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 10° but would consume roughly .7 GPH more fuel. 

8012 pro-35 HG 2.8 GPH diesel (approx. 170) (12-gallon tank approx. 4.28hrs)

Honda gx690 1.8 gph gas (12-gallon tank approx. 6.66 hrs.)
