Ok. So the thing you need to know about electric heaters is that we have the laws of physics at play and the laws of physics say that if you use a Kw of electricity hour, you get about 3400btus of heat. It doesn't matter how you do this, one watt will result in that much heat.So, any heater that has elements, or ceramics, or oil will produce the same amount of heat from the same amount of electricity.What you also need to know is that you want about 10 watts per square foot. So, 15x15 room (225 sq ft) you would ideally need 2250 watts of heater.You can't buy portables that big but a 1500 will keep the room warm. I like the Dr Infrared heaters like >>>THIS ONE<<< The price is about right and it is a well made unit with good reviews.Keep in mind that running one on high is going to cost you about 20 cents an hour.I'll be here if you need further help with this issue. Please let me know.
