How Long Does an Oil Filled Radiator Take to Warm Up?


Oil filled radiators are extremely popular, and usually, one of the first types of portable electric heaters people consider. In this guide, we will look at how long does an oil filled radiator takes to warm up.

How Long Does an Oil Filled Radiator Take to Warm Up?

An oil radiator can take around 5–10 minutes to warm up, depending on size. Unlike convector or fan hearts that give you heat within a minute, oil filled radiators have to warm an element inside, which warms the oil, and for this reason, it can take around 5–10 minutes.

Although oil filled radiators take longer to warm up, they take longer to cool down, meaning they provide heat for quite a while after they have been switched off. Convector heaters and fan heaters stop producing heat once they have been switched off.

How long an oil filled radiator takes to warm up is different to how long it takes to warm a room, below, we will look at how long it takes an oil filled radiator to warm up a room.

How Long Does an Oil Heater Take to Warm a Room?

A room that is 20 square meters with double glazed windows and somewhat good insulation can take around 25 minutes to warm a room with a 2000 watt oil filled radiator.

If you live in a new house with excellent insulation, a 2000 watt oil filled radiator will warm a room that is 20 square meters in around 15 minutes.

If you live in a poorly insulated property with single glazed sash windows, I would recommend you get a fan heater as they pump out hot air fast, and will throw heat into a room quicker than heat is lost through poor insulation. An oil filled radiator will be very poor at providing heat and will require you to run it longer, or buy a larger sized oil filled heater, meaning it will cost more to run the oil filled radiator,

How Long Do Oil Filled Radiators Last

On average, a good oil filled radiator can last 15–20 years. This will be dependent on use, providing you take care of the outer case, the internals, and oil can last up to 20 years, extreme heavy usage will see its life span decrease. Check this out to learn how oil filled radiators work.

Do You Have to Replace Oil in an Oil Filled Radiator?

No, you do not have to replace the oil. The reason why you do not have to replace the oil is because it is not used as a fuel to heat up the radiator, it is a reservoir that gets heated by the internal elements to provide heat. The oil only ever gets warm enough to provide heat, and not burned as a fuel to provide heat.

Are Oil Heaters a Good Heater

Yes, they can be excellent for certain environments, they provide a nice comfortable heat, make no noise once the oil is hot, some oil heaters can make a small amount of noise when heating the oil. Some oil filled radiators come with a remote control for easy operation, and are starting to be produced in impressive modern designs.
