The De'Longhi Oil filled Radiator Heater is designed for indoor use, specifically for rooms like bedrooms and home offices. With a heating capacity of 1500 watts, it effectively warms small to medium-sized spaces. Being an oil-filled radiator type, it provides gentle and consistent heat, which helps maintain a comfortable environment without the noise or air dryness associated with fan-based heaters.

The heater is energy-efficient, especially with its ComfortTemp feature, which helps to maintain optimal temperature and power levels, potentially reducing energy usage by up to 20%. Safety is a strong point, with built-in elements like thermal cut-off, fully enclosed heating elements, and an anti-freeze setting that activates below 41 degrees Fahrenheit. Its quiet operation is ideal for environments where noise could be a distraction, such as offices or bedrooms.

Portability is facilitated by integrated handles and smart snap wheels, allowing easy movement between rooms without installation. Additionally, simple controls make it user-friendly to adjust power levels and temperature settings. However, its weight of 23.4 pounds might make it less convenient for frequent relocation, and the heater's size could be cumbersome in very small spaces. This heater is suited for users seeking a quiet, efficient, and safe heating solution for moderately sized rooms.

The digital control panel with an LED display and a 24-hour programmable timer enhances user convenience, allowing precise control over heating schedules.

This heater can be freestanding or wall-mounted, offering flexibility in placement. It's lightweight and portable with an integrated carrying handle, making it easy to move between rooms as needed.

The heater's energy efficiency is enhanced by the ECO PLUS function, which adjusts heat settings to conserve energy. Safety features include a thermal shutoff to prevent overheating and a tip-over switch that turns the unit off if it falls over, providing peace of mind during use. Additionally, the heater has an anti-freeze setting to help prevent frozen pipes in extremely cold conditions, making it suitable for basements or vacation homes.

Control options are user-friendly, with digital controls, an adjustable thermostat, a delayed on/off 24-hour timer, and multiple heat settings for personalized comfort.

Despite these minor drawbacks, the DeLonghi Convection Panel Heater is a reliable and convenient heater for various indoor settings.
