I recently purchased this heater while waiting for HVAC parts to arrive, and I must say it has exceeded my expectations. Despite its small size, it has been able to keep my bedroom warm during several cold nights (with outside temperatures as low as 28°F).

One of the things I love about this heater is that it operates silently and doesn't produce any smoke, smell, bright lights, or noise. This makes it perfect for using while sleeping or working. Additionally, it is very easy to move around as it has a portable design, and I appreciate the fact that there is no risk of getting burned while it's running.

The heater also comes with a remote controller that has a battery included. This allows me to adjust the temperature and settings without having to get up, which is very convenient.

The safety features of this heater are impressive as well. It automatically turns off if it reaches a temperature above 120°F, preventing any damage to the unit or its surroundings. This gives me peace of mind, especially when using it in my bedroom or any other enclosed space.

The heater is also energy-efficient, thanks to its ECO mode that adjusts the heating based on the ambient temperature. This not only saves energy but also saves me the hassle of constantly adjusting the settings.

In terms of design, it is clear that a lot of thought has been put into it. The digital screen on the front provides clear information about the heater's operation, and the overall build quality is excellent.

While I initially bought this heater for my outdoor observatory, I am confident that it would work just as well in any indoor room. Its power and safety features make it a reliable and efficient heating solution.

Considering the performance and features it offers, the price of $90 is truly a bargain. I highly recommend this heater to anyone in need of a compact and powerful heating solution.

I recently purchased three of these heaters for my 2 thousand square foot home, and I must say, they have exceeded my expectations. Not only are they cost-effective, but they have allowed me to completely turn off my natural gas supply. The cost of running these heaters is significantly lower than my previous natural gas charges for the past two months. I strategically positioned two of the heaters near intake vents to optimize air circulation and filtration. By setting my HVAC fan to auto-run for 15 minutes per hour, the air quality in my home has greatly improved.

Even in freezing temperatures of -10 degrees Celsius outside, my home remains stable at a comfortable 20 degrees Celsius with all three heaters set to medium and the thermostat at 75%. The basement placement of two units takes advantage of hot air rising and enhances overall efficiency. Additionally, I am able to leverage the solar production from my solar panels, which I installed two years ago, to power these heaters. With the installation of an electric water heater last year, I have successfully eliminated the need for natural gas in my home. In fact, my gas bill for the last two months has exceeded my entire year's spending for gas in 2021.

These heaters have proven to be a wise investment for me. The stability of electricity costs at ten cents per kilowatt hour for decades further solidifies their value. Furthermore, the solar production ensures that the exchange in heat energy is not only cost-effective but also environmentally friendly. I am extremely satisfied with this heating solution and highly recommend it to anyone seeking an efficient and reliable way to stay warm during the winter.

On a separate note, I also live in a travel trailer, and the past few years have been a struggle to stay warm. The lack of insulation in travel trailers often leaves me feeling cold, and my previous space heater even posed a fire hazard. However, after some hesitation, I decided to give this heater a try, and it has been a game-changer. The first night I used it, I woke up without freezing cold hands and face for the first time since living in a travel trailer. This heater has provided me with the warmth and comfort I have been longing for.

I've come across reviews where people complain about the heater light staying on while plugged in, but the instructions clearly state that the light remains on as long as it is plugged in. Therefore, I don't understand why this is an issue for some users. Additionally, I noticed that the lowest setting doesn't produce any heat at all, and the heater remains cool to the touch. This is something to keep in mind when adjusting the settings.

I recently purchased the "Amazon Basics Portable Radiator Heater with 7 Wavy Fins, Manual Control 1500W" in December 2022, and I am quite satisfied with its performance. However, it is important to note that the top of the heater can get hotter than expected, so caution is advised.

The heater operates silently even when running continuously on high for 24 hours. It efficiently heats up a 10'x17' room in approximately 45 minutes, starting from a temperature of around 62ºF. The heater continues to raise the room temperature over the next few hours. It is worth mentioning that in colder weather, it may take longer for the heater to reach the desired temperature.

In comparison to the Vornado MVH Vortex heater, which costs $9 more, the Amazon Basics heater performs significantly better. I regret not purchasing a second Amazon Basics heater instead of the Vornado. Additionally, I anticipate that fan-type heaters may encounter issues with the motor or dust clogging within the first year of use, and cleaning their fan blades can be challenging.

Personally, I do not utilize the thermostat control feature. During the initial use, the heater emitted a metallic odor for a few days, so it is advisable to place it in a garage or outdoors during the first several hours of operation. After 2.5 months of use, I can confidently say that the heater works remarkably well, exceeding my expectations, and it is reasonably priced.

Despite the smaller size of the Radiator Heater compared to my initial expectations, I have prior experience using similar heaters in a small house in the Arkansas Foothills several years ago. Two of these heaters effectively kept the entire house warm, even during snowy winters. Therefore, I am confident that this 1500 watt heater will sufficiently warm my RV trailer. Once heated, I plan to adjust it to a low setting to maintain a comfortable temperature throughout the night, regardless of how cold it gets. Living in Southwest Louisiana, near the coast, this heater will be essential for my retirement plans of living in a tiny home and traveling between parks. I am highly satisfied with this purchase.

While I acquired this heater used but in like-new condition for $51.98, I did encounter a minor setback as the remote was missing. I reached out to customer service, requesting a replacement remote, but unfortunately, they were unable to accommodate my request. Instead, they offered a refund and advised me to return the item. Since the heater functions perfectly fine without the remote, I decided to keep it and use the buttons on the unit itself. Although it is important to note that this heater cannot be turned on using a smart plug.

It is worth mentioning that this heater provides radiant heat, which means it does not warm the air directly. Instead, it heats objects and people in close proximity, similar to the warmth provided by campfire coals. While it may effectively heat a room, it is best suited for providing focused warmth in a larger forced-air heated home.

I recently purchased this radiator heater and I am extremely satisfied with its performance. One of the standout features of this heater is its temperature control, which is highly accurate and aligns perfectly with my thermometers. Unlike fan forced directional heat, this radiator heater provides a more comfortable and evenly distributed warmth.

I have used other radiator heaters in the past, but this one stands out due to its functionality. It heats up remarkably fast compared to regular units on the market. Although it may seem expensive initially, I was fortunate enough to grab it on sale for under $100, which is double the price of the cheapest options. However, I firmly believe that this radiator heater is worth the investment.

Living in a small house, I often struggle with maintaining a constant temperature. The air volume is limited, causing the temperature to drop quickly once the furnace shuts off. However, with this radiator heater, I finally found a solution. It keeps my room cozy and maintains a consistent temperature, providing me with peace and quiet. If I used the other rooms more frequently, I would consider placing one of these heaters in each room and completely turning off the gas-fired furnace.

I also bought this high-efficiency space heater for a friend who lives in a tiny home, and he absolutely loves it. I chose this over a standard coil heater due to several reasons. Firstly, oil furnaces are much safer than electric coil heaters, especially in homes with pets. You can even toss a wet coat over it, and it will be dry in no time without any risk of fire or scorching. Additionally, it operates silently, unlike coil space heaters that can be noisy and power-wasting.

While it may take slightly longer to heat up a cold room compared to a standard coil heater or propane heater, the lower cost of operation makes it worthwhile. My friend appreciates the convenience of the remote control, allowing him to adjust the temperature without getting out of bed in the middle of the night. Overall, this radiator heater is highly recommended for its safety, quiet operation, ease of use, and energy efficiency.

Lastly, I purchased this portable heater for my older apartment, which only has a pilot light heater. The gas bill in the winter was skyrocketing, so I decided to invest in a portable heater to save on costs. Initially, I was skeptical about its warmth due to its compact size, but after using it for over a month, I can confidently say that it provides sufficient heat. We usually set it to 80-86F at night, and it keeps our bedroom warm throughout the night. Our puppy loves sleeping beside it, and it's absolutely adorable. Additionally, it works great to keep your feet warm if you place it near your chair while working on the computer. Overall, I am pleased with this portable heater and would recommend it for its performance and effectiveness.

The heater has a fast heating speed and a constant temperature, making it safe to use without the fear of burns. It is particularly effective in the bathroom, ensuring that winter baths are never cold. However, caution must be exercised with regards to electricity and keeping the heater away from water.

Although not the largest heater, it can effectively heat small spaces and even larger ones if left on for a while. It provides wonderful radiant heat that is enjoyed by small pets, such as dogs. While it doesn't get too hot to use on carpet, it is advisable not to place it close to a wall unless it is made of rock.

Personally, I chose to replace my gas furnace with this heater, and it has been successful in keeping my space warm. However, I would not recommend using it around children due to its potential to cause burns. On the other hand, my four dogs have had no issues avoiding it and have not suffered any burns.

This little floor heater is a great addition to any workspace. It heats up quickly and keeps the user warm and comfortable throughout the day. Additionally, it has a nice appearance, user-friendly controls, and is easy to move around. I highly recommend this oil heater.

One of the standout features of this heater is its silent operation. It works without making any sound, ensuring a quiet environment. The heating is also rapid, making it perfect for keeping warm during the night. Even if my 2-year-old son turns over in his bed, I don't have to worry about him catching a cold, as the heater provides a comfortable level of warmth at 600W. The retractable towel racks are a useful addition. Furthermore, the heat emitted from the front, back, and top of the product does not burn the skin upon touch.

I purchased this heater as a replacement for a traditional one that caused dry air and discomfort. This heater, however, can be adjusted based on the room's temperature and does not cause dry air, making it a more comfortable option.

After reading several reviews and experiencing the product firsthand, I feel compelled to address a particular claim made by another reviewer regarding the thermostat numbering of this heater. It is important to clarify this misinformation, as it can potentially lead to confusion and dissatisfaction among potential buyers.

Contrary to the claim made by the other reviewer, the thermostat numbering of this heater is not counter-intuitive. The numbers on the thermostat are indeed intuitive, with lower numbers corresponding to lower temperature settings and higher numbers corresponding to higher temperature settings. It is crucial to operate the heater based on this understanding to achieve the desired temperature.

I understand how the quirky behavior of the LED indicator, particularly at the "MIN" power level, can be misleading. It may give the impression that the thermostat is numbered backwards. However, through thorough testing with a measuring device, I have discovered that this is not the case. The LED indicator's behavior at the "MIN" power level is anomalous and does not accurately reflect the heater's operation. It may suggest increasing or decreasing heater operation when, in fact, the opposite is occurring.

To simplify, here are the guidelines for adjusting the thermostat:

– If you find the maintained temperature too hot, lower the thermostat to a lower number.

– If you find the maintained temperature too cold, increase the thermostat to a higher number.

It is crucial to ignore the LED indicator's behavior at the "MIN" power setting, as it does not accurately represent the heater's heating operation.

The Costway 1500W oil radiator heater is a great addition to any home, providing efficient and reliable heat. The heater is shipped in a solid box and requires minimal assembly, mainly attaching the caster wheels. Within minutes, you'll have the radiator ready to use.

While the radiator is smaller than expected, it is heavy and solid, ensuring durability. The caster wheels make it easy to move the heater around the house as needed. The turn knobs for turning on/off and controlling the heat level are conveniently located at one end of the radiator. Simply turn on the heater with one knob and adjust the heat level with another.

I have personally been using this oil radiator heater in a 200sq ft room, and it has exceeded my expectations. I typically use it at the highest heat setting, and overnight it gradually warms up the room. By morning, the temperature in the room is 3-4°F higher than outside, even with the door open. I can only imagine that the temperature would be even higher if the door was closed.

I have been using this oil radiator heater almost every night for two months to keep the temperature comfortable while sleeping, and it has worked exceptionally well. Not only does it provide the desired warmth, but it also helps save on energy bills by avoiding the use of the central furnace throughout the night.

Another reviewer mentioned that the heater works as advertised and they have been using it for a few weeks. They prefer it over their ceramic heater, thanks to the three power level adjustments and an additional knob for further temperature control. They also suggest using a smart outlet for added convenience.

However, it's important to note that there is no safety cage around the fins of the device. This could be a concern for those with curious pets or children. While the fins are warm to the touch and won't burn you, the top and bottom oil reservoirs do get quite hot.

Lastly, another user mentioned using the heater to maintain temperature for their plants in a three-season porch. Even with temperatures as low as 10°F below 0° outside, the heater has successfully maintained the room around 60-65°F, which is ideal for plants.

I recently purchased the heater from Amazon and wanted to share my thoughts on it. Firstly, I have to mention that the room size description on the listing is incorrect. It claims to be suitable for a 250 sq ft area, but according to the manufacturer's specs, it is actually suitable for a 144 sq ft area. This means that it is a 5000 BTU heater, perfect for small to medium-sized rooms, around 15×20 ft in size.

One important thing to note is that this heater pulls about 12.5 AMPS on high, which is equivalent to 1500 Watts. This means that if you are using it with an extension cord, you need to be cautious as it can potentially overload your electrical outlet and even cause it to burn. It is recommended to not use an extension cord, but if you must, make sure it is no longer than 10 ft and has a capacity of at least 15 AMP (10 Gauge). Also, be mindful of not plugging multiple appliances into the same outlet as the heater, as it can lead to an overload.

In terms of performance, I have been running this heater on high for the past couple of days and have not experienced any issues with odor or unusual sounds. I do hear a faint clicking sound when the thermostat turns on and off, but it is barely noticeable, even for my super light sleeper wife. I believe that the loud cracking/popping sound that some people have complained about might be due to poor assembly of the panels or poorly manufactured and treated metal components. These components may be expanding and contracting during heat-up and cool-down cycles, resulting in the annoying sounds. However, a properly assembled heater should run quietly, with only slight popping or crackling during cold start that should diminish once fully warmed up.

Now, onto the positive aspects of this heater. I must say that it has been fantastic for us. We live in a 100-year-old building that is quite drafty, and this Winter has been particularly challenging in terms of staying comfortably warm. In addition to the usual routine of putting up cold weather curtains and sealing our windows, we decided to add this heater, and it has exceeded our expectations. Despite its small size, it puts out a significant amount of heat and really helps in keeping our room warm.

I cannot comment yet on how our electric bill will be affected, as we have only been using it for a short while. However, it's worth noting that it does dry the air when set on high, which is expected. To counteract this, we run a humidifier to maintain a comfortable level of humidity in the room.

The heater I purchased met all my expectations and delivered exactly what I needed. It is a no-frills, straightforward device that effectively heats up my poorly insulated bathroom and kitchen area. I appreciate that it doesn't dry out the air, which is already a problem during the winter months. Its simplicity is a positive aspect for me as it ensures durability and longevity.

I am extremely satisfied with this oil burner as it provides consistent and even heat. It surpasses the heating capacity of the store's system, making it a perfect addition to my home.

I purchased this heater in preparation for the upcoming winter, as I will have a newborn and my mother-in-law expressed concerns about our existing heater system. There have been instances where our air conditioner stopped working, and it was a hassle to find a handyman to fix it, leaving us without heating for a week. This heater has given us peace of mind, ensuring that my baby remains warm even if our primary system fails. It also performs exceptionally well in the bathroom, making it suitable for bathing the baby during the winter months. Overall, it is a reliable and effective product that I would highly recommend.

The unit performs well and meets my expectations. I purchased two heaters for my contract work away from home, where I only need to heat specific rooms. The heaters are effective in heating my 20×20 bedroom and 15×12 bathroom.

I would like to address some misconceptions and provide a clear understanding of the product. Firstly, there is an initial odor during the curing process and burning off of any coatings or films. While some may claim there is no odor, it is important to recognize that individual senses vary. Trusting those who can detect the odor can provide valuable insight. It is advisable to wipe down the unit carefully to potentially reduce this period of off-gassing.

In terms of heat output, it is important to understand the laws of physics. Power is power, and wattage is consistent across different heaters. Therefore, a 1500w ceramic heater and a 1500w oil radiator will generate the same amount of heat transfer. The difference lies in the direction of heat dispersion, noise levels, and cycling temperature swings. The oil and fins in the radiator help diffuse the direction of heat and minimize temperature fluctuations during cycling. However, the overall heat transfer into a sealed room remains the same for any heater with the same power consumption.

It is crucial to note that heaters are consistent in behavior for a given power consumption. While there may be minor inefficiencies, the heat produced by the unit itself is consistent. Unlike air conditioners, where inefficiencies lead to counterproductive heat, this oil-filled heater operates efficiently in transferring heat into a sealed room.
