What Is an Oil Filled Heater and Why Do I Need One?

When the colder months of winter come along, it’s not the temperature that we dread. It’s the utility bills that are coming our way. The change from summer to winter can bring an additional cost of hundreds of dollars per month in some homes. An oil filled heater is an easy way to limit these utility costs because it helps your existing HVAC system work more efficiently.

It can also operate as a stand-alone heating unit if you prefer. If you choose a model that can operate at 600 watts, then you may even have an off-the-grid heating solution because these space heaters are one of the few that can work with solar power or other homestead-style power sources.

These heaters work efficiently because the oil within them is heated as a reservoir. It maintains the heat for a prolonged period of time and transmits it into the room environment through the convection process. As the air comes into contact with the heated components, it warms it up and eventually makes the room warmer. Because the oil stays heated, less energy needs to be used because constant heating isn’t required.

Heat flows upward and then the process repeats itself. There’s no fan, so there’s no frustrating background sounds. You just receive the warmer room that your home needs to have.

What Are the Benefits of an Oil Filled Heater?

The primary benefit of owning one of the best oil filled heaters is that they have lower overall maintenance costs. They just warm up the oil in them, so there is never really a need to replace the oil unless you happen to tip one over for some reason and there’s a mechanical failure which allows a leak to take place.

Then add in the lower overall utility costs that come with this type of heater because of its energy efficiency and you save even more. There isn’t the need to supply this type of heater with a constant supply of power. Even when power is needed, it takes less energy to replace the heat loss the oil has experienced. Many space heaters need to use 1,500 watts of energy in order to heat 250 square feet. An oil filled heater may only need to use 300-400 watts to heat the same space.

Oil filled heaters also have a number of safety features included with the design so that there aren’t unintentional injuries. The heating elements don’t become blistering red hot when operating, so if you bump the heater, you have fewer worries about experiencing a bad burn. If the heater does get warmer than is safe, the automatic shut-off features are included so the heat levels stay regulated.

They also fit into smaller spaces than other types of space heaters, giving you more placement options throughout your home or office.

Certain Disadvantages with Oil Filled Heaters and How to Solve Them

The one main disadvantage that comes with an oil filled heater is the time it takes to heat a room. It’s more of a slow build-up of temperature instead of a fast temperature change. If you need instant heat, this probably isn’t the first solution to consider.

Because there is oil being heated for warmth, there can be a certain “oily” odor which emanates from these heaters from time to time. It can be especially noticeable in cold weather when you first turn on the heater. The odor typically fades away, but can still be bothersome to some people. Having good ventilation in the room often prevents this odor from being noticed.

We’ve also found that some of the cheaper models in this category can, from time to time, miss on the temperature settings by a few degrees. Each model is a little different, so it can take some tinkering to get the temperature settings right for your home.

The best oil filled heater reviews will let you compare features, determine overall quality, and let you know if that heater can meet your specific needs. That way, with this information in hand, you can avoid the vast majority of disadvantages that are reported with this type of heater.

What Are the Prices of Oil Filled Heaters?

Although these heaters tend to be priced higher than other space heaters, the investment will eventually pay for itself through utility savings. Most households can expect to pay at least $100 for heaters in this category. The best oil filled heaters with premium features may exceed $200 in price, but they also tend to heat rooms that are 300-400 square feet in size.
