    What is the difference in blue flame or not
    ByJul 31, 2026
    1 Answer | 
    Answer This Question

    Thank you for your inquiry. The Vent-Free heaters are available in two styles, Blue Flame and Radiant. Blue Flame heaters use convection heat, warming the air around them to heat a space. Radiant heaters use radiant heat, heating objects directly in front of them, and then letting that heat radiate outwars to heat a space. Have a great day!

      If this is set on wooden floors will it discolor the floors because of the heat?
      ByJul 25, 2026
      1 Answer | 
      Answer This Question

      Thank you for your inquiry. As long as proper clearances and proper ventilation as outlined is followed in the manual this heater will not harm your floors. Keep in mind when mounting on feet, the feet do need to be anchored to the floor to secure the heater. Have a great day!

                    Disappointed
                    My garage is 526 Sq. Ft., this unit was easy to install but cannot heat the garage as well as I would've wanted it to. I should have spent the extra $200 and bought a infrared shop heater. I am disappointed with this unit.

                    Easy Pilot Ignition
                    Installed today the pilot gives off some heat. Replaced an old gas heater. Igniting the pilot very easy. Pay attention to hose kit, had to go buy additional fitting, hose is rather wide so it didn't quite have enough space underneath but a quick hack made it work just fine. I will update my revie w if needed. Working as described.

                      I have owned many different brands of these. This is the best so far, of any of them. Smooth flame adjustment. Turn it a little higher and it doubles up the height. Has electronic battery starter. Nice shaped grill and body. Recommended!

                      It lights up the room with a pretty blue flame. It also adds heat to the room. Just like the one I had before...but this one is all Natural..none of the fake stuff...propane.

                      This replaced a 60-year old space heater so the natural gas line was already in place. It was easy to install although I found it necessary to use wood blocking instead of the supplied plastic wall anchors in the drywall. The Instructions were clear and the heater fired up on the first try. It threw off lots of heat but I’ll have to wait for winter for a more thorough review.
