Best Quiet Space Heaters (Safe, Energy Efficient & Silent Heaters)

Back when I was living in a dorm, I’d always be surprised when winter rolled around, and I found myself freezing despite keeping the doors and windows shut. That’s why I’ve always liked to be on top of the latest news about space heaters. Once I realized just how many models make whirring or buzzing noises, I focused my interest only on the best quiet space heaters. So today, we’re going to talk about safe and energy efficient heaters that are also as close to silent as possible.

Of course, it would help if the room you want to heat is weatherproofed. Fortunately, a little weatherstripping tape and some draft stoppers go a long way to take the bite out of the chill. In fact, some of the same methods I’ve recommended for soundproofing doors and windows would effectively weatherproof as well. After all, they’re all meant to prevent the air from passing through the cracks around the windows and doors.

Best quiet space heaters (Safe & silent heaters).

But I imagine some of you may not be convinced. So let’s talk about some reasons why you might need to get a quiet space heater. We’ll also discuss whether space heaters are a good investment at all, considering the fact that most of us already have a primary heating system. Finally, before I get into my reviews, I’ll also tell you about some of the features you’ll want to look for when shopping for your very own quiet space heater.

Why You Need a Quiet Space Heater

If you’re someone who’s particularly sensitive to the cold, you can always stock up on blankets. However, if you don’t want to have blankets trailing behind you in your own home, getting a space heater is a great decision.

There are many different models out there that are great for heating rooms of various sizes. Some of them are big and bulky, while others are small and fairly portable. In fact, plenty of them would be appropriate for RV camping, as long as you bring a quiet portable generator with you.

Additionally, you might get a quiet space heater for your office as well. It wouldn’t even be a distraction for your coworkers since it would run silently.

Even if you don’t feel that chill as keenly as other people, keeping a space heater is your home is a good idea. That way, you’d get to live in your icy kingdom, but you could still break out a heater to quickly and effectively warm your home when you have guests over.

So Are Space Heaters a Good Investment?

As for whether space heaters are a good investment, I do have one suggestion. Since many of them can effectively warm any space on their own, I recommend shutting off your home’s primary heating system while your heater is working. Still, if you want to make sure that your heater lasts for years to come, you can follow some simple safety rules:

  • Never plug your heater into an extension cord. This is mostly a precaution, but some models have been known to overheat the cord, which can be a fire hazard. Instead, most manufacturers recommend plugging their heaters directly into a wall outlet.
  • You should keep about 3 feet of space around your unit. It’s never a good idea to put things over a space heater or its cord. So make sure that your heater isn’t too close to any curtains or furniture.
  • Ideally, you should also never leave your heater unattended. However, as someone who has broken this rule on numerous occasions, I’m probably not one to talk. Still, especially if you have children or pets, you’ll want to entirely unplug the heating unit if you’re leaving the room. In fact, if it’s hot from use, don’t let your kid near it.
  • Regular inspections are the one thing that will ensure the longevity of your space heater. Examine your unit closely every time you take it out of storage at the beginning of winter and before you set it away when the sun returns. Make sure that the cord is intact. If you notice strange nicks or wires sticking out, bring the unit to a professional.

As long as you stick to these safety rules, your space heater should last you a long while.

Features to Look for When Shopping for Quiet Space Heaters

If you’ve decided that you could benefit from having a space heater, you should start by learning more about them. So let’s learn more about the technology that powers space heaters, the types of units that exist and other pertinent facts about these devices.

Level of Noise

As always, one of the primary concerns I had while looking for quiet space heaters for my reviews was finding the products that can operate silently. Fortunately, many of the newer models do. The type of noise you can expect to hear from some of them is a quiet whirring of the fan.

Although not all fan heaters make noise, the ones that have moving parts are usually louder than those that don’t. Still, even electric heaters can start making buzzing noises over time. Overall, though, none of the products on my list make more than 40 decibels of noise. These are all things to consider.

Heating Technology

The technology that’s used to warm the area around a heater is possibly even more important than the type of heater it is. There are 3 main types of heating technology:

  • Convection heaters are the most common types. They work by circulating convection currents through a heating element such as electric coils, wires, or oil. Essentially, they warm the air itself, then use fans to push it around the whole room. So this heating technology is the best at heating large enclosed spaces.
  • Radiant heating, on the other hand, provides a more focused heat source. This heating technology actually powers infrared heaters, which are great for offices or bedrooms. They actually heat the objects around them, rather than the air. People usually use them under their desks or in small bedrooms for low, soft heat.
  • Micathermic heating technology is essentially a mix of the previous two. These devices can provide you with localized warmth as well as circulate warm air. However, they don’t usually use fans to get the effect, so they’re absolutely silent and very efficient.

Various types of heaters use these technologies, so here’s how you can recognize them when you’re shopping.

Types of Heaters

These are several types of heaters you’ll probably recognize. But do you know what each of them is called? I definitely didn’t know before I started digging into the matter. Basically, you’ve got:

  • Ceramic heaters, which use their positive temperature coefficient, or PTC, to regulate the temperature safely and reliably. Essentially, the electricity warms the ceramic plate inside the unit, which radiates heat.
  • Infrared or halogen heaters are some of the cheapest products on the market. These models use glowing hot tubes to heat the objects around them, so they’re not ideal for tight spaces or people with pets or children.
  • Oil-filled heaters are also exceedingly affordable. They actually use micathermic heating technology. So they’re great as both centralized heat sources and convection heaters. You’d probably be able to recognize these heaters if you saw them — they look like metal radiators.

Although oil radiators are usually fairly uniform in size, most of these types of heaters come in all shapes and sizes. Some of them are almost a yard tall, while others are barely over 10 inches. I’m going to mention all sorts of heaters, so you’ll get a chance to see how each of them performs.


Typically, the size of a heater is a good determiner of its heating capacity. And, as I’ve already mentioned, the type of heating technology it uses also has everything to do with how much of an impact it has. Even though fan heaters are usually louder than other models, they are also the most efficient at heating an entire room.

However, if you want to know the real capacity of the heaters you’re looking at, there’s a simple trick to getting the conclusive number. Namely, you need about 10 watts of power to warm a square foot of floor space. Therefore, if you have a 75 square foot room, you’re going to need a 750-watt unit. A 3,500-watt heater is capable of warming 350 square feet of space, and so on.

Of course, there are some exceptions to this rule. For one, if you have ceilings that are taller than 8 feet, you’ll need to get a stronger heater. As you know, hot air rises up. Similarly, I imagine that you’re going to have some issues getting your space warm if it has poor insulation. If you can’t invest in better insulation, multiply your square footage by 12 rather than 10 to get the total wattage you’ll need.

Additionally, some types of heaters have the potential to warm even bigger spaces than their wattage implies. For example, infrared heaters have a capacity that’s usually greater than their wattage would make it seem.

Features and Portability

Of course, you should also consider the features a heater has. Many of the most basic units only have a few heat levels and nothing else. However, some of the others also have timer functionality, remote control, adjustable thermostats, oscillation, and portability features like wheels or handles. What’s more, some of the heaters have energy-saving modes, and many have various safety features.


Naturally, when you’re dealing with something that’s potentially a fire hazard, you want it to have safety switches. One of the safety features that’s caused me the most grief is the tip-over protection switch.

That feature is usually a switch on the bottom of a heater that is released if the unit falls to the ground. So the heater can only work if the switch is pressed. I can’t tell you how many times I’ve thought that my heater had died when it just hadn’t been positioned correctly.

Another safety feature that has managed to surprise me in the past is the overheating protection switch. Every once in a while when my old infrared heater had been working for a long time, it would just turn off and come back to life a few minutes later. As it turns out, it was just the overheating protection feature having my back.

Other than these two safety features, many manufacturers add a unique twist to their units. For example, some heaters are moisture-resistant, so you can use them to warm your bathrooms before taking a bath. And many units are also cool to the touch, which would be the ideal choice for people with pets and small children.

Energy Efficiency

Many manufacturers boast about their products being energy-efficient, but are they really? Well, if you want to calculate the amount of energy your heater would be using every day, there’s a simple way to do it.

In fact, you can calculate exactly what your heater would be costing you on a daily and monthly level with a simple equation. Just multiply the heater’s kilowatts per hour by the average amount of time you’d be using the device per day. Then multiply that with the electricity (or utility) rate from your electricity bill, which is the cost per kilowatt hour of electricity. That’s going to be your daily estimate of how much you’re paying to run your heater.

Let’s say that your heater is a 1,500-watt unit. You can calculate the kilowatt per hour number by dividing that by a thousand. So that’s 1.5 kilowatts per hour. If your utility rate is $0.10, and you’re using the heater for about 8 hours a day, that gives us a daily operational cost estimate of about $1.2.

So when you’re getting ready to shop for the perfect quiet space heater, you should have all of these things in mind. Start with the square footage of the space and consider your needs before settling on the best quiet space heater for you.

Best Quiet Space Heaters on the Market (2021)

Now that you know all there is to know about quiet space heaters, I can get into the reviews. I’ve decided to list these products going from the largest to the smallest. Or rather, from the tallest to the shortest. Although size isn’t necessarily a factor in how big of a space a heater can handle, you’ll probably want to consider it if you need your heater to fit into a small area.

1. Lasko 5572 Ceramic Tower Space Heater

This 1,500-watt ceramic tower heater from Lasko is a tall and narrow model that could comfortably fit into any room (like tower fans). The unit is just barely 30 inches tall, with a 9.2 by 7.3-inch base. The product has a tall grey shell with a digital screen near the top and several control options on the top side. That modern design is further helped by the convenient carry handle in the back.

Lasko Ceramic Tower Space Heater with Logic Center Digital Remote Control-Features Built-in Timer and Oscillation, 7.3″L x 9.2″W x 29.75″H, Black 5572

The heater has a timer feature that can postpone the shutdown up to 8 hours. It also has a remote control. Let me tell you, those are very nifty features to have. Trust me — once you’re all warm, you won’t want to get up.

Since this is a ceramic unit, it does have internal fans that allow the hot air to oscillate up and down. However, according to the users, it remains completely silent on both heat settings.


  • 1,500-watt ceramic tower heater
  • Tall and narrow for easy fit
  • 2 heat settings and an Auto feature
  • Adjustable thermostat, timer, and remote

2. DeLonghi HMP1500 Mica Panel

The Delonghi Mica Panel is another 1,500-watt heater with some serious portability features. It’s a silent micathermic heater that’s about 27 inches wide, 10 inches thick and 22 inches tall. It also has 4 wheels holding the panel up. The feet are fully removable, though, and you can even mount it on a wall with an included kit.

If you decide to keep it on the floor, you should be happy to know that it has an internal tip-over switch. The unit has 2 heat settings that are adjustable via a dial located on the right side of the panel. It even has an adjustable thermostat you can get to with the other dial. And, although it’s a 1,500-watt heater, it can heat up to 300 square feet.


  • 1,500-watt micathermic panel heater
  • 2 heat settings
  • Adjustable thermostat
  • Tip-over switch
  • Wall-mountable

3. Bionaire Silent Micathermic Console Heater

This Bionaire heater is another micathermic unit that’s 26 inches tall, 6 inches thick and 21 inches wide. Similarly to the previous heater, it’s a 1,500-watt heater with great mobility. However, while the previous product has four removable wheels, this one only has two wheels on one side, and a handle on the other, so you can drag it from room to room.

Like the previous devices, this unit has 2 heat settings and an adjustable thermostat. The main control settings are on the side of the heater with the handle on it. One switch turns it on and off, another allows you to choose between low and high heat, and the big dial lets you adjust the temperature. Additionally, this heater has both tip-over and overheating protection features.


  • 1,500-watt micathermic heater
  • Good mobility
  • 2 heat settings
  • Adjustable thermostat
  • Overheating and tip-over safety features

4. TURBRO Arcade Electric Mica Heater

Like the previous products on this list, this TURBRO device is a 1,500-watt micathermic heater. It also uses silicon to produce infrared light waves to evenly warm the space without consuming water or oxygen. And, even though the heater is capable of running on 1,500 watts of power, you can also use the low setting to limit it to 1,000 watts.

What’s more, this product also has an adjustable thermostat that can take you between low and high temperatures and even engage the energy-saving feature. In fact, the device also has overheating and tip-over protection. But, although it says it’s waterproof, you apparently shouldn’t use it in humid areas like bathrooms and laundry rooms.

The design of this heater is fairly standard, though it comes in black and white, which is a first. It’s also about 26 inches tall, 17 inches wide, and 10 inches thick. However, you should keep in mind that the panel itself is actually much slimmer, and the 10-inch thickness is all in the stable platform. Speaking of which, this heater also has 4 wheels and handles on both sides, so you can roll it anywhere you want it to be.


  • 1,500-watt micathermic and silicon heater
  • Several low and high heat settings
  • Energy-saving mode
  • Adjustable thermostat
  • Overheating and tip-over safety features

5. Dr. Infrared Heater Portable Space Heater

This 1,500-watt Dr. Infrared Heater is almost half the size of previous devices, but it packs a strong punch. The little heater is only 16 inches tall, 11 inches wide, and a bit over 13 inches deep, with 4 swivel wheels on the bottom. Still, despite its diminutive size, it may actually be heavier than some of the others I’ve mentioned. And even though this heater should by all accounts only be able to cover 150 square feet, the manufacturer actually claims that it can heat up to 1,000 square feet.

Dr Infrared Heater Portable Space Heater, 1500-Watt

In my opinion, this box-shaped device is one of the most attractive heaters on this list. All but the front side is covered with beautiful cherry wood, which is a welcome break from the other metallic finish heaters. On the other hand, the front side of the heater is completely black, with only the top third of the space emitting infrared heat. Naturally, the controls are right under that pan, although the heater also has a remote control.

The temperature can be set to high, low, and automatic setting. You can also choose the temperature you want the device to maintain and let it do its thing. It will shut down automatically after 12 hours, and it also has overheating protection. Additionally, although I wouldn’t say that it’s necessary due to the heater’s shape, it has tip-over protection as well.


  • Portable 1,500-watt infrared heater
  • Cherry wood exterior
  • 2 temperature settings and an adjustable thermostat
  • Remote control
  • Overheating and tip-over protection

6. iLIVING Infrared Portable Space Heater

Similarly to the previous product, this iLIVING infrared heater is box-shaped and encased in wood. It also has the swivel wheels at the bottom and a remote control. However, the wooden case isn’t quite the same color as on the previous model, but rather a “Dark Walnut” wood. Furthermore, the front side of this device also has a wood panel, unlike the previous one.

New iLIVING Infrared Portable Space Heater with Dual Heating System, 1500W, Dark Walnut Wooden Cabinet

Other than those features, these two products are much the same. They’re both 1,500-watt infrared heaters that claim to be able to cover 1,000 square feet areas. They also both have overheating and tip-over protection features. This one is a bit smaller overall, measuring in at 15 inches tall, 12 inches wide, and 13 inches deep.


  • Portable 1,500-watt infrared heater
  • Cherry wood exterior
  • 2 temperature settings and an adjustable thermostat
  • Remote control
  • Overheating and tip-over protection

7. OPOLAR 1,500 W Digital Space Heater

The next smallest device on our list is attractive enough in its own way. The OPOLAR heater comes from a manufacturer you may be familiar with if you’ve read any of my quiet fan reviews. If you are looking for the perfect small, portable heater, this may well be it.

Standing at barely 14 inches tall, this heater has not only a handle but also a sturdy stand that holds its body while it oscillates 85 degrees left and right. This ensures an equal distribution of the heat — but that’s not even the best part.

In fact, the device has 3 modes. The hot mode uses 1,500 watts, the warm uses only 1,000, and there’s also a cool wind mode that only uses 20 watts. Apparently, the device does have a removable air filter as well, which makes it exceedingly easy to clean.

In addition to the 3 temperature modes, this heater has a timer that can be set between 1 and 8 hours. Also, it will shut down automatically once it reaches the temperature you’ve set using the thermostat. Naturally, you can see all of these settings on the digital LED display at the top of the heater.


  • 1,500-watt portable oscillating heater
  • Timer, adjustable thermostat
  • 3 heat settings including cold
  • Tip-over and overheating protection
  • LED display

8. PuraFlame 1,250W Small Portable Electric Heater

The PuraFlame heater is another truly unique-looking device on the market. It’s only 12 inches tall, 9 inches long and 5.7 inches wide. All of the settings are at the top of the device, and there’s an easy-carry handle in the back as well. But the endearing part of this heater is the fact that there’s an LED display at the front showing a coal fireplace right above the metal grill that lets the heat out.

The features are just as impressive. This 1,250-watt device can serve as a supplemental heating device to a 400 square foot room — according to the manufacturer. In fact, I could have used a heater like this one in my college days.

As I have mentioned, there are two control dials on top of the device that control the display and the thermostat. Also, since this device is so small, I’m happy to report that it also has overheating and tip-over protection.


  • 1,250-watt portable heater
  • Fireplace LED display
  • Heat setting dial
  • Adjustable thermostat
  • Overheating and tip-over protection

9. Lasko 5409 Ceramic Portable Space Heater

This Lasko space heater is a small unit with a handle. It is just under 12 inches tall, 8 inches wide and about 6 inches deep. Unlike the previous model, it doesn’t have the ability to oscillate side to side. But, despite having a stationary stand, it can oscillate internally to shuffle the hot air through the area.

Lasko Ceramic Portable Space Heater with Adjustable Thermostat - Features Widespread Oscillation to Distribute Warm Air, Silver 5409

All of the controls are at the top of the device. The oscillation button is between the heat and the thermostat dials. The heat dial allows you to choose between the fan setting and high or low heat, while the thermostat allows you to set your preferred temperature. What’s more, the exterior of the device should remain cool to the touch, and the heater will automatically shut down if it’s been on for too long.

  • 3 settings: low/high heat, and fan only
  • Adjustable thermostat
  • Overheating protection, cool to the touch

10. iVAPO 500W Mini Personal Space Heater

The smallest space heater on my list is also the least powerful one. The 500-watt personal space heater from iVAPO is only 10 inches tall, but the 60-degree oscillation allows it to distribute the heat more evenly. Although this small heater does have tip-over and overheating protection, the settings essentially come down to the on/off button.

Final Thoughts on Quiet Space Heaters

Investing in a quiet space heater can really change your winter. But before you take your pick, you need to know what’s out there. Hopefully, this article has managed to shed some light on that. And, if you haven’t quite found the perfect heater for you, at least you now know what features you should keep in mind when you go shopping.

Before you decide, keep in mind the rooms you’ll be using the heater in. Consider whether you’d want a device that instantly heats up the area or one that would be a more economical choice for constant heat. If you’ve got extra space, you can get one of the heaters I’ve mentioned at the beginning of my list. On the other hand, if you really don’t have room to spare, get one of those I’ve closed with.

Ultimately, there’s a quiet space heater for everyone. So as long as you know how to choose the one that will be best suited for you, you’ll be just toasty!
