Best Room Heaters 2019
Classification Of Room Heaters
Infrared Type Room Heaters
Infrared type of air Heaters directly heat the objects without using or heating air, the same way as the sun does. The objects would absorb the energy released by Infrared rays and reflect the energy to the surroundings. This process continues until an equilibrium level or consistent temperature is achieved. Since heat is absorbed by the objects directly without loss of energy, infrared heaters are more energy efficient. Infrared Heaters are normally installed on the ceiling so that the rays coming out of heaters directly reach the floor & get absorbed by it. After reflection from the floor, heat moves upward as hot air is lighter than cold air. Since all the objects lying in the room would receive the infrared rays and reflect them, the whole room becomes warm very easily. If Room Heater of proper size has been selected, It won't take more than 10 to 15 minutes to warm up the room.
Convection (Blower / Fan) Type Room Heaters
The Bowler or Fan type convectors have a metallic element which quickly heats up. The air discharged by the blower and coming in contact with the element, become hot. The warm air then circulates through the grill of the convector. Hot air being lighter would move upward and cool air will come down to take its place. This loop of air circulation will continue. Since objects do not become hot directly, there may be a temperature difference between them. As hot air rises up, the temperature near the floor will be less. The low temperature near the floor causes an unpleasant feeling known as "Cold-Leg". Due to this, people would often increase the temperature setting of the heater and which in turn would lead to more electricity consumption and an increase in electricity bills.
Oil Filled Room Heaters
In oil-filled Heaters, an electric element is submerged inside the oil. Heat is transferred from the hot element to Oil. Oil molecules closer to heating element receive the heat energy and transfer it to the next layer of molecules by convection currents. The warm oil then moves upward and cool oil will come in contact with the hot element. The cycle will continue until the oil in the reservoir or fins become hot. This heat energy is then transferred to the body of shell or fins. The fins would transfer the heat energy to the air coming in touch and the same convection cycle will start. Oil-filled Room Heater work on mixed convection, conduction, and radiation principle - Convection inside, Conduction in reservoir /fins wall and convection and radiation outside. This mix of radiation and convection eliminates the possibility of dry air due to which OFR are health-friendly but they take a little more time to warm the room.
Room Heater Wattage Size Calculation
I will share with you the thumb rule for calculating the heater size for your room based on room square feet. I am considering the room ceiling at 8 feet. To calculate the wattage, you can follow the following steps
- Measure the length and width of the room. Multiply them to get the square feet. A 12 feet long and 12 feet wide room have 144 square feet area.
- Take into consideration the insulation of your room
- Very good insulation correspond to consumption of 7.5 KW per square foot.
- Average insulation corresponds to the consumption of 10 KW per square foot
- Poor insulation corresponds to the consumption of 12.5 KW per square foot
- For calculation purpose, I will use the average insulation supposing room to be not very old. Therefore multiply 144 square foot with 10 i.e 1440 Watt.
- You can make slight adjustments if the ceiling is more than 8 feet by adding 25% for every 2 feet increase. Therefore if the room has a ceiling above 8 feet and up to 10 feet you need to add 25% of 1440 watt which will make it 1800 watt.
Against the misconception, you are not required to change the oil in the oil room heater as the oil is only being used to convey the heat and is not consumed.

Dr Infrared Heater Portable Space Heater, 1500-Watt
It is one of the best and highly recommended. The Dr Infrared Heater also consumes 1500 W of maximum energy like other Heaters but comparison ends here. Two heaters with same wattage does not mean that they will produce the same amount of Heat.
Dr Infrared heater are upto 60% more efficient than many other branded Heaters available in the market.
The reason behind the efficiency is better understanding of Heat Transfer. The Dr Infrared Portable Space Heater incorporate Advance Dual Heating System with a combination of PTC and Quartz Infrared Element for a better heat distribution.
Dr Infrared Heater have three temperature settings i.e Low, High and Auto. When it is set kin Auto mode , the heater keeps on switching automatically between High and Low range to maintain the desired temperature.
The benefit of Infrared rays is that they heat the objects in the room and just not only the air which provide the instant comfort to you. Since the infrared rays heats the object directly, the air in the room would retain its moisture and your skin would not dry out.
- Three Power Settings 1000/1500 Watt/ Auto
- Auto thermal cut-off feature.
- Infrared rays to heat the object.
- Convection current in air eliminate hot and cold spots in the room.
- Auto Energy Saving Mode.
