DeLonghi TRV0715T Vento Hi Speed Convection Oil Filled Radiator Effectively heat any room of the house with this portable convection heater. The unit features vertical metal fins shaped similarly to an old fashioned radiator, and its heating element has been submerged in pure diathermic oil which remains permanently sealed in the fins. The heating element heats the oil causing the radiator and the air surrounding it to become warm. Choose from three variable heat settings minimum, medium, and maximum. When the room reaches a comfortable temperature, turn the thermostat knob until it clicks, the unit will maintain the set temperature and conserve energy by cycling on and off. For added energy conservation, its 24 hour programmable timer offers 96 settings that make it simple to heat a room for any desired amount of time and for different time periods throughout the day and night. Another thoughtful detail includes its anti freeze setting which allows the unit to automatically turn itself on when the temperature drops below 44 degrees F. The heater also provides room monitoring thermostat cord storage, and patented smart snap wheels that require no assembly, simply snap into place. Safety features include durable metal construction, no exposed elements and automatic shut off in case of accidental overheating.
