Efficient and Economical Room Heating The Comfort Zone Electric Oil-Filled Radiator Heater is a great way to save money on your heating bills. By lowering the overall temperature of your home or office and simply using this heater to keep the room you are currently occupying comfortable, you can cut your energy usage significantly. The oil radiator heater's five-channel design is permanently sealed, and there is no need to worry about refilling it. Silent Operation The electric radiator heater operates silently to minimize disruptions. This makes it quiet enough to leave running even while you're on the phone, studying or trying to drift off to sleep at night. Practical Settings Three convenient heat settings and an adjustable thermostat make it easy to control the unit's output. Simply turn the knobs at the top of the radiator heater to quickly adjust its temperature. Advanced Safety Features A tip-over switch automatically turns the heater off if it is knocked over to help prevent fires, while a built-in sensor helps to prevent the unit from overheating. A molded handle makes it easy to transport, and it stays cool while the unit is in use to help prevent burned fingers when you move it between locations. Compact and Portable Design The Comfort Zone Radiator Heater's compact design allows it to fit into a wide variety of medium-sized spaces with ease. It comes equipped with convenient built-in cord storage and casters that swivel smoothly in any direction to allow you to quickly roll the heater from one room to another.
