1. Usage and Cost

Let’s face it; the electric heater has somewhat of a bad reputation.

This is because most electric heaters usually consume lots of electricity that is expensive to run both in the short term as well in the long term.

Therefore, when looking to purchase an electric wall heater online, take a look at the usage as it will dictate its cost.

For example, if you are planning to use your electric wall heater to heat a big room, then you need a model that not only consumes a lot of power but expects to pay more in terms of electricity.

However, if you only need to heat a small to medium-size room, then the electric wall heater may be more economical for you.

2. Power

The power of the electric wall heater is usually measured in watts of power. This value basically shows you how effective the electric wall heater is in heating a room.

Obviously, the higher the wattage of the wall heater then the more performing it will be. Some of the best electric wall heaters on the market have a power rating of 2,000 W or more.

Even if this is highly demanding in terms of electrical costs, the main advantage of it is that it will have no problem heating up a room fast.

However, most electric wall heaters are quite versatile and come in a wide range of powers depending on your need.

In fact, many models provide you with the possibility of switching the electric wall heater to a lower power consumption if you need to.

All you have to do is flip a switch inside the heater during installation, and you’re good to go.

You may want to check if your electric wall heater of choice has this dual power functionality because not all of them do.

3. Design and Appearance

Since the electric wall heater is usually installed in a place that is clearly visible to anyone, it is somewhat important that you go with a model that is aesthetically pleasing.

You can even do a paint job on this heater to make it match your room décor and color if you need to.

In addition, the design is also quite important because it will dictate how efficient the electric wall heater is.

Go with a model that has grills that protect the inside of the heater from touch.

Additionally, it should have vents that are angled in such a way to allow more efficient circulation of hot air into the room.

4. Safety Features

We cannot talk about an electric wall heater without mentioning its safety features.

What this function does is automatically switch off the electric wall heater whenever it senses that it is heating too much.

Since this device outputs a lot of heat really fast, it must be equipped with safety features like overvoltage and overheating protection.

This will prevent the risk of a potential fire from happening.

5. Control Settings

Versatility is important in an electric wall heater. In order to get this versatility, you need to be able to control the heat output (temperature) of the heater.

You can do so by using a thermostat. Many top-rated electric wall heaters actually come with an inbuilt thermostat that provides you with full control over the temperature regulation.
