  • Types of Heaters


With the exception of heat pumps, all electric heaters are equally efficient. They convert all the electricity they consume into useful heat - so don't believe claims that any one type of electric heater is more efficient than the other. Having said that, choosing the right type of heater for the situation is important to get the full benefit of all of the heat you're paying for.


An oil heater, also known as an oil-filled heater, oil-filled radiator, or column heater, is a common form of convection heater used in domestic heating.

Although filled with oil, it is electrically heated and does not involve burning any oil fuel; the oil is used as a heat reservoir (buffer), not as a fuel.


Oil heaters consist of metal columns with cavities inside which a heat transfer oil flows freely around the heater. A heating element at the base of the heater heats up the oil, which then flows around the cavities of the heater by convection. The oil has a relatively high specific heat capacity and high boiling point.

The high specific heat capacity allows the oil to effectively transfer thermal energy from the heating element, while the oil's high boiling point allows it to remain in the liquid phase for the purpose of heating, so that the heater does not have to be a high pressure vessel.


  • Oil filled room heaters consume less electricity. They are good for power saving. As oil is used as heat reservoir, even you switch off the heater still room will be hot.
  • Oil filled room heaters neither burn oxygen nor reduce humidity making the best choice for new born babies. In this regard they are healthy options as it won't cause any suffocation or dry eyes, skin rashes.
  • Oil filled room heaters best fit for large room and all night usage as well
  • Oil filled room heaters are less noisy, quiet. You don't even feel the presence of it in the room.
  • Oil filled room heaters child safe as their surface won't heat up much. You don't need to place them closer to the bed. Simply put the Oil filled room heaters in the corner of room.


A ceramic heater as a consumer product is a space heater that generates heat using a heating element of PTC (Positive Temperature Coefficient) ceramic.

Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters


There is a difference between ceramic heaters and other types of heaters; this is because ceramic heaters heat up the Environment more easily. Unlike coil heaters, they do not use fire and have no risks of burning. On the other hand, coil heaters work by an electric current which heats them to such a high temperature that they burn.

Ceramic heaters have a number of ceramic plates attached to some coils of metal that heat up in the same way as a coil heater, but the plates absorb the heat and release it into the air.

They are quicker than coil heaters and they take less time to cool down once they are switched off.


  • Advantage of this device is that it can be used for larger areas and are more efficient than radiant heaters in this task. If you want to use a ceramic heater for a larger area, then you have to opt for models with fan. Models without fan are more appropriate for small areas.
  • Advantages of ceramic heaters include their safety features too. It has been observed that the overall temperature of the equipment as well as its hottest part is very low, as compared to other space heaters. Most of the models have in-built mechanisms to reduce the flow of electric charge as the temperature hits 380 degrees Fahrenheit. This feature Considerably reduces the risk of fire.
  • The cost of use of this heater is much lower than other conventional home heating systems, as you have to use it for small areas, as compared to central heating. It is also claimed by the manufacturers that these heaters do not use much electricity, as compared to other types. They heat up quickly and so, are considered as more energy-efficient. It has also been suggested by energy experts that the efficiency of ceramic heaters can be further enhanced by properly insulating the house.
  • Most of these heaters come up with many built-in safety features like timer, touch sensor, and overheat sensor, thermostat, manual heat adjustment, fan speed adjustment, digital display and remote control, making it more advantageous.


Quartz heating is a type of radiant heating, commonly referred to as short wave infrared heating. Radiant heating uses infrared waves to directly heat the surfaces of objects.

All objects emit and absorb infrared heat, which is part of the electromagnetic spectrum with a frequency below visible light. Hotter objects will radiate more of this heat. This is the basis of the technology for most quartz heaters.


The principle of quartz heating (a type of radiant heating) is Well-known and has been in use for many years. Electric infrared energy travels in straight lines from the heat source. This energy is directed into specific patterns by optically designed reflectors. Infrared, like light, travels outward from the heat source and diffuses over a distance.

Quartz heating works similar to the sun, travelling in parallel Lines, even able to pass through the vacuum of space. This is why quartz heating is not affected by wind and able to directly heat people and objects.

Quartz heaters are suitable for outdoor heating as well as indoor heating and due to their heat intensity, are also highly effective for space heating.


  • The quartz infrared rays heat the objects or people directly. They do not circulate the warm air unlike traditional heaters, which heat the air in the room first. They provide steady heat from ceiling to floor evenly and consistently from the location they are placed.
  • Quartz infrared heaters are affordable and their cost of installation is lower than the other sources of heating. Cost of maintenance is also low. For example bulbs used in these heaters last for 3 to 5 years and their cost ranges is low. These heaters require less quartz bulb replacements too.
  • The quartz electrical heaters are more energy efficient as they heat the objects directly and thus take less time and consume less energy for heating the room. Most of the heaters will turn off once enough heat is provided, thus they reduce the electricity costs.
  • The quartz infrared heaters are durable and they can last for many years. Even the maintenance required for this type of heaters is less. The bulbs in these heaters are made up of a high quality quartz sheath in which the tungsten filament is placed, making them last up to 5000 to 7000 hours.
