What is the best wall heater? The most important characteristics of these devices include dimensions, power output, additional features, and, of course, design. Wall heaters typically take 10W to heat one square foot of the space, so if your room is about 100 sq ft, you will need a unit with an output of at least 1000W. Keep in mind that poorly insulated rooms or those with high ceilings require more heat. That is why a 1500-watt model is the best option. Also, make sure that the product has several power settings and operates quietly and won’t bother you during sleep. We believe that Stiebel Eltron 074058 Wall-Mounted Heater fits these criteria best.

What You Will Learn from This Guide:

It’s going to start getting cold soon, and in light of that, you’re going to need to be thinking about your heating system, if you’re not already well on top of that. Sure, your home is probably all set up for this, but what about places like your garage or shed or workshop? You can’t really connect your central heat up to these places.

Well, that’s not entirely accurate, you could hook your heating system up to these, but do you really want to always heat your garage or workshop? Take me for example. I live in Florida, and while it doesn’t get intensely cold here like other places in the country, it gets chilly enough that I do need to heat those places myself.

Now, the thing is, I almost never turn my heat on in the house. It really doesn’t get cold enough for the house to actually get that cold itself, especially given how well-insulated and well-sealed this house is. My workshop is quite a bit chillier than my house, mostly because it’s kind of more exposure to the elements. I don’t want to turn my heat on, but I need to pump a little bit of heat in there to cut the chill when a customer is coming to see the arcade cabinet I am building for them. It’s common courtesy to do this.

Likewise, my neighbor is a seamstress, and she works out of her garage. She heats her garage when customers come over in the winter morning or evening.

Today, I’m going to talk a little bit about wall heaters, which are a lot simpler than you might think.

So, how do wall heaters work? They’re almost entirely electrical, though the method wherein they convert the electricity can vary widely from one to the next. There are standard element heaters, ceramic heaters, UV heaters. Rarely are they ever gas or oil or anything like that.

Sometimes, they’re connected to some ductwork in the room. Sometimes they’re set into a window, sometimes they’re set into a recess cut into the wall. There are really only a few things to consider with these. BTU output does matter, voltage compatibility with your wiring is very important as well.

Also, do you want to have to modify your wall itself, or do you prefer to just use a hole that’s already there via a window? Combination units do exist which provide air conditioning and heat both. They’re rare, but if you’re looking for simplicity, you might want to look into something like this.

I don’t have a wall heater in my garage workshop for the sheer fact that my garage’s walls are all made of cinderblock, and I’m not into trying to modify cinderblock like that.

Aside from these factors, though, there’s not that much else worth worrying about, honestly, there isn’t.

So, what are the ups and downs of using one of these? Well, unlike some other heater technologies, there are some problems with them. The biggest problem is, while they’re not that complex, they’re a little bit of a pain because you have to install them. This means cutting a recess into the wall, building framing around them, assembling them, and I won’t lie, that kind of thing is well outside my own handyman capabilities.

This means that unless you’re particularly handy, you’ll have to have a contractor come in and install the thing, which will incur more expense and just overall be a bigger pain in the ass.

The convenience though is that these, if installed properly, do raise the resale value of your home, and they’re a lot more efficient and effective than space heater approaches. They’re designed to heat a larger space, and they’re better insulated. They’re a lot safer if you install them properly, and if you install them properly.

They tend to be fairly affordable and offer a bit more localized control than other heating systems, which is also nice when you only use the heat occasionally. You may want to consider all the other solutions available before committing to wall heaters because I for one do consider what you have to do in order to install them to be way bigger of a pain than it has any right to be, myself.

Now, you’re understandably asking, “what situations will I encounter where the effort of this is justified?” This is completely forgivable, considering I’ve stated my case for precisely why I don’t have one. I’m not wild about the amount of construction work and handyman stuff this involves – I am a nerd at the end of the day, so while I’m handy with tools, it’s really only when I’m building custom electronics. I’m so not a DIY person with house stuff because it’s a pain in the butt.

There are a few situations where these are ideal though. Chief among these, this is a fairly solid technology to install in individual rooms you rent out, or for apartments. It’s also good for garages, detached buildings and garages and the like as well.

This isn’t too bad of technology for emergencies, and it can actually work for heating all the rooms in a small enough house. I’ve seen this technology used for bungalows and small ranch houses often enough. The benefit is, it allows each person to adjust their own room to their desires, so if someone doesn’t like it as hot as you might, they can dial it back in their own rooms, without causing fights.

As you see, they’re a little more specific, case-wise, than other heater types we’ve looked at.

A big thing to consider here is that you never want to go with one of these if you don’t own the building, because most of them actually require some level of structural modification, and you’ll need permission from your landlord to do that, obviously.

It all comes down to whether or not the benefits they do offer is worth the additional cost of having them installed, and whether or not the walls are going to cooperate with you. If your walls are made of brick or cinderblock, this will be an unholy pain.

If you’re going to do this, it’s going to be for a small professional space, a space you rent out, or something else where you’re not that into space heaters (which are admittedly shabby for such purposes). Just, take time to really be sure that this is going to work with your space, that you have the funds to have it installed (I’m going to say don’t DIY this unless you’ve actually done something like it professionally), and that the benefits really are enough for you to go through with the hassle of putting these in place.

Now, we’re going to look at two of these we’re comfortable with recommending.

TOP Best Wall Heaters

Below, you will find the TOP-2 best wall-mounted heaters at a price ranging from $80 to $150. Both models come with the analog dial control but they differ in the way of installation. The first model is easier to mount while the second one requires construction work and advanced assembly.

If you don’t work with HVAC stuff yourself, you probably haven’t heard of Stiebel, and that’s fair enough. Stiebel makes hand dryers, ventilation systems and commercial wall heaters like this one. You will notice that this one installs pretty simply, just mounting on the wall with a power supply run to it.

This is about as simple as these can be, and actually does install without modifying the wall particularly much. It’s still not going to mount easily to brick nor cinderblock, but it’s not impossible.

If I was going to have a wall heater, this is probably the right one for me, to be honest with you. The other one on our list involves far more hassle, and you’ll hear about that shortly.

Features

  • Power – Standard.
  • Control – Analog dial.
  • Requires construction work – No.
  • Requires advanced assembly – No.

Performance

Really, as far as performance, a wall heater is a wall heater, unless it’s a big, industrial implementation. You see these a lot in things like gas station bathrooms and the like, so if you found those to work well, then you can count on this.

Pros Cons
  • Easy to install.
  • Reliable brand (if not known in the consumer sector).
  • Effective.
  • Controls are overly-simplified. Ever heard of digital readouts, Stiebel?
  • It looks like it belongs in a public restroom (which is a common place these are found).

Broan Wall Heater with Built-In Adjustable Thermostat

Broan is a bit more well-known. The advantage to this one is that it can be installed into the wall (a recess kit is available for a separate purpose, which is easy to use), or surface-mounted.

I was going to discuss how this installation works, but without ordering the kit (and I’m not doing that because I can’t install one of these in my cinderblock walls), I can’t get instructions on this.

Features

  • Power – Standard.
  • Control – Analog dial and digital readout.
  • Requires construction work – Sometimes.
  • Requires advanced assembly – Yes.

Performance

I like that this doesn’t require modification to walls if you don’t mind it sticking out. However, a recess kit is available to put it in walls, and by all accounts, it’s not difficult to do. Unfortunately, as I said, further information on this is remarkably hard to obtain.

Pros Cons
  • Reliable brand.
  • Two methods for installation.
  • Digital readout.
  • I don’t like dials.
  • I can’t get examples of the recess installation, so I can’t vouch for how hard it is to do.
