How to choose your dry inertia radiator

Here are the parameters not to be neglected when buying a dry inertia radiator that will allow you to enjoy exemplary thermal comfort while being energy efficient.

#1 - The power

This criterion is to be defined according to the surface of the room in which it will be installed:

  • Less than 750 Watts for a room of less than 10 m².
  • Between 750 and 1000 Watts for a room of 10 to 15 m².
  • Between 1,000 and 1,500 Watts for a room of 15 to 20 m².
  • Between 1,500 and 2,000 Watts for a room of 20 to 30 m².
  • Between 2000 and 3000 Watts for a room of 30 to 40 m².

#2 - The size

It should be determined according to your personal preferences and the final touch you want to bring to the room. You have the choice between:

  • the vertical radiator which saves floor space
  • the horizontal model which is the most common model
  • the plinth radiator is particularly aesthetic and can be placed under a window
  • the low radiator is appreciated for its discreet and compact character
  • the square radiator fits easily into the decoration of a room thanks to its great discretion.

#3 - The warranty

You should never buy a space heater without a warranty. If something goes wrong with your heater, a warranty promises repair or replacement. The length of warranty offered with each heater is a good measure of its quality. If there is a warranty, ask the manufacturer for a list of parts covered by that warranty.

#4 - The options

You have a lot of features to choose from, namely:

  • The remote control function via your smartphone by opting for a connected radiator, perfect for reducing your energy consumption in an optimal way
  • The possibility of adjusting the temperature remotely by choosing a remote-controlled radiator to better control your electricity consumption
  • The possibility of delayed start-up if you choose a programmable radiator
  • The automatic start-up of the device thanks to a presence detector

#5 - Security accreditation

When you consider buying an electric heater, you should make sure that the product is validated by the appropriate safety accreditation programs. At the very least, your electric heater should carry the CE mark, which is the manufacturer's declaration that the device meets the minimum safety standards required by European legislation.

Safety rules for the installation and use of a dry heat radiator

Please read the safety instructions carefully before using a dry heat radiator.

  • This type of heater can be used by children aged 8 years and over, and by people with reduced mobility, but only under supervision.
  • Children should not play with the heater. Cleaning and maintenance by the user should not be done by unsupervised children.
  • Keep the unit out of the reach of small children.

CAUTION - Parts of a dry heat unit can become very hot and cause burns.

  • If the power cord is damaged, it must be replaced by the manufacturer, its service agent or other qualified persons to prevent accidents.
  • To prevent overheating, never cover a heater.
  • To avoid hazards due to thermal cut-out resets, a dry heat radiator should not be powered by an external switch, such as a timer, or connected to a circuit that is regularly turned on and off by the power source.
  • If located in the shower room, the heater should be installed so that the switches and other controls cannot be touched by a person in the shower or bathing. In this case, a 30mA RCD circuit breaker must be used.

Dry or fluid inertia radiator?

Dry inertia radiator

The dry inertia radiator is an even and gentle heating system. This is due to the fact that the temperature variations are less abrupt to provide the inhabitants of a house with a better thermal comfort.

The operating principle of the dry inertia radiator is based on the use of a solid heating body made of refractory material, ie resistant to heat. This material can be stone, cast iron, etc..

The electric resistance is placed in the heart of this refractory material to raise its temperature. The high level of thermal inertia of the materials that make up this type of radiator allows them to store heat efficiently when the appliance is in use.

A dry inertia radiator is more durable than a fluid inertia model and is best suited for high-traffic living areas. It is more expensive to purchase, but is a successful investment over the long term.

Inertia fluid radiator

This inertia heater uses heat transfer fluids to produce heat. It is operated by glycol, vegetable oil or mineral oil.

It is much less expensive than a dry inertia model, but heats just as quickly as the dry inertia model. The difference is that the dry inertia model is more robust and durable than a dry inertia heater.

The fluid inertia radiator offers the same feeling as with a central heating system. Contrary to the dry inertia radiator, it allows a faster rise in temperature while being voracious in electricity.


In terms of thermal performance, the two devices are equal. However, the choice between the two will depend on the surface to be heated. A small space of about fifteen square meters will need a heating at 20°C, which is the equivalent of a power of 1,000 W. The larger the space to be heated, the greater the power required of the heater.

Why buy a dry inertia heater?

For instant heat and gentle warmth

Because ceramic plates absorb heat, they can reach the desired temperature quickly, often faster than other types of radiators. Dry heaters are also known to generate gentle, non-smothering heat compared to fan heaters, thanks to the solid plates that heat up gradually before heating the room.

To save electricity

Once the heating plate reaches the set temperature, the electric current is turned off and the heat stored in the ceramic material continues to heat your room. This means that less energy is needed to produce more heat, so it is economical to operate and dry inertia heaters are environmentally friendly.

To be environmentally friendly

Compared to stoves using wood or fossil fuels such as gas, the efficiency of a ceramic radiator varies between 85 and 90%. These efficiencies are very comparable to other types of radiators, but they are also environmentally friendly.

For its compactness

Because they are so efficient, they produce a lot of heat despite their small size. This is an asset when your space is limited. The dry inertia heater is also the best alternative for heating larger rooms where you need a more powerful and discreet heat source.

To reduce the risk of fire from heating systems

Dry heaters are very safe because ceramic plates completely surround the heating elements, so there is no possibility of sparks that could cause a fire. They also have built-in safety features that facilitate the convection heating process and prevent overheating with a thermostat.

For less pollution

One of the great advantages of electric heaters over gas heating is that there are no harmful fumes emitted, such as the gas itself or the carbon monoxide that a faulty stove can emit when burned incorrectly.

Surface temperature limiter

To avoid burns, you will need to fit your electric heater with a thermal safety limiter that will cut off power to the heater if the surface temperature exceeds a set limit. This prevents your radiator from overheating and is especially important in homes with young children or vulnerable adults.


Most electric radiators are suitable for DIY installation. It's an easy task that requires minimal DIY skills. Radiators simply screw into the wall and plug into the nearest outlet, like a TV.
If you want to mount your radiator on a stand, make sure the radiator is available with a set of legs or wheels.
If you don't want to install the radiators yourself, you can pay an electrician to do the work. Electricians will mount the radiator for you and can also wire the radiator into the wall. This is recommended if you want a discreet installation without loose wires or plugs.


Any dry inertia radiator should not be thrown away with the regular garbage; it should be taken to a local electrical appliance collection and recycling center.

Best location for a dry inertia heater

The best place for a radiator is in the coolest part of the room. Under a window, for example. However, in more modern double-glazed homes, there may not be a cold area, so you can place radiators where they won't affect wall use. A general rule of thumb is to have a radiator about every 4 m in a room.

Locations to avoid for a heater

Wherever you choose to place it, try not to place your radiator behind large pieces of furniture, such as the sofa or cabinets. This will limit the flow of warm air into the room.


How to calculate the approximate power of an electric radiator?

To obtain the power of an electric radiator, you just have to multiply the surface by 100 W if your house is poorly or moderately insulated. On the other hand, if it is very well insulated, multiply the surface area by 60 W and by 125 W on average for the bathroom.

What is the difference between a dry inertia radiator and a fluid inertia radiator?

A dry inertia radiatorhas a ceramic or cast iron core. The fluid inertia radiator, on the other hand, offers a faster rise in temperature in particular, thanks to its metal heating body and the fluid that is inside. The latter spreads the heat more quickly throughout the body of the radiator.

Why are radiators positioned under a window?

Windows are traditionally the most insulated surfaces in a building envelope. In the 20th century, to combat this cold feeling and keep the room comfortably warm, radiators were always placed under a window. The rising heat from the radiator forms a kind of warm air curtain that protects you from the cold air.

Can I leave my radiator on all night?

It is not advisable to leave electric radiators on at night. Electric heaters can be a fire hazard, especially when placed near curtains, comforters, rugs and other materials often found in bedrooms.
