9 Best Delonghi Electric Heaters 2025 in the United States

The De'Longhi Dragon Digital Oil Filled Radiator Heater is a solid choice for indoor heating, especially in small to medium-sized rooms. With 1500 watts of heating power, it provides effective warmth while the digital control panel with LED display makes it easy to operate. The programmable 24-hour timer adds convenience by allowing you to set your heating schedule in advance. One of its standout features is the 75% more radiant surface area compared to similar models, which enhances heat distribution and quickens the warm-up process.

Additionally, the heater is designed to create a better breathing environment by minimizing dry air and not using a fan, making it more allergy-friendly. Safety features such as a child lock, thermal cut-off function, and anti-freeze setting offer peace of mind during use. The built-in ECO Plus function optimizes energy consumption, which can help save on electricity bills. Portability is another plus, with ergonomic handles and smart snap wheels that require no installation, allowing for easy movement between rooms.

However, being an oil-filled radiator, it may take longer to reach the desired temperature compared to other heater types like ceramic or infrared heaters. Additionally, while it operates quietly, it may not be the best choice for very large spaces or outdoor use. Its maintenance is low, thanks to the durable steel assembly and permanently-sealed oil reservoir. For someone looking for a reliable, energy-efficient indoor heater with strong safety features and easy portability, this De'Longhi model is definitely worth considering.

The De'Longhi Oil-filled Radiator Heater is a 1500W electric space heater designed for indoor use in small to medium-sized rooms such as bedrooms and home offices. One of its key strengths is its ComfortTemp feature, which helps it achieve up to 20% more energy efficiency by automatically maintaining optimal temperature and power levels. The heater is also designed to deliver gentle, quiet heat without stirring up dust and allergens, making it suitable for individuals with allergies.

The exclusive thermal slot design enhances heat flow while keeping the surface temperature low, boosting both safety and heating effectiveness. Additionally, the device includes built-in safety features such as a thermal cut-off and an anti-freeze setting for added peace of mind. Portability is another highlight, with integrated handles and smart snap wheels making it easy to move between rooms. However, at 23.2 pounds, it may still be considered somewhat heavy for frequent relocation.

The control panel is user-friendly, allowing for easy adjustment of the power level and temperature. The heater operates quietly, making it suitable for use in environments where noise can be a distraction. On the downside, its heating coverage is limited to small to medium spaces, so it may not be effective for larger areas. Additionally, while the product is durable and low maintenance, the oil reservoir is permanently sealed, meaning it can't be refilled if issues arise. Despite these minor drawbacks, the De'Longhi Oil-filled Radiator Heater offers a reliable and energy-efficient heating solution, especially for those looking for quiet operation and enhanced safety features.

The De'Longhi Dragon Oil Filled Radiator Heater is a 1500W electric heater designed for indoor use, particularly in small to medium-sized spaces like living rooms and bedrooms. One of its standout features is its 75% larger radiant surface area compared to other models, which helps in distributing heat more efficiently. It also warms up quickly due to its increased convection heating effect and specialized battery design, making it ideal for those looking for fast relief from cold temperatures.

The heater is also allergy-friendly as it doesn't have a fan that stirs up dust or pollen, creating a better breathing environment. With its programmable 24-hour timer and easy-to-use control panel, you can set your desired temperature and power levels conveniently. The ECO Plus feature is a notable addition, optimizing energy consumption by regulating power flow and temperature, thus offering better energy efficiency. Portability is another strong point, thanks to its integrated ergonomic handles and rubber-coated wheels which allow for smooth movement across different surfaces.

The built-in safety features, including child lock, tip-over switch, and thermal cut-off function, provide peace of mind during use, and the anti-freeze setting ensures the heater turns on automatically if temperatures drop below 41°F. However, the radiator is relatively heavy at 25 pounds, which might be cumbersome for some users to move frequently. Additionally, it is designed for floor mounting only, which could limit placement options. Despite these minor drawbacks, this heater is durable with its high-quality steel assembly and low-maintenance design, as the oil reservoir never needs refilling due to its permanent seal. If you're looking for a reliable, efficient, and safe space heater for a small to medium space, the De'Longhi Dragon Oil Filled Radiator Heater could be a great choice.
