The terrestrial heat from the interior of our earth, is subsequently transferred to the earth's surface through convection of magma or deep water. This natural warmth that comes from underground can be exploited to generate geothermal energy is commonly defined , the adoption of such a system of energy use has a number of benefits that affect the ecological sphere together with the economic type.
For those who invest in them, are in fact expected contributions and funding as well as regional tax deduction of 55% of the cost of the installation, residential buildings adopting these energy systems are among those in compliance with existing containment energy consumption. The
geothermal plants produce greenhouse gas emissions significantly lower than those of other traditional systems, so using in your building heating and cooling with geothermal energy you get a major improvement in the energy classification of the building .
This facilitates the granting of building permits and increases the commercial value of property , as well as bringing considerable savings due to simplification of the plant system as a whole.
The same plant produces winter heating, summer cooling and hot water, all with complete safety, thanks to the absence of risk is present in its operation.
geothermal plants do not produce flames, do not emit gases or odors and do not present a risk of fire or explosion, they are considered as systems hydraulic system of management which do not require periodic inspection and maintenance, as needed for systems with boiler.
A significant example of intervention in the residential field of geothermal energy is that, International Geothermal Italy has proposed a geothermal district heating project for future subdivisions in the vicinity of Caversham.
The new residential complexes that will arise will have geothermal heating and cooling, taking advantage of the low temperature heat stored by a closed-loop probe with circular structure located deep in the ground.
Essentially, every household will have of a heat pump connected to this common probe that will release the stored heat to the buildings connected. International Geothermal Italy, finally, thought also to heating and cooling of the greenhouses in the area of \u200b\u200binterest in the project.
In this case, both winter and summer, the facility may have a temperature and humidity level constant, through the application of horizontal closed-loop sensors.
The solution is inexpensive because the probes are applied with a 1.5 to 2 m depth in the soil, require minimal digging, the more it is used twice in the broad ground on which there are the same greenhouses.
Particular attention should be paid to the phase of drilling, in economic terms it represents about one third of the cost of the system, are normally cost between 50-60 euro per ml. Drilling, we recommend that you contact companies credited with proven experience.
L ' no environmental impact, with the advantages listed, make this system a safe investment for environmental protection and public health.
