    Why doesn’t my heater put out really warm air. It comes on but with it turned up full blast it barely puts out warm air? It never glows red like other heaters do

    Answer This Question

    Thank you for your inquiry. It sounds like the excess flow device on that heater may be triggered. Please reach out to the manufacturer directly at 1-855-663-0660 so we can help get that heater running normally. Have a great day!

      Will the heater reach 140° continuous in a close space to kill termites
      ByMay 29, 2025
      1 Answer | 
      Answer This Question

      Thanks for the question. While the 170,000 BTU Forced Air Propane Heater is powerful and can raise temperatures quickly in enclosed areas, it’s not designed or rated for pest control applications, including achieving and maintaining the 140°F continuous temperatures typically required for termite extermination. Using it for that purpose raises safety risks like overheating, improper ventilation, or even fire. We strongly recommend using equipment that’s specifically designed for thermal pest treatment.

            Can this be used to kill termites in a 250 square feet room?

            1 Answer | 
            Answer This Question

              What is the max temp that this unit can obtain and maintain in a 24x20 insulated shop building?
              ByAug 24, 2024
              1 Answer | 
              Answer This Question

              Thank you for your inquiry! The temperature of the unit's high limit switch will shut the heater off once it reaches 240 degrees. Because of this, the achieved room temperature may vary. Hope this helps!

                  Can I use Forklift Propane Tanks on this unit
                  ByJan 19, 2024
                  2 Answers | 
                  Answer This Question

                  I'm using a 33 lb forklift LP tank on mine. Works great. Just be sure to use the vapor only port/valve. The fitting and valve for the forklift supplies liquid LP. Forklifts have vaporizers to convert the liquid to a gas as well as the proper regulator.

                  By|Feb 20, 2025

                    Hi Vito. According to DeWalt, the minimum recommended LP tank size is 40 pounds. This heater uses a standard POL left hand thread coupling. Please let us know if we can be of further assistance. Rick_HD_OC

                    Shame on Home Depot
                    The specs show "Indoor/Outdoor". The comparison shows this heater "Indoor/Outdoor" Nearly every single comment says outdoor only, do not use indoor,etc... Please correct. ps Honey I will use indoors, if it doesn't workout, this should strenghten your case

                    Thank you for your review and feedback. Though the heater is not safe for use in a home, these are commonly used indoors in ventilated garages or construction sites. Enerco

                      Got the DXH90FAV today, 02/2020. Out of the box it worked flawless. I've had D Glo's in the past....
                      Got the DXH90FAV today, 02/2020. Out of the box it worked flawless. I've had D Glo's in the past. When I had to put my third thermocouple in my D Glo this past week (third one this winter), I decided to pursue something that doesn't require as much attention and money poured into it. Never did I realize what a piece of garbage my D Glo was until I fired up the Dewalt. Mind you, this particular D Glo was only two years old. The Dewalt, (which is made by Mrs. Heater's husband by the way), runs unbelievably quiet, and not only is it quiet, it burns with a blue flame. The D Glo's always burnt with a yellow flame. Blue flame translates to more heat from your propane dollars and also more heat appreciated from the unit. I can actually feel the heat from this thing ten feet away, on low, where with the D Glo I had to be within three feet to feel anything. My building is 24 X 32, un insulated . Today in Ohio we were in the low 30's, after ten minutes my building was at 60 degrees with the Dewalt running on low. This thing is built so much better than the D Glo, as it has the split barrel design which provides faster easier maintenance, (which I hope I don't need for a while). The fasteners are threaded into thread inserts rather than the D Glo design which is to thread the fasteners into roughly 20 ga. sheet metal. I've had to take apart my D Glo's so many times over the years to replace thermocouples that half the fasteners are stripped in the sheet metal. Spent a bit more money for the Dewalt, yet hopefully the savings from not constantly replacing thermocouples combined with the savings from actually burning with a blue flame rather than yellow will pay off. If time altars my opinion of this heater I will post an amendment to this review. So far it appears Dewalt lives up to it's time honored reputation.

                        Heats well and it is quiet. I was disappointed with the way it turned on and off. It’s a piezo starter and you must turn the gas tank off before removing power. There is no gas shutoff on the unit and it will continue to burn if unplugged first.

                        Stopped working after 1 day. I used the propane hose off of it to get another running. I would have returned it.
