The low setting is just 375w! How long can you run it without draining too much of the Battery?I use the vornado VMH10 heater in my van whenever I feel I can spare the power stored in my batteries. I find I can turn it on the the morning or evening to take the edge off the cold. It's a great little ultra quiet heater that does well. I can store it in the shelf above the driver cab too as it's pretty small. I have a Webasto I use when I can't spare the power, but in actual practice, probably about 60% of my heating BTUs come from my little Vornado heater, although I tend to avoid particularly cold climes. I have 200ah lithium storage and 400w solar.
