“Sorry to interrupt; what’s that clicking noise? Can you tone it down so I can hear you please”

Quietest Space Heater

What an embarrassing way to start an important meeting with a new client!

I had no choice but to turn the annoying portable heater off, rush back to the zoom meeting, and close the deal in the cold.

This is my near-sad story and why I switched to a quiet space heater.

But with space heaters NOT created equal, choosing the right one can be tricky.

Luckily, I’ve written this post to be the ONLY guide you’ll ever need to shop right. But before I share my top 5 quietest space heaters, here is some important information to know:

In a Hurry? Here’s a Summary of the 3 Quietest Space Heater

De’Longhi MicaThermic Panel Heater – is the most VERSATILE option, offering unbelievable value for money. Its TWO heating settings, wall-mount or freestanding design, and ground-breaking MicaThermic Technology. Its sun-like warmth covers up to 300 square feet of space and has no fans to create sleep-depriving NOISE.

Dr Infrared Heater – is a set-and-forget space heater. Its AUTO mode helps reduce power consumption and save more on utility bills. This model’s Dual Heating System offers incredible warmth for a whole family. It has the HIGHEST coverage, up to 1000 sq. ft., for such a small space heater.

Dreo Space Heater – is an EXTRA portable space heater. It has one of the world’s best Ceramic Heating technologies. It delivers warm haze covering a 200-square-foot bedroom or office. This mobile device features the right safety features like Overheating & Tip-Over Protection.

How Does a Space Heater Work?

 Space heaters are portable alternatives to the central heating system. The working principle behind these heating devices differs:

  • Conventional space heaters have heating plates generating heat distributed by convention or built-in fans.
  • Radiant models emit infrared radiation to heat bodies or objects. These gadgets won’t warm up the air.

Type of Space Heater

Ceramic space heater

 This type features a ceramic plate fitted to an electric metal coil. The plate transforms the absorbed electrical energy into massive heat.

Ceramic space heater

The top-selling point of ceramic models is their instant warm-up to escape the chill. Also, it features a safer design since its exterior casing stays cool to the touch.

But there’s a flaw.

Its heating performance is excellent for smaller areas. But, it tends to perform below par when moved into spacious rooms, except it has built-in fans.

Fan-forced space heaters

The fan space heaters share a lot of similarities with the ceramic model. But they differ in terms of the heating element.


This type generates the heat using a metal coil instead of a ceramic heating plate. The resulting heat spreads with an integrated fan to offset your drafty room. It’s cheaper and usually compact, making it an excellent choice for small apartments.

 Downsides? They tend to dry up the air and make the space difficult to breathe in.

Infrared space heater

An infrared space differs from the other types I’ve discussed so far. It’s powered by electricity and emits EM waves in one dimension for direct heating. This model won’t warm up the entire room but anything, including human bodies in its path.

 Oil-filled space heaters

 Most people refer to this device as a “radiator heater.” It relies on the diathermic oil to generate and transfer the heat to the fins. At this point, the heat offsets your drafty room by convection or fan-forced.

Oil filled space heaters

But the best thing about oil-filled heaters is their long-lasting warmth. This device comes with wheels for easy maneuvering.

Now, the bad part includes uncontrolled heat speed and its tendency to get the space too hot for your liking. Plus, the exterior casing gets hot and unsafe to touch.

Panel space heaters

These are the latest heaters with revolutionary technology and distinctive design. These space heaters use electric currents to heat the air and radiate off its flat surface. They are either installed on the floor or mounted on the wall.

Propane space heaters

The propane space heater is the way to go if you want to avoid using electric-powered heaters. It runs on liquid propane and delivers the hottest heat amount. Plus, you can save up to 20% if you fuel your heater with LP instead of connecting it to a power source.

Propane space heaters

But, the risk of fire and explosion can be scary for most homeowners. Plus, the cheap ones might emit carbon dioxide, CO2, which is bad for your health.

Why Do Space Heaters Make Noise?

 There are two reasons why a space heater might be making a noise, and it’s not for the wrong reasons. These devices consist of metal components expanding and contracting due to heat changes. This explains the cracking noise generated by these devices.

According to electronic experts, the noise source might be the relay switch. This component switches on and off to control the temperature. This causes the clicking noise.

But, the noise should be subtle and in the background. Anything apart from this might herald a faulty appliance. In this case, you should stop using the device immediately for safety reasons.

Which Type Of Heating Method Is Quietest For Room Heaters?

 Do you remember that heaters warm your space or body using one of the two methods? The infrared space heaters are WHISPER-QUIET and won’t affect your sleep quality.

But, models that rely on airflow come with built-in fans to distribute the heat, which means more noise. 

But before you run to an online store to shop for any radiant heaters labeled as “quiet,” you might want to hear this:

 Radiant heaters are the quietest space heaters, but they take longer for the warmth to hit you. Also, its heating is one-directional. The consequence? Everyone scrabbles in front of the device to enjoy its sun-like heat.

How to Choose a Quiet Space Heater for Home and Office

 Heater Build Quality


Manufacturers make the exterior casing with a wide range of durable materials. But, metal casings expand and contract as the temperature changes, which generates noise. So, if you don’t want an embarrassing heater, stay away from the metal casing.

On the contrary, plastic casings do not experience thermal stress. Thus, they make up the best quiet space heater for offices and bedrooms.


If it’s not the casing at fault, I’ll poke my hands at the integrated fan. How much noise this component generates depends on its speed and size. At higher speeds, the airflow increases, causing more disturbance and loud noise. Also, the bigger the fan size, the louder the noise. Hence, a product with small fans is great for silent allies during winter.


Shoppers often mistake oscillating heaters for lousy products. Cheap models will likely make a loud noise because these manufacturers cut corners.

But there’s a benefit to it;

Oscillation helps speed up the heat distribution. But, it is NOT a deal breaker if a space heater lacks this function.

 Adjustable Thermostat

Every space heater will make a clicking noise from the thermostat when you turn it on and off. It’s not annoying or irritating; you will stop paying attention with time. You have to find a way to live with this noise.


Infrared or halogen heaters emit light radiation. The infrared red light heats the bodies or objects on its path. They are no good for warming up an entire room since it emits IR in one direction.

On the bright side, there’s NO need for a fan, which means utmost tranquility in the warm haze.

But what about the other two heating methods?

Resistive or fan-forced and oil-filled heaters rely on convection heating. This method of heating has a downside: whooshing noise from the fans.

Ceramic/resistive Heaters use PTC materials to convert electric energy to thermal energy. The process is called joule heating. Not as if you need to know this technical jargon anyway. The PTC resistors transfer this heat to the aluminum fins through conduction. The last stage involves blowing off the heat in the room.

 Are fans essential?

It depends. A fan is essential if you want heat efficiently distributed around a room. The downside is you might have to put up with the noise.

We are down to the last heating method – oil radiators. They share some exciting features with resistive heaters. Instead of PTC material, this type uses an oil reservoir submerging a heating element. The heated oil flows to the fan and to the casing, dissipating it to the room by convection or blown by a fan.

By convection, I mean that the heated surface of the radiator warms up the nearest cold air. The process continues until the entire space is no longer chilly. The natural convection cycle takes longer than fan-forced models. But it won’t stir up dust and dirt in the room.


Most models come with a 1500W heating element. But this doesn’t tell you how much heat the device can generate.

The household electric outlet is 12A, 120V, ideal for devices lower than 1800W. Using any higher power device for an extended period might lead to fire and explosion.

This explains why most space heaters, small or large, have the same 1500W heating element.

Furthermore, running a portable and large space heater for the same period will cost the same. But, don’t expect the same heat output, which hinges on the number and type of heating methods utilized.


Manufacturers are always in a hurry to tag their devices as “Quietest Space Heaters.” Don’t fall for cheap marketing. Instead, check the decibel rating of the device. Anything higher than 50 dB will be a nuisance anywhere it’ll be placed, office or home.

Another trick to choosing the quietest space heater is avoiding fan-forced appliances. The massive air movement contributes to the noise level. You can’t go wrong with an oil-filled radiator or an infrared heater for bedroom and office use. They are the favorites for silent operations.

Protection and Safety

This is the most ignored factor by shoppers. Portable space heaters get hot and unsafe to touch. So, consider a unit with a cool-to-the-touch exterior casing if you’ve kids.

Also, they can explode or start a fire. Hence, it would be best if you shop for space heaters with several safety features. On the lookout should be an AUTO shutdown function for utmost protection if tipped over. Also, check for Overheating Protection to protect the device and your property.

Alternatives Of Space Heater

In some ways, space heaters have revolutionized this industry. Still, other heating options can be your ally throughout this winter.

Electric Wall Heaters

These hulk-like devices are mounted on a wall and can push out two times the heat output of space heaters. But don’t expect twice the noise; why? These wall-mounted heaters rely on their radical build quality to dampen the noise.

Mini Split Air Conditioners

 If you second-guess a space heater, you might want the mini split AC. This option offers the best of both worlds — portable heaters and central HVAC systems.

If I don’t have to move a heater from one room to another, I’ll put my money into mini split air conditioners. They run quieter and knock out more heat than space heaters. Also, compared to space heaters, mini split AC has a better build quality for higher longevity.

Central HVAC systems

The central heating system is efficient in many ways, except for energy. Central HVAC system sucks up an unnecessary amount of power to heat several rooms and spaces no one is in. The sad result is expensive utility bills.

Central HVAC systems offer whole-housing heating. They are not portable, so they pack great power to warm up large spaces. So, there’s no need for people to clash in front of the one-dimensional radiant space heater.

Need the Best Quiet Space Heater For Office? Listen to These Experts’ Advice

Most manufacturers claim their products are suitable for both office and home use. This is far from the truth.

Most of them make a cacophony of noise, distracting and affecting your productivity. The suitable model should be able to put out enough warmth without making noise.

This means you don’t need those loud fans for distributing heat. Except you are looking to buy an appliance to warm up several workers in a room. If not, your best bet is an Infrared heater rated 1000W or lower. Besides, you’ll be saving up to 40% going that route.

The MOST Important Factors to Consider When Shopping for a Home Space Heater

Most models will come with a 1500W heating element, so don’t worry about those. Instead, focus on the PTC material, fan size, degree of oscillation, etc. Here are the SECRET tips, according to top electronic specialists:

For living rooms, fan-forced units can be ideal since there’s usually a lot of noise from TVs, the kitchen, etc. The bedroom and office need a silent heating device like a radiant space heater. Also, convention-based models with no fans can be a decent appliance for bedrooms and other serene areas.

But, most electronic specialists suggest avoiding fan-forced portable heaters for the bedroom. Their loud noise can upset your room’s quiet ambiance and affect your sleep quality.

Tips for using Space Heater

Space heaters are supplementary tools, providing extra warmth to make all the difference. They may seem like an angelic tool, but it’s not and can be dangerous if handled carelessly.

So, keep these three main tips in mind for your home’s safety:

  • Place the heaters strategically away from walls, furniture, wet items, and water.
  • Try not to use the space heater overnight.
  • Ensure the device comes with safety features and relevant certifications.

Do space heaters use a lot of electricity?

They might vary in size, but they are equipped with a 1500W heating element. This means these devices consume the same amount of electricity and cost the same to run. But, some products offer two heat settings.

For instance, DeLonghi MicaThermic Panel Heater offers 750W and 1000W. This proves effective for avoiding unnecessary power consumption.

Are space heaters energy efficient?

Technically speaking, almost all space heaters are energy efficient. They convert more than 90% of the electric energy into thermal energy.

So, when you hear a manufacturer screw 100% energy efficient, know it’s nothing special.

What size space heater do I need?

The trick is: every square foot of room space needs 10W of heating power. So, if you have a room with 110 square feet of floor area, the heater should come with a 1100W heating element. To be on the safer side, it’s best to compare the device’s coverage with your room size.

Can you sleep with a space heater on?

Electronic specialists suggest turning off your portable space heater before going to bed. This helps avoid being unaware of the fire breaking out or the smoke growing. But newer models have more safety features to prevent overheating or fire.

Are Space Heaters Allowed In Office Buildings?

The cold haze is everywhere. Thus, the application of space heaters extends to office use. If your office lacks a central heating system, you might buy the best quiet space heater for the office.

If you already own a portable home model, it should provide you with enough warmth at work. Also, no federal law prohibits workers from using a space heater at their workplace.

But OSHA’s strict rule demands workers follow the instructions in the manual and label.


Investing in the quietest space heater provides enough warmth for a comfortable winter experience. But, several options and factors must be considered before making a choice. It can be overwhelming and daunting.

Hopefully, this post is the ONLY guide you need to make the right decision. Most of the products on this list are super quiet, but they are not created equal. Hence, I recommend reading the buying guide to ensure you are making an informed decision.
