well i see your point on some issues but its hard to heat large space with a 1500 watt radiator heater and you are still running fans to evenly distribute the heat which is more electricity to run. force air heaters dry out the air and have to run all the time and still the heat rises to the ceiling with it still being 1500 watts if it heats the room evenly faster than a radiator heater its not running as long which cuts down on electricity so to achieve the same effect you have to run half as long and not always running fans to move the heat so in turn the high cost could pay for it self in months. now i am not talking from experience but if it works like stated i dont see a good comparison to radiator or force air heaters. its kinda like those energy efficient light bulbs more expensive to purchase but cuts electricity use in half or more so you really save money. Just a though. Well I thought it was neat but thanks for you views keep them coming i would like to see if anybody sees it my way.
