Any heater that has the Energy Star label will be very energy efficient. The Honeywell eco line, for instance, are very energy efficient.

Efficient, yes. But a poor choice for a heater. It's just a marketing gimmick. Every electric heater is nearly 100 percent efficient. Efficiency is a term not understood by many. Energy efficiency - useful work per quantity of energy. In other words, What is the job of an electric heater? To make heat. How much of the electricity fed to the heater is turned into heat? All of it. That makes it 100 percent efficient. In contrast an incandescent light bulb is only about 5 percent efficient, only 5% of the electricity fed to it is converted to light the other 95% is converted to heat.

Nothing or anything that converts energy is 100% efficient because as one form of energy is converted into another form, some energy is lost in that of heat, sound or other factors. The most efficient form of energy is the fuel cell as it converts chemical energy in electrical energy directly but still it's not 100% efficient. A2. I think that an electric convector heater would be 100% efficient, as it has no moving parts to lose energy through friction, all the electric energy absorbed in the device is emitted as thermal energy.
