I would really appreciate it if some of the members who use the oil filled space heaters could answer some questions and offer some advice based on your experience. I am fixing to move my snakes into another room so yesterday I picked up a couple of heaters to heat it this winter. First of all, the room that they will be in measures about 13' X 15'. On the heater box it says "For Large Rooms", but nowhere on the box or accompanying paperwork do they specify what a "large room" is. So my first question is, will 2 of these heaters be enough for a room that size, or, is it complete overkill?

The next question is about positioning them. My set-up is going to be 2 sets of shelves with a small storage cabinet in the middle. The total width of everything will be 9'-10'. Would I need to position 1 heater near each end to keep the heat concentrated around the tubs, or, can I centrally locate 1 near the tubs and have the other further away in order to keep the heat more evenly distributed throughout the room?

I have an extra Ranco that I plan on controlling them with. The Ranco is rated at 1500 watts. The heaters have 3 settings, Low, Medium, and High and the wattage for the settings are 300W, 600W, and 1500W. I can run both heaters on one thermostat as long as I keep them on Low or Medium, or I can run 1 heater on High and be right at the limit of the Ranco. It makes more sense to me to run both heaters at the lower settings and still be below the Ranco's limit, or, I can pick up another Ranco if it is better to just run one heater per thermostat. I've never used this type of heater before so I don't really know how much heat they put out at each setting, which is why I need some opinions. Thanks for any input you can offer...
