What Is an Oil Heater?

During cold season a good electric oil heater is a worthy investment in creating a comfortable indoor climate. The Oil Heaters are characterized by ease of use, light weight, and almost noise-free operation.

An oil heater looks like a traditional radiator. The way it works is as follows: once the device is plugged in, a heating element inside begins transferring heat to the mineral oil, thus heating the radiator surface which, in its turn, releases heat into the room. Such space heaters can reach a maximum surface temperature of 150 degrees F. So, it goes without saying that safety rules must be observed when using the device.

If an oil heater isn't enough for warming your living space, you may consider more powerful gas heaters which are capable of warming up to 1500 square feet premises. You can also select one of the space heaters to meet your specific needs.

What Features to Compare

The first thing you should pay attention to when selecting an oil heater is the Power, which is particularly important when it comes to the room space you need to warm. For heating small areas of 100 square feet, it's better to choose the models with the power of 1000 Watts. If the heated area ranges from 150 to 200 square feet, it's advisable to consider the models with the power of 1500 Watts. If the premise covers an area of more than 300 square feet, it's better to buy a more powerful heater or even several ones. You should keep in mind that the number of fins also influences the heating area. The more fins the unit has, the more heat it generates without overheating. For warming up areas of up to 200 square feet, the optimal decision will be to select the heaters with 5-7 fins.

After you've decided on the coverage area, it's time to consider the Controls. In this respect, take notice of the On/Off programmable timer availability. The timer prevents energy overuse as it provides an operation within the pre-set time. The models with a digital display are designed to provide ease of operation, while a variety of heating modes allow you to select the optimal indoor temperature.

Usability is another essential aspect you should bear in mind. Quite often, heaters are moved from one room to another, and this is where wheel casters are important. Also, you've got to think of the unit dimensions and weight to find a convenient place for it. Yet, take into account that the more compact a unit is, the less power it generates, hence, heating smaller areas.

When using oil-heaters, Safety is definitely a matter of great importance. Since oil-filled radiators can reach up to 200°F, make sure they are not placed close to the high inflammable furniture surfaces. Currently, oil heaters feature an overheat protection (thermal cutoff) and some models even have a tip-over switch.

FAQ:

Q: When is it right to buy an oil heater?

A: If you live in a small apartment or you need to heat a single room, buying an oil heater may be the right decision. For heating uninsulated places such as a garage, etc. we'd recommend you to pay attention to other types of heaters which you may also find on our website. Think of how fast you want your room to be heated. Most of the oil heaters will take quite a lot of time to heat up. The advantage is though, they are able to maintain the warmth considerably longer than many other heaters, too. If you don't mind waiting a little bit, the oil heater will suit you perfectly well.

Q: Which material is the most appropriate for the oil heater?
A: The best material for oil heaters is steel because it's solid and durable. Besides, steel is easier to clean than many other materials. Some models of oil heaters may have an enamel finish that prevents rusting.

Q: Which size of the radiator should I choose?
A: The size of the appliance will tell you how big the area it's able to effectively heat. The bigger your place is, the more powerful radiator you will need. As a rule, the power of 1500 W is enough for heating rooms of up to 150 sq. ft in size. You should also pay close attention to how many fins the heater consists of. The same rule applies - the more the better.

Q: What's the best place for an oil heater in the room?
A: You can set it basically anywhere in your house. The only thing you should keep in mind is that it's not advised to place it in close proximity to inflammable objects. If you don't think you've got enough place for a free-standing model, there are many good wall-mounted heaters to consider.

Q: Should I refill my oil heater?
A: No! The oil that fills the heater circulates around the fins due to the special element that works from electricity. The oil doesn't burn and heats up only from the element, so the amount of oil doesn't decrease. As a result, there's no need to refill the heater.

Q: I noticed an oil leak from my heater. What should I do?
A: If your device started leaking oil, it means that the heater broke down. Be sure not to turn it on and do not try to fix it on your own. If you notice leaks while the heater is on, the first thing you need to do is immediately turn it off and unplug. Hot oil can cause burns, so be very careful and make sure to maintain it properly.

Q: Are there any safety tips for running an oil heater?
A: You should always switch it off and unplug it from the mains when not in use. Do not allow your kids to touch it when it's hot. Even though most of the heaters have a tip-over protection, it is still better if children do not play around it. Keep in mind, heaters are designed for keeping you warm but not drying your clothes. Anything you put on a top cover may spark off a fire. We would also recommend you to place heaters farther from inflammable objects despite the fact that they do have overheat protection function. Safety first safety always. Also, never use your heater if you notice oil leaks.

Q: Is there any way to save on electricity bills using an oil heater?
A: Because oil heaters work from electricity, you might worry about high electricity bills. To avoid overpaying, choose the heater that has an embedded timer which will automatically turn the appliance off after a certain amount of time. The oil heater with a thermostat sustains an even temperature level and in this way preserves energy.
