Do Oil Radiators Smell?

Do Oil Radiators Smell?

Oil-filled radiators do not typically produce any noticeable smells. However, if you are noticing a smell coming from your oil radiator, it could be due to several different factors, including material damage.

Oil-filled radiators normally do not generate any discernible odours. However, if the radiator has a covering of a new paint, dust or other pollutants, it may generate a faint, dusty, or musty scent, when switched on. If you notice strong odour, such as that of burnt plastic or rubber, it might signal a problem with the unit, possibly an oil leak or an interior problem.

In this case, you should switch off the radiator and get it checked by an expert to establish the source of the odour and resolve any potential issues.

Causes of Odor from Oil-Filled Radiators

These are the potential reasons of a burned smell from an oil-filled radiator that our study report established from various user reports. This would assist you in considering the causes, and the next section will provide remedies to stop experiencing it again.

Dust and Debris

Dust and dirt may have gathered on the surface of the radiator if it has not been used in a while. When the radiator is switched on, the dust and debris might be burnt or evaporated, emitting a burning or scorching odour.

This may also happen to a brand-new oil-filled radiator heater when it burns off factory dust or new paintwork. So dont worry, the smell will fade with the use, can take weeks or as little as a couple of days.

New Paint Job Causes Unpleasant Odour

Many cheap oil-filled radiators have poor paint jobs, which is why you get a burnt incense when you use them. It is one possible explanation that is commonly discovered in new and repainted radiators.

This odour is caused by surface paint and will fade over time when the radiator is heated and utilised for regular heating.

High Humidity Levels

High humidity does not normally cause an oil-filled radiator to emit a burned odour. High humidity, on the other hand, might promote to mould growth. This occurs when warm weather produces high humidity, and the moisture causes moulds to develop and form spores.

When the radiator is restarted, the spores become airborne and can cause odours. This will have a burning smell, but it is not a major deal and will fade away after the first usage.

Malfunctioned Thermostats and Overheating

A faulty thermostat might cause an oil-filled radiator to emit a burned odour. This can happen if the thermostat is stuck at the maximum setting, causing the heater element to run continually and overheating.

If this is the case, replace your radiator or go for repairs. It is possible that the radiator will stop working in the near future.

Physical Damage and Oil Leakage

The most prominent reason for burnt smell is the damaged oil-filled radiator that might begin to leak oil.

If you observed this, it is crucial and should not be overlooked, as it might result in property damage and fire hazard.

In such case, we recommend that you take physical damage seriously, and schedule a repair service to get fixed your oil radiator. Doing so will overcome reduced heating efficacy and possibly dangerous scenarios.

How to Eliminate the Smell of Oil Heater

We’ve discovered a couple solutions to the odour emanating from your oil-filled radiator. Some methods could be easy to confront while others take an effort to obliterate the nonsensical stink.

Clean the Surface

Oil-filled radiator heaters, like any other equipment, will collect dust after months of exposure. So, what you’re smelling is dust heating up on the surfaces of the fins and rods.

To fix the issue, you can try vacuuming the heating system or wiping it down with a damp cloth. This will help minimize the odour once it dries.

Check for Electrical Problems

A burnt smell may also be caused by electrical issues with the oil radiator. This could be due to a faulty power cord, a malfunctioning thermostat, or a problem with the heating element.

To prevent any damage, it’s important to unplug the radiator and have it checked by a electrician to get it fixed as soon as possible.

Physical Damage and Oil Leaks

When the thermal oil inside the radiator leaks, it will emit a strong burned odour. This might be caused to a faulty seal or a radiator fracture. In this case, you must get it repaired by a repair services.

In this case, I’d recommend filing a warranty claim to manufacturer if the warranty isn’t invalid, otherwise refilling the Diathermic oil and having it sealed again is costly. You can also think of a replacement and save the unnecessary hassle of repair works.
