When building or renovating a house, or even before moving in, the first criterion to focus on is the heating method: Fan heater, Soft Heat Radiator, Ceramic Radiator, Fluid inertia radiator, etc. The choice of radiators is made according to their ability to provide gentle and homogeneous heat in the room, regardless of its size. These heaters have improved performance today and are available in many models. While some are cheaper to buy, they can still consume more energy, and vice versa. What type of radiator is right for your needs? Find out the answers in our article.
How a radiator works
This type of heater has two heat distribution modes: by convection and by radiation. Generally, radiators use these two energies.
The phenomenon of convection
The heat transfer takes place through the movement of air. This is because the air molecules that come into contact with the heating surface of the radiator are heated before being diffused throughout the room. As you probably already know, the air near the ground is cooler. It is taken by the convector which takes care of heat it up with an electric resistance before spreading it outside. As the air is in constant movement, the cold molecules immediately replace those spread in the space to be heated, thus causing a permanent stirring movement.
However, the convector's biggest drawback is its energy-intensive nature. In addition, the heat emitted is harsh and only spreads over a limited area. As a result, the further away from the radiator, the lower the temperature, unlike the Fan heater which allowsinstantly achieve the desired temperature throughout the room. On the other hand, the convection heater is also known to dry out the air, which can have deleterious effects on the health of the occupants of the house.
The phenomenon of radiation
The principle of operation of this heat diffusion mode is based on the emission of electromagnetic waves. Being able to be diffused instantly in all directions, these infrared waves have the particularity of being able to transport heat in a uniform way throughout the room. More thrifty, this type of heater has clean lines and blends easily into the decor. Ultra-thin models to hang on the wall, like the Wall Fan Heater, invade interiors in recent years.
However, a radiator with radiant panels is less efficient than a device using the phenomenon of convection. This is because electromagnetic waves are less powerful and, therefore, carry less heat. As a result, the temperature in the room is lower, sometimes with a clear difference between the floor and the ceiling. In addition, this type of heater also dries the air and can cause yellow streaks to appear on the walls.
The different types of radiators
With the multiplicity of devices available on the market, the most prestigious brands as well as the lesser-known ones are launching a merciless war to carve out market share. These offer a wide choice of models specifically designed to meet the needs of consumers. in terms of design, power, programming and heating comfort, among others. Among the most popular are the Acova radiator. There are currently three main types.
The water radiator
Connected to a boiler, the hot water radiator is appreciated for exceptional thermal comfort that he offers. In fact, by heating the water (heat transfer liquid) circulating in its ducts at low temperature, the Soft Heat Radiator offers a temperature of 50 ° C. The hot water radiator is also capable of emitting strong heat, with a temperature up to 90 ° C. The latter uses more energy, but is able to heat the ambient air more quickly, just like the blower heating. The hot water radiator is used for combustion heaters (wood, oil or gas), solar heating and the heat pump. The heat diffusion can be effected by radiation or by convection.
The inertia radiator
This type of heating is particularly appreciated for its ability to heat the room even when it is off. In fact, the refractory element located in the center of the device is designed to store heat when the device is plugged in. Once turned off, this system continues to release the stored heat, allowing you to perform considerable savings on your electricity bill. In addition, heat is emitted so homogeneous for unparalleled thermal comfort. This device is available in two main categories: dry inertia radiator and fluid inertia radiator.
- The dry inertia radiator consists of several refractory plates available in many materials (soapstone, soapstones, marble, granite, etc.). The gentle heat is diffused via its envelope made up of an emissive surface specifically designed for this purpose. Some models, such as Ceramic Radiator, allow significant energy savings of up to up to 40%.
- The Fluid inertia radiator is equipped with electric heaters intended for heat the coolant which circulates in the device in a closed circuit. Typically, it can be oil (mineral or vegetable) or glycol water (petroleum derivative).
The electric heater
Representing the most popular heating method in France (present in more than 9.5 million homes) following a renewed offer, the electric heater offers several advantages. Increased power, shorter heating time, high inertia power… Its operating method has been revised down to the smallest detail to appeal to consumers. With technological progress, electric heating offers optimum heat evenly, and this without any loss. A wide choice of options is available to allow you to enjoy unparalleled thermal comfort while achieving significant energy savings. For heating large rooms, choose a Ceramic Fan Heater, appreciated for its silent character. It is possible to program the start or stop of this device.
