What Are The Best Oil Filled Heaters in 2017

Are you tired of paying to heat rooms in your home that you don’t use? Are you looking for ways to lower the thermostat without suffering from the cold? Oil filled heaters are an economical option that you can use to help heat your home. Oil filled heaters consume very little electricity, have no exposed heating element, and continue radiating heat long after they are shut off. Here is a look at five of the best oil filled heaters:

Advantages of Oil Filled Heaters.

With all of the styles of heaters currently available it can be difficult to know which style to buy. As with all other heaters, oil filled heaters have certain advantages.

Knowing the advantages of oil filled heaters will allow you to compare them to other heater styles, so you can choose the best one for your needs.

  • Quiet Operation:

One of the biggest advantages of oil filled heaters is that they use no fan. With no fan you won’t have to worry about rattling noises due to oscillation. Traditional space heaters, even if they don’t oscillate, use fans to circulate the hot air so it goes directly into the room. These fans can be noisy, especially if they have blades as they chop up the air. Without the fan or oscillating feature, oil filled heaters are virtually silent. You will only hear a quiet clicking as the thermostat adjusts.

  • Energy Efficient:

Oil filled heaters are 100% efficient. All of the energy used with an oil filled heater is converted into heat, which means you can heat your home without wasting money. Oil filled heaters require no extra energy to run fans or other components. Plus they are slow to cool off, which allows them to heat the room long after they have been shut down.

  • Thermostat Controlled:

One of the greatest things about thermostats is the ability to keep the house or room at your desired temperature. Almost all furnaces are thermostat controlled, but not all room heaters are. Oil filled heaters are thermostat controlled. You set the desired temperature and once the room reaches that temperature the heater will cycle on and off to maintain the temperature. This saves energy and therefore money because the heater is not continuously running. Plus, the rooms will not become overheated.

  • Compact Design:

This style of heater is designed to be used in different areas. To make the unit portable most manufacturers offer a compact, lightweight design. Some will feature a handle for ease of portability; others are small enough to fit underneath a desk.

  • No Need to Refill:

A false assumption about oil filled heaters is they need to be refilled because the oil will run out. The only time you would need to refill the oil is if it was being used as a fuel. Oil filled heaters do not require the oil to be used for fuel, so you won’t have to replace it.

  • Won’t Dry Out The Air:

One of the biggest drawbacks to conventional heating methods, such as forced air and space heaters, is that they dry out the air. Many people add humidifiers to their homes to help keep moisture in the air during the months their furnaces are running. Oil filled heaters will not dry out the air because they simply have no fan. It is the fan that circulates the air in other units that also cause the air to dry out.

Are Oil Filled Heaters Safe?

One of the biggest controversies surrounding any kind of external heater is whether or not they are safe to use. Oil filled heaters are just as safe to use as other personal heaters on the market. In fact, research suggests that they are one of the safest space heaters available. Here are some of the reasons as to why oil filled heaters are safe.

  • Hidden heating element:

With some heaters, you have to worry about the heating element being exposed. With an exposed heating element you run the risk of the heater causing a fore, especially if clearance rates are not properly followed. Oil filled heaters have no exposed heating element; it is literally sealed inside the heater. Being sealed inside means it has no chance of coming into contact with anything flammable.

  • No Fumes:

Oil filled heaters require no gas or oil for fuel. As they don’t burn either of these items for fuel they do not emit gas or fumes making them a safe choice to use indoors.

  • Safe Surfaces:

Most oil filled heaters have metal surfaces. These surfaces will become warm to the touch when the heater is in use and for a period of time after it has been shut off. Although the surface will get warm it will never get hot enough to burn you or anything that brushes against it.

  • No Grilles:

One of the biggest downfalls to some heaters is the grilles or vents on the unit. These areas collect dust and allow for debris to enter the heater, which can be a fire-risk. They also increase the risk of fingers poking through, which is a huge safety concern. Oil filled heaters are fully enclosed, no grilles or vents to worry about. The lack of grilles and vents also means no worrying about blocked air flow; the unit can be placed wherever you want inside the room.

  • Safety Features:

Most oil filled heaters that are available for purchase feature built-in safety features. The two most popular features are the overheat protection and the tilt-switches. Both of these safety features immediately shut the heater off if a problem is detected. The tilt switch is triggered when the unit is tipped or knocked over. The overheat protection will shut the unit off if the units starts running too hot.

​As with all products to stay safe you need to read and follow the directions that are included inside the box. Not using the product as intended can have serious consequences.
