Clark it depends on what you are heating. The one in my bedroom I set at 1000 (250 & 750 post) in the bathroom I used the 500 watt, in the Living room I used the 1500 watt.. if that is any help.. You need to consider total draw on those really cool nights when you don't want to run the furnaces...

Okay, this one is in the living room, which is the biggest space in the coach, so I've got it on the right setting then.....thank you very much!
