Oil fueled space heaters are actually very efficient, cost-effective, and easy to use. The oil is sealed in a section of the space heater and it does not need to be replenished by the user because, unlike propane or kerosene, it is not consumed during the process of producing heat. Instead, the oil is heated when energy is transferred from an internal heating element. The heated oil remains hot for a long time and radiates the warmth out into the room. Since the hot oil radiates the heat, the internal element automatically shuts off. It remains off until the oil cools enough that it no longer produces an adequate amount of heat and then it comes back on and starts the process over again.
The oil space heater is very efficient because it can continue to produce heat even after the internal heating element is no longer consuming energy to heat the oil. It is also more efficient than other types of space heaters because it continually reuses the same amount of oil that was came with the space heater when it was bought. There is never a need to go to a store or dealer to purchase more fuel constantly like there is with space heaters that burn up the propane or kerosene that powers them.
The oil space heaters are also much quieter than other types of space heaters because they usually do not have a built in fan that blows the heated air into the surrounding area. Instead the heat radiates outward from the heated oil in the sealed container within the space heater. The absence of a fan actually adds to the efficiency of the oil space heaters. By not having a fan like some other types of space heaters, there is less energy used by the oil powered space heaters. That can add up to a lot of savings which is why the oil space heaters are so cost-effective.
The oil space heaters are also safer to use than propane or kerosene space heaters because the oil is never burned and therefore does not emit any carbon monoxide into the air and there is no oxygen depletion, either. This aspect alone inspires people to purchase an oil space heater over some of the other types of space heaters because safety of the family and the home is always a major concern. On the subject of safety, oil space heaters are usually equipped with an automatic shut off switch that stops it from working if the space heater is knocked over. In combination with that, with the heating element sealed within the housing, there is less chance of anyone suffering burns when it is accidentally touched. There are many people that will use a oil powered space heater in the room with young children.
Overall, oil space heaters are some of the best space heaters on the market. They are definitely worth the initial cost of the purchase price and will easily pay for themselves in a short amount of time.
