One of the main differences between blue flame and infrared heaters is that infrared heaters are more targeted, so users feel the heat if they stand directly in front of them. Blue flame heaters work better in insulated rooms, while infrared heaters work better in uninsulated areas because they heat objects before the air.
For people who want to feel the heat as soon as possible, infrared heaters are more effective. Blue flame heaters work better if a person wants to heat an entire area. Because infrared heaters produce more direct heat, they can damage furniture and other objects more easily than blue flame heaters.
