These heaters do not burn up oil, so you will not need to constantly worry about replacing it. They are electrically heated; the oil is used as a heat reservoir (i.e. a buffer), and not as a fuel. Oil has a relatively high specific heat capacity and a high boiling point; these qualities allow it to store a large amount of thermal energy in a small volume while remaining in liquid form.

When heated by the heating element, the oil will remain warm for prolonged periods of time, transferring the heat to the metal wall via convection, through the walls via conduction, and to your surroundings via convection and radiation.

The large surface area allows more air to come into contact with the heater at any given moment, allowing for the heat to be transferred more rapidly from the heater into the room. These heaters work via convection: the warm air they generate moves upwards, displacing the cold air to the bottom of the room, where it will, in turn, be heated to a warmer temperature.

There are plenty of oiled filled heaters on the market. Some over the top expensive with many functions and options included, and many which just get the job done. We have included a buyers’ guide down below to let you know and hopefully make you aware of some properties you might want to look for when you decide to go on and purchase one for your home or office.

What To Look For When Buying an Oil Filled Radiator Heater

An oil filled heater is a specific tool for heating on its own. There are many aspects to consider but mainly let us talk about how these heaters use oil to make heat.

Convection heating has been used for a long time in heating sources and oiled filled radiator heaters have been used for just as long to make our homes warm and welcoming without the use of anything more than electricity.

There are quite a few advantages when you opt for an oil-filled heater as well as some disadvantages and this is what this guide is made for. To make sure you make the right decision, next time you decide to get a new heater.


Oil heaters are extremely quiet, unlike the electric ones, which act as blowers. The only noise you would hear from an Oil heater is the adjustment of the thermostat.

Safety Features

Many, if not all models, have plenty of safety features provided so no harm could come to your room, home, office, or any area you decide to heat up. Anti-tip-over measures are usually in place if you accidentally tip the heater over, in addition to overheating turn-off functions in case you forget you left the heater on at some point.

Energy Efficiency

If you want to save more than a few bucks on your power bill, then definitely opt for an oil-filled radiator heater. Not only do they use oil, which would never need to be changed, but also most models have ECO modes or are programmable to a point where it will save you every penny possible and not work an extra minute if the room you are trying to warm up is already at the desired temperature.

Digital thermostats and multiple programmable cycles are available in many models to let you pick what is best for your environment. Energy efficiency should be a deciding factor when looking for a heater.

Air Dryness

Unlike air electric heaters, oil-filled ones do not dry out the air and you do not need to open a window every once in a while, to let air in to move around the room because it might feel dry. Like air conditioners, fan-based heaters just turn to dry out the air in the room, while oiled heaters just take the same air and turn it to warm without suffocating the room.


A funny smell is common in oil appliances. Just like you might need a few cycles to rid your new oven from a fresh smell that smells like oil when it burns, oil-filled radiators might have the same exact issue at first until you get them going. But at the end of the day, it is a small price to pay for what they provide in terms of energy, heat, and bill savings.

Wrong Pick

Plenty of people make the wrong pick when it comes to oil heaters because they think the bigger the heater, the bigger the room they are going to be able to heat up.

At the same time, you could easily select a more convenient option of the many available on the market and have the same final result instead of spending a couple of hundred dollars more on a product you do not really need.

What is the best oil filled radiator heater?

In our professional opinion, the best oil filled radiator heater is the 1500W oil filled radiator space heater from Aikoper. It has every setting one unconventional user might pick and at the same time, it is perfect for anyone looking for energy efficiency. The price is more than right and competitive.

What you see is what you get. A fantastic ribbed oil filled radiator which can heat up a medium to a large room to any temperature, without sucking the air out of it, a digital thermostat set to be adjusted at any point. And most of all it is safe for use by anyone, any place, anywhere.


Which heater works best to suit the heating needs of your office or home? Do also note that while these oil-filled radiator heaters have lower surface temperatures than their gas counterparts, you are still advised to ensure that there are no objects within three feet of it (especially fire risk items such as clothing).

Do also avoid placing them in damp areas such as bathrooms or laundry rooms, since high levels of moisture and humidity can damage the heater’s internal components.

With these safety precautions in mind, you will be able to sit back, enjoy the warmth, convenience, and cost savings they provide throughout the winter.

  1. They all work well … but dry you out like a fruit roll up. You have to vigilantly keep fresh air flow every hour or so. It gets mighty cold up here. Gonna be mighty cold this winter. Time to re-up on heaters.
