Space heater while in storage?

The next few days the temp is going to drop to between 15-25 degrees overnight and mid to high 40's during the day. I'm wondering if I should plug in a space heater and set it at 55 degrees to keep the pipes from freezing. I haven't winterized the trailer nor will I have time before the freeze starts (normally we only see temps in the mid 30's.

I have no shore power where it is stored so I would be depending on my 2 6 volt batteries plus a single solar panel system to handle the load from Thursday to Tuesday. Do you think would be ok?

  • Forget counting on the batteries to power a space heater. You will get about 30 minutes of heat before dead batteries. Forget about using the batteries to power the furnace. You will get about 24 to 36 hours before dead batteries.

    Just spend the 30 minutes and winterize!

    X2. I can do mine in less time than that.
  • The BEST option is to winterize (takes maybe four times as long as dropping off a space heater and getting it running), will cost about the same and be MUCH safer for your RV. You can blow out lines in about ten minutes or do a replacement of antifreeze in about the same time.

  • Hi Eyetattoo,

    Yes, the furnace draws at most 9 amps, and produces 30,000 btu's. A 1500 watt heater may draw 150 amps, and produces about 5120 btu's.

    I have 875 amp-hours of battery bank. That means I could run a 1500 watt space heater for perhaps 2.5 hours, before I hit 50% state of charge.

    Yeah I was considering a electric heater.

    So the furnace will use less power than the space heater?

  • if you don't have shore power there is no way in haddes you can run an electric space heater. and if you think two 6 v's will power the furnace for 4 days then you are again wishing for a miracle. You should have winterized long before now. I suggest you run it for one night and get it winterized tomorrow with out fail or you will need to replumbe the TT next spring.

  • Hi,

    Are you talking an electric space heater? If so, all all you will end up with is a set of extremely dead batteries.

    I'd set the propane furnace as low as it goes, if I were not prepared to winterize.
