience with running the furnace sans shore power is I got one day's use off the battery before I had to switch to the backup.

That was one of the reasons why I just added a generator.

Since I do a lot of camping Nov-March in SoCal I am adding a catalytic heater to my trailer. Uses less propane and no battery power. I should pay for the unit with the savings the first winter..

You can get 2-4 days of furnace use on two batteries, depending on how cold it is. We do it all the tme.
