Dr. Heater uses infrared heating, which heats objects in the room, instantly making you feel comfortably warm. By heating only the objects in the space--not the air--Dr. Heater provides maximum warmth and energy efficiency. With its state-of-the-art technology that helps the room retain air moisture, Dr. Heater do not dry out your skin like those convection heaters that blast out hot air, stripping the room of moisture. And the best part? It will save you money. Use Dr. Heater instead of your regular heating system, and you could save up to 50% on your next electricity bill. Plus, with its tip-over protection and auto shut-off overheat protection, you can sleep soundly knowing you have got a heater that is superior in safety. Tests Show Dr. Heater heats Faster and Better than Competing Heaters. In a side-by-side test comparison in airtight chambers with the same starting temperature, Dr. Heater heated the same amount of space much faster than a competing heater that has a price tag more than double that of Dr. Heater. Dr. Heater Delivers 60% more heat than other 1500-watt heaters. No magic trick--we just understand heat transfer better. Just because two heaters have the same wattage does not mean they transfer the same amount of heat. Wattage indicates the amount of electricity needed to power the heater--not the amount of heat it can deliver. Heater is the first to feature a dual heating system for maximum heat transfer rate. It combines the energy efficiency of infrared heat with the comfort of convection heat to heat your room fast and comfortably--without hot spots and cold spots. Dr. Heater uses a state-of-the-art 7-inch blower that generates higher pressure and moves larger air volume at a lower speed, without any of the noise of those other heaters on the market. Dr. Infrared Heater has three power Settings: Auto, Low 1000W and High 1500W. The auto energy saving mode allows you to set your desired temperature from 50-86F. It smartly selects between the two settings depending on your room temperature. The thermostat regulates the heater and causes it to cycle on and off to maintain the set temperature. You can also manually set the heater to run on High or Low all the time or with a timer. The heater has to be turned on first in order to use the remote. This a safety provision mandated by the Underwriters Laboratory. So, in order to use the remote, the first step for the user is to press the POWER button on the heater itself. This turns the heater on STANDBY. Then, pressing the POWER button on the remote will turn the heater on. The heater can't be turned on if the unit is not on STANDBY.
