The technologies of electric heaters on the market in 2019: what to choose for your project?
Heat a home fromrenewable energies significantly reduces electricity costs. Unfortunately, many people can not opt for renewable energy (RE) heating solutions because of the incompatibility of these types of devices with their good. In case you can not take advantage of thesolar energy, wind power or geothermal energy to heat the interior of your home, know that you can always save money by turning to the new generation radiators.
They are much less energy-consuming than the traditional "toasters" and incorporate various technologies to significantly improve the thermal comfort of your home without inflating your bill. Overview of different types of new generation radiators: their functioning, their strengths and their weaknesses.
Modern radiators with natural convection
These types of radiators are simply "toasters", but they are smart, by embedding technologies to reduce, to a certain extent, electricity consumption and better manage heating schedules.
Like their elders, they use natural convection to spread heat in a home. Cold air is drawn from the bottom of the unit and heated by resistance. It then emerges from grilles or fins, and continues to climb to the ceiling. As its temperature drops, it goes down to ground level and is again taken by the radiator to be warmed up.
The main assets of the natural convection heater reside in its particularly affordable price (a few tens of euros) and in its installation, achievable by a handyman amateur. However, if you want to efficiently optimize the thermal comfort of your home while reducing your energy consumption, we recommend that you turn to another type of model. Indeed, this radiator is relatively energy-intensive and does not distribute the heat homogeneously.
These radiators are like excellent alternatives to natural convection models. They radiate heat, and can reduce their operating time thanks to a solid or liquid heating core.
This heart (or body) of heating has the main function of keep the heat produced by the device, to then restore it gradually inside your home. At times, the inertia radiator greatly reduces its electricity consumption to allow the heating of your home to a coolant or a refractory material such as cast iron or aluminum.
This type of device is simply a must to limit your expenses, while improving the thermal comfort of your home. However, it has some weaknesses among which we can mention its relatively long heating time and its purchase price significantly higher than that of conventional convection heaters.
Radiator (panel) radiating
The radiant panel radiator combines the advantages of the inertia and natural convection models, respectively. As its name suggests, it has a panel whose role is to to diffuse the heat by electromagnetic radiation
This element can be made of carbon or metal alloy. It is heated thanks to electric resistances, and restores the heat produced inside your home, by diffusing infrared rays over great distances.
The radiant panel radiator is more energy efficient than a conventional convector. In addition, it takes less time to heat a room than an inertia model. However, it does not offer the same level of comfort as so-called "soft heat" devices and can result in dispersions of allergens and microparticles due to its radiation system.
For information, this heater is both compact and design. Many brands are putting their creativity to work to make their products real decorative pieces. There are even radiant mirrors, especially for bathrooms!
Dual core heating radiators
Dual-core radiators are both economical and efficient. Like the inertia models, they are equipped with a cast iron or ceramic heater that can effectively store heat and heat. reduce energy consumption.
But in addition to the heating core of refractory material, this type of heating system is equipped with a radiating panel. It is responsible for rapidly generating heat through the diffusion of infrared rays over long distances.
The two bodies of this radiator work alternately, in order to reduce the heating time, to limit energy consumption and to guarantee optimal comfort. At first, the radiant panel warms the air and diffuses it in your room, your bathroom or your living room. As soon as the body of refractory material reaches a certain temperature, it takes over and the device adjusts its consumption so that you can achieve significant energy savings.
Thanks to the combination of these two technologies, the dual-core radiator is more economical than modern convectors, and guarantees a level of comfort similar to that of inertia devices. However, it is not free of weaknesses: on the one hand, it is more expensive than natural convection heaters and, on the other hand, it often requires you to proceed to a number of settings to effectively adjust the ambient air temperature of your home.
Note that the first dual-core heating systems appeared in the 90 years. They were known as "2 1 Radiant", and combined radiation and convection panels, like the current panel radiators.
Electric heating walls and floors
The configurations of walls and heated floors are very different from those of conventional radiators because they are integrated in walls and floors. However, they have some characteristics of radiant radiators but their power density is much lower, which increases thermal comfort and energy savings. This is the mode of heating The most comfortable and economical electric, but it requires quite heavy installation work.
Indeed, they are placed under the floor or under the coating or wall covering which requires to redo one or the other entirely. This mode is therefore reserved for renovations or new constructions. They are therefore much more expensive to install than convectors, radiator, radiator and double-core heaters.
