A question for those of you with electrical prowess

Deleted my post so this thread can stay on track. Thanks to people who gave me good info!

Even with a second battery electric heaters pull a TON of power. running AC you'll need an inverter of decent size, say 2000 watt,breaker, etc

Hey t.ferguson, if you can't fix the van's heating system, I recommend buying a heated seat cushion (example here : amazon.com/Wagan-IN9438-Hea…).

That option is cheap, requires no electrical intelligence to install, and won't kill you if you keep the windows rolled up.

The problem with it is that you should only use it when the car's engine is on. Electrical heating, of any form, will kill your battery after just a few hours.

I don't have any experience with this aftermarket heater ( flex-a-lite.com/mojave-heat… ) but it seems like it might be a solution for some people.
