After reading your post again, the most efficient electric heater made, is the oil filled radiator looking heaters. Never fall for the Amish made heaters, or the really nice flicking flame box heaters that claim to heat a 10x10 room for pennies. They leave out some details in their marketing ads. Such as, setting must never be higher than low. And, another great pointer for the oil filled heaters, no risk of fire if turned over or items too close to the heat. Some people actually put a small 12v fan behind them and push the heat around. Works great.
