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.
The best-selling electric cars are the Nissan Leaf and Mitsubishi i-MiEV. Other electric cars from traditional car companies include the Smart ED, Renaut Fluence ZE, Ford Focus Electric, BMW ActiveE, and Honda Fit EV. The most successful all-electric car company is Tesla Motors, which is to say it only took 10 years to make a profit. Hybrid gas-electric vehicles such as the Honda Insight and Toyota Prius (among many others) continue to be popular in part due to their comparatively lower price than most fully-electric vehicles.

An electric water heater in a hot tank is called an immersion heater and many of those run at 3 kW with a thermostat to control the max temperature. Power showers use a type of water heater that heats the water at the point where it is used, without a tank. They run at 6-8 kW and are also controlled by a thermostat.
The wattage of electric base board heaters does not change because the thermostat is set on low. The wattage is a fixed value on the heater because of its internal resistance element. The thermostat set on low shuts off at a lower temperature than a thermostat that is set on high. It is the time interval that governs the amount of heat that the heater produces when the thermostat calls for heat. Once the room heats up to the temperature that the thermostat is set at, the heater shuts off. The thermostat is just a temperature switch.

Electric heaters are a popular choice with people who are looking to reduce home heating costs. Many people spend the majority of time in one or two rooms. Rather than turn up the thermostat which would result in higher overall costs, they choose to purchase an electric heater which can warm up a small area for much less.
