The most energy efficient radiator heater is the oil filled one. A better option would be an electrical one because those are almost 100% energy efficient.
Woodway Treadmills claim to be the most energy efficient.
In recent years, LG appliances have been made to be energy efficient. LG claims that it's third generation refrigerator compressor is the most energy efficient in the world.
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.

"Octanol is not the most energy efficient fuel. Butanol is. Octanol gives out 8691.34J of energy per gram. Butanol gives out 15521.21J of energy per gram" Please state your source.
Any heater that has the Energy Star label will be very energy efficient. The Honeywell eco line, for instance, are very energy efficient.
The question is better defined as "What the most energy efficient portable heater?" Because one would assume that you will want to be able to take the heater with you when or if you move.
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.
Vornado is the brand of heater that is the most energy efficient. If used properly, Vornado heaters can heat just as well as a larger heater, for a much lower cost. They are small, portable, and can heat large rooms. Some of them even have thermostats or timers to increas efficiency.
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.
Woodway Treadmills claim to be the most energy efficient.
A large energy saving one. It will keep lots of hot water and will use less energy when not in use.
LEDs are the most energy-efficient lights as of 2016.
In recent years, LG appliances have been made to be energy efficient. LG claims that it's third generation refrigerator compressor is the most energy efficient in the world.
Any dishwasher that is Energy Star Rated is energy efficient.
A ceramic heater is going to be your best bet. They are small, use little energy, and actually have a much more powerful output of heat than most heaters.
