Michael,

Since there are no by-products produced from electric heat, it is virtually 100% efficient. (Save for the power used by the fan) This means that no matter how they "fancy it up", 1 watt of electricity equals about 3.4 btu's. The most a standard 15A outlet can give you is ~5200 btu's. So the output of the $600.00 "Krystal" will be no more than your exisitng $20.00 heater. And it will use the same amount of power.
