We have used an EdenPURE GEN3 Model 1000 Quartz Infrared Heater for 4 yrs when we "snowbird" in Fl the months of Dec, Jan, Feb and part of Mar. In those 4 winters, we have used 1/2 or less of a 30# cyl of propane for heat. I made a table top for our heater that has a lamp on it. It does not get hot, but did a wonderful job of heating our entire 31' Flagstaff 831RLSS trailer. I made a new table top for it so it would match the woodwork in our new 12 Flagstaff 8528RKWS 5er and expect it to heat it just fine also. I have added an auxillary switch to the propane furnace fan to use with the Edenpure to help circulate the air thru the floor vents. When we had a cat that traveled with us, she would get on top of the Edenpure and sleep until I installed the table top on it. It is safe around kids, altho pricey, we like it.
I also added a separate outlet & circuit breaker strickly for the heater.
