The amount of space the Cubic Mini will heat in a skoolie depends on your floor plan. If you have a very open floor plan, the Cubic Mini Cub will heat 100 – 200 sqft and the Cubic Mini Grizzly will be able to heat 200-400 sqft.
However, if your Cubic Mini will be secluded into the front or rear of the bus and the floor plan is sectioned off between the halves of the bus, the Cubic Mini wood stove may not be able to heat the entire school bus conversion and you may experience dramatic temperature differences in temperature in each half of the skoolie.
