A MIni Guide To Oil Filled Radiators And How They Work

Oil filled radiators are household heating appliances. As their name suggests, they are filled with oil. In many appliances and engines, oil is used as a lubricant and coolant. However, in radiators, oil is used as a heat reservoir. The best oil heaters contain a special kind of diathermic oil.

This type of oil has a high boiling point and specific heating capacity. It’s able to retain heat longer than most liquids and remains in liquid state longer even when exposed to extremely high temperatures.

Oil filled radiators are made up of a main body containing the diathermic oil. The body design includes fins and columns which disperse heat to the surrounding environment. It also contains a heating element which actively heats the oil. Other features you’ll find on modern oil filled heaters are a control panel and thermostat.

Oil filled radiators are electric appliances. As electricity passes through the heating element, it heats up the oil which flows through the columns passing heat through the fins to the adjacent environment. Once the desired temperature is reached, the built in thermostat shuts the unit off. However, due to the oils ability to retain heat longer, constant room temperatures are easily maintained.​

Types Of Oil Filled Radiators

Oil filled heaters operate in the same way as the radiators and there are no major types to choose from. However, in order to find the specific unit that meets your heating needs, here are some of the important considerations to make.

Considerations To Make When Selecting The Best Electric Oil Heater

Size and weight

Many of the best oil filled heater appliances for home use are compact and highly portable units. They don’t require special installation. However, bulky units can take up a lot of space and be difficult to transport. You should try to find a unit that’s small enough to fit within the space available and light enough to carry around. If it’s a large unit, consider one with caster wheels.

Power rating

Many of the best oil heaters for home and office use come in power ratings between 500 and 2500 watts. A high power rating indicates that the heater will take a shorter time to heat up the oil. If possible, you should also invest in a unit with more than one heat setting. This gives you better control over how much heat it generates.


One advantage of investing in an oil filled heater is that its safer compared to traditional heating like firewood and gas. However, this doesn’t mean that these units are completely safe. You’ll need to find a unit that comes fitted with safety features such as a thermostat, thermal safety cut off, sturdy topple free construction and anti-freeze settings.

Other important considerations

Some of the other important considerations to make when choosing your oil heater include ease of use, low or maintenance free operation, built-in timer, design, price, brand and guarantee.
