Buying Guide

How to pick an energy-efficient electric wall heater

Wall Heaters

There are three main things you should think about when picking an energy-efficient electric wall heater: size, position, and aesthetic.

Size and Position

The size of an energy-efficient electric wall heater will change the amount of heat that it can produce. With larger internal heating elements comes a larger amount of heat produced. So, if you have a very large room that you need to heat up, then you should buy a larger heating unit.

In addition, it’s important to note that you should try and position these heating elements away from windows. Depending on the size of the heating element you’ve bought, this might be a hard task. Be sure to buy a heating element that can fit into the room you want to put it in.


We’ve tried to include a range of aesthetic choices on this list. We’ve chosen more traditional designs and have also included modern products. The wall heater you buy should match the current design of your home.

Since they’re being bound to the wall, you’ll want to make sure you like how it looks. You don’t want to attach the wall heater and then decide it doesn’t fit your style; they’re not as easy to remove as a space heater!

Are electric wall heaters energy efficient?

Electric wall heaters contain an electrical element and a reflector positioned right behind it. As heat is generated, the reflector pushes the heat up and out of the electric wall heater. From there, the heat rises, creating a convection current of air that circulates the room. In minutes, hot air will have effectively circled the room, creating a pleasant temperature.

One of the fantastic things about electric wall heaters is that the electrical element they use is 100% efficient when it comes to heat generation. Instead of losing energy while producing bi-product kinetic or sound energy, these heaters only produce heat. This makes them incredibly energy efficient.

Similarly, the wall heater’s position means no heat is lost through other pathways. For example, if you think of a traditional fireplace, some of the heat generated would travel up the chimney and out of the house.

However, when it comes to a wall heater, the heat produced is directed into your home. There isn’t a pathway for the heat to follow that doesn’t warm up your home, making them very efficient if you’re looking for a heat source.

Do wall heaters use a lot of electricity?

One of the downsides to wall heaters over other options, like a space heater, is the relatively high cost of running them. Electricity, depending on where you are, is an expensive utility. These heaters use a lot of electricity to generate heat.

One of the best ways to cut back on the amount of electricity they use is to position them well in the room. If you place your wall heater directly under a window, then the heat will have an opportunity to escape the room. However, if you place it somewhere out of the way, where the only pathway is up and into the room, then you’ll save electricity since less heat will be lost.

Additionally, the wall heaters we’ve selected for this list are all energy efficient. They will cut back on the amount of electricity used and provide you with a fantastic heating source.
