When choosing an electric heater for a small space, consider factors like energy efficiency, safety features, noise level, and the specific heating needs of the space.

Electric heaters are generally considered to be 100% energy-efficient in terms of converting electricity into heat, as nearly all the electrical energy is transformed into thermal energy. However, this does not necessarily make them the most cost-effective or environmentally friendly option compared to other heating systems. Gas furnaces, for example, can have efficiency ratings ranging from 78% to 98%, depending on the model and age. While they may not convert energy as efficiently as electric heaters, natural gas is often cheaper than electricity, making gas furnaces more cost-effective in many regions. Heat pumps, which can be air-source or ground-source (geothermal), are more energy-efficient than electric heaters. They transfer heat rather than generate it, achieving efficiencies of 200% to 300% or more. This means they can produce two to three times more heat energy than the electrical energy they consume. Oil furnaces are less efficient, with ratings typically between 70% and 90%. They are often more expensive to operate due to fluctuating oil prices and are less environmentally friendly due to higher carbon emissions. Wood-burning stoves and pellet stoves can be efficient in terms of fuel use, but they require manual operation and regular maintenance.
