Best Electric Wall Heater Reviews (Top 10 List)

1. Stiebel Eltron 236305 Electric Wall Heater

Stiebel Eltron 236305 Electric Wall Heater

If you’re looking for overall best electric wall heater, then this is it.

With a super-quiet noise level of just 48dB(a) and measuring only 5.13 x 10.88 x 15.75 inches, the Stiebel Eltron 236305 Electric Wall Heater is the perfect choice for warming up rooms sized 175-200 square feet. 

This wall heater features a clever down-draft design that pulls in cool air from the top and pushes warm air out of the bottom. This allows for a more efficient and even distribution of heat throughout the room.

It also features a built-in thermostat with a temperature range of 41º- 86ºF. Or you can go one step further and hardwire the heater directly to an existing wall thermostat if you want that type of control.

You can provide an extra boost of heat on those particularly cold days too by turning the booster-timer function on. This makes the heater operate at maximum heat for 60 minutes and, when the time is up, automatically switches it back to your chosen thermostat temperature. 

There’s even a frost protection setting that will maintain temperatures at just above freezing. 

This is ideal for keeping your room temperature just warm enough when you’re not at home, meaning that you’ll never have to come back to a cold room but not wasting any heat or energy during the process.

The simple on/off switch makes operating this wall heater easier than ever. 

And, with its 1500W power output, it’s a great option for anybody on a budget, generally costing between $0.15 – $0.30 per hour to run depending on your local utility rate.

2. Broan Nu-tone Wall Heater

Broan Nu-tone Wall Heater

Different room sizes throughout a house take different amounts of time to warm up, and the cost of heating smaller and larger rooms can vary dramatically. 

This is why, when you’re shopping for an electric wall heater, it’s not a “one size fits all” deal. 

Luckily, Broan Nu-tone has thought about this and has designed a fantastic wall heater that is available in three versions: 1000/2000W, 500/1000W, 750/1500W. 

And each of these electric wall heaters features dual power-output levels too.

This allows them to automatically convert to half their power output depending on whether your electrical system is wired at 120V AC or 240V AC.

But what’s the difference between the three wall heaters, and why would you choose one over the other? 

Well, it all comes down to the size of the area it can warm up and how much it costs to run. 

Let’s take a look at these details in a little more depth for each of the three heaters:

  • Nu-tone 170
    • 500/1000W (120V AC / 240V AC)
    • Average running cost of $0.06 – $0.12 per hour.
    • Has a coverage area of 65-100 square feet. 
  • Nu-tone 174 
    • 750W/1500W (120V AC / 240V AC)
    • Average running cost of $0.09 – $0.18 per hour.
    • Has a coverage area of 100-150 square feet.
  • Nu-tone 178
    • 1000W/2000W (120V AC / 240V AC)
    • Average running cost of $0.12 – $0.24 per hour.
    • Has a coverage area of 135-200 square feet.

As you can see, being able to choose between three versions of this heater gives you the versatility you need to provide warmth throughout your home without wasting any energy or money. 

This is what makes it one of the best wall heaters available.

They also feature a clever downward-louver design that directs heat towards the floor, allowing it to rise throughout the room. This means the air throughout the entire room warms up more evenly.

There’s also a conveniently placed thermostat on the front of each of the three versions. This allows you to select the perfect temperature for your needs and maintain it at that level. 

It has an automatic shut-off function too, and this helps to save you money and conserve energy by powering the heater off once the desired temperature has been reached. 

This wall heater is quick and easy to install as well and can either be surface mounted or recess mounted depending on the features of your room. 

It’s also highly dependable and features a permanently lubricated motor, high-efficiency blower wheel, and a super-durable nickel-chrome heating element. 

And, as if that wasn’t enough, the entire case features a baked enamel finish that adds external durability.

This wall heater’s performance is further enhanced by its aluminum fan, permanently lubricated motor, and Ni-Chrome coil element that provides instant heat.

One of the standout features of this wall mounted electric heater, however, is the patented Smart Limit Technology. This senses potential hazards such as clogging in the element, an issue with the power supply, or an object blocking the heater, and automatically shuts it off.

This is a fantastic way of keeping you and your family safe while the heater is in operation.

You can also pair it with a line-voltage thermostat of your choice: mechanical, touchscreen, or Wi-Fi control.

Here’s a breakdown of each of them in terms of wattage, running cost, and area coverage:

Another feature that separates this heater from the W Series is the inclusion of a whisper-quiet squirrel cage blower. This means that you’ll be able to keep it running without having to worry about it making too much noise, and this is particularly ideal if you’d like to install it in your bedroom and leave it on overnight.

This makes it ideal for anybody looking to reduce their household bills as well as their carbon footprint. 

Like a lot of wall heaters, it is available in different wattages to suit your heating and electrical needs. 

However, the energy efficiency performance allows each model to provide the same power as a traditional wall heater while consuming less electricity:

The plug-in thermostat gives you full control over temperature selection between 41-86ºF, and this heater also features overheat protection as an added safety measure. This automatically shuts the power off when the desired temperature has been reached.  

It doesn’t use a fan to generate heat either, so it’s ideal for anybody that suffers from asthma or dust irritation.

Instead, it ignites with minimal radiant heat that transmits to convection currents. These currents then rise from the back of the heater and circulate throughout the room for increased efficiency. 

The 400W version also features Wi-Fi connectivity, allowing you to power the heater on and off as well as adjust the thermostat from your smartphone. This is really useful if you’re heading home on a cold day and want to pre-warm your room ready for your arrival.

Both the 400W and 600W versions are available to purchase with or without a heat guard as well, and this has a couple of uses. 

Firstly, it doubles the efficiency of the convection currents, helping warm air circulate more effectively throughout the room. 

Secondly, it acts as a protective shield over the entire heater and prevents anybody from touching it while it’s hot, without gaining a high temperature itself. 

That makes it an ideal choice for a household with children or pets.

Electric Wall Heater Buying Guide

What is a Wall Heater?

A wall heater is a fantastic alternative to traditional central heating and, in some cases, can even be used to provide an extra boost of heat to particularly large rooms. 

As their name suggests, wall heaters are installed on a wall by using a bracket. 

Depending on the model you choose, you’re often given the choice between putting a wall heater directly onto a wall or installing it into a recess.

Their compact size and energy-efficient performance make them a great choice for studio apartments or offices in addition to the home as they can quickly warm up a small space without taking up a lot of space.

How Does an Electric Wall Heater Work?

The way an electric wall heater works depends on whether it is a convection heater or a forced fan heater, as each one uses a different method of generating heat. 

Forced fan heaters work in a fairly simplistic way. Cool air is drawn into the heater, it then comes into contact with a heating element before being pushed back out of the heater as hot air with an electric fan.

By operating this way, an electric wall heater can warm an entire room up in a very short space of time.

Convection heaters work a little differently. The principle of cool air in/hot air out still applies. However, as the air is drawn in and comes into contact with the heating element, the molecules within the air expand, and as this happens, cooler air is displaced by warmer air. 

By operating this way, all of the air within the room stays at a consistent temperature for longer rather than rapidly cooling once it’s been pushed back out of the heater. 

One thing both forced fan and convection heaters all have in common, though, is that they are powered by electricity. This is usually provided through a cabled connection to a power outlet; however, some units can also be hardwired into your home’s wiring.

If you want to learn about all different types of heaters, we have a post on that topic as well. But for the purposes of choosing an electric wall heater, the above information is all you need to know.

Benefits of Electric Wall Heaters

There are many benefits to investing in an electric wall heater, including a couple that you might not necessarily have thought about.

Market research indicates that “the global electric wall heater market in terms of value is estimated to register 5.66% CAGR [compound annual growth] during the forecast period [up to 2025].”

Let’s take a look at some of the benefits of electric wall heaters below which are the leading reasons for why these units are become more popular. 

Space Saving

One of the biggest reasons that they are so useful, especially in smaller homes, is that they don’t take up very much space. By being installed on a wall, they leave much-needed floor space available, but still provide the room with the warmth you need. That’s what makes these units some of the best space heaters for bedrooms because they don’t get in the way.

Energy Efficient

They are also a lot more energy efficient than traditional heating. This is because they warm the air in the room up much quicker by pulling it towards the heating element, rather than relying on natural airflow to come towards the heat source. 

Some people even use these heaters in garages to keep that area warm. If you have this concern, then visit our best heater for garage guide to compare the top models for this purpose.

Thermostat Control

You’ve also got a lot more control over the level of warmth an electric wall heater generates. This is because the majority of them have a built-in thermostat which, when paired with different fan speeds, allows you to personalize the temperature a lot more than central heating. 

This is especially useful if you’d like to keep one room warmer than another in your home or if there is a particularly cold snap of weather and you’d like to give your heating that extra boost of warmth.

Easy Installation

Electric wall heaters also come with the added benefit of being quick, easy, and cheaper to install than traditional heating. This is ideal if you’re on a budget, or if you’ve recently moved into a new house that needs a lot of renovation work. These types of heaters also make some of the best bathroom heaters on the market.

Types of Wall Mounted Electric Heaters

Best wall mounted electric heater

Electric wall heaters are available as either standard wall heaters or baseboard heaters. 

But what’s the difference between them? 

Ultimately, the type of electric wall heater you go for will depend on the shape, design, and aesthetics of your room. 

Below, we’ll go into more detail on each of them.

Standard Wall Heaters

First and foremost, you have standard wall heaters. These do exactly what you imagine they do and are installed directly onto a wall; however, they can also be recessed into a cavity to save even more space.

Standard electric wall heaters are self-contained and usually have a built-in thermostat that allows you to control the temperature however you’d like.

Baseboard Wall Heaters

The next type of electric wall heater available is a baseboard heater. These use convection technology to draw cool air into the bottom and let warm airflow from the top. 

Baseboard heaters are generally a lot smaller than standard wall heaters and are usually placed underneath windows to counteract any heat loss through the glass. You can view our baseboard here reviews here.

To help make things a little clearer, take a look at this quick-reference table that indicates the differences between the two types of wall mounted electric heaters.

  Wall Heaters Baseboard Heaters
Heating Time Can heat an entire room in as little as 30 minutes depending on size Can take 30-60 minutes to heat an entire room depending on size
Wall Space  Takes up more wall space Takes up less wall space
Noise Level Operates at around the same level as a modern refrigerator Operates in near-silence
Temperature  Operates at a high-temperature level. However, some models do feature cool-touch housings as an added safety measure. Maintains a cool-touch temperature throughout operation 
Durability Generally lasts 10+ years Generally lasts 20+ years

Features to Look for in Electric Wall Heaters

When you head out on your quest for the best wall mounted electric heaters, there are a few things you need to keep in mind. 

We’ve listed some key areas to pay attention to during the shopping process, and doing this will help you find the perfect wall heater for your individual needs.

Wattage Use

The first thing you need to think about is the wattage you need your electric wall heater to operate with. 

This is important because the wattage goes hand in hand with the coverage area, energy-efficiency, and cost. And it’s the basis for answering the question, “how much electricity does a heater use?”, regardless of the type.

The best way to work this out is by calculating the size of your room. 

Generally speaking, the smaller a room is, the less wattage your electric wall heater will need. 

A heater with a high wattage in a small room will certainly make it warm up in record time, but it’s a bit of a false economy as you’ll be spending more money on something you don’t need.

The wattage of an electric wall heater also indicates how much it will cost to run. And, while electric heaters are much cheaper overall than traditional central heating, placing a low-wattage heater in a large room will cost you more as you’ll need to leave it running for longer.

To make working out your wattage requirements a little easier, take a look at our reference table below. 

Wattage Coverage in Square Feet Average Cost per Hour
1000 125-150 $0.12
1250 150-175 $0.15
1500 175-200 $0.18
2000 200-250 $0.24
2500 250-300 $0.30

Keep in mind that these are estimates and, depending on the energy-efficiency of your chosen wall heater, you may find it can cover a larger area and, ultimately, leave you paying even less than you thought. 

So make sure you read all of the information listed with the heater before purchasing for the exact room size coverage you need. You don’t want to get a large space heater than you really need.


One of the best things about electric wall heaters is that a lot of them offer you full control over the temperature settings through a built-in thermostat. This allows you to accurately bring the heat levels of your room up to a comfortable temperature. 

There are a couple of options available to you when looking at thermostat settings.

The first is a twist-dial, and this allows you to quickly adjust the temperature by selecting a certain number on the dial. This number will relate to a certain temperature range, usually in increments of 10ºF.

Or, for more precise temperature control, some wall heaters offer you button controls that allow you to increase and decrease the temperature by 1ºF at a time. This is perfect if you’d like to know exactly what temperature your room is at. 

Whichever you go for, you’ll want to make sure that your chosen wall heater offers you a good temperature range. Anywhere between 41º-99ºF is ideal to get the best energy efficient electric heater.


We all know that life can get in the way sometimes and, even though you might have the best intentions for switching your heater off, it can be easily forgotten. 

This is why it’s a good idea to look for an electric wall heater that features a timer function.

This will allow you to leave the heater on for a set amount of time, and then automatically shut it off once that time has passed. 

This is also ideal if you’d like to put the heater on when you get into bed, but don’t want to leave it on all night long.

Wi-Fi Control

In our modern age of technology, it’s always worth investing in household appliances that can be controlled with a smartphone via Wi-Fi. 

An electric wall heater that has Wi-Fi functionality will allow you to turn it on and off, adjust the temperature, and, in some cases, even set schedules that power the heater automatically through your iOS or Android smartphone.

A Wi-Fi controlled electric wall heater also gives you the ability to turn it on when you’re not at home. This is ideal if you’re headed home after a long day and want to come back to a warm, cozy room, rather than waiting for it to warm up once you’ve got back. 

Overheat Protection

As with anything that produces heat, it’s a good idea to look at what safety features your chosen wall heater provides. 

One of the best is overheat protection. 

As you may have guessed, this prevents the heater from overheating and automatically shuts it off if it becomes too hot to function safely. 

This is particularly useful if you’ve forgotten to switch the heater off before you head outdoors or go to bed, and is even more useful if your heater doesn’t have a timer function. 

How to Install a Wall Heater

One of the most appealing things about electric wall heaters is how easy they are to install. 

However, the installation must be done correctly. 

If not, the heater may not work properly or, even worse, could cause some serious damage to your property.

Before you get started, here are the tools you need:

  • Screwdriver
  • Linesman Pliers
  • Wire Stripper
  • Drill

Once you’ve got all of the above tools close to hand, you can install your wall heater safely by following these steps:

  1. Determine where you’re going to place your wall heater. It needs to be near a constant energy supply (such as a power outlet).
  2. Next, turn the power off at the breaker panel to cut all electricity to that room.
  3. Using the screwdriver, remove the power outlet’s cover plate, and then remove the outlet from the box.
  4. Run 14/2 wiring from the existing outlet to the heater. You may need to drill through wall studs to do this, depending on where you’re placing your heater.
  5. Remove the sheathing on your new wire and feed that through to the electrical box.
  6. Strip the conductors on your new wire and connect them to the available screw on the outlet.
  7. Place the electrical box back inside the wall, resecure it, replace the outlet, and resecure the cover plate. 
  8. Now, strip the other end of the new wire and splice the conductors from the power supply to the correct wires on your heater.
  9. Take the mounting brackets your heater came with and secure them to the wall.
  10. Place your heater into the brackets until you hear it click into place.
  11. Restore the power to the room and turn your heater on. 

The directions above are how to hardwire a wall heater into your home; however, some wall heaters come with a plug that can simply be plugged into an electrical outlet. 

If you buy a plug-in electric wall heater, then this makes installation a lot easier as you won’t have to worry about dealing with wiring. 

In this case, follow the installation instructions provided with the heater.

Best Wall Heater Safety Tips

Wall heaters are, first and foremost, sources of heat. Misusing the heat they generate or not treating the heater with respect could lead to some disastrous and potentially fatal consequences for you and your family.

So, to help keep your home and everybody in it safe, here are some wall heater safety tips to follow:

  • Do not place anything flammable onto your heater or within a 3 f.t. space in front of it.
  • Do not use an extension cord to power your heater unless you have no other choice. If you do have to use one, make sure you monitor it at all times.
  • If the power cord or the wall you’re heater is mounted on feels hot to the touch before you’ve switched it on, do not use it. Call an electrician.
  • Do not place your heater on an unstable surface such as a table or a chair. It’s designed to be mounted to a wall and, as such, should only be used in this way.
  • Do not place your heater near a source of water, or operate anything that requires water to function near your heater.
  • Do not use a wall heater that is designed to provide heat to a space that is larger than you need.
  • Do not allow children to use or operate the heater without supervision or permission.

Additionally, experts like Runtal Electric advise that you look for a product with certification for safety standards. “One of the best ways to know if a heating product is safe is if it has met stringent safety standards. UL certification means the product meets standards for safety. CE certification ensures a product meets the European Union standards for safety.”

Common Questions About Wall Heaters

How Efficient are Electric Wall Heaters?

Electric wall heaters are extremely efficient and can warm up a room up in record time. This is because wall heaters draw the existing cool air within your home towards them and replace it with warm air, rather than relying on the natural airflow that traditional central heating uses.

But do space heaters save energy? The efficiency of an electric wall heater can reduce your energy costs because they don’t need to operate for as long as you would with central heating. This means that they are incredibly cheap to run, costing as little as $0.06 per hour in some cases. 

Being able to get such a great performance from a short amount of time also makes them much more environmentally-friendly as well. 

Can You Leave Electric Wall Heaters On All Night?

Leaving an electric wall heater on all night is not advisable. This is because there could be a risk of fire if they aren’t properly monitored. However, this doesn’t mean you haven’t got the option to switch one on when you tuck yourself into bed. You just need to make sure it has certain features that allow you to do so.

These features include a timer that will automatically power the heater off after a set amount of time. Some are even compatible with Wi-Fi and allow you to create schedules that turn the heater on and off at certain times of the day. 

However, if your heater doesn’t have these options, you absolutely must not leave it on all night. 

Do Wall Heaters Use a Lot of Electricity?

Wall heaters are highly energy-efficient and, as such, don’t use a lot of electricity while they’re in operation. However, the amount of electricity a wall heater uses will depend on its wattage. 

For instance, a 1000W wall heater will use far less electricity than a 2000W wall heater. 

Some wall heaters have Eco modes (or Energy Saver modes) that allow you to switch between two different wattages depending on your needs. This is ideal for bringing a little boost of heat to a room when needed or giving it a good blast of warmth on a cold day.

The best way to make sure your wall heater isn’t using too much electricity is to purchase one that is designed for the size of the room you’re installing it into. 

Take a look at our reference table above for a better indication of wattage you need in comparison to the size of your room.

Are Wall Heaters Better Than Baseboard Heaters?

This depends on two main factors; the layout of your room and how quickly you need the room to heat up. 

Generally speaking, wall heaters can generate heat at a much faster rate than baseboard heaters. However, they do take up a lot more space. 

Baseboard heaters take longer to warm up but are usually much smaller in size. 

Another factor to think about is how quiet you’d like your heater to be. Wall heaters usually use the forced-fan method to generate heat, and this can be quite noisy. However, there are some models available that feature noise-reduction technology. 

Baseboard heaters are generally much quieter as they use convection technology to warm up the air in a room, and this makes them a better choice for bedrooms.

How Much Does it Cost to Run an Electric Heater Per Month?

We know that electric heaters are energy efficient and, as such, tend to be cheaper to run than traditional central heating.

But exactly how much does it cost to run an electric wall heater? 

This comes down to its wattage. 

Put simply, the higher the wattage, the more it will cost to run. 

Remember, also, that the cost will fluctuate depending on your energy company’s prices. 

But, to give you a rough estimate of the cost, here’s a useful reference table:

Wattage Average Cost per Hour
1000 $0.12
1250 $0.15
1500 $0.18
2000 $0.24
2500 $0.30

Are Wall Heaters Safe?

Wall heaters are safe to use. A wall mounted heater typically has several safety features that make it both safe and reliable to use indoors. One of the best safety features is overheat protection that turns the unit of if the internal components get too hot.

How High Should a Wall Heater Be Off the Floor?

The general guideline for how high a wall heater should be off the floor is a minimum mounting height of 8″ (203.2mm) above a finished floor. Having the heater this high off the floor will allow proper airflow for effective heating.
