Radiators
Choosing the right radiator is essential for enjoying a comfortable home without driving up your electricity bill. At Bestherm, our electric radiators combine thermal performance, innovative technologies and contemporary design to meet every need. Dry inertia, connected heating or dual heating cores: each solution is designed to provide lasting comfort while keeping your energy consumption under control.
Which electric radiator should you choose for your home?
The right radiator is not necessarily the most powerful: above all, it must be suited to your home and your lifestyle. Room size, insulation, how often the room is occupied and your budget are all factors to consider before making your choice.
At Bestherm, every radiator is designed to provide pleasant heat, maintain a stable temperature and simplify everyday heating. Quality materials and precise regulation help improve comfort while keeping energy costs under control.
Dry-inertia radiator: gentle, even comfort (Ceramic & Cast iron)
A dry-inertia radiator stores heat in a refractory material before gradually releasing it. This operation ensures a stable temperature, limits temperature fluctuations and improves comfort while reducing electricity consumption.
There are two main technologies:
- Cast-iron electric radiators offer exceptional thermal inertia thanks to their ability to store and then gradually release heat.
- Ceramic dry-inertia radiators stand out for their faster heat-up time while retaining the benefits of gentle, even heat.
Other technologies, such as heat-transfer fluid, natural convection and infrared radiation, also meet certain specific needs, but dry inertia remains the benchmark today for combining comfort and energy savings.
Connected and smart radiator: take control of your energy consumption
The connected electric heater lets you control your heating from your smartphone, wherever you are. In just a few seconds, you can change the programming, adjust the temperature of each room, or turn off an appliance that has been left on. This way, you retain control over your consumption, even when you are away.
Equipped with a programmable thermostat, the smart electric heater automatically adapts heating periods to your lifestyle. You heat only when necessary, naturally reducing electricity consumption. According to ADEME*, suitable programming can achieve up to 30% energy savings.
Dual-core heating & film models: combining rapid heat-up and temperature maintenance
Dual-core heating electric heaters combine a highly responsive heating film with an inertial core to provide a rapid temperature increase without sacrificing long-lasting comfort.
In a living room or large living space, this technology provides almost immediate warmth while maintaining a stable temperature for several hours. Comfort is felt quickly without repeatedly restarting the heating.
How do you correctly determine the wattage of your heater?
To estimate the right wattage, the most commonly used rule is to allow approximately 100 W per m² in a properly insulated home. This estimate provides an excellent starting point before refining it based on the room's exposure or insulation level.
Insulation performance, the room's exposure, and large windows may require an adjustment to this wattage.
To sustainably limit your consumption, energy-efficient electric heaters combine thermal inertia, high-performance electronic regulation, and smart programming to optimize each heating period.

Key features of Bestherm radiators
Every day, several features help improve comfort while limiting energy costs. Bestherm radiators incorporate technologies designed to provide smarter, more economical heating that is easier to use.
They are compatible with centralized control via pilot wire, feature weekly programming, a programmable thermostat, efficient electronic regulation and an IP24 protection rating, suitable for different rooms in the home.
All Bestherm radiators comply with European requirements and bear the CE marking**. Some models also hold NF Électricité certification***, a guarantee of quality, safety and energy performance.
Open-window and presence detectors
When airing the room, the radiator with open-window detection automatically detects a sudden drop in temperature and reduces its power to avoid unnecessary consumption. It therefore reduces its power to avoid heating unnecessarily while the windows are open.
Models equipped with an integrated presence detector automatically adjust their operation according to room occupancy, improving comfort while limiting unnecessary energy consumption.
Interchangeable thermostat and easy maintenance
Designed to support your home over the long term, this technology focuses on a durable, upgradeable design. The interchangeable thermostats allow you to replace only the control system when necessary, without having to replace the entire radiator.
This design makes maintenance easier, reduces maintenance costs and extends the lifespan of your equipment.
FAQ: Everything you need to know about electric radiators
Which electric radiator is the most economical to run?
A cast-iron or ceramic dry-inertia radiator equipped with a smart thermostat is currently the most economical solution. It continues to distribute gentle heat after the heating element switches off, limiting heating cycles and reducing electricity consumption.
- Gradual heat distribution.
- High-precision programmable thermostat.
- Weekly programming.
- Up to 30% energy savings depending on usage.
What is the difference between a cast-iron radiator and a ceramic radiator?
Cast iron has greater thermal inertia and retains heat for a very long time. Ceramic heats up more quickly while providing excellent comfort for everyday use.
- Cast iron: ideal for large spaces.
- Ceramic: more responsive when starting up.
- Both provide even, pleasant warmth.
How much radiator power is needed per m²?
For a properly insulated home, allow approximately 100 W per m² (or 40 W per m³). A 15 m² room will generally require a 1500 W radiator.
- Allow for more power if the insulation is old.
- Adjust the power according to the room's exposure.
- Take ceiling height into account.
Why choose a connected electric radiator?
A connected radiator lets you control the temperature remotely, schedule heating periods and monitor its electricity consumption. This intelligent management can save up to 30% on energy while improving comfort.
- Control from your smartphone.
- Personalized programming.
- Energy consumption monitoring in kWh - depending on the model.
- Temperature adjusted room by room.
To equip your bathroom as well, Bestherm electric towel radiators offer the same level of quality, thermal performance and comfort as the entire radiator range. If you want an even faster rise in temperature, a fan-assisted electric towel radiator is an ideal solution for heating the room while keeping your towels at the right temperature.
