http://www.firepitsoutdoors.com/Halogen-Patio-Heaters Halogen patio heaters are electric patio heaters but they are much more efficient in the way they heat. Halogen patio heaters heat only the objects around them where as conventional patio heaters also heat the air. That’s what makes these heaters very efficient outside on the patio. On a windy day these halogen patio heaters will keep you much warmer than those old conventional electric patio heaters
