Pros
  • Runs from an ordinary 20 lb tank, where bigger torpedo heaters need 40 lb or more
  • Shuts the gas off if the flame goes out, and cuts out if it overheats
  • Quieter than a standard torpedo heater, by Mr. Heater’s claim of 50% less noise
  • Comes with the 10 ft hose and regulator
Cons
  • Needs a 120V outlet or generator to run its fan and igniter
  • Construction heater only: not for homes or RVs, and only in well ventilated spaces
  • No thermostat, so you adjust the heat by hand
