DeLonghi TRD0715T Safeheat Oil Filled Radiator The DeLonghi TRD0715T Safeheat Oil Filled Radiator is constructed rustproof metal for even heat distribution and resilience with pure diathermic oil completely sealed inside. Heat radiates through several vertical thermal tunnels while keeping the hot elements enclosed and out of the reach of fingers, and other body parts and objects. Three power settings allow flexibility for diverse rooms and personal heating needs. For energy efficiency, the heater runs low at 600 watts or medium at 900 watts to slowly spread warmth. On high at 1500 watts, the radiator brings full heat to the room with extra speed. Users direct the room's temperature for comfort with an adjustable thermostat. With the 24 hour programmable timer the heater offers, 96 options in terms of temperature, wattage, duration, and activation time. An antifreeze function engages should the indoor temperature fall below 44 degrees F, while the heater also automatically shuts off upon knock over or overheating. Four wheels enable easy transportation from one room to another.
