Heating Power (Wattage)
This simple radiant heater runs well for months at a time, keeping spaces warm even with a stiff north wind blowing.
Safety Features
The handle design could be improved, as it gets very warm and can be uncomfortable to use without protection.
Noise Level
The heater is very quiet, with only a faint click when it comes on, which you have to be listening for.
Size and Design
The on/off light is very bright and can be distracting in a bedroom setting, but a piece of electrical tape can solve this issue.

The Amazon Basics Oil Heater is a solid choice for indoor heating with a powerful 1500W capacity. It offers three adjustable heat settings (High, Medium, and Low) allowing you to tailor the warmth to your comfort level. This heater uses oil-filled fins, which provide consistent and long-lasting heat, making it energy-efficient and perfect for rooms up to 144 sq ft. One of its standout features is its quiet operation, making it ideal for use in bedrooms and offices without any distracting fan noise.

Safety is well-addressed with ETL certification, including tip-over and overheat protection, automatically shutting off the heater to prevent accidents. This makes it a worry-free option for households, especially those with children or pets. The heater’s portability is another plus, featuring smooth-gliding caster wheels and a convenient handle, making it easy to move from room to room. Its slim, vertical design helps it fit into tight spaces without taking up much floor space.

However, it might be slightly heavy at 17.42 pounds, which could be a consideration for some users. Also, while the heater is efficient, it might take a little longer to heat up compared to fan-based heaters. If you need a quiet, safe, and portable heater for a medium-sized room, this product would be a good fit.

The Amazon Basics Oil Space Heater is a solid choice for anyone needing a portable radiator heater. With a power output that can be adjusted to three settings—High (1500W), Medium (900W), and Low (600W)—it offers flexible heating options suitable for small to medium-sized rooms (up to 150 square feet). The adjustable thermostat allows you to maintain a comfortable temperature, while the seven oil-filled fins ensure even heat distribution and retain warmth longer, which can help save on energy costs.

One standout feature is its quiet operation, making it an excellent option for noise-sensitive areas like bedrooms and offices. Additionally, the heater includes essential safety features, such as tip-over and overheat protection, and it has received an ETL safety certification. Portability is another strong point, thanks to its caster wheels and handle, making it easy to move around the house. The design is user-friendly with simple manual controls, and it requires no maintenance, as the oil inside the fins is permanently sealed.

There are some drawbacks to consider. The heater's size and weight (15.41 pounds) might be cumbersome for some users, and it requires assembly, which could be inconvenient. Furthermore, while it is energy efficient, it might not be powerful enough for larger spaces. This heater is best suited for those looking for a reliable, quiet, and portable heating solution for smaller indoor areas.

The De'Longhi Oil Filled Radiator Heater offers reliable 1500W heating power, suitable for warming small to medium rooms such as bedrooms or home offices. Its thermostat control is user-friendly, with simple knobs and a ComfortTemp feature that helps maintain an optimal temperature efficiently, potentially saving up to 20% energy compared to basic models. Safety is well-covered through thermal cut-off, enclosed heating elements, and an anti-freeze setting that automatically activates at low temperatures, making it safer for indoor use.

Portability is a strong point thanks to its integrated handle and smart wheels, despite its somewhat hefty 23-pound weight, allowing easy movement between rooms. The heater runs quietly without a fan, which is ideal for allergy sufferers since it doesn't stir up dust or pollen. Its design is practical and durable, featuring a corrosion-resistant finish and a compact footprint (6.5" deep by 15.5" wide and 27" tall) that fits well in typical living spaces.

The unit is relatively heavy compared to some portable heaters and might take longer to warm a room initially due to oil-filled technology. While energy-efficient for its type, it won't be as quick or flexible as fan heaters for instant heat. If you want a quiet, steady heat source that’s easy to move and built with safety in mind, this De'Longhi model is a solid choice. However, if you prioritize ultra-lightweight or very rapid heating, you might consider other options.

Buying Guide for the Best Portable Radiator Heater

Choosing the right portable radiator heater can make a significant difference in your comfort during the colder months. It's important to consider various specifications to ensure you get a heater that meets your needs efficiently and safely. Here are some key specs to look at and how to navigate them to find the best fit for you.
Heating Power (Wattage)Heating power, measured in watts, determines how much heat the radiator can produce. This is crucial because it affects how quickly and effectively the heater can warm up a space. Generally, heaters range from 400 watts to 1500 watts. For small rooms or personal spaces, a heater with lower wattage (400-800 watts) is sufficient. For medium to large rooms, you might need a heater with higher wattage (1000-1500 watts). Consider the size of the room you want to heat when choosing the wattage.
Thermostat ControlA thermostat control allows you to set and maintain a desired temperature. This feature is important for energy efficiency and comfort, as it prevents the room from becoming too hot or too cold. Some heaters come with adjustable thermostats, while others have fixed settings. If you want precise control over the room temperature, look for a heater with an adjustable thermostat.
Safety FeaturesSafety features are essential to prevent accidents and ensure safe operation. Key safety features include overheat protection, which automatically shuts off the heater if it gets too hot, and tip-over protection, which turns off the heater if it is knocked over. These features are particularly important if you have children or pets. Always prioritize heaters with robust safety features to minimize risks.
PortabilityPortability refers to how easy it is to move the heater from one place to another. This is important if you plan to use the heater in different rooms or need to store it away when not in use. Look for heaters with wheels, handles, or a lightweight design for easy transportation. Consider your mobility needs and how often you will need to move the heater when evaluating portability.
Noise LevelThe noise level of a heater can affect your comfort, especially if you plan to use it in a bedroom or office. Some heaters operate quietly, while others can be quite noisy. If you are sensitive to noise or need a quiet environment, look for heaters that are specifically designed to operate silently or have a low noise level. Check user reviews or product descriptions for information on noise levels.
Energy EfficiencyEnergy efficiency indicates how effectively the heater converts electricity into heat. This is important for keeping your energy bills low and reducing environmental impact. Look for heaters with energy-saving features such as programmable timers, eco-modes, or energy-efficient ratings. If you are concerned about energy consumption, choose a heater with high energy efficiency to save on costs and be more environmentally friendly.
Size and DesignThe size and design of the heater can affect its placement and how well it fits into your space. Compact heaters are ideal for small rooms or areas with limited space, while larger heaters may be more suitable for bigger rooms. Additionally, consider the design and aesthetics of the heater to ensure it complements your home decor. Think about where you will place the heater and how much space you have available when choosing the size and design.
