How do I determine the fuel type to use (diesel, LP or natural gas)?

Diesel units are the most portable, produce the most heat are a the least affected by extreme temperature. Gas units can be considered when a suitable gas supply will be available at the site.

How do BTU’s, Airflow (CFM) and Static Pressure (w.c.) effect my decision regarding what heater to purchase?

BTU’s determine how much heat will be supplied and thus how large an area can be heated. Airflow determines how well the heat is distributed and how well the heater can dry the area.

Static Pressure determines how easily or far you can send the air especially important with long ducting runs.

Recirculation gives you the choice of heating outside air or recirculating the heated air from the space back to the heater for re-heating which can reduce fuel consumption significantly.
