When choosing a new electric heater, its efficiency is one of the factors that you must consider before you buy one. That way, you can pick the right product that can fulfill your heating requirements. Electric heaters may all have the same goal, which is to provide warmth to your room, but they differ in the ways they are able to generate and distribute heat, and their efficiency will depend on those factors, too. With that in mind, here are some facts you must know about electric heater efficiency:
- There is no such thing as an ENERGY STAR-approved electric heater. Resistance-based elements of electric heaters are completely efficient in converting electricity to heat, so there is no point in rating them. Efficiency issues occur due to poor energy conversion. Hence, you need to take note of how an electric heater can be effective for your requirements by looking at how it works and how it generates heat and warmth.
- Heat pumps can provide more heat per output per unit of electrical energy input compared to resistance-based heaters, but that does not mean that they are completely 100 percent efficient. However, they can be three to four times more efficient compared to electric resistance heaters in terms of the amount of heat they provide from the electricity they consume. Take note of how electric heat pumps produce heat, and that is by converting electrical energy into mechanical energy, which moves heat from a cold to a warm area.
- The efficiency of the electric heater can be affected by the size of the room where it will be placed. When choosing a heater, you need to consider the coverage area of a room to make sure that it can produce enough watts. For instance, if you have a 1500-watt heater, then it can warm an area that is 150 square feet in size. Remember that power will determine the efficacy of the heater, so consider the size of the room first before purchasing an electric heater to ensure that it will be efficient enough for your application.
