The only way it heats the cabin is by radiant heat. Basically the thing gets hot and then warms the air around it. So it has very little effect on cabin humidity.
Yep. I was simply making note that the only systems that actually dry the air rather than just heat it need to draw air in from outside the cabin for ventilation. There may be people following this thread that are deciding what type of heat to install that information may be useful to.
