Heating with propane directly with catalytic heaters cause moisture build up.
Heating with wood makes a nice dry environment inside the bus.
Here in winter, moist heat from a propane catalytic heater would be almost useless. The amount of heat needed causes so much moisture buildup, clothing, shoes, ect will not dry out.
Wood stoves dry heat is perfect for drying out in winter, and preventing moisture from condensing on bedding, clothes, walls, ect.
There is always something around to burn. Trash, fallen branches, grass, pallets, coal from the river bank, ect.
When your propane tank is empty, you have no heat.
I like propane for long term storage, and cost.
However for point of use, wood is a winner without question.
If using propane indirectly, it works great. In propane furnaces, hot water tanks, and boilers, the moisture from the propane never reaches your living area.
