10 Best Low Wattage Heaters 2025 in the United States

The Amazon Basics Ceramic Space Heater is a compact and portable option ideal for small spaces like desks and tables. Its small size (5.8"D x 3.4"W x 6"H) and lightweight design (1.4 lbs) make it easy to move around your home or office. With a 500W ceramic heating element, this heater provides quick and efficient warmth, making it a convenient choice for immediate heat needs.

One of its key strengths is its built-in safety feature: the heater has Tip-Over Protection, which means it will automatically shut off if knocked over, adding an extra layer of safety. In terms of noise, being a small heater, it operates relatively quietly, making it suitable for office environments or quiet spaces. However, there are some limitations. With only 500W power, it is not suitable for heating larger areas and is best used for personal space heating. Also, it lacks a thermostat, which means you cannot set a specific temperature, so it might require manual monitoring to maintain comfort.

Its black, rectangular design is simple and unobtrusive, blending well with most decor but does not offer much in terms of aesthetic appeal. Despite these drawbacks, it is a popular and reliable choice for those needing a quick, portable heating solution for small spaces.

The Amazon Basics Ceramic Space Heater is a compact and lightweight option designed for heating small rooms up to about 108 square feet. Its 520-watt ceramic heating element warms up quickly and provides steady heat, which is good for creating cozy comfort in personal spaces like bedrooms or offices. The heater offers three heat settings, allowing you to adjust the warmth to your liking without complicated controls. It features a cool-to-touch black plastic housing, which adds a layer of safety during use.

Weighing just 1.7 pounds and measuring about 7 inches tall, this heater is highly portable and easy to move around or place on a table or the floor. Ceramic heaters are generally quiet, making this model suitable for bedrooms. The small size means it won't take up much space, but it also limits the heating range, so it’s best for individual use rather than warming large areas.

If you need a simple, no-fuss heater for personal comfort and portability, this model fits well. It is best suited for smaller spaces and basic heating needs without advanced controls or extensive safety features.

The De'Longhi Oil Filled Radiator Heater, with a power rating of 1500W, is designed to provide efficient and gentle heating for small to medium-sized indoor spaces like bedrooms and home offices. One of its notable strengths is the ComfortTemp feature, which enhances energy efficiency by maintaining optimal temperature and power levels, potentially saving on energy bills. The exclusive thermal slot design ensures effective heat distribution while keeping the surface temperature low, making it safer to touch.

The heater produces gentle warmth without a fan, which helps maintain better air quality by not stirring up dust and allergens—ideal for those with allergies. Its user-friendly controls and integrated handle make it easy to operate and move around, adding to its portability. Safety is a priority with built-in elements such as thermal cut-off, enclosed heating elements, and an anti-freeze setting that activates when temperatures drop below 41°F.

The durable design with a sealed oil reservoir means minimal maintenance. However, the heater's relatively heavy weight of 23.2 pounds might make frequent relocation a bit challenging for some users. Also, while it is generally quiet, those needing absolute silence may still notice a slight hum. It's a solid choice for those needing reliable, energy-efficient heating with strong safety features.
