Alternatives to polluting energy sources exist for some yearsHeating can be quickly overhead expense budget especially during winterUse of alternative energy such as geothermal and aerothermal can be very interesting with an expenditure of 3 to 5 times less expensive than traditional energyIt is why heat pumps according to the needs and possibilities of each
The pump aerothermal
Aerothermal pump uses heat from the air to distribute the heat within a building structureThe air is a renewable resource and free, a heat pump (CAP) is very effective aerothermal heat a house
Particularly suitable for all types of construction, the air APC differ depending on whether they are air-air or air-waterThe operating principle is identicalIt is based on the flow of a fluid, which stores energy from the air and distributes it through two units responsible for capturing and sending the energy trapped
The distinction is the method of distribution of the heat absorbedThe first uses a fan coil, while the second uses a capacitor combined with the conventional heating system
Although the air-CAP does not benefit from tax credit on the installation, acquisition costs are relatively low compared to those of a geothermal plantHowever, grants may be obtained from the decentralized authorities
CAP air-water has its part of a tax credit of 22% on hardware
The effectiveness of the CAP air is obtained by calculating the coefficient of performance heat pump or COPTo optimize the COP CAP air of an installation, it is always better to combine its use with means for heating type electricThe COP varies in effect depending on weather conditions and installation
The COP of a CAP air is between a level 3 and 4 for water and air-PAC 2 and 3 for the air-
The heat pump
The geothermal heat pump works on almost the same principle as the air pumpHowever, its operation is based on horizontal or vertical sensors that are responsible for capturing energy from the groundIt is then distributed through fan coils or radiators or by floorsFor floor heating the house must have specific facilities with central heating
CAP geothermal installation is more difficult to install, but is also more expensiveThe work to be done are more important and installation is also conditioned by the specifics of the field size, geological ...
The advantage is that you can receive substantial tax creditsThus, this type of installation will bring you up to 36% discount on equipment needed
The COP of a geothermal development is quite interesting with a yield of 3 to 5 kWh of heat for a power consumption of 1 kWhBecause you obviously can not do without completely EDF Energy to run some geothermal features of the CAP, but also for the CAP air
Remember also that to use this type of pump, an authorization of the City of your jurisdiction is required |
