Best Electric Wall Heater Buyers’ Guide

How Does Electric Wall Heaters Function

Electric wall heaters generate heat via 3 main methods. They are convection, radiation and combination.

Convection heating works by heating up the air around it via a heating element. The hot air rises and creates a vacuum for cool air to be sucked in and warmed by the heating element. This continued flow creates a circulation of warm air that helps to heat up the room. As such, convection heaters work best in closed spaces. It may sometimes come with a fan to push the air over the heating element to provide faster heating.

In radiant wall heaters, the heating element gets heated up and transfers the heat outwards around the room. It is able to heat up a small room very effectively. It is also very quiet as there are no fans involved 

For combination heating, it is actually referring to the micathermic wall heaters. They contain similar heating elements to convection heaters but the difference is that it is covered in mica which is a type of stone that generates and holds heat very well. The mica stone gets heated up and emits electromagnetic rays arounds the rooms and heats up the furniture in the room. The heated furniture then heats up the air in the room. Micathermic heating gives the most even and widespread warmth.

 2 Important Points To Note About Electric Wall Heaters 

Heater Positioning

In essence, electric wall heaters are space heaters. However, instead of it being portable, wall heaters are fixed on the wall. It may either be mounted on the surface or in a recessed part of the wall. Therefore, it is a permanent fixture once installed hence you do need to be quite certain where you intend to place it. We will be going through later in our guide on the best position to position your wall heater so do keep reading! 


Another key aspect to note about electric wall heaters is that they are hard wired. However, there is no cause for worry as almost all reputable wall heaters come with an installation kit that are easy to understand and use. If you prefer a more visual explanation, some brands of electric wall heaters also have YouTube videos going through the steps of installations. And finally, if you are really not comfortable installing it yourself, just ring up your electrician and get ready to enjoy your toasty room. 

3 Tips On Where To Install Your Wall Heater

Under A Window

The best place for a wall mounted heater is under a window. Cold air will enter through the window and sink right down to your heater. The heater will then suck in the cold air and heat it up with it’s heating element and circulate the warm air into the room. 

Away From Furniture

It is best to get a spot where there is no obstruction in front of your wall heater. The main culprits are usually bulky furniture that blocks the circulation of heat. In this sense, it might be worthwhile to invest in a heater that looks presentable as it will be out in the open greeting your guests.

On A Different Wall From Your Thermostat

If the heater is placed too near to your thermostat, the thermostat will always register a higher temperature of the room than what it really is as it is registering the temperature of the air closest to the heater. This might screw up your central heating system and let it think that the house is warmer than it really is.

In both articles, we interviewed industry expert to ask them for the best advice and also to debunk certain myths about these devices.

5 Considerations Before Buying Your Electric Wall Heater

Intent Of Use

Your electric wall heater is not meant to be the main source of heating in your house. That role belongs to your central heating system. Your wall heater will be an excellent source of heat in a small to medium sized room or as a supplementary source of heating in a large living room. However, if you run it as a main heating source in your house, you will be sorely disappointed with the heat you get and also be horrified at your heating bill by the end of the month.

Noise consideration

As mentioned earlier, the electric wall heater could be a great addition to individual rooms. In the bedroom or study room, It might be wiser to consider a heater without any fans as the fans could be noisy while it runs at night. In these cases, a radiant or micathermic heater might be the better choice. Conversely, in the living room where some noise is acceptable then a heater with a fan might be preferable as it can heat up the whole room more evenly via convection.


The power or wattage of the heater will determine how big an area it can heat up. Generally speaking, in a small to medium sized room like our kitchen or bathroom, a 1000 – 1500 Watt heater will be sufficient. In a large room, you may want to then consider a heater with about 1500 – 2000 Watt of power. That being said, this is just a rough estimate. The weather conditions and the house insulation will affect the degree of heating achieved as well.

Safety features like overheating protection, tip-over protection and cool touch exteriors are some common safety features that most heaters should have. Some other heaters may have unique safety features like an auto shut-off when there is an object obstructing it’s flow. Besides the safety features of the heater, please also take note of your safety during the installation process. Although it is quite straightforward generally, we would advise you to get an electrician if you do not feel confident. Better safe than sorry!


Some heaters come with an inbuilt thermostat and some heaters don’t. For those that don’t, you will have to get it separately and then install it nearby. Naturally, it is more convenient to get a heater with an inbuilt thermostat so we highly recommend that you watch out for this feature when purchasing.
