In this article, we will answer all your burning questions, including: are oil filled radiators safe? 

Where to Put Oil-Filled Heater in Your Room?

When using an oil-filled heater, it is important to consider where you place it in the room. It should be placed on a flat, stable surface away from furniture and curtains, and away from any flammable materials such as paper or cloth. 

Make sure there are at least three feet of clearance around the heater so that no one can accidentally touch it while it is running. Additionally, it is best to keep it away from windows and doors, as cold drafts can reduce its efficiency. 

Finally, never place the device near water sources such as sinks, bathtubs, or other containers of liquid.

5 dangers of leaving oil-filled heaters overnight

Burns From Contact With Space Heaters

Burns from contact are one of the most common dangers associated with leaving an oil-filled radiator on overnight. 

Its metal surface can become extremely hot, which can cause serious burns if someone accidentally touches it. It is important to keep children and pets away from it, as they may not understand the risks of coming into contact with a hot object. 

Additionally, make sure that the heater is placed on a flat, stable surface away from furniture and curtains to reduce the risk of accidental contact.

Placing The Heater On An Unstable Surface

Placing an oil-filled heater on an unstable surface is a major safety hazard. 

If the surface is not flat and level, the heater can easily tip over, potentially causing burns or even starting a fire. It is essential to ensure that the surface is stable and secure before placing the heater on it. 

Finally, make sure the area is dry, as wetness can increase the risk of electrical shock.

Leaving The Heater Too Close To A Flammable Object

One of the major dangers of leaving an oil-filled heater too close to a flammable object is the risk of a fire. If it is placed near curtains, furniture, paper, or other combustible materials, the heat can cause them to ignite. 

Make sure to keep the heater away from any flammable materials, as well as any water sources, to eliminate this danger.

Allowing Oil To Leak From The Oil Heater

Allowing oil to leak from an oil heater is a serious safety concern. If the device is not properly sealed, oil can leak out and pool on the floor or other surfaces. 

This can be a major fire hazard, as the oil can easily catch fire if it comes into contact with an open flame or other heat sources. Additionally, the liquid can be dangerous to touch, as it can cause skin irritation or burns. 

It is important to regularly check the heater for any signs of leaking oil and to ensure that it is properly sealed.

Using The Wrong Fuel In An Oil Heater

Using the wrong fuel in an oil heater is a major safety hazard as well, as it can cause the device to malfunction, potentially leading to fires, explosions, or other serious accidents. 

Additionally, this can cause damage to the heater, resulting in costly repairs or even replacement. So, make sure to only use the fuel specified by the manufacturer to reduce the risk of an accident or damage to the radiator.


Oil-filled radiators are a great way to heat your home or office safely and efficiently. They provide steady, even warmth that can be adjusted to the level you desire. Plus, they are relatively inexpensive to purchase and operate. 

With all the advantages they offer, these devices are a great choice for anyone looking for a reliable source of heating. If you’re ready to take the plunge, check out our selection of oil-filled radiators today!
