An oil filled radiator is a kind of a radiator which requires oil to function and helps warm the house centrally. This appliance is useful especially for those who live in the colder regions of the world or those who experience colder weather conditions. One of the main problems with such a radiator is oil filled radiator not heating. This basically defeats the purpose of having the device altogether. There could be many reasons for this and this article will help you identify a few and also find solutions to them. They are given as follows:

1. Thermostatic valve cut off

REASON: One of the most common reasons for oil filled radiator not heating could be thermostatic valve cut off. This may happen due to the temperature difference between the setting and the room.  Sometimes when the room temperature is higher than the setting then this could happen.

SOLUTION: The best way to solve this issues is to turn the valve to bring it to a higher temperature setting. This will help lower the temperature difference.

3. Airlock in pipe work

REASON: Another reason why your oil filled radiator may not be heating as much as it should is airlock in pipe work.  This usually happens in the case when the radiators are below the level of the feeding pipes.

SOLUTION: In this case you may have to change the level so that the airlock can be removed and the radiator begins to function back normally and starts heating.

5. Bleeding required

REASON: If you haven’t bled your radiator for a long time then it could be creating certain problems in the heating.

SOLUTION: Thus it is necessary that you bleed out steam from the radiator. This needs to be done every now and then to ensure optimum performance.  However if your appliance needs bleeding on a very regular basis, then this could be a problem which needs to be resolved. To bleed steam out of an oil filled radiator you can use a radiator key or a screwdriver to turn the valve counterclockwise until water starts to drip out. This shall release all the trapped air.

    It is a shame when someone goes out of there way to help people and in return you get mocked by people who don’t know very much about radiators.
    There are a large range of different oil filled radiators and some have sealed systems and some are accessible and some are not but all can have these side affects.
    I know you know your stuff and if they want accuracy its not steam its Nitrogen from the rust that comes from the metal that tends to be weathered.
    I know this could have faults in the script too but i was always taught to show respect to those that help me not to cuss them, Some never got that what a shame.

    I had my oil filled radiator heater for only one winter and it won’t come on now. I’m reading that they can last up to 15 years. So needless to say, I am very dissatisfied with this product.

    Doubt you’ll read this, but this helped immensely. I had been using the 900 watt setting on my space heater and it seemed like my room was constantly cold. When you posted this Post and showed the thermal cutoff being on the high side, I started using the 600-watt setting. Now my room is MUCH more comfortable. Thank you!
