There are numerous types of electric heaters (also called “radiateur” in French) with different functions and efficiency ratings out there in the market. Electric heater is an appliance using an electrical resistor to convert electric current into heat.
It is wise to do some personal research in order to avoid any deception. Some people might tell you that electric portable heaters are really efficient. Others will say that heat pump electric heaters are the best. There are some sources that will say that heat pump electric heaters are the best. There are also some sources who will say that for you to determine their efficiency, simply reduce it to basic economics. You can also calculate the efficiency of the electric heater. For that, simply multiply the cost per kilowatt hour by the number of kilowatts the heater uses and the efficiency rating of the heater.
Electric heaters are classified as conductive, radiative and convective. Based on different types in the market, you should be aware that understanding how these technically run can play an important role to determine the efficiency of this type of heater.
You can have a central electrical heating system or a movable space heater which can either be portable, radiative or convective. You can also opt for baseboard heater which operates from a mix of convection and conduction. Also there is the underground heat pump technology which numerous people think is the most efficient.
