It is difficult to believe that anything has a 100% efficiency rating, even an electric heater. Electricity is very good at producing heat. Any loss of efficiency would be in how much heat is lost to the surrounding equipment and building structure in the immediate vicinity of the heater, which may be in the basement, as opposed to heating the air in living or working areas which is probably what you want.
Electricity is very expensive when compared to other forms of heat, such as natural gas.
Yes, an electric baseboard heater can be installed under a towel rack in a bathroom.

copper?
you want an answer? I will give it to you. You will not find a quiet-running, efficient, electric heater with a fan because the gas and electric companies will not allow you to have one. No lying. I just spent an hour plus trying to find one (in august mind you) with no success. This after a year of living up north again and going through 6 different heaters, none of which worked the way I wanted them too. Now I come on this site and give my facebook info only to get errors when trying to abort. Well listen to this you gas company turds . . . I just came up with the best idea for an efficient, reliable, quiet operation fan driven heater and I am going to build it. Questions? Call 954-937-2499
The resistance that controls a heater motor in the electric system .
The main feature of an efficient electric heater is, that is used up to 30% less engery than a conventional electric heater. This reduces the cost of the heater.
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.
No, an electric appliance will not work without electricity.
No, that is perfectly fine as it is an electric heater, However if you had water near the electrical appliance, that would be dangerous.
Normally NO
Only if you're referring to an electric heater ... since all loses are also heat. The real world answer is no.
One of the most energy efficient water heating methods is the heat pump water heater. This method is proven to be two times more efficient over the standard electric water heater.
No, electric heaters are not 100 percent efficient. While they convert all the electricity they consume into heat, some heat can still be lost through the material of the heater itself, especially if it is not well insulated. Also, some heat may escape into the surrounding environment instead of heating the intended space.
An electrical heater can be 100 percent efficient because all of the electrical energy provided to the heater is converted into heat. This occurs when there are no energy losses due to factors such as resistance in wires or inefficient components within the heater.
The Fahrenheat Electric 5120 BTU Baseboard Heater is very energy efficient. Because of its "baseboard" design, it is not necessary to use a powerful to disperse the heat. It uses natural radiance, which saves on electricity costs.
An electric heater ( the only known 100% efficient device ).
Gas heaters are much more efficient. Electric resistance heaters are, by nature, hideously inefficient.
