This is a adequately designed unit for outdoor use, but puts out a lot more light than heat. I bought this to use on my screened in patio. It is mounted above the sliding door, pointed at my spa. My hope was that it would provide enough heat that one could stand under it while drying off from the spa during chilly weather, but it just doesn't put out that much heat. My propane patio heater is far more effective, if something of a bother to light. I didn't expect it to heat an area - just people standing under it for 5 minutes or so.... disappointing that it can't even do that.
I have two other issues: 1) It makes the entire room glow bright orange - this puts out a lot more visible light than I expected from an "infrared" heater (you could read by it!) 2) There is no provising for a switch on the heater or with the cord. You must turn it on or off by plugging it in. There is also no thermostat or timer - together these reresent significnat shortcomings for a heater of this type.
I would recommend looking at other options for spot heating. This is worth a try if it looks like it will meet your needs, but be aware of its limitations. Keep in mind that it must be installed in a sheltered enviornment - it shouldn't be exposed to rain or snow.
