Pros
  • Turns down from 90,000 to 50,000 BTU to match the weather
  • Shuts the gas off if the flame goes out, and cuts out if it overheats
  • ETL certified, by DeWalt’s page
  • Long 20 ft hose lets the tank sit well away from the heater
Cons
  • Needs a 120V outlet or generator to run
  • Construction heater only, for well ventilated spaces, not living areas
  • DeWalt’s own pages and the Amazon listing disagree on its output range
  • No thermostat, so you adjust the heat by hand
