Solar energy offers two types of energies to know electrical energy and that which is thermal. The latter is used for the systems of solar-fired heater and solar heating, which is used more and more in this moment. The reasons are numerous but the principal one is that this system is more ecological compared to the traditional system.
Principles of this kind of heating
For those which do not know it, the system of the solar heating comes from a thermal and not photovoltaic solar energy source. The concept of this combined solar system is most widespread on the matter. In this case, the solar energies stored by the solar panels will be used as system of medical heating of water but also in all the dwelling.
The panels used in this system have a solid and glazed aspect. Several elements are built-in there as a plate as its absorbers which will box the solar radiations. That will heat coolant before distributing them on various equipment intended to receive it.
In truth, it is thanks to coolant that the medical warm water will be heated and that heat will be distributed in the network of heating. In this process, there exists a balloon which will preserve the water of heating after this one passed by a heat exchanger. This balloon will then supply the radiators of the house to bring a more pleasant heat there. In this concept of solar compound, it is important always to preserve a traditional boiler holds some for the less sunny seasons.
With the system of solar heating thermal, the occupant of the house saves 70% of his medical warm water expenditure but also 40% in heating. He thus gives to the dwelling an independence with respect to fossil energies what contributes effectively to environmental protection.
Generally, this system is very adapted in the areas of sunny like those in the south of France for example. For the others, it is necessary to make the choice between geothermics, the unit heater and wood energy.
Solar energy compared to the ordinary heating
In spite of its effectiveness, the solar heating system especially requires certain installations in flagstone of storage, bioclimatic approach or insulation. It is said that it can replace the traditional system, which is however not founded.
In fact, it is only one complement not a substitute of the traditional heating. It thus makes it possible only to reduce the expenditure which there are dependant and especially the emissions gas which come there. The solar heating system makes it possible to satisfy the daily needs in the house in particular with regard to heat at the time of the sunny seasons. The traditional system as for him, will be quite useful for the covered nights and seasons.
Compared to the energy sources of ordinary heating, the solar heating costs more expensive not only the moment at the time of the purchase than of the installation. However, it is on the long run that it is most profitable. The expenses of electricities will be less low because the system which is attached there is less frequently used. The solar one will thus take over when it is made beautiful. |
