We have this heater installed in a 14 x 16 sun/family room with cathedral ceiling that connects openly to the adjacent kitchen. It's a very nice room setup with one caveat, the sun/family room has an atrium door with side lights that opens onto our side deck....and the DOGS, oh my gosh, in and out All Day. The manufacturers instructions specifically state that you should Not place the heater by an exterior door but I find it works Very well behind the couch, between the couch and the exterior door. We don't have a cold chill running across the floor anymore and when the sun starts to go down and the room begins to cool off, the heater cranks up like it was made for the room. Why we waited 14 years to put a heater in this area is beyond me.
The advertised 'timer' and HVAC sync are useless in our application. Actually, the 'timer' function is not a 24 hour timer and Does Not allow you to set the the heater to turn on and off on a scheduled basis. I believe it's only function is to stay on for a single period of time and turn itself off when that period of time has elapsed. Worse, the controls are electronic which defeats the idea of plugging the heater into a wall timer. So, you must turn it on when you need and remember to turn it off when you don't, like when your leaving the room for extended periods.
The HVAC sync might be useful if the heater were placed in the same area as the thermostat but where we have it placed, the air temp flucuates more widely because of all the window area. But that's why we bought it..to control a local area, not heat the house.
I whole heartedly endorse the UV lamp feature. We use them in my hospital because they work. The fan is noticable only if you are attentive to such things. Otherwise it's something you can easily tune out. And the case is really finished very nicely. It's not furniture so don't expect perfect woodworking but the Tuscan Walnut has a real wood look to it and the color is rich, not fake in appearance.
Finally, this unit will pull some current when in operation. If you have it plugged into a circuit with an old 15 amp breaker, it'll trip..especially if you have any other high current draw appliance plugged into the same circuit and in operation. We have it plugged into a circuit with a couple of floor lamps and the TV. The lamps dim when the heater starts up, but the breaker does not trip.
In our specific application, I rate this unit a 5 without reservations for basic functionality and a 4.5 overall for the addition of advertised 'features' that don't really work well imho, but for which I am most assuredly paying extra. Note: We have only had it two weeks so I can not attest to the units longevity. I will post an update after the winter is over.
