1. Mr. Heater F299831 Vent-Free Radiant Natural Gas Heater

Safe and comfortable is what the Mr. Heater F299831 radiant heater guarantees. It’s designed for supplemental heating, but it can spread warmth over spaces of up to 1000 square feet.

Plus, this device has built-in oxygen depletion sensors (ODS), which allow the device to shut down automatically when the room’s oxygen level drops below the normal volume. Radiant or infrared heaters are known for their healthy way of warming spaces. Match that with ODS and you got yourself an innovative, body-friendly heating solution.

This vent-free heater runs on natural gas, so it makes a great option if you want to cut down your home’s electricity consumption or you just want a backup heater for times of power outage. If you’re concerned about control, don’t worry—this heater comes with a thermostat and a battery-powered ignition. If you want, you can also get a blower fan kit (sold separately) from the manufacturer to boost how it spreads warmth.

Depending on your room layout and personal preference, you may position a Mr. Heater radiant heater on the floor using its removable legs or mount it on a wall using brackets (included in the package). This radiant heater is pretty stylish, so it can blend easily with most room designs. But word of caution: it isn’t recommended for bedrooms, bathrooms, and altitudes over 4,500 feet above sea level.

Pros Great for spaces up to 1000 square feet. Comes with electronic ignition, thermostat, oxygen depletion sensors with an automatic shut-off system, and mounting hardware.

If you are fond of elegant and sophisticated radiant heater designs, you’d probably like the De’Longhi Full Room Radiant Heater. It features high-quality steel construction, patented thermal chimneys, and permanently oiled reservoir. The benefits? Effective and efficient heating without excessive surface heat.

Because of that, you wouldn’t have to worry about your children or your pets while you use the heater. Even if they (or you) accidentally touch this radiant heater’s surface, the temperature wouldn’t be too hot to cause injury.

This heater is oil-filled, but as many buyers mention in Amazon reviews, it isn’t like the typical oil-filled heaters that create an unpleasant smell. Its oil reservoir is permanently filled and sealed, so there’s no need for a refill—ever.

If you’ve used a De’Longhi heater in the past, you might notice that the TRD40615E heater is an improved design. Compared with older De’Longhi heaters, this one has larger fins that help improve airflow. It also boasts of silent operation technology, which many users look for when choosing a heater. It’s great for zonal heating, especially in rooms where you need to work or rest.

On top of that, this heater offers three heat levels and an adjustable thermostat. If you find that the prescribed levels aren’t suitable for your room’s condition, you can take matters into your hands. This heater also has an anti-freeze setting, so you won’t have to worry about frozen pipes.

Pros Great for spaces up to 144 square feet. Features patented steel assembly, permanently sealed oil reservoir, silent operation, adjustable thermostat, thermal cutoff function, and anti-freeze setting. Comes with a 6-foot long cable and pre-assembled castors.

3. De'Longhi KH390715CM Oil-Filled Radiator Space Heater

There’s no doubt that De’Longhi makes innovative heater designs. If you check out other radiant or infrared heater reviews, you’d see that this brand is almost always mentioned more than once. That’s actually beneficial because it provides options for different heating needs. For this case, for example, the KH390715CM heater model offers a great option for small rooms up to 45 square feet.

With its modern and elegant design, this heater has provided an affordable option for many. Not only does it require a smaller upfront investment, but it’s also cheaper in the long run because of its Real Energy Technology and Comfort Temp sensing system. The former makes the heating process faster as well as cheaper, while the latter keeps the temperature at 22-degrees once the heater achieves it. These technologies make the machine not only energy-efficient but also more eco-friendly.

Aside from that, this oil-filled radiant heater requires very little maintenance. It doesn’t require oil refilling because its reservoir is permanently sealed—you’ll just have to keep the external clean and that’s it. Of course, it goes without saying that you should also make sure to follow the manufacturer’s instructions for proper heater usage.

As for temperature control, this radiant heater provides three heat settings and an adjustable thermostat.

Pros Great for spaces up to 45 square feet. Features a permanently sealed oil reservoir, Real Energy Technology, Comfort Temp sensing system, adjustable thermostat, and thermal cutoff function. Comes with patented SmartSnap wheels.
Dimensions 15 x 35 x 63 inches / 22.1 lbs

4. De’Longhi TRD40615T Dragon4 Programmable Portable Radiator Heater

This Dragon4 radiant heater has a portable design that’s great for residential use as well as for medium to large offices. Compared with the older Dragon3 models, this one has a larger radiant surface, which results in better airflow and better heating.

Though this heater is an oil-filled type, you will never need to refill its reservoir. Its reservoir is permanently sealed and does not require any maintenance. Plus, it’s built for silent operation, so you can relax or stay productive while the heater does its work.

Like most modern heaters, this radiator offers multiple heat settings. If none of those settings achieve the temperature that you want, it also has an adjustable thermostat so you can customize and personalize your way to your desired temperature.

Some users say that this heater sometimes takes a while to achieve the set temperature. However, once it does, it can provide a great full-room warmth that benefits users as it protects against frozen pipes through its anti-freeze setting.

Additionally, this heater also has a programmable timer. It allows you to set the times of the day when the heater should go on or off, so you won’t have to worry about changing the settings daily.

Dimensions 16 x 6.5 x 25 inches / 24 lbs

5. Aikoper B07TP3JWS7 Oil-Filled Electric Portable Heater

Powerful, efficient, and user-friendly are some of the things that people have to say about this heater by Aikoper. Its 24-hour timer, digital thermostat, and large LED display make it convenient to use. It also has multiple heat settings—low (600 watts), medium (900 watts), and high (1500 watts)—that allow for a quick setup.

This oil-filled heater is great for medium to large rooms. Additionally, another great thing about it is that you don’t have to install it permanently on one spot. It’s designed to be portable and is built with caster wheels, so you can easily move it from one room to another as needed.

Aside from that, here are other features of this Aikoper heater that buyers from Amazon are amazed by: low noise level, convenient remote control, tip-over protection, and energy efficiency. This device is built with ECO mode—a feature that automatically adjusts the heat settings as necessary, thereby decreasing energy consumption and, consequently, your electric bill.

If you have children or pets, the Child Lock function would be great for you. It dramatically reduces risks of common heater-related injuries, particularly skin burns caused by the surface heat. And of course, because this heats up objects instead of the air molecules, the warmth produced is healthier and unlikely to cause skin issues.

Pros Great for medium to large rooms. Features silent and easy operation, Child Lock function, digital thermostat, 24-hour timer, LED display, and overheat & tip-over protection. Comes with caster wheels, remote control, and batteries.

6. PELONIS B07XRP9M3F Luxurious Gold 2019 Oil Filled Radiator Heater

This PELONIS portable space heater combines luxurious and affordable in one device. Many buyers like it for its effective heating capacity, but its elegant design makes people like it even more.

Its champagne gold color can add a touch of sophistication to any room. It’s also user-friendly, especially with its digital thermostat, 10-hour timer, LED display, and remote control.

This oil-filled heater has three heat settings (high, low, and ECO) and five temperature options (65 to 85 degrees Fahrenheit). Unlike ordinary heaters, this one is safe to use for prolonged periods. It works without a fan, so it doesn’t produce a breeze that can cause skin irritation or breathing problems on people who are sensitive to allergens.

On top of that, real-customer product reviews say that this radiant heater is super quiet, except for the occasional and normal clicking sound made by the thermostat. One common negative comment, however, is that the warmth can get too warm. To avoid that problem, it’s advisable to use the device in medium to large rooms only. For small spaces, be sure to adjust the temperature accordingly.

Like most modern heaters, this PELONIS heater comes with overheat and tip-over protection. If you accidentally hit it and it gets knocked over, it will automatically shut down to protect you as well as the people and assets around you.

Pros Great for medium to large rooms. Features silent operation, digital thermostat, 10-hour timer, LED display, and overheat & tip-over protection. Comes with caster wheels, remote control, and batteries.

7. De’Longhi TRH0715 Oil-Filled Radiator Space Heater

Another bestselling De’Longhi electric oil-filled radiator is the TRH0715 heater. Its design is made for providing full-room warmth for spaces up to 250 square feet. Its oil reservoir is also permanently sealed, so it will not require oil refilling regardless of how frequently it is used.

Its patented thermal slots help improve heat flow while maintaining a non-injurious surface temperature. As such, it is relatively safer and child- and pet-friendly than most heaters without thermal slots. Many users also say that this heater is very easy to use; its heat setting is easy to manipulate and can even be customized with the use of the built-in adjustable thermostat.

This heater also has a thermal cutoff function. What it does is it automatically shuts down the device when it overheats or someone accidentally knocks the device over. This heater is also easy to move from a place to another because of its caster wheels; if putting a heater in one spot poses risks to the device or the people around, it will be easy to reposition it at another safer area.

Some customers say that their TRH0715 heater sometimes gives off an odd smell. To avoid that, you can follow what some HVAC professionals recommend: use the oil-filled heater in a well-ventilated area for several hours before using it in a confined room.

Pros Great for spaces up to 250 square feet. Features patented steel assembly, permanently sealed oil reservoir, adjustable thermostat, thermal slots, thermal cutoff function, and anti-freeze setting. Comes with pre-assembled castors.

8. AmazonBasics Indoor Portable Radiator Heater (White)

If you’re looking for a modern and ETL-listed portable radiator, this heater by AmazonBasics might be great for you. The ETL certification is a widely recognized proof that a product has been tested and proven to be compliant with relevant industry standards, so it’s undoubtedly a good thing to look for when buying a heater.

Also, if you or someone in your family finds it challenging to work with a digital thermostat, this heater can take you back to simple-to-use controls. It has two knobs that you can use—one for manually adjusting the thermostat and another for choosing between three heat settings.

This radiant heater also boasts of an innovative, permanently filled and sealed oil reservoir. It has a total of seven filled fins that help ensure maximum comfort with little to no maintenance required. Its steel construction is also rust-resistant, so it can provide a long service life and save you from rust-related worries.

In terms of safety features, this AmazonBasics heater goes beyond the basics. All its heating elements are fully enclosed and its base is made with non-slip material to protect the device from tipping over and causing injures or fire. It also has an automatic shutoff feature that works when the device overheats. On the other hand, if the temperature goes below a specified level, the anti-freeze setting will automatically turn the device on to prevent frozen pipe issues.

9. AmazonBasics Indoor Portable Radiator Heater (Black)

Not into white devices? No worries. The AmazonBasics indoor radiator is also available in black. This design has all the features of the white variant, such as, among others, the ETL listing, rust-resistant steel construction, and permanently sealed and filled oil fins.

According to real-life customer reviews, this radiant heater is easy to assemble and easy to use. Considering its price, some people say that its features are worth the investment. Plus, though it’s oil-filled, the heating process is quiet and ideal for bedrooms and workspaces.

A problem that some people report, however, is that the knobs are difficult to hold and move, especially for the elderly. For cases like this, it might be best to use a heater with a digital thermostat. However, if you prefer a simple, knob-type design, then this AmazonBasics machine is worth considering.

A few other things that users like about this heater are its lengthy cord, cord storage, and no-assembly-required wheels. The cord is 72-inches in length, which is convenient for places with limited electrical sockets.

If you purchase this heater and you encounter any problems, you may use the one-year warranty to request a product repair or replacement.
