6 Best Electric Wall Heaters (2024 Reviews)

Wall heaters are more useful than ever. Brutally cold winters and chilly nights throughout the year call for an efficient heat source. There are dozens of worthy wall heaters, but only a handful of them make the top of the list—from quick heating to energy-efficiency, we’ve covered every aspect.

The best electric wall heater is the Cadet Com-Pak Electric Wall Heater. It uses 1000 watts to quickly and efficiently heat 200 sq. ft. (18.6 sq. m.), and it blows warm, clean air throughout the building as it circulates. Install the heater in less than an hour and use one knob to control everything.

Throughout this article, you’ll also learn the following details about finding the best electric wall heater:

  • Details about the top six electric wall heaters on the market
  • What you should look for before you buy a new model for your home
  • Comparative tables, pros, and cons

What to Look for When Buying an Electric Wall Heater

Finding a high-quality electric wall heater can be challenging since there are so many options. If you’ve gone to the hardware store, you know the competition is everywhere. Fortunately, I’ve gathered three must-have qualities you should keep an eye out for.

Here’s what you should focus on when looking for a new electric wall heater:

  • Wattage and BTUs are crucial to determine the heat output and energy usage.
  • Make sure your electric heater is quiet.
  • The initial cost pairs with potential maintenance costs.

These three factors will make or break the deal. You don’t want to end up with a noisy, expensive, low-heat unit; it’ll be a huge waste of money. The good news is that all of the models on the list check every box. If you want to dive into the details about these essential components, read on below.


Energy usage is often the most important factor for many buyers. If you’re a homeowner who’s tired of spending hundreds of dollars on an old school wall heater, you’ll love the savings gained with a new-age electric model. However, they’re not all as efficient as they should be (despite recent upgrades).

BTUs and watts work hand-in-hand to determine energy consumption (aka how much you’ll have to spend to run the heater) and heat output (the amount of heat that your home will use). Thermal efficiency impacts heat’s quickness and ability to regulate itself, so find this key detail on a wall heater if you can find it.

Let’s break down a table of your home’s most used electrical items and how many watts they use here:

Household ApplianceWattage (Average)Cost per Hour (US Average)
Wall Heater (Electric)1,500$0.20
Tankless Water Heater18,000$2.41

Sources: Unbound Solar & Electric Choice

Keep in mind that some appliances, such as wall heaters and dishwashers, are only used for a couple of hours per day. While 20 cents per hour might seem high, it’s not too bad since you’ll only use it for a short time. There are many energy-efficient models that use significantly less energy on the list, too.

Heaters have a bad reputation for costing a lot of money. We’ll dive more into the cost later, but remember that it’s right about the same price as air conditioning. In some cases, wall heaters are much cheaper since you’re not using a whole-house heater. Those can cost up to $1.00 per hour.

BTUs are determined by the wattage, but you’ll need to know your room’s square footage to figure out your needs. Every watt equals 3.41 BTUs. I recommend using to find out which heater will work best for your home.

Noise Level

Noise output can be a burden caused by old wall heaters. The creaking walls, blasting fan sounds like a jet engine, and loud coils make it worse than suffering through cold weather. What’s the point of staying warm if you can’t even hold a conversation without listening to a loud wall heater?

These days, most brands focus on quiet coils, efficient heating, and other devices that reduce the overall noise output. Luckily, you don’t have to deal with absurdly loud heaters anymore. However, some of them are much quieter than others. If you want an ultra-quiet wall heater, you’ll enjoy the KING heater below.

The cage-like fan system often causes loud noise. It pulls cold air inside, heats it through the coils, and pushes it out. The whole time, the fans rattle and rumble, causing loud thumps and a roaring ambient noise.

So, how can you further reduce the sound output of a wall heater?

  • Use soundproofing materials around the heater’s edges. Heavy-duty insulation and padding work wonders. Sometimes, all you need to do is drill the screws further into the wall. A loose screw rattles around with the fan.
  • Have the heater cleaned and inspected annually. Right before it’s time to run it for the season, hire an inspector (or DIY the job) to check out your heater. You’d be surprised by how much noise you can remove by cleaning the fans, ducts, and other components.
  • Always go electric! You’re in the right place to find the best heater since electric models are almost always quieter than their gas-powered counterparts. Gas heaters burn flames, which are typically louder than low-buzzing electricity.

As you can see, your heater comes ready to stay quiet until it gets dirty. As long as you follow the manufacturer’s recommended installation instructions, you’ll be happy with the low-noise results.

Total Cost (Maintenance Included)

It’s time to cover one of the most important parts of the process. Having a quiet electric wall heater is excellent, but it’s crucial that you can afford it. Before you buy the first heater you find, please review the following influential factors:

  • The initial purchase price typically ranges between $100 to $700. Needless to say, you get what you pay for. Don’t knock a low-budget electric wall heater, though. If you need to heat a small room, they’re often more than enough to get the job done. For those who want more gadgets and customizations, you might have to spend more.
  • Maintenance costs include ductwork, padding, fan cleaning, screw replacements, and other minor repairs. Most services cost under $50, and it’s rare to have to do anything more than a cleaning session for the first several years. If you can do it yourself, you’ll save plenty of money.
  • Don’t forget the price of running the wall heater. You read above that it can cost about 20 cents per hour. If you’re running it for two to three hours per day, that’s still less than $30 per month. Some models are even more efficient, costing less than $20 per month. Your room’s square footage and the unit’s wattage will impact the energy bill.

Cleaning your electric wall heater will save money by reducing the chances of overheating, clogging, and rusting. Turn off the power breakers, unscrew the cover, wipe down the blades and ducts, then replace everything. This simple method will save your heater from early repairs and loud fans.

Best User-Friendly Design: KING W2415-W W Series Wall Heater

The KING W2415-W W Series Wall Heater uses many features of the previous KING wall heater. It cuts back on noise, energy usage, and many other unwanted side effects of heating a room. Fortunately, this version is even smaller than its predecessor. What makes it slightly better for some people is that it’s quite user-friendly.

KING W2415-W W Series Wall Heater, 1500W / 240V, White

A small knob can adjust the thermostat for instant results. Why wait around for slow fans or dragging temperature increases if you don’t have to? Although it’s simple, this heater is far from ineffective. In fact, many users claim it’s much better than a high-end heater that costs twice as much.
