Pros
  • Big 150,000 BTU output for barns, warehouses and large job sites
  • Shuts the gas off if the flame goes out, and cuts out if it overheats
  • Split barrel opens for cleaning
  • Hose and regulator come in the box
Cons
  • Only turns down to 110,000 BTU, so it can be too much for smaller spaces
  • Needs a 120V outlet or generator to run
  • Construction heater only, for well ventilated spaces, not living areas
  • DeWalt no longer has a product page for it, and no coverage figure is published
