To kickstart our convection wall heater reviews, we have this popular King model.

Also, the powerful whisper-quiet fan keeps the heat levels up while keeping the noise levels down.

However, you’ll need to order the thermostat separately, which is mind-boggling to some customers.


  • Easy to install with quick set alignment tabs.

On top of this, it features a built-in thermostat to improve its efficiency and accuracy.

Electric Wall Heaters Buyers’ Guide

Here are some handy pointers to consider before you invest in your brand new wall heater.

Electricity Usage

Electric wall heaters are far more economical than a central heating system. 

This is because centralized systems work on the division of a heater network around your home. You don’t usually have the option of controlling individual heating vents in this system, and more often than not, you’re left running the entire heating system simultaneously.

This works well in locations where a central heating system is a must, where winter is quite harsh and consistent.

Electric wall heaters are invaluable in less harsh conditions, though.

They allow you to heat various rooms based on your requirement and the season. You can also use a thermostat to achieve the ideal temperature and avoid overheating any given space.

Not only is this method far more energy efficient in the long-run, but you also save on running costs.

The only factor you need to consider here is to find the right heater size for a given room, and you’re pretty much golden after that.

Purchase and Installation Costs

As electric wall heaters are popular, you should find a model based on your budget. Expect starter heaters for small spaces for as low as dozens of dollars. You can certainly find a quality one for most spaces for a few hundred dollars.

Heater costs tend to change based on:

  • Brand.
  • Quality of parts used.
  • Heater power.
  • The space it can effectively heat. 

Apart from that, installing these devices can be relatively easy. While central heating units are near-impossible to install on your own, you can easily do so with your wall heater. 

Most of the time, it only involves using a mounting bracket to suspend the heater. You’ll likely find the required tools to do this at home.

Running Costs

A heater’s running cost mainly depends on:

  • Heating element’s efficiency.
  • Power.
  • Heating method.

Make sure to look out for units with an integrated fan. These units tend to heat your room far quicker compared to their counterparts. You should have a nice and toasty space in a couple of minutes.

Such models tend to be a bit more expensive, but they’ll certainly help you cut costs in the long run. 

When it comes to power, the greater this is, the more expensive the model is to run. But, it’ll also heat your space a lot quicker. With this, strike a balance between power output and your space at home.

There’s no need to buy the most powerful model to heat a small area. Conversely, it won’t be powerful and efficient, and you’ll run it constantly.

If you’re considering a model that relies on convection currents for heating, these models take a lot more time to heat a given space. Their heating consistency is excellent, and the room will stay warmer for longer, but the initial heating period can take a while.
