How to choose your oil bath radiator

The choice of an oil bath heater must be made with particular attention. The goal is to find a model whose power is adapted to your home, whose use is intuitive and comfortable and whose price is appropriate to your budget. Here are the criteria to consider in order to make a successful purchase.
choisir radiateur bain d’huile

#1 - The power

The power will be the first factor of choice to take into account. It defines the heating performance of the oil bath heater. In general, the models available on the market have a power ranging from 500 W to 2500 W.

The choice is made according to the size of the house. The larger the room to be heated, the more powerful the oil-bath radiator must be. On average, 60 W per square meter is required for optimal heating of a well-insulated room. Oil-filled radiators with adjustable power are preferable. This will allow you to adjust the heating performance and energy consumption according to the size of the room and the level of heating you want.

#2 - The type of installation

You can choose between floor-mounted models, wall-mounted oil-bath heaters and mobile models with casters. It all depends on your use and the space you have available. If you plan to move the heater from one room to another, a model with wheels is ideal. Check the weight of the heater and whether it has a handle to make it easier to move. You can opt for a fixed model, to be placed on the floor or hung on a wall, if the appliance is used to heat a single room. In this case, plan for some installation work, especially for wall mounting.

#3 - The features

In general, an oil-bath radiator has power, temperature and on/off time adjustment functions. On some models, these features are accessible from a control panel with a display. A remote control for remote settings is also very convenient. For the timer, check the programming range. It can range from 24 hours to 7 days. Some models can serve as a heater and humidifier. The most advanced ones even have onboard blower systems.

#4 - The ventilation

The ventilation system is not always offered on oil bath heaters. This type of heater heats and distributes heat very well even without a fan. However, the presence of a ventilation system can accelerate the heating of the radiator. The heating time will therefore be shorter.

#5 - The design

The oil bath radiator is primarily a functional device. However, it is called to be part of the environment of your home. The decorative aspect is not to be neglected. The look varies greatly from one model to another. Some oil bath radiators have visible columns. They are contained in a wall that promotes convection. In addition, some models are thinner or larger than others. The choice of design depends on your tastes, but also on the style of decoration of your home.

How to maintain an oil bath radiator?

The oil bath radiator requires almost no maintenance. Just dust the walls of the columns regularly to keep the device in very good condition over the long term. Clean with a wet, wrung-out cloth, without detergent, and let it dry. Wait until the unit is cold before cleaning. When the oil bath heater is not in use, it should be unplugged and stored in a place protected from moisture, dust and heat. Keep the heater upright when storing.

After many years of use, the heat transfer fluid may become depleted. The heater then loses much of its heating performance. In this case, you can call in a professional to replace the fluid and give your oil-bath heater a new lease on life.

The different types of oil bath radiators

There are several types of oil-filled radiators. Knowing the features and benefits of each type will help you choose the model that best suits your needs and expectations.

The mobile oil bath radiator

radiateur bain d’huile mobile

The oil-bath radiator is generally used as an auxiliary radiator. It supports the central heating system when needed. Because of this, some models are portable. When temperatures start to drop, you can take your portable heater out of the closet.

It is placed in the room to be heated and can be moved to other spaces in your home. As a result, it is equipped with a carrying handle and wheels. Its mobility is a real asset since you can enjoy its heat in different rooms of your home without having to install anything.

Note, however, that oil bath radiators are relatively heavy. It therefore requires a certain amount of effort to move it, especially between floors, despite the presence of casters. It is necessary to avoid contact with the walls of the tubes which are hot when the appliance is turned on.

The fixed oil bath radiator (wall or table)

radiateur bain d’huile fixe

Contrary to the mobile oil bath radiator, the fixed models are to be hung on the wall or placed on the floor and therefore cannot be moved from one room to another. Opt for this type of heater if you need a fixed heater in the same space. If it's a floor model, you'll just have to find the right place for it. In general, it is quite heavy and has no wheels for moving.

In the case of the wall-mounted oil bath heater, you should carry out the installation before using it. The installation requires tools such as a drill and screwdriver, but also a fixing kit adapted to the model. After this installation, you will not have to do anything else to use your oil bath wall heater. Generally, this type of oil bath radiator is thinner. It has a better decorative appearance than the models mounted on wheels.

Oil bath radiator or radiant radiator?

Oil bath radiator

The oil bath heater works on the basis of convection. A resistor transmits heat to a heat transfer liquid, in this case oil. The heat from the liquid is then transferred to the walls of the radiator columns. This heat is distributed by convection throughout the room. The oil bath radiator takes longer to heat up.

Nevertheless, it is particularly efficient. When the appliance is switched off, the heat transfer fluid retains its heat for a longer period of time and the appliance continues to heat the home. This compensates for its relatively high energy consumption compared to other types of radiators. The oil bath radiator is more affordable than other types of heaters in its category. Best of all, it requires almost no maintenance except for models equipped with ventilation.

Radiant radiator

The radiant heater is more recent than the oil bath models. It retransmits the heat from the resistance by electromagnetic infrared radiation. This technology has the advantage of rising rapidly in heat and increasing the room temperature in a short period of time. It also transmits its heat to all surfaces in the room, walls, floor and furniture.

Note, however, a certain difference in temperature between the floor and the ceiling. It is important to note that the surface of the radiator can be hot. It is therefore advisable to keep it well away from children and heat-sensitive furniture.


The radiant heater is more recent. However, it has some defects that the oil bath radiator does not have. In any case, the oil bath model can very well be equipped with modern features that make it more efficient and easier to use. It is therefore advisable to equip yourself with it, especially if you want to have an efficient and affordable space heater.

Why buy an oil bath radiator?

Heating comfort

The oil bath radiator diffuses a soft and homogeneous heat. It also does not dry out the air in the room by raising the temperature. Thus, it provides a good heating comfort when winter arrives.


The radiator is part of the inertia heaters. This means that it continues to restore heat even after it is turned off. This is possible thanks to the heat transfer fluid that retains the heat and releases it gradually. Thus, even when you turn off your oil bath radiator, it will continue to heat the room for several tens of minutes. This represents significant energy savings over the long term.

Energy consumption

Of course, the oil-bath radiator is not the most energy-efficient type of radiator. Nevertheless, its energy consumption remains perfectly reasonable and its regular use will not explode your energy bills.

Ease of installation

Mobile models require virtually no installation. Just place the unit in the right place, plug it into a power outlet and enjoy its gentle, even heat. Wall-mounted models are not very difficult to install. The wall-mounting kit is usually already included with the oil-bath heater.

The price

Oil-filled heaters are among the most affordable auxiliary heaters. If you have a limited budget, choose this type of radiator. It is inexpensive and yet very effective in heating the rooms in your home.

Turn on the heater early enough

You should know that the heating time of the oil bath radiator can be relatively long. For this reason, it is advisable to turn it on a little earlier in order to enjoy its heat at the right time.

A model with a ventilation system

In order to reduce the heating time, you can also opt for an oil bath radiator equipped with a fan system. The fan will accelerate the heat rise of the heat transfer liquid.

Program the timer

The vast majority of oil bath radiators have a programmable timer. This means you can record the time the heater is turned on and off. The programming can be daily or weekly. Make full use of this feature to limit handling and control the energy consumption of the radiator.

An oil-bath heater for a home with low ceilings

The oil bath radiator is most effective in rooms with low ceiling heights. If the room to be heated is much higher, choose another model for optimal heating performance.

The oil-bath heater as a space heater

The oil bath radiator is generally used as an auxiliary heater. It cannot replace the central heating system. Use it to provide more heat and support the central heating in certain living areas.


Is the oil-bath heater noisy?

No! The noise emission is very limited on this type of radiators. This increases the comfort level of use. This low noise emission of the oil bath radiator is also ideal if you plan to install the appliance in a bedroom. It will be able to operate without disturbing your sleep.

How often do you change the oil in an oil-bath heater?

This type of radiator is powered by an electrical system. The oil is not used as fuel, but as a heat transfer fluid. It is therefore not changed very regularly contrary to what one might think. It takes several years for the liquid to deteriorate. So you wouldn't have to drain it for a very long time.

How do you change the oil in an oil-bath heater?

Over time, the heat transfer fluid loses its ability to retain and transmit heat. It must be replaced. Draining and replacing the heat transfer fluid should be done by a professional. The operation is essential to avoid a drop in radiator performance.

Are the walls of an oil-bath heater hot when it is turned on?

Yes! When heated, the liquid inside transmits heat to the walls. It is therefore highly recommended that you keep children away from the radiator. Also, keep some distance between your heater and easily flammable objects and furniture.
