Most Energy Efficient Electric Wall Heaters Comparison

How Do Electric Wall Heaters Work?

How do energy efficient electric wall heaters work?The basic principle of electric heaters is that they convert electric energy into heat energy. The heat energy is then used to warm the air in spaces. However, the actual mode of operation of electric wall heaters is more complicated than this simple description.

Electric wall heaters have heating elements that are usually made of ceramic. The heating elements convert electric energy into heat energy. The elements may be used to heat a liquid or produce ultraviolet radiation. Heaters that operate in the form of a heating element passing heat energy into a fluid are referred to as convection heaters.

The fluid, which acts as a heat sink, slowly passes the heat energy to the air currents that come into contact with the heater. The electric heater has to continually take in cold air currents and release heated ones. To expedite this process, such heaters may have an inbuilt fan.

Radiant heaters have reflectors that direct the ultraviolet radiation that is produced to animate and inanimate objects in the room. Such heaters tend to provide warmth very fast and reliably.

Benefits of Energy Efficient Electric Wall Heaters

Value for Money

It is more economical to invest in electric wall heaters than other systems and devices like fans. After installation, electric wall heaters do not require a lot of attention. You do not have to disassemble your heater to clean its internal components regularly. This is unlike many other alternative sources of energy.

Although the purchase costs may be significant, you will not spend much on repairing, maintaining, or even replacing your electric wall heater. In the end, an electric wall heater delivers more value for money than other types of electric heaters such as stand-alone fireplaces.

Continuous and Comfortable Heating

Electric wall heaters are designed to provide secondary heating in homes and even offices. When placed in strategic positions, they reliably and continuously warm the space to create and maintain a cozy environment. Therefore, they are best used for zonal heating in homes to complement the central heating system.

Most energy efficient space heaters have advanced control features, including remote control and settings for changing their temperatures and timing of the operation. You can use such settings to personalize the performance of your electric wall heater according to the heating requirements of your home.

Efficient Use of Energy

Electric wall heaters are more energy-efficient than many other types of heaters, including energy efficient propane-burning space heaters. Although the rate of conversion of electric energy into heat energy for electric wall heaters is not exceptionally high, their design and control features enable users to control the amount of electric power used for heating.

You can use the inbuilt thermostat and timer to determine how hot the heater should be and how long it should operate respectively. By controlling these two aspects of use, you can end up minimizing the amount of electric energy that is used for heating the home.

Types of Energy Efficient Electric Heaters Wall Mounted

Radiant electric heaters have large reflectors that are used to guide infrared radiation within a room. Such heaters directly warm up animate and inanimate objects in a room to create and maintain a cozy feeling. The reflectors ensure that the radiation, which provides the warmth, is directed to the living zone. The living zone is the space between the floor and the roof.

Convection electric heaters contain special radiators that are full of fluid. The most commonly used fluid is oil. A heating element converts electric current into heat energy. The heating element then transfers its heat energy to the oil.

When the oil is fully hot, it starts to project the heat to the air that passes near the heater. Thus, such types of electric wall heaters warm the living space by heating air currents that come into contact with them.

To speed up the process of heating air currents, some convection heaters have fan systems. The fan system forces the heated air out of the heater and distributes them across the room quickly to create a comfortable environment.

Micathermic electric wall heaters combine convection and radiation heating methods to deliver great performance in small rooms that require rapid heating. The heaters may have fans to speed up the distribution of heated air in rooms. Also, the use of infrared radiation ensures that such heaters create and maintain a comfortable indoor environment fast.

Factors to Consider when Choosing Energy Efficient Wall Heaters

Getting the perfect energy-efficient electric heaters wall mounted for your home is a complex process. There are many brands with different features that are available on the market. You have to be certain about the heating requirements of your home to make the right decision. Here are a few things that you can look out for when choosing an electric wall heater.

Thermostats and Timers

It is more convenient to use wall heaters that have digital thermostats and timers than those which do not have these features. A thermostat helps you to determine the ideal temperature at which your heater should operate. The selected heating level is usually based on the ambient temperature.

Timers can be used to program the length of time during which a heater operates. For most brands that have inbuilt timers, users can program them to automatically operate for as long as eight hours. The minimum timer settings for electric wall heaters is an hour.

Although brands that have timers and inbuilt digital thermostats cost more than those which do not have these features, such brands offer greater convenience than the others.

Heating Capacity

When choosing an electric wall heater, consider the heating requirements of your home. The amount of heat that you need to keep the home warm and comfortable varies considerably. This may depend on external factors such as the season and prevailing weather conditions as well as internal factors such as the design of the house.

Houses with particularly high ceilings tend to require extra heating energy than those with conventional ceilings. This difference occurs because houses with high ceilings have a correspondingly high-temperature difference between the floor and ceiling.

Although standard electric wall heaters consume either 750w or 1,500w of power during operation, they may not be enough for warming large houses with high ceilings, particularly during winter. In such cases, choose electric wall heaters with high BTUs. We have reviewed some of the best wall heaters for large rooms.

Safety Features

Consider purchasing heaters that have advanced safety features, including cool-to-touch and automatic shut-off. Heaters that have such features offer greater value for money than those which lack.

A heater that automatically goes off when its temperature rises rapidly will rarely cause accidents or get damaged as a result of overheating. Also, an electric wall heater that has a cool-to-touch feature will not cause accidents when accidentally touched.


The design of an electric wall heater is important because the device will be visible when installed in the house. If you install your heater in the living room, then ensure that you choose one that has a design that blends with your interior décor.

Electric heaters may either be modern or traditional in design. Moreover, the finish may be sleek and modern or old-school. Your choice of an electric heater based on the design and finish largely depends on personal preferences and the décor of your home.

Wrap Up

Wall-mounted electric heaters are great options for spot heating and saving floor space. As you might have realized, they are more like electric space heaters. The difference is that they are installed on a wall.

Also, there are different types of energy-efficient electric wall heaters. You can use a fan heater, infrared heater, or micathermic heater. All of them have their pros and cons, so it’s you to decide the type of heater you prefer.

However, micathermic and infrared wall heaters can help you save electricity because of how they heat the room. On the other hand, fan heaters are more expensive to run but are also energy efficient because all energy input goes into the room.
