That is a very good point.
To run mine, I invested in a couple of good deep-cycle batteries.

You then have to have a plan to maintain the batteries.
For me, it has been worth all the bother.
The batteries are now 5 yrs old and they have provided power
thru numerous outrages and run lights and fridge besides the
furnace as needed.

How long can you run off of the batteries? Can they be charged with your
car?



I have 2 deep-cycle in parallel. They will run the fridge
for a couple of days. The oil furnace I ran for shorter periods
so I don't have a good figure.

Yes, you could charge off the car alternator. Might want to
put an ammeter in the circuit to limit load on the alt to some
reasonable figure/
