Wonder what the difference is between a hot box and a super skid? We asked Bill Matthews from Pressure-Pro. His response is copied (with permission) below:

As for the burner efficiency they would be within only a few percent of each other typically in the upper 70-80 percent range (roughly 76-82%). 

The best comparison you made would be that the fuel capacity is diminished for the hot box by 31%.

And for the gas engine by 50%.

One advantage would be that the HBS12V80 has a slightly larger coil and would allow for a slightly. 

Larger heat rise roughly; but would consume roughly .7 GPH more fuel.
