How to choose your connected electric radiator

Due to the large number of connected electric radiator models on the market, it has become very difficult to find your way around. But don't panic, the following criteria will surely help you find the one that suits your needs.

#1 - The heating mode

The first element to consider when buying a connected electric heater is its heating system. This can be convection, radiation, inertia or dual heating system. The last two are the most interesting, as they offer many more advantages.

The inertia heating mode (dry or fluid) provides excellent thermal comfort and even heat, while achieving significant energy savings. The appliances that have it can keep the heat and give it back when you turn them off.

The dual heating system allows you to take advantage of two heating modes: convection and inertia. Dual system heaters heat a room more quickly and gently, and can continue to heat even if you turn off their power sources.

#2 - The degree of intelligence

Once you've found the connected electric heater with the right heating system for you, the next thing to check is its level of intelligence. Some models are equipped with a presence sensor. This allows them to automatically start heating when you enter the room.

Others are more intelligent and can offer additional technologies. For example, they can adapt the heat level according to your habits or stop working when the windows are open to better save energy.

#3 - The power

The power is also an important factor when choosing a connected electric heater. It is 100 watts per m2 under a 2.5 m ceiling. It should therefore vary according to the size of the room to be heated.

But for optimal thermal comfort, you must also take into account the geographical area of your home, the thermal insulation of the room and its exposure to sunlight. For example, a powerful radiator is necessary if you live in a colder region.

#4 - The control system

Remote control of a connected electric radiator is only possible using a wireless network. Some radiators are controllable via Bluetooth, while others need an internet connection (wifi). The latter are the most popular, as their network range is not limited. You can control them wherever you are. Their applications are also more sophisticated and feature-rich.

With this connection system, it is for example possible to pair up several connected devices, to set time slots, to change the temperature room by room, etc. This is very useful for managing energy consumption. However, a connection module (Bridge Cozytouch, Muller Intuitiv with Netatmo, etc.) is required to make this possible. This additional equipment serves as a relay between the thermostat and the smartphone.

#5 - The dimensions

The last thing to consider when choosing a connected electric radiator is its size. This depends on where you want to hang it, but mostly on your type of wall. If your wall is built of solid masonry, i.e. bricks or blocks, you are free to choose the one with a style that best suits your room.

Large connected electric heaters can indeed be hung on solid walls. Otherwise, if your wall is made of plasterboard, you will definitely need to identify the strongest part. However, avoid installing your heater behind large pieces of furniture, as this prevents heat from circulating in the room.

How do I clean a connected electric heater?

Dust and dirt can easily accumulate on the finned tubes of your connected electric heater. When this happens, it needs more power to heat and can increase the amount of energy consumed.

For effective cleaning, you'll need a screwdriver, a sponge or microfiber cloth, a vacuum cleaner with a small nozzle and a spray bottle.

First, make sure the heater is off.Unscrew and remove its cover if there is one. Remove dry dust and debris with the vacuum cleaner. Target the tight spaces of the connected electric heater with the small nozzle well. However, avoid touching the wires. For this you can wrap a cloth around a long piece of wood to gently move it up and down to remove the dirt.

Then, for very sticky debris,lightly wet a sponge with soapy water and run it over all interior surfaces. Avoid spraying water directly on its surface. However, skip this step if your connected electric heater has a non-removable cover. Don't forget to place a special cloth under the connected electric heater to collect the dust.


Finally, perform regular cleaning. Connected electric heaters don't require much attention and maintenance, but they do need to be cleaned regularly. So make sure your heater is cleaned thoroughly once or twice a year. Clean your connected electric heater once every two weeks, especially during the winter.

The different types of connected electric heaters

The connected electric radiator comes in 4 types, namely the convector model, inertia, radiant panel and the two-core electric radiator.

Electric convector radiator

This type of radiator works with resistances. These heaters are heated to diffuse heat. This model is the first to appear on the market. It is very practical to make the air more homogeneous in a house. Its manufacturing cost is low, so it is inexpensive and more accessible. But it still has the disadvantage of being less efficient. Indeed, it takes a lot of time to warm up a room.

Electric inertia radiator

An electric inertia heater provides a better comfort of use. It heats much longer without generating more expenses, compared to other types of connected electric radiators. Its real strength is that it distributes heat evenly, from the floor to the ceiling, and even to other rooms.

The electric inertia radiator exists in 2 models: fluid inertia or dry inertia. The first one contains liquid (glycol water, derived from petroleum or vegetable oil) which spreads in the radiator to disperse heat. This fluid is also heated by thermoplastic electric resistances.

The dry inertia electric radiator consists of a heating core made of several materials. It is more efficient than the fluid model. Indeed, its accumulation capacity is more improved.

Radiant panels

This model is especially suitable for small rooms. It diffuses heat by radiation. Unlike other types of connected electric radiators, radiant panels heat objects in a room that retain heat through radiation. It is therefore the ideal model to obtain a gentle temperature. However, its heat diffusion is not homogeneous.

Dual heating system electric radiator

Polyvalent, this type of connected electric radiator has 2 cores. It has the particularity of heating even faster, because it is both a radiant panel and inertia. When the desired temperature is reached, the radiation stops and stores heat. It is the inertia that starts up afterwards.

Connected electric radiator or connected wood stove?

Connected electric radiator

An electric heater is a type of home heating system that runs on electricity, and can be controlled remotely through the use of a wireless network (Bluetooth, Internet). Its control is done via an application installed in your smartphone or tablet. The first great advantage of the connected electric radiator is that it allows you to manage the heating of your home from a distance. It is also a smart device. Indeed, it can turn on or off automatically and operate according to your habits. All this helps you to limit heat loss and save a lot of money.

Connected electric heaters are the cheapest connected heaters on the market. They are easy to install and don't require a large initial budget. They are also easy to use and offer many features in their applications. For example, they can predict your energy consumption. However, despite these many advantages, these devices also have some disadvantages. They are more energy intensive compared to other types of connected and smart heaters. Their average annual operating cost is among the highest. In addition, this heating system is generally suitable for small spaces.

Connected wood stove

The connected wood stove is an automated and programmable heater that works with wood (logs or pellets). It is also controlled remotely from a smartphone or tablet via an application developed by its manufacturer. The heat output can be adapted to your lifestyle and you can also monitor your energy consumption. It therefore allows you to save energy. The connected wood stove has the lowest average annual operating cost of all types of connected heaters. Indeed, wood is a very affordable energy and costs 2 times less than electricity.

The connected wood stove provides an excellent thermal comfort, it sends a constant and pleasant heat. It is also an ecological device since it uses a renewable energy. In addition, this type of heating is considered by the State as a clean energy and those who buy it benefit from aid and a tax credit to reduce the initial investment. The latter is indeed enormous and constitutes its greatest disadvantage. In addition, this type of heating is mainly suitable for houses, but not for apartments, because its smoke must be evacuated. Finally, it is less intelligent and more limited in terms of automation.


These two heating systems are all controllable from a smartphone or tablet. They do not waste energy. The wood stove is the most economical in terms of operating cost. However, the connected heater is more convenient. It is also the most versatile because, it is suitable for all types of habitats.

Why buy a connected electric heater?

Monitor your consumption

Most connected electric radiators come with a monitoring app to access your consumption statistics. Monitor which of the connected electric radiators are using the most energy and adjust the settings for better efficiency. It's even possible to get more information about your rates with the more sophisticated apps to calculate actual costs, which will help you keep your bill down.

Manage the heat in each room of your home

One of the great benefits of connected electric radiators is that you can customize heating programs for each room. This means you should only turn on what's in those rooms. This helps you keep operating costs to a minimum.

Perform weekly programming on your connected electric heater

To maximize the efficiency of your heater, it's ideal to perform weekly scheduling. This involves having it turn on and off at a set time during the day. For example, you turn it on when you wake up and turn it off before you leave the house. This way, it will adapt to your routine and allow your heating to stay in sync and most importantly save more.

Check the electrical connections

A connected electric heater will not work if there is a disconnection. Before confirming that it's down, make sure there's a connection. That is, make sure the plug is securely attached to the wall.

Balance your heating system

Some connected electric heaters may be a little hotter than others. Generally, this means that your central heating system is out of balance. If you don't want to call in a specialist, you can:

  1. First, locate the balancing "T" on your units.
  2. Remove the cap with a screwdriver to access the balancing screw.
  3. Use a BTR wrench depending on the model of your connected electric heater
  4. Close all return tees on each unit.
  5. Open the one closest to the boiler by one turn, increase the screw opening by half a turn depending on the distance from the boiler.


How to connect a wireless room thermostat to the electric radiator?

First of all, an electric heater is an electrical device that converts electric current into heat. A connected electric heater is equipped with a remote control system that works through wireless communication. All you need to do is to connect a radio receiver to the device. Then connect the pilot wire to the receiver. It is through this simple process that you can control it remotely through an app.

What type of connected electric radiators consume the least electricity?

This is the electric inertia heater. Indeed, it has not only a perfect inertia, but also an excellent heat diffusion by radiation. This makes it considered the least consuming.

How to check if a connected electric radiator is working properly?

The first reflex to have is to check if your device turns on by pressing the power button. If the indicator light comes on, it is more than obvious that the connected electric heater is working. The most common cause of a malfunction is a blown fuse. If this is the case, you can replace the fuse, reconnect the device and turn it on again.

Is it possible to know if a radiator consumes a lot of electricity?

The general answer is yes. But to find out the exact consumption, you should do a little math. For example, if your connected electric heater is 1000 watts its power is 1 kWh. So to know your monthly consumption, the formula is price per kWh × power (in kWh) × 24 (hours) × 30 (days). So for a connected electric radiator of 1000 W, the monthly consumption is 87.48 €.
