10 Best Oil Filled Space Heater 2026 in the United States

The PELONIS Oil Filled Radiator Heater is a strong choice for heating large rooms up to around 280 square feet. Its 1500W heating power combined with upgraded M-shaped fins helps spread warmth efficiently and quickly, creating a cozy environment without drying out the air. The heater offers three power settings (600W, 900W, and 1500W) and an adjustable thermostat that lets you set the temperature in small steps from 41°F to 95°F, allowing for precise comfort control.

One of its standout features is the very quiet operation since it has no fan, producing almost zero noise, which is ideal for bedrooms, home offices, or any quiet space. It also includes useful energy-saving ECO mode to reduce electricity use, potentially lowering your heating bills. Safety is well covered with overheat and tip-over protection, giving peace of mind if you have kids or pets around.

Portability is decent given its size; the heater weighs about 24 pounds and has wheels plus handles to move it easily between rooms. The 24-hour timer and remote control add convenience, letting you control the heater from across the room or schedule heating to match your daily routine. It is a bit tall (about 26 inches) but slim enough to fit in common indoor spaces without taking up too much floor space. Designed for indoor use only and best suited for bedrooms and offices, heavier or larger spaces might require additional heating sources. This PELONIS heater combines strong heating performance, quiet operation, good safety features, and energy efficiency, making it a solid pick for anyone needing reliable indoor warmth with easy-to-use controls. Just keep in mind its weight and size if you’re looking for something ultra-compact or lightweight.

The Amazon Basics Oil Space Heater is a solid choice for heating small to medium indoor spaces, like rooms up to about 150 square feet. It offers three heat settings — high (1500W), medium (900W), and low (600W) — which lets you adjust the warmth to your preference using a simple manual thermostat control. The oil-filled design with seven fins means it keeps heat longer and spreads it evenly, providing cozy warmth without needing constant power. This also helps save energy since the heater continues radiating heat after it’s turned off.

Safety is well considered, with tip-over and overheat protection plus ETL certification, so you can feel secure using it around the home. The heater is fairly portable thanks to caster wheels and a handle, although it weighs around 15 pounds, meaning it’s easy to move but not super lightweight. It runs silently because it has no fan, making it great for bedrooms or offices where noise can be disruptive. Assembly is required, but it’s generally straightforward with no special maintenance needed since the oil is sealed inside.

The maximum temperature setting is about 90°F, which is comfortable but not extremely hot. For those seeking a quiet, energy-efficient, easy-to-use heater that offers steady warmth and basic safety features, this Amazon Basics model is a dependable option. However, if you need to heat a larger area or want more advanced controls, you might need to look elsewhere.

The Pelonis Champagne Oil Filled Radiator Heater is a solid choice for anyone looking to heat a medium to large indoor room efficiently and quietly. With 1500 watts of heating power and three adjustable heat settings, it can quickly warm up spaces up to about 164 square feet. The built-in thermostat and five temperature settings let you personalize the warmth between 65°F and 85°F, helping to keep your room comfortable without wasting electricity. An ECO mode automatically adjusts heating to save energy, making it friendlier to your utility bills during colder months. Safety is well covered with tip-over protection, overheat shutoff, and flame-retardant materials, which are important features for peace of mind, especially in homes with kids or pets. The heater is also portable, featuring caster wheels and a handle, so you can easily move it from room to room. The remote control and digital display add convenience, allowing you to adjust settings without getting up.

One of the biggest advantages is its quiet operation, ideal for bedrooms or offices where low noise is preferred since it doesn’t use a fan. On the downside, although it’s portable, it’s somewhat heavy at about 16 pounds, which might be a bit cumbersome for some users. Also, while it’s energy efficient compared to some heaters, oil-filled radiators typically take longer to heat a room than fan heaters, so it’s better for steady, longer-term warmth rather than quick bursts of heat. This heater is well suited for those who want a safe, quiet, and energy-conscious option to keep indoor spaces cozy through the winter.
