The colder weather has begun to kick in. It's the perfect time to snuggle in with a luscious Chai Hot Chocolate... what could make this winter more warm and toasty? A room heater! Adjust your room to your preferred temperature and enjoy winter in the comfort of your home.


So, if you're looking to buy an Oil Filled Radiator/Room Heater, there are some things you should know to look for to make the right purchase.

How do Oil Filled Radiators (OFR) work?


OFRs function using thermal fluid technology. They have a metal body and contain a heating element held especially within a heat transfer fluid. The fluid consists of a type of oil, which is where OFRs get their name.

Most OFRs have caster wheels, which help you move the device easily to your desired location, without worrying about how heavy they are.

OFRs are mains-powered, meaning you don't need to fret about power connections, you can easily plug them into any power outlet and they're ready for use!

The heat transfer fluid contained within the radiator stores heat and gradually releases it. This means that your OFR will continue to have a heat output even after being switched off.

OFRs have many curves alongside their cavities which provide a larger surface area. This allows more air to come into contact with the radiator for optimal thermal transfer and heating power.

OFRs work by both convection and radiation to release a gentle form of heating which provides a comfortable ambient temperature.

How to use an Oil Filled Radiator?


As previously stated, they generate a comfortable ambient temperature but are still quite energy-intensive. Hence, it's recommended to use them as space heaters, rather than as a sole heating source. Used in small spaces, or as an assistant to your main heating system, is the ideal use for OFRs.

Their caster wheels also make OFRs an excellent portable device.

What to understand about OFR design and power wattage?


No matter what the power is, the more curves (known as fins) that a radiator has on each side indicate that the OFR has a larger surface area. As previously explained, larger surface areas will result in higher heat output.

More surface area = more contact with air = higher efficiency.

#BorosilTip: Larger radiators will perform better in bigger more spacious rooms.


Follow this simple formula to choose the correct power wattage for your home:

100 W / m² (if you want pleasant warmth).

60 W / m² (if you want a very well-insulated home).

What features and accessories do OFRs have?


Wheels: Select models that come with caster wheels. OFRs are quite heavy, and these wheels help to easily move them around.

Carrying handle: These are especially important, they assist in handling the OFRs since they are heavy.

Tilt protection: This stabilizes your radiator and prevents it from falling over.

Adjustable heating power: If you want to adjust the temperature, opt for models with this feature.

Overheat protection: This feature ensures safety by turning off the OFR if it gets too hot.

Screen display: A useful visual representation to easily change modes and settings with ease

Control lock: To prevent any danger to young kids.

Programming: Some models have several programming options.

Electric thermostat: Provides more precision than electromechanical devices.

Humidity control: Allows you to adjust the level of moisture in the air (convection heating does tend to dry the air slightly).

Cord winder: Handy for discreetly winding up your power cables.

Extension cable: A longer cable to reach farther sockets!

Timer: Useful for night usage, the timers can be used to switch off your radiator at set times (can also be replaced by a programmer).

Design: The traditional design seems to be unchanged, but now it's also offered in different colours!

OFR warranties, maintenance and prices!


OFRs are sturdy products, which is why they usually come with long warranties. The longer the warranty, the higher the guarantee of a reliable product.

It's still important to watch out for any changes or inefficiencies and act accordingly.


OFRs need next to no maintenance. But if you notice any leakage, immediately turn off your device and contact your manufacturer. Other than that, make sure to dust your radiator once a month as dust can lead to energy loss and odour.


Usually, radiators are reasonably priced. They are the most inexpensive heating devices on the market! You can sort through all your requirements before making a cost-effective purchase.
